  • StructureMap Issue in Initializing the Dependencies

    - by azamsharp
    I am performing some unit tests and want my MembershipProvider to initialize the dependencies. I run the following code before any test is executed [TestFixtureSetup]. public static void StructureMapConfiguration() { ObjectFactory.Initialize(InitializeUsingScanning); } private static void InitializeUsingScanning(IInitializationExpression obj) { obj.Scan( x => { x.Assembly("EStudyMongoDb.Business"); x.WithDefaultConventions(); } ); } Here is my EstablishContext method which is triggered before running any test: public override void EstablishContext() { _provider = ObjectFactory.GetInstance<MongoDbMembershipProvider>(); _config.Add("applicationName", "EStudyApplication"); _config.Add("name", "EStudyMembershipProvider"); _config.Add("requiresQuestionAndAnswer", "false"); _provider.Initialize(_config["name"], _config); } Here is my test: [TestFixture] public class when_creating_a_new_user : specification_for_membership_provider { public override void When() { _user = _provider.CreateUser("johndoe", "password", "[email protected]", String.Empty, String.Empty, true, null, out _status); } [Test] public void should_create_successfully() { var vUser = Membership.GetUser(_user.UserName); Assert.IsNotNull(vUser); } } Now, in the Membership.GetUser method I try to access the _userRepository but I get null.

  • t-sql most efficient row to column? crosstab for xml path, pivot

    - by ajberry
    I am looking for the most performant way to turn rows into columns. I have a requirement to output the contents of the db (not actual schema below, but concept is similar) in both fixed width and delimited formats. The below FOR XML PATH query gives me the result I want, but when dealing with anything other than small amounts of data, can take awhile. select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o I've looked at pivot but most of the examples I have found are aggregating information. I just want to combine the child rows and tack them onto the parent. I should also point out I don't need to deal with the column names either since the output of the child rows will either be a fixed width string or a delimited string. For example, given the following tables: OrderId CustomerId ----------- ----------- 1 1 2 2 3 3 DetailId OrderId ProductId ----------- ----------- ----------- 1 1 100 2 1 158 3 1 234 4 2 125 5 3 101 6 3 105 7 3 212 8 3 250 for an order I need to output: orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250 or orderid Products ----------- ----------------------- 1 100|158|234 2 125 3 101|105|212|250 Thoughts or suggestions? I am using SQL Server 2k5. Example Setup: create table _orders ( OrderId int identity(1,1) primary key nonclustered ,CustomerId int ) create table _details ( DetailId int identity(1,1) primary key nonclustered ,OrderId int ,ProductId int ) insert into _orders (CustomerId) select 1 union select 2 union select 3 insert into _details (OrderId,ProductId) select 1,100 union select 1,158 union select 1,234 union select 2,125 union select 3,105 union select 3,101 union select 3,212 union select 3,250 using FOR XML PATH: select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o which outputs what I want, however is very slow for large amounts of data. One of the child tables is over 2 million rows, pushing the processing time out to ~ 4 hours. orderid Products ----------- ----------------------- 1 100 158 234 2 125 3 101 105 212 250

  • python VTE Terminal weirdness

    - by mykhal
    i'm trying to use the terminal from python VTE binding (python-vte from debian squeeze) as a virtual terminal emulator (just for ANSI/control chars text processing) in interactive python console, everything looks (almost) all right: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) 'a\n b' however, launching this code (little modified) as python script, different result is yielded: $ python vte_wiredness_1.py '' strangely enough, pasting the code back into the (new) interactive python session also yields empty string: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) '' >>> first thing caming on my mind was that the only difference between the two cases is the timing - there had to be some delay before get_text. unfortunately, preluding get_text with some seconds sleep did not help then i thought it has something to do with X window environment. but the results are the same pure linux console (with some warning on missing graphics). i wonder what causes such an unpredictable behavior (interactive console - pasted vs typed, and it's not the delay.. ant the interactive console has nothing to do with the vte terminal object.. i guess) can someone explain what is happening? is it possible to use the VTE Term such way? that the "b" letter in the output is preceded by the space, is another strangeness (all consecutive lines are preceded by more spaces.. looks like I have to send carriage return before the string.) (the lambda *a: True get_text method argument i'm using is a dummy callback, it's is some SlotSelectedCallback.. for its explanation i'd be grateful as well :) )

