  • ServerControl randomly null

    - by Sascha
    Hi, I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment. Anyone an idea how to find more info to find what's happening? Or has someone had a similar error? Thanks. sa

  • Web based weekly planner

    - by Calum
    Hello I'm looking to implement a web based weekly planner where a user can set when they will be unavailable to work. The state of the week will be saved as a 'varbinary' with a length of 168 which will represent every hour of everyday of a week. The database only needs to store the value of one week as the times unavailable to work will be the same each week. I'm looking for a quick and effective method, possibly based on jquery. Thanks

  • how to include in web.config an external mydll.config file and read its values?

    - by firepol
    Hi, I found this answer about external configuration files. I'm trying to do a similar thing. I have a small webapplication called StatsGen I want to include in other projects, and for convenience I'd like to have the settings inside the bin folder, in a config file with an appropriate name, in my case: StatsGen.config. So I've put these line in the web.config (as explained in the answer I mentioned above): <configSections> <section name="StatsGenSettings" restartOnExternalChanges="true" type="System.Configuration.NameValueFileSectionHandler" /> <!--sectionGroups--> </configSections> <StatsGenSettings configSource="StatsGen.config"></StatsGenSettings> <!--and here comes the rest... appSettings etc.--> Inside the bin folder, I created a StatsGen.xml file, then renamed it to StatsGen.config. It looks like this: <?xml version="1.0" encoding="utf-8" ?> <StatsGenSettings> <add key="Password" value="myStatsPass" /> <add key="ConnectionString" value="Server=mydbsrv;Database=myDB;User ID=myUser;Password=myPass" /> </StatsGenSettings> I created an Helper class, as suggested in the answer. In the Page_Load of my default.aspx.cs file, I've put: goodPassword = StatsGenSettings.Instance["Password"]; When I load my page, I get this error: The type initializer for 'StatsGen.Helpers.StatsGenSettings' threw an exception. I've tried to exlude the helper and just to get access to the key, like this: NameValueCollection _settings = ConfigurationManager.GetSection("StatsGenSettings") as NameValueCollection; And I get this error: Unable to open configSource file 'StatsGen.config'. (C:\Users\pbo\Documents\Visual Studio 2010\Projects\StatsGen\StatsGen\web.config line 21) At line 21 I just have this, as explained above: <StatsGenSettings configSource="StatsGen.config"></StatsGenSettings> So now I'm wondering, what's wrong? Some detailed help would be cool... like: where exactly should I declare the StatsGenSettings element inside the web.config? It was not specified in the answer I've found... or what else am I doing wrong? Thanks for letting me know...

  • Arraylist as repeater datasource (how to access from .aspx)

    - by Phil
    I have an arraylist: Dim downloadsarray As New ArrayList downloadsarray.Add(iconlink) downloadsarray.Add(imgpath) downloadsarray.Add(filesize) downloadsarray.Add(description) Which is the datasource of my repeater: DownloadsRepeater.DataSource = downloadsarray DownloadsRepeater.DataBind() Please can you tell me how I output the items in the array to the .aspx page. I usually use (when using sqldatareader as datasource): <%#Container.DataItem("1stcolumnnamestring")%> <%#Container.DataItem("2ndcolumnnamestring")%> But this does not work when using the arraylist as datasource. Thanks. ps... I know how to use <%#Container.DataItem% to dump everything but I need to get at the items in the array individually, not have them all ditched out to the page in one go. For example, item 1 contains a link, item 2 contains an image path, item 3 contains a description. I need to have them kick out in the correct order to build the link and icon correctly.

  • Spring.NET & Immediacy CMS (or how to inject to server side controls without using PageHandlerFactor

