  • Why don't the .net 4.0 charting controls work in Visual Web Developer 2010 Express?

    - by kc
    The .net charting controls are now built into .net 4.0. They work great in Visual Studio 2010. However, they do not work in Visual Web Developer 2010 Express (which is what I have at home.) I get the error, System.Web.HttpException: Error executing child request for ChartImg.axd. That sounds like the message from .net 3.5 if charting wasn't set up correctly. But the bottom of the same page says, "Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1" Does anyone know why this doesn't work?

  • ASP.Net GridView UpdatePanel Paging Gives Error On Second Click

    - by joe
    I'm trying to implement a GridView with paging inside a UpdatePanel. Everything works great when I do my first click. The paging kicks in and the next set of data is loaded quickly. However, when I then try to click a link for another page of data, I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12030 aspx code <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <contenttemplate> <asp:GridView ID="GridView1" runat="server" CellPadding="2" AllowPaging="true" AllowSorting="true" PageSize="20" OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_PageSorting" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="ActivityLogID" HeaderText="Activity Log ID" SortExpression="ActivityLogID" /> <asp:BoundField DataField="ActivityDate" HeaderText="Activity Date" SortExpression="ActivityDate" /> <asp:BoundField DataField="ntUserID" HeaderText="NTUserID" SortExpression="ntUserID" /> <asp:BoundField DataField="ActivityStatus" HeaderText="Activity Status" SortExpression="ActivityStatus" /> </Columns> </asp:GridView> </contenttemplate> </asp:UpdatePanel> code behind private void bindGridView(string sortExp, string sortDir) { SqlCommand mySqlCommand = new SqlCommand(sSQL, mySQLconnection); SqlDataAdapter mySqlAdapter = new SqlDataAdapter(mySqlCommand); mySqlAdapter.Fill(dtDataTable); DataView myDataView = new DataView(); myDataView = dt.DefaultView; if (sortExp != string.Empty) { myDataView.Sort = string.Format("{0} {1}", sortExp, sortDir); } GridView1.DataSource = myDataView; GridView1.DataBind(); if (mySQLconnection.State == ConnectionState.Open) { mySQLconnection.Close(); } } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; bindGridView(); } protected void GridView1_PageSorting(object sender, GridViewSortEventArgs e) { bindGridView(e.SortExpression, sortOrder); } any clues on what is causing the error on the second click?

  • Convert Unicode char to closest (most similar) char in ASCII (.net)

    - by Andrey
    Hi all! Do you have any idea how to covert different Unicode characters to their closest ASCII equivalents? Like Ä - A. A googled but didn't find any suitable solution. Trick Encoding.ASCII.GetBytes("Ä")[0] didn't work. (Result was ?). I found that there is class Encoder that has Fallback property that is exactly for cases when char can't be converted, but implementations (EncoderReplacementFallback) are stupid and convert to ?. Any ideas? Thanks, Andrey

  • .Net - using FileIOPermission with mask in file name

    - by Max Gontar
    Hello! I would like to apply FileIOPermission on set of files using mask in file name, ex. on all txt files in folder C:\TMP: [type: FileIOPermission(SecurityAction.PermitOnly, Read = @"C:\TMP\*.txt")] class SomeClass { static void testPermissions() { Console.WriteLine("allowed action"); File.OpenRead(@"C:\TMP\1.txt"); // <--- here goes exception Console.WriteLine("denied action"); try { File.Create(@"C:\TMP\2.txt"); } catch (Exception e) { Console.WriteLine(e.Message); } finally { Console.ReadKey(); } } } This throws ArgumentException "Illegal characters in path." What is wrong? Is it possible to achieve anyway?