  • Escape Quote in C# for javascript consumption

    - by Jason
    I have a ASP.Net web handler that returns results of a query in JSON format public static String dt2JSON(DataTable dt) { String s = "{\"rows\":["; if (dt.Rows.Count > 0) { foreach (DataRow dr in dt.Rows) { s += "{"; for (int i = 0; i < dr.Table.Columns.Count; i++) { s += "\"" + dr.Table.Columns[i].ToString() + "\":\"" + dr[i].ToString() + "\","; } s = s.Remove(s.Length - 1, 1); s += "},"; } s = s.Remove(s.Length - 1, 1); } s += "]}"; return s; } The problem is that sometimes the data returned has quotes in it and I would need to javascript-escape these so that it can be properly created into a js object. I need a way to find quotes in my data (quotes aren't there every time) and place a "/" character in front of them. Example response text (wrong): {"rows":[{"id":"ABC123","length":"5""}, {"id":"DEF456","length":"1.35""}, {"id":"HIJ789","length":"36.25""}]} I would need to escape the " so my response should be: {"rows":[{"id":"ABC123","length":"5\""}, {"id":"DEF456","length":"1.35\""}, {"id":"HIJ789","length":"36.25\""}]} Also, I'm pretty new to C# (coding in general really) so if something else in my code looks silly let me know.

  • Comparing textbox.text value to value in SQL Server

    - by Anicho
    Okay so I am trying to compare a login textbox password and username with a custom validator using linq to get information from the database it always returns false though on the validator could someone please tell me where my code below is going wrong. This will be very much appreciated... thank you in advanced... protected void LoginValidate(object source, ServerValidateEventArgs args) { TiamoDataContext context = new TiamoDataContext(); var UsernameCheck = from User in context.Users where User.Username == TextBoxLoginUsername.Text && User.Password == TextBoxLogInPassword.Text select User.Username; var PasswordCheck = from User in context.Users where User.Username == TextBoxLoginUsername.Text && User.Password == TextBoxLogInPassword.Text select User.Password; String test1 = PasswordCheck.ToString(); String test2 = UsernameCheck.ToString(); if (test1 == TextBoxLogInPassword.Text && test2 == TextBoxLoginUsername.Text) { args.IsValid = true; Session["Username"] = TextBoxLoginUsername; Response.Redirect("UserProfile.aspx"); } else { args.IsValid = false; } } I dont know where I am going wrong I know its most probably some sort of silly mistake and me being inexperienced at this...

  • How to call a service operation at a REST style WCF endpoint uri?

    - by Dieter Domanski
    Hi, is it possible to call a service operation at a wcf endpoint uri with a self hosted service? I want to call some default service operation when the client enters the endpoint uri of the service. In the following sample these uris correctly call the declared operations (SayHello, SayHi): - http://localhost:4711/clerk/hello - http://localhost:4711/clerk/hi But the uri - http://localhost:4711/clerk does not call the declared SayWelcome operation. Instead it leads to the well known 'Metadata publishing disabled' page. Enabling mex does not help, in this case the mex page is shown at the endpoint uri. private void StartSampleServiceHost() { ServiceHost serviceHost = new ServiceHost(typeof(Clerk), new Uri( "http://localhost:4711/clerk/")); ServiceEndpoint endpoint = serviceHost.AddServiceEndpoint(typeof(IClerk), new WebHttpBinding(), ""); endpoint.Behaviors.Add(new WebHttpBehavior()); serviceHost.Open(); } [ServiceContract] public interface IClerk { [OperationContract, WebGet(UriTemplate = "")] Stream SayWelcome(); [OperationContract, WebGet(UriTemplate = "/hello/")] Stream SayHello(); [OperationContract, WebGet(UriTemplate = "/hi/")] Stream SayHi(); } public class Clerk : IClerk { public Stream SayWelcome() { return Say("welcome"); } public Stream SayHello() { return Say("hello"); } public Stream SayHi() { return Say("hi"); } private Stream Say(string what) { string page = @"<html><body>" + what + "</body></html>"; return new MemoryStream(Encoding.UTF8.GetBytes(page)); } } Is there any way to disable the mex handling and to enable a declared operation instead? Thanks in advance, Dieter