    - by Simon Rice
    Is there any way to inject dependencies into an Immediacy CMS control using Spring.NET, ideally without having to use to ContextRegistry when initialising the control? Update, with my own answer The issue here is that Immediacy already has a handler defined in web.config that deals with all aspx pages, & so it's not possible add an entry for Spring.NET's PageHandlerFactory in web.config as per a normal webforms app. That rules out making the control implement ISupportsWebDependencyInjection. Furthermore, most of Immediacy's generated pages are aspx pages that don't physically exist on the drive. I have changed the title of the question to reflect this. What I have done to get Dependency Injection working is: Add the usual entries to web.config for Spring.NET as outlined in the documentation, except for the adding the entry to the <httpHandlers> section. In this case I've got my object definitions in Spring.config. Create the following abstract base class that will deal with all of the Dependency Injection work: DIControl.cs public abstract class DIControl : ImmediacyControl { protected virtual string DIName { get { return this.GetType().Name; } } protected override void OnInit(EventArgs e) { if (ContextRegistry.GetContext().GetObject(DIName, this.GetType()) != null) ContextRegistry.GetContext().ConfigureObject(this, DIName); base.OnInit(e); } } For non-immediacy controls, you can make this server side control inherit from Control or whatever subclass of that you like. For any control with which you wish to use with Spring.NET's Inversion of Control container, define it to inherit from DIControl & add the relelvant entry to Spring.config, for example: SampleControl.cs public class SampleControl : DIControl, INamingContainer { public string Text { get; set; } protected string InjectedText { get; set; } public SampleControl() : base() { Text = "Hello world"; } protected override void RenderContents(HtmlTextWriter output) { output.Write(string.Format("{0} {1}", Text, InjectedText)); } } Spring.config <objects xmlns="http://www.springframework.net"> <object id="SampleControl" type="MyProject.SampleControl, MyAssembly"> <property name="InjectedText" value="from Spring.NET" /> </object> </objects> You can optionally override DIName if you wish to name your entry in Spring.config differently from the name of your class. Provided everything's done correctly, you will have the control writing out "Hello world from Spring.NET!" when used in a page. This solution uses Spring.NET's ContextRegistry from within the control, but I would be surprised if there's no way around that for Immediacy at least since the page objects themselves aren't accessible. However, can this be improved at all from a Spring.NET perspective? Is there maybe an Immediacy plugin that already does this that I'm completely unaware of? Or is there an approach that does this in a more elegant way? I'm open to suggestions.

  • Silverlight or MVC for Web Development

    - by jhorback
    I was just wondering about the opinions out there. What do you think promotes faster development times for a web application? Silverlight or .Net MVC? And could Silverlight be a replacement for a true http web application? Feel free to rant or give as much details as necessary.

  • Why doesn't a URL Route with two dashes resolve?

    - by Atomiton
    I'm trying to resolve this URL Route: Route articlesByCategory = new Route("articles/c{cid}-{category}", new Handler); However, it seems like the following url won't resolve to this route: // doesn't work www.site.com/articles/c24-this-is-the-category-title // This works www.site.com/articles/c24-category I assume it has to do with the dashes in the title, but can anyone tell me why this works this way? Is there a way to allow dashes in the title for a URL route like this?

  • Databinding multiple tables linq query to gridview?

    - by Curtis White
    My question is how can I display a linq query in a gridview that has data from multiple tables AND allow the user to edit some of the fields or delete the data from a single table? I'd like to do this with either a linqdatasource or a linq query. I'm aware I can set the e.Result to the query on the selecting event. I've also been able to build a custom databound control for displaying the linq relations (parent.child). However, I'm not sure how I can make this work with delete? I'm thinking I may need to handle the delete event with custom code.

  • MVC validation error with strongly typed view

    - by Remnant
    I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

  • MVC3/Razor Client Validation Not firing

    - by Jason Gerstorff
    I am trying to get client validation working in MVC3 using data annotations. I have looked at similar posts including this MVC3 Client side validation not working for the answer. I'm using an EF data model. I created a partial class like this for my validations. [MetadataType(typeof(Post_Validation))] public partial class Post { } public class Post_Validation { [Required(ErrorMessage = "Title is required")] [StringLength(5, ErrorMessage = "Title may not be longer than 5 characters")] public string Title { get; set; } [Required(ErrorMessage = "Text is required")] [DataType(DataType.MultilineText)] public string Text { get; set; } [Required(ErrorMessage = "Publish Date is required")] [DataType(DataType.DateTime)] public DateTime PublishDate { get; set; } } My cshtml page includes the following. <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) Post <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Text) </div> <div class="editor-field"> @Html.EditorFor(model => model.Text) @Html.ValidationMessageFor(model => model.Text) Web Config: <appSettings> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> Layout: <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> So, the Multiline Text annotation works and creates a text area. But none of the validations work client side. I don't know what i might be missing. Any ideas?? i can post more information if needed. Thanks!

  • How to handle ThreadAbortException Without Specifying False for Response.End

    - by coffeeaddict
    I know all about this exception, read the msdn article here http://support.microsoft.com/kb/312629/EN-US/ but I do not know how to handle this when my boss does not want me to throw in false for the Response.End. Here's what I have: else { try { VoidlOrder(transactionID); } catch (Exception ex) { LogError(ex.ToString()); } finally { RedirectUser(sessionID,"showfmsg=1", true); } } RedirectUser is just a utility method we run that ultimately passes in true for the reponse.redirect resopnse.end param. So what other option is there other than putting false as this param? He's stating to catch it and do something...ok do what? I don't see any other fix than to send false into this call every time because I can't get pass this exception..I get it every time.

