Custom OperationDescription not added to the WsdlContractConversionContext

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :WCF
Hello, I have developed a custom IWsdlExportExtension in which I add a pseudo operation to the wsdl file:   // operationDescription has been initialized here context.Contract.Operations.Add(operationDescription); // add behaviors to the operationDescription, such as OperationBehaviorAttribute, DataContractSerializerOperationBehavior However if I open the WSDL file I get the following exception: System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior contract: http://tempuri.org/:IEntityService ----> System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at System.ServiceModel.Description.MessageContractExporter.GetMessageName(MessageDescription messageDescription) After I downloaded the WCF source code I found out that the problem is in the following call - GetOperation is the one that throws the KeyNotFoundException: Operation op = context.GetOperation(operationDescription); Now I would expect that after addition the operationDescription to context.Contract.Operations I can then retrieve the respective Operation from the context. However this is not the case. In WsdlContractConversionContext there is the AddOperation functions which adds the mapp

Keeping Custom properties in GridView Added on OnRowDataBound Event While Sorting

All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView. How I can keep my custom styles on sorting that I added during OnRowDataBound event.   Thanks for your help.

Why would a control not respond to mouse clicks when added to a custom canvas


   I have a custom UserControl that contains a grid and toolbar.  When I add this control to a custom drag canvas, it does not respond to MouseClick events.
   I suspected the custom drag panel as it overrides UIElement.OnPreviewMouseLeftButtonDown and sets e.Handled = true but commenting out line that sets e.Handled to true does not allow control process mouse clicks.
   If, however, I derive my custom control from Popup, it sees mouse clicks as toolbar button commands are executed. 
   What am I observing?

When using a custom theme, there is no custom files added to "_themes" directory.


I've been working on customizing some Sharepoint 2010 Team sites and have read through many helpful articles on how to create and edit custom themes. The most consistent method is to create a base theme in Powerpoint which I've done.

I then install this THMX file in the themes library and apply it to my pages which seems to work as expected. The one inconsistency with what these articles say and what is happening on my end is that there is no numbered directory created in the "_themes" directory when I view All Files. These articles explain that this directory is created every time you apply a theme to your site so you can further edit the images and CSS associated with the theme. All I see in this "_themes" directory is "Custom.thmx, CustomPreview.thxm."

Is there some site setting or permissions issue I should look into to have this directory available to me?


Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Write Custom WebParts for SharePoint 2007

The popularity of SharePoint Portal Server 2003 led Microsoft to tightly integrate the next SharePoint version, Microsoft Office SharePoint Server (MOSS) 2007, with its ASP.NET 2.0 WebPart framework. This tight integration enables the ASP.NET and SharePoint developer to do a number of things that previously weren't possible

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

How to implement custom HttpContext for each request under class that implements IHTTPHandler


Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If

Custom Control Design-Time SiteMap Provider Error


Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.