  • slow SQL command

    - by Retrocoder
    I need to take some data from one table (and expand some XML on the way) and put it in another table. As the source table can have thousands or records which caused a timeout I decided to do it in batches of 100 records. The code is run on a schedule so doing it in batches works ok for the customer. If I have say 200 records in the source database the sproc runs very fast but if there are thousands it takes several minutes. I'm guessing that the "TOP 100" only takes the top 100 after it has gone through all the records. I need to change the whole code and sproc at some point as it doesn't scale but for now is there a quick fix to make this run quicker ? INSERT INTO [deviceManager].[TransactionLogStores] SELECT TOP 100 [EventId], [message].value('(/interface/mac)[1]', 'nvarchar(100)') AS mac, [message].value('(/interface/device) [1]', 'nvarchar(100)') AS device_type, [message].value('(/interface/id) [1]', 'nvarchar(100)') AS device_id, [message].value('substring(string((/interface/id)[1]), 1, 6)', 'nvarchar(100)') AS store_id, [message].value('(/interface/terminal/unit)[1]', 'nvarchar(100)') AS unit, [message].value('(/interface/terminal/trans/event)[1]', 'nvarchar(100)') AS event_id, [message].value('(/interface/terminal/trans/data)[1]', 'nvarchar(100)') AS event_data, [message].value('substring(string((/interface/terminal/trans/data)[1]), 9, 11)', 'nvarchar(100)') AS badge, [message].value('(/interface/terminal/trans/time)[1]', 'nvarchar(100)') AS terminal_time, MessageRecievedAt_UTC AS db_time FROM [deviceManager].[TransactionLog] WHERE EventId > @EventId --WHERE MessageRecievedAt_UTC > @StartTime AND MessageRecievedAt_UTC < @EndTime ORDER BY terminal_time DESC

  • Can I serialize an object if I didn't write the class used to instantiate that object?

    - by Richard77
    Hello, I've a simple class [Serializable] public class MyClass { public String FirstName { get; set: } public String LastName { get; set: } //Bellow is what I would like to do //But, it's not working //I get an exception ContactDataContext db = new ContactDataContext(); public void Save() { Contact contact = new Contact(); contact.FirstName = FirstName; contact.LastName = LastName; db.Contacts.InsertOnSubmit(contact); db.SubmitChanges(); } } I wanted to attach a Save method to the class so that I could call it on each object. When I introduced the above statement which contains ContactDataContext, I got the following error "In assembly ... PublicKeyToken=null' is not marked as serializable" It's clear that the DataContext class is generated by the framework (). I checked and did not see where that class was marked serialize. What can I do to overcome that? What's the rule when I'm not the author of a class? Just go ahead and mark the DataContext class as serializable, and pretend that everything will work? Thanks for helping

  • Removing elements using XSLT 1.0

    - by pmdarrow
    I'm attempting to remove Component elements from the XML below that have File children with the extension "config." I've managed to do this part, but I also need to remove the matching ComponentRef elements that have the same IDs as these Components. <Fragment> <DirectoryRef Id="MyWebsite"> <Component Id="Comp1"> <File Source="Web.config" /> </Component> <Component Id="Comp2"> <File Source="Default.aspx" /> </Component> </DirectoryRef> </Fragment> <Fragment> <ComponentGroup Id="MyWebsite"> <ComponentRef Id="Comp1" /> <ComponentRef Id="Comp2" /> </ComponentGroup> </Fragment> Based on other SO answers, I've come up with the following XSLT to remove these Component elements: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes" /> <xsl:template match="Component[File[substring(@Source, string-length(@Source)- string-length('config') + 1) = 'config']]" /> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> Unfortunately, this doesn't remove the matching ComponentRef elements. The XSLT will remove the component with the Id "Comp1" but not the ComponentRef with Id "Comp1". How do I achieve this using XSLT 1.0?