  • What is the way to go to fake my database layer in a unit test?

    - by Michel
    Hi, i have a question about unit testing. say i have a controller with one create method which puts a new customer in the database: //code a bit shortened public actionresult Create(Formcollection formcollection){ client c = nwe client(); c.Name = formcollection["name"]; ClientService.Save(c); { Clientservice would call a datalayer object and save it in the database. What i do now is create a database testscript and set my database in a know condition before testing. So when i test this method in the unit test, i know that there must be one more client in the database, and what it's name is. In short: ClientController cc = new ClientController(); cc.Create(new FormCollection (){name="John"}); //i know i had 10 clients before assert.areEqual(11, ClientService.GetNumberOfClients()); //the last inserted one is John assert.areEqual("John", ClientService.GetAllClients()[10].Name); So i've read that unit testing should not be hitting the database, i've setup an IOC for the database classes, but then what? I can create a fake database class, and make it do nothing. But then ofcourse my assertions will not work because if i say GetNumberOfClients() it will alwasy return X because it has no interaction with the fake database class used in the Create Method. I can also create a List of Clients in the fake database class, but as there will be two different instance created (one in the controller action and one in the unit test), they will have no interaction. What is the way to make this unit test work without a database?

  • Am I using handlers in the wrong way?

    - by superexsl
    Hey, I've never used HTTP Handlers before, and I've got one working, but I'm not sure if I'm actually using it properly. I have generated a string which will be saved as a CSV file. When the user clicks a button, I want the download dialog box to open so that the user can save the file. What I have works, but I keep reading about modifying the web.config file and I haven't had to do that. My Handler: private string _data; private string _title = "temp"; public void AddData(string data) { _data = data; } public bool IsReusable { get { return false; } } public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/csv"; context.Response.AddHeader("content-disposition", "filename=" + _title + ".csv"); context.Response.Write(_data); context.Response.Flush(); context.Response.Close(); } And this is from the page that allows the user to download: (on button click) string dataToConvert = "MYCSVDATA...."; csvHandler handler = new csvHandler(); handler.AddData(dataToConvert); handler.ProcessRequest(this.Context); This works fine, but no examples I've seen ever instantiate the handler and always seem to modify the web.config. Am I doing something wrong? Thanks

  • AuthenticationType Negotiate vs NTLM

    - by Claudio Redi
    I have the same code base used on 2 different sites hosted on the same server (IIS 7.5). For some reason, when I check the Identity.AuthenticationType property on the code behind of an http handler I see NTLM for 1 site and Negotiate for the other. This is causing some problems and I need both of them to use NTLM. Could you help me to figure out why this difference? So far I see both IIS sites are configured on the same way but of course there is at least 1 difference that I couldn't detect. Thanks!

  • Data Annotations on ViewModels or Domain Objects

    - by Ahmad
    Where would data annotations be more suitable: ViewModels or Domain Objects or Both I am struggling to decide where these will be more suited. I have not as yet fully utilized them but this question came to mind. From most of the examples I have seen, they are generally placed on Models and simply use the required attributes for validation using ModelState.IsValid. I have also seen another question on SO where the use of data annotations alone is not sufficient and advocate. Option 1 - I will still need to validate again in my service layer. ( I think that my service layer should be complete and this include validation, since its planned to be used elsewhere) Option 2 - How will I then get the benefits of the built in validation both client and server side. Option 3 - there will be a repetition of validation logic, however I was wondering if one could use a MetaData class approach that can be used for both ViewModels and Domain Objects. ( This is completely of the top of my head, so it may be nonsensical) I wonder if this question even makes sense. If not, can someone please help in understanding this better. Have I completely misunderstood the use of data annotations?

  • Perform Grouping of Resultset in Code

    - by NinjaBomb
    Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

  • How do I apply css for textboxes only but not for all the <input> types like CheckBoxes, etc.?

    - by George
    If all browsers supported attribute selectors, we could easily do the following: input[type='text'] { font:bold 0.8em 'courier new',courier,monospace; } input[type='radio'] { margin:0 20px; } input[type='checkbox'] { border:2px solid red; But I don't think all IE versions of ^ and greater support this. I think I'd like to avoid skins. Not sure why, other than I tried them and I recall having a negative experience. It was probably my lack of knowledge. Are there any issues in using and CSS, external or otherwise? What's the best way to handle this? Currently I am assigning separate classes to each control type.