  • ASP.Net MVC Object Reference in Edit View when using DropDownListFor()

    - by hermiod
    This question is related to another I ask recently, it can be found here for some background information. Here is the code in the Edit ActionResult: public virtual ActionResult Edit(int id) { ///Set data for DropDownLists. ViewData["MethodList"] = tr.ListMethods(); ViewData["GenderList"] = tr.ListGenders(); ViewData["FocusAreaList"] = tr.ListFocusAreas(); ViewData["SiteList"] = tr.ListSites(); ViewData["TypeList"] = tr.ListTalkbackTypes(); ViewData["CategoryList"] = tr.ListCategories(); return View(tr.GetTalkback(id)); } I add lists to the ViewData to use in the dropdownlists, these are all IEnumerable and are all returning values. GetTalkback() returns an Entity framework object of type Talkback which is generated from the Talkback table. The DropDownListFor code is: <%: Html.DropDownListFor(model=>model.method_id,new SelectList(ViewData["MethodList"] as IEnumerable<SelectListItem>,"Value","Text",Model.method_id)) %> The record I am viewing has values in all fields. When I click submit on the View, I get an Object reference not set to an instance of an object. error on the above line. There are a number of standard fields in the form prior to this, so the error is only occurring on dropdown lists, and it is occurring on all of them. Any ideas? This is my first foray in to MVC, C#, and Entity so I am completely lost!

  • Add ASP.NET web service while impersonating credentials.

    - by George
    I have a web reference that I do not have access to through my windows credentials, but do through impersonation. Unfortunately, I cannot update or add the reference because of my lack of credentials. When the service is added, it works fine when I set impersonation to true and add credentials. Is there a way to impersonate a credentials when adding/updating a web service reference through the GUI?

  • asp.net mvc json result format

Thanks in advance!

  • asp.net with jquery valduation issue

    - by Eyla
    Greetings, I have 2 textboxs, 2 checkboxs and 2 labels. first textbox, checkbox, and label related to each other and the same for the rest. textbox should accept valid phone number based on jquery validation plugin and when the chackbox check the validation rule would change and in both option the error message would disply inside the label. I have no problem to implement that for one text box but when I add second one will have a problem and only the validation will happen for the second one only. please look at my code and advice. <script src="js/jquery-1.4.1.js" type="text/javascript"></script> <script src="js/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript"> var RegularExpression; var USAPhone = /^[01]?[- .]?(\([2-9]\d{2}\)|[2-9]\d{2})[- .]?\d{3}[- .]?\d{4}$/; var InterPhone = /^\d{9,12}$/; var errmsg; function ValidPhoneHome(sender) { if (sender.checked == true) { RegularExpression = InterPhone; errmsg = "Enter 9 to 12 numbers as international number"; } else { RegularExpression = USAPhone; errmsg = "Enter a valid number"; } jQuery.validator.addMethod("phonehome", function(value, element) { return this.optional(element) || RegularExpression.test(value); }, errmsg); } function ValidMobileHome(sender) { if (sender.checked == true) { RegularExpression = InterPhone; errmsg = "Enter 9 to 12 numbers as international number"; } else { RegularExpression = USAPhone; errmsg = "Enter a valid number"; } jQuery.validator.addMethod("mobilephone", function(value, element) { return this.optional(element) || RegularExpression.test(value); }, errmsg); } $(document).ready(function() { ValidPhoneHome("#<%= chkIntphoneHome%>"); ValidMobileHome("#<%= chkIntMobileHome%>"); $("#aspnetForm").validate({ rules: { "<%=txtHomePhone.UniqueID %>": { phonehome: true } } , errorLabelContainer: "#lblHomePhone", rules: { "<%=txtMobileHome.UniqueID %>": { mobilephone: true } } , errorLabelContainer: "#lblMobileHome" }) </script> <asp:CheckBox ID="chkIntphoneHome" runat="server" Text="Internation Code" onclick="ValidPhoneHome(this)" > <asp:TextBox ID="txtHomePhone" runat="server" ></asp:TextBox> <label id="lblHomePhone"></label> <asp:CheckBox ID="chkIntMobileHome" runat="server" Text="Internation Code" onclick="ValidMobileHome(this)" /> <asp:TextBox ID="txtMobileHome" runat="server"></asp:TextBox> <label id="lblMobileHome"></label>