  • CustomProfile is not saving?

    - by Xaisoft
    I created a class that extends ProfileBase: public class CustomerProfile : ProfileBase { public int CustomerID { get; set; } public string CustomerName { get; set; } public static CustomerProfile GetProfile() { return Create(Membership.GetUser().UserName) as CustomerProfile; } public static CustomerProfile GetProfile(string userName) { return Create(userName) as CustomerProfile; } } If I do: CustomerProfile p = CustomerProfile.GetProfile(); p.CustomerID = 1; p.Save(); The next time I try to access the value for the current user, it is not 1, it is 0, so it appears it is not saving it in the database. In my web.config file I have the following snippet: <profile inherits="PortalBLL.CustomerProfile"> <providers> <add name="CustomerProfile" type="System.Web.Profile.SqlProfileProvider" applicationName="/" connectionStringName="LocalSqlServer"/> </providers> </profile> I tried the following and it worked, I am curious why it doesn't save it using the automatic properties. [SettingsAllowAnonymous(false)] public int CustomerID { get { return (int)base.GetPropertyValue("CustomerID");} set { base.SetPropertyValue("CustomerID",value);} }

  • iPhone/iPad : Check for invalid characters in a textbox made for Integers only

    - by JustinXXVII
    I noticed that the iPhone OS is pretty good about picking out Integer values when asked to. Specifically, if you use NSString *stringName = @"6("; int number = [stringName intValue]; the iPhone OS will pick out the 6 and turn the variable number into 6. However, in more complex mistypes, this also makes the int variable 6: NSString *stringName = @"6(5"; int number = [stringName intValue]; The iPhone OS misses the other digit, when what could have possibly been the user trying to enter the number 65, the OS only gets the number 6 out of it. I need a solution to check a string for invalid characters and return NO if there is anything other than an unsigned integer in a textbox. This is for iPad, and currently there is no numeric keyboard like the iPhone has, and I'm instead limited to the standard 123 keyboard. I was thinking that I need to use NSRange and somehow loop through the entire string in the textbox, and checking to see if the current character in the iteration is a number. I'm lost as far as that goes. I can think of testing it against zero, but zero is a valid integer. Can anyone help?

  • Exporting dataset to Excel file with multiple sheets in ASP.NET

    - by engg
    In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server. I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0. It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools. If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used. Please help. Thank you.

  • ASP.NET MVC: How do I validate a model wrapped in a ViewModel?

    - by Deniz Dogan
    For the login page of my website I would like to list the latest news for my site and also display a few fields to let the user log in. So I figured I should make a login view model - I call this LoginVM. LoginVM contains a Login model for the login fields and a List<NewsItem> for the news listing. This is the Login model: public class Login { [Required(ErrorMessage="Enter a username.")] [DisplayName("Username")] public string Username { get; set; } [Required(ErrorMessage="Enter a password.")] [DataType(DataType.Password)] [DisplayName("Password")] public string Password { get; set; } } This is the LoginVM view model: public class LoginVM { public Login login { get; set; } public List<NewsItem> newsItems { get; set; } } This is where I get stuck. In my login controller, I get passed a LoginVM. [HttpPost] public ActionResult Login(LoginVM model, FormCollection form) { if (ModelState.IsValid) { // What? In the code I'm checking whether ModelState is valid and this would work fine if the view model was actually the Login model, but now it's LoginVM which has no validation attributes at all. How do I make LoginVM "traverse" through its members to validate them all? Am I doing something fundamentally wrong using ModelState in this manner?

