My user controls stopped working in Design mode! Why?

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :WPF

I have a few user controls that I have been using for months but now whenever I open a page in Blend that uses one of the controls I get an invalid xaml error. The project still compiles and runs and behaves just like it's supposed to but I can't edit xaml in Design view because of this error.


In the page I have

<local:ACAVariableWidth x:Name="CIDCloseButton" HorizontalAlignment="Right" Margin="0,0,17.54,15" VerticalAlignment="Bottom" Width="174" Height="89" MouseLeftButtonDown="callerID_close" Text="Close"/>

The error is: The member "Text" is not recognized or is not accessible

In the user control xaml I have:

		<StackPanel x:Name="TopSP" Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center" Height="76" d:IsLocked="True">
			<TextBlock x:Name="ACATB" Margin="8,8,8.5,9.5" FontFamily="APHont" FontSize="32" Padding="5,0" Foreground="White" TextAlignment="Center" VerticalAlignment="Center" Text="{Binding ElementName=UserControl, Path=Text}" d:IsLocked="True">
					<DropShadowEffect Direction=&

Usage Reports / Graphical User Statistics stopped working


Hi all,

our usage reports (e.g. at /_layouts/SpUsageSite.aspx ) stopped working after we migrated the database from one server to another. The "raw statistics" (_layouts/usagedetails.aspx), however, are still showing some numbers.

All services are still running, all relevant settings in Central Admin (SSP, Operations) are still active. Does anyone knoe what could be the cause for this?


Design mode is meshing all controls together


When I designed a particular page, it looked just fine and "normal" while in design mode in VWD Express 2010, but then I changed the CSS file to make the font large, and every time I go into the design mode for this page all of the text and controls are overlapping.  It makes it almost impossible to click anything, and it is just a bad visual representation of the page while in design mode.

Anybody have any idea why this may be happening?

Thanks in advance. :)

Working with DropDownList and ListBox Controls in ASP.NET

UI Datepicker and web user controls



I have developed an application using the Master-Detail pattern described in this Matt Berseth article.

The only difference between Matt's article and me is that I am using a FormView object in place of a DetailsView.

Everything works fine except that the formview object, in my case it's inside a user control and I can't figure out how to use the jquery datepicker UI plugin.

I have tried to put the script block for the datepicker either in the aspx page as well as inside the user control but in both cases the calendar does not come up when the related textbox get the focus.

Any suggestion on how to work with the datepicker inside an ascx?

thanks in advance!

Advanced Basics: Adding New Features with User Controls


In past versions of Visual Basic, there were rudimentary graphics controls. In Visual Basic .NET you have the GDI+ library, which enables you to draw lines, circles, and most anything else. But how can you use the functionality of GDI+ to create lines and other graphics that respond to user mouse clicks and events? Find out.

Visual Studio .NET: Building Windows Forms Controls and Components with Rich Design-Time Features, P


This is the second of two articles discussing the extremely rich design-time features of the .NET Framework. Part 1 discussed the basics, showing you where to start and how to extend your control implementation through attributes and interfaces, as well as their effects on the property browser, code serialization, and other controls. Part 2 continues the journey by concentrating on design-time functionality that you can implement beyond your components and controls, including TypeConverters, UITypeEditors, and Designers. It would be impossible to cover everything you can do in two short articles, which is a testament to just how all-encompassing and flexible the design-time capability of the .NET Framework is.

Visual Studio .NET: Building Windows Forms Controls and Components with Rich Design-Time Features


Visual Studio .NET provides support for designing rich features into your controls and components, allowing you to set properties, set form placement, inherit from base classes, and much more. So how does Visual Studio .NET do all this? What does the Windows Forms designer do? What's the difference between a control and a component? How does Visual Studio integrate your controls so that they can access features of the .NET Framework?In this article, the authors answer these common questions by building a clock control and taking the reader along for the ride. In building the control, hosts and containers are illustrated, the property browser is explained, debugging is discussed, and a general overview of the design-time infrastructure is presented.

Windows Forms: Developing Compelling User Controls that Target Forms in the .NET Framework


In the beginning, writing controls meant dealing with Windows messages. Then came Visual Basic controls, which introduced methods, properties, and events. Later, ActiveX controls, which ran atop COM, became popular. While each innovation in control writing brought more flexibility, nothing has matched the versatility of the new .NET Windows Forms controls and Web Forms controls. This article, the first of a two-part series, introduces the reader to Windows Forms, beginning with their inheritance from one of the .NET CLR base classes, which makes control creation much faster than before. Control programming is illustrated through the development of a login control. The equally flexible Web Forms controls will be covered in Part 2.

asynchronous loading user controls


I have 3 user controls that I have to load at the same time.  They each contain a gridview that pulls data from the database.  They are doing a "delay" load of the data so there is a progress bar template that shows that the data is loading however the first gridview fires and loads, then the second, then the third and I need them to all fire at the same time.  Any ideas? 

User Controls and Control Extenders


Two separate questions, but sufficiently intertwined that I'm going to try the two together....

Firstly - User Controls and Behaviours

I have a User Control which contains a few visual controls.  I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences.  That is all rock solid and working well.  However, when developing, I did discover that I couldn't attach the behaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control.  So, I have attached my behaviours to a "random" TextBox within the User Control. 

So - first question, is there a better way to do that?  For example, should I always be rendering a SPAN as an element to surround the control?  Not sure what that would do to the robustness of the rendering.  What is the right way to attach a behaviour to a User Control.

Secondly - Accessing those same Behaviours later

Assume I have placed a User Control on the page.  That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour).

Working with datepicker and input controls


Helloe all,

Please I'm developing a hotel reservation system and I have both "check in" and "check out" html "input"controls and I have linked these controls to the Jquery datepicker. Unfortunately, I'm not able to access the value of the controls in asp code behind (using their ids CheckInDate and CheckOutDate respectively).

Previously, I used asp textboxes and I was able to access the IDs in code behind but whenever the page displays and I click in any of the textboxes their respective datepicker don't show.

However, I'm able to access the html input controls in code behind when I add runat="server" but when I do that the datepicker don't show for both control when I click in the input boxes.

Someone help me so that I will be able to make the datepicker show as well as fetching/accessing the value of the input boxes (selected dates) in the code behind...... or how to use asp controls and add onclick functions to call the datepicker.

Thank you.


<script type="text/javascript">
        $(function() {       
        $("#CheckInDate").datepicker({ minDate: 0, maxDate: '+1M' });

WPF+ VS2010: Design mode error "The URI prefix is not recognized"?

our application uses VS2008 and WPF. To apply the styles in the design mode, we have used the "BlendMergedDictionary" class (see the following link) http://stackoverflow.com/questions/995101/how-do-i-get-wysiwyg-design-in-blend-vs-without-merged-resourcedictionary-in-ever It works very well in VS2008 IDE.