  • Unit Testing - Validation of ViewModel ASP.NET MVC 2

    - by dean nolan
    I am currently unit testing a service that adds users to a repository. I am using dependency injection to test using a fake repository. The repository has a method CreateUser(User user) which just adds it to the database or in this case a List of Users. The logic for the creation is in the UserServices class. The application has a form for creating a user that requires some properties such as name and address. This is an MVC 2 app and I will be using the new validation using data annotations. This makes me wonder about a few things: 1) Should I annotate a POCO object that will map to the database? Or should I create a specific View Model that has these annotations and pass this data to the UserServices class? 2)Should the UserServicesClass also check this data? Would I best be constructing a Usr out of the ViewModel and passing this into the Service as a parameter? 3) The actual unit testing would depend on 2), I either populate a User object and pass that in, or I pass a large list of strings to the method CreateUser. Writing this out I get a basic idea that I should probably annotate the view model only, pass in a user (constructed by the view model if the data is valid) and also just construct the user in the unit test also. Is this the best way to go?

I have a object defined as: public class FullListObject : System.Collections.ArrayList, IPagedCollection And when i try to: IPagedCollection pagedCollection = (IPagedCollection)value; It don't work... value is a FullListObject... this is my new code trying to get around a issue with the "is" operator. When the system tests (value is IPagedCollection) it never gets true for FullListObject. How to cast the object to another object with a interface type?

  • Implementing a pager for asp.net's DataList/Repeater

    - by emre
    I have a DataList showing the results, and a Repeater that is supposed to be the pager. I decided to use the page number by redirecting with a QueryString parameter, so it will also be bookmarkable ... My problem is mainly in the UI actually. If I put DIV's with their onclick calling a JS function that does window.location = url + pagenumber , then somehow I have to deal with QueryString operations via JS which is a bit messy. If I use LinkButton objects within the ItemTemplate, then the Redirecting happens only when the linkbutton is clicked while whole div has cursor: pointer , you what I mean. What would be the best approach to this? Thanks in advance. Note: I really want to spend the time and effort implementing my own server-side paging. I think its more fun than reading 3rd party manuals.

  • Aletrnatives to MultiView in ASP.NET

    - by remdao
    Hi The website I'm building contains a large number of views which will be displayed on the same place but hidden or shown according to how the user navigates the menu. It gets quite messy in visual studios design view when you have a MultiView with 10 different views in it. I've already separated the content of each view in several user controls. But is there an alternative to MultiView?

  • ASP.NET 2.0: Specifying an instance of an object for an ObjectDataSource

    - by Austin Salonen
    I'm using an ObjectDataSource to bind data to a GridView; it works fine except that it always creates a new object to use as a data source. I can do all the setup just fine but I cannot use an instance of an existing object to specify as the "data source" for it. Is it possible to do this? If so, how? If it's not possible, why? EDIT: Here's the gist of what's going on (object types changed): On the first page you are editting the attributes for a dog. One of the attributes is "has puppies" and if it's true, the next page you specify the names of those puppies. What's happening in my case is that those puppies are not getting linked to the original dog but to a "new" dog. (The implication that my problem is a "female dog" was coincidental. ;-) )

  • Append XML string block WITH NAMESPACE REF to existing XmlDocument in .NET

    - by FT
    I have an xml document (XmlDocument) which looks like this... <stuff xmlns:n="hhtp://tempuri.com/"> </stuff> ... and a "fragment" (string) which looks like this <things> <thing n:type="info"> </thing> </things> I want to "inject" the fragment into the main document. How? (HINT: You can't use XmlDocumentFragment because the namespace 'n' isn't declared in the fragment, and the object model complains about this - throwing an 'unknown namespace' error even though the resultant document will be perfectly valid.)