  • vb.net documentation and exception question

    - by dcp
    Let's say I have this sub in vb.net: ''' <summary> ''' Validates that <paramref name="value"/> is not <c>null</c>. ''' </summary> ''' ''' <param name="value">The object to validate.</param> ''' ''' <param name="name">The variable name of the object.</param> ''' ''' <exception cref="ArgumentNullException">If <paramref name="value"/> is <c>null</c>.</exception> Sub ValidateNotNull(ByVal value As Object, ByVal name As String) If value Is Nothing Then Throw New ArgumentNullException(name, String.Format("{0} cannot be null.", name)) End If End Sub My question is, is it proper to call this ValidateNotNull (which is what I would call it in C#) or should I stick with VB terminology and call it ValidateNotNothing instead? Also, in my exception, is it proper to say "cannot be null", or would it be better to say "cannot be Nothing"? I sort of like the way I have it, but since this is VB, maybe I should use Nothing. But since the exception itself is called ArgumentNullException, it feels weird to make the message say "cannot be Nothing". Anyway, I guess it's pretty nitkpicky, just wondered what you folks thought.

  • Geolocation and jQuery - Can't post results using ajax

    - by etombaugh
    I'm currently working on a project to make a location-aware site. In essence, the user comes to the page, and their location is found using the HTML5 method and then using jQuery, the location is posted to a page which saves the location/address to a codeigniter session, but if they want to update their location, or change to a different location(IE they want to use their work address as the location instead of their present address), theres a jQuery colorbox that displays and lets them type in a custom address. Everything works flawlessly to get the initial location, but when I try and get the updated location saved, I receive the error "Uncaught TypeError: Object [object DOMWindow] has no method 'lat'" which then Google Chrome references as being an error not in jQuery, but in the file for Google Maps API. Any suggestions? jQuery('.inputsubmit').click(function() { //Takes values from user submitted fields and parses them into an address string var street = jQuery('.inputaddress').val(); var city = jQuery('.inputcity').val(); var state = jQuery('.inputstate').val(); var address = street +" "+ city +", " +state; geocoder = new google.maps.Geocoder(); var geocoderresult= geocoder.geocode({'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var newlocation = results[0].geometry.location; //Posts coordinates and address string to a CodeIgniter function to update users session information jQuery.post("somepage", {location: newlocation, address: address},function(data) { alert("Data Loaded: " + data); }); } else { alert("Geocoder failed due to: " + status); } }); }); I've tried everything I can think of to get the post to work. All of the code works up till the point, and I've commented out the post line and everything works correctly. This is one of our main website's features, to provide instant and quick results based off of location. Thanks!

  • Help with java executors: wait for task termination.

    - by Raffo
    I need to submit a number of task and then wait for them until all results are available. Each of them adds a String to a Vector (that is synchronized by default). Then I need to start a new task for each result in the Vector but I need to do this only when all the previous tasks have stopped doing their job. I want to use Java Executor, in particular I tried using Executors.newFixedThreadPool(100) in order to use a fixed number of thread (I have a variable number of task that can be 10 or 500) but I'm new with executors and I don't know how to wait for task termination. This is something like a pseudocode of what my program needs to do: EecutorService e = Executors.newFixedThreadPool(100); while(true){ /*do something*/ for(...){ <start task> } <wait for all task termination> for each String in result{ <start task> } <wait for all task termination> } I can't do a e.shutdown because I'm in a while(true) and I need to reuse the executorService... Can you help me? Can you suggest me a guide/book about java executors??

  • Getting coordinates when clicking anywhere on a MapView

    - by DixieFlatline
    I just cant get this working. I tried using the code below with onTouchEventand and it doesn't work. If i return true at the end of the method, i get the toast with the coordinates but can't move a map, and if i return false, i can move a map but cant display a toast after the user clicks on a map. If i get it right, the other onTap method is used only for clicking on a overlays. Has anybody figured this thiing out? public boolean onTouchEvent(MotionEvent arg0, MapView arg1) { //super.onTouchEvent(arg0); int akcija = arg0.getAction(); if(akcija == MotionEvent.ACTION_UP){ if(!premik) { Projection proj = mapView.getProjection(); GeoPoint loc = proj.fromPixels((int)arg0.getX(), (int)arg0.getY()); String sirina=Double.toString(loc.getLongitudeE6()/1000000); String dolzina=Double.toString(loc.getLatitudeE6()/1000000); Toast toast = Toast.makeText(getApplicationContext(), "Širina: "+sirina+" Dolzina: "+dolzina, Toast.LENGTH_LONG); toast.show(); } } else if (akcija == MotionEvent.ACTION_DOWN){ premik= false; } else if (akcija== MotionEvent.ACTION_MOVE){ premik = true; } return false; //return super.onTouchEvent(arg0); }

  • How to make UISlider output nice rounded numbers exponentially?

    - by RickiG
    Hi I am implementing a UISlider a user can manipulate to set a distance. I have never used the CocoaTouch UISlider, but have used other frameworks sliders, usually there is a variable for setting the "step" and other "helper" properties. The documentation for the UISlider deals only with a max and min value, and the output is always a 6 decimal float with a linear relation to the position of the "slider nob". I guess I will have to implement the desired functionality step by step. To the user, the min/max values range from 10 m to 999 Km, I am trying to implement this in an exponential way, that will feel natural to the user. I.e. the user experiences a feeling of control over the values, big or small. Also that the "output" has reasonable values. Values like 10m 200m 2.5km 150 km etc. instead of 1.2342356 m or 108.93837756 km. I would like for the step size to increase by 10m for the first 200m, then maybe by 50m up to 500m, then when passing the 1000 m value, it starts to deal with Kilometers, so then it is step size = 1 km up until 50 km, then maybe 25 km steps etc. Any way I go about this I end up doing a lot of rounding and a lot of calculations wrapped in a forrest of if statements and NSString/Number conversions, each time the user moves the slider just a little. I was hoping someone could lend me a bit of inspiration/math help or make me aware of a more lean approach to solving this problem. My last idea is to populate and array with a 100 string values, then have the slider int value correspond to a string, this is not very flexible, but doable. Thank you in advance for any help given:)

  • 2 Mutually exclusive RadioButton "Lists"

    - by user72603
    I think this has to be THE most frustrating thing I've ever done in web forms. Yet one would think it would be the easiest of all things in the world to do. That is this: I need 2 separate lists of radiobuttons on my .aspx page. One set allows a customer to select an option. The other set does also but for a different purpose. But only one set can have a selected radiobutton. Ok I've tried this using 2 asp.net Radiobuttonlists controls on the same page. Got around the nasty bug with GroupName (asp.net assigns the control's uniqueID which prevents the groupname from ever working because now, 2 radiobuttonlists can't have the same groupname for all their radiobuttons because each radiobuttonlist has a different uniqueID thus the bug assigns the unique ID as the name attribute when the buttons are rendered. since the name sets are different, they are not mutually exclusive). Anyway, so I created that custom RadioButtonListcontrol and fixed that groupname problem. But when ended up happening is when I went to put 2 instances of my new custom radiobuttonlist control on my .aspx page, all was swell until I noticed that every time I checked for radiobuttonlist1.SelectedValue or radiobuttonlist2.SelectedValue (did not matter which I was checking) the value always spit back string.empty and i was not able to figure out why (see http://forums.asp.net/t/1401117.aspx). Ok onto the third try tonight and into the break of dawn (no sleep). I tried to instead just scrap trying to use 2 custom radiobuttonlists altogether because of that string.empty issue and try to spit out 2 sets of radiobuttonlists via using 2 asp.net repeaters and a standard input HTML tag inside. Got that working. Ok but the 2 lists still are not mutually exclusive. I can select a value in the first set of radiobuttons from repeater1 and same goes for repeater2. I cannot for the life of me get the "sets" to be mutually exclusive sets of radiobuttons.
