Unable to select and/or move controls in WinForm designer - winforms

I am facing one issue in WinForm. I am unable to select and/or move the controls present in the Form in designer. I checked for LOCK property of all controls (including the Form) and none of them are locked.
What could be the issue here? Spent a lot time there. Can anyone please help me?
Thanks & Regards,

If the Infragistics controls are shown in the Component Tray, than there might be version differences. What you could try is to open the licenses.licx file and remove the content from there. Do you have an Infragistics controls installed on your machine? Are there any difference after setting the "Specific Version" property of the Infragistics assemblies to "false"?
Is this happening only in your existing project or the same behavior is reproducible in a new project as well?

How to add ALL components into Visual studio 2010's toolbox for WPF apps?

This is driving me crazy. I right clicked on the toolbox and selected all the components under WPF components tab and there are still components missing, such as LinearGradientBrush, RadialGradientBrush etc. Where are the missing components and where can I find their dlls?
This ain't a direct answer to your question but maybe this might help you : Why are you not writing them directly in the XAML rather than using the designer? You'll eventually end up having to write the attributes of it anyway

Strange Design Problems With Infragistics Controls

I'm working on an existing WinForms application and I am having some weird issues with Infragistics controls in a WinForms app.
When I open a form or usercontrol in the project that has Infragistics controls on it, it looks like
this http://sdrv.ms/S7gvmS
I cannot access any of the controls in the design surface. Clicking does nothing. And, all of the controls appear in the lower area.
So I created a new test solution and dropped some Infragisstics controls on and got this http://sdrv.ms/SRdo2y
Anyone know what's going on?
When I've run in to similar issues before it's tended to be a license or version problem, the Infragistics libraries contain code stopping them working at design-time if a valid license isn't installed. To resolve this, I'd first recommend deleting all of the *.licx files in your solution. These can be easily corrupted especially if you're using source control and should be regenerated correctly when you go in at design time. If that fails, then I'd try uninstalling and reinstalling Infragistics ensuring the version installed matches those of your projects' reference.
P.S. Realise this is far too late to help the original poster but hopefully will help people coming across similar issues in the future.
This happens when Visual Studio cannot find the Design assembly. The components refer to a designer and if Visual Studio cannot find the designer, it makes the assumption that the object is a component instead of a control and places it in the system tray.
Typically, this indicates that something when wrong with your installation of the components, so the usual solution is to re-install.

DevExpress PivotGrid (Silverlight) : Popup Menus don't popup

We are using DevExpress Silverlight PivotGrid (11.2.7). The problem is that none of the popups work as one would expect.
Here is the xaml code (note that all of these properties are True by default and don't need to be set)
<dxpg:PivotGridControl
x:Name="pivotGrid"
... data bindings ...
IsFieldValuePopupMenuEnabled="True"
IsHeaderMenuEnabled="True"
IsHeaderAreaMenuEnabled="True"
/>
Once the host control for the grid is shown and the data is loaded right-clicking on any of the relevant areas doesn't bring either of the popups (there are 3).
Strangely (or not so strangely) in the sample SL project provided by devex everything works as it should.
The one (significant) difference between the sample app and our project is that we are using MEF and relevant .xaps are loaded dynamically based on which user logged in and some other stuff.
We have tried a lot stuff to figure out what is wrong but haven't managed to find anything even remotely relevant. Here is what we have tried :
Adding the pivotgrid to the host tabpage in codebehind after imports have been satisfied;
Setting / resetting properties mentioned above after imports from codebehind;
Adding the control to the startup page of the project before the MEF madness kicks in;
We also tried to popup the menus manually by inheriting from the pivotgrid control, but that has not yielded much;
Enabled RedrawRegions to make sure the popup is not popping 'under'. It's not;
Any pointers or ideas would be greatly appreciated.
Regards,
Alex
It appears that this was some bug in the version we were using at the time.
After updating to 12.1 everything works like it should without any tinkering from our side.
Looks like devex guys have bugs too...who knew right :)

Unable to drag and drop telerik components on windows forms

I am trying to drag and drop Telerik RadGridView on my windows form. But instead of showing on the form(in designer view), it shows the control just below the designer i.e. the area where some of the controls like DataSet, Binding Source, FileDialog controls are shown when added to the form from the toolbox.
The same problem happens for any rad control like RadButton, RadLabel etc. I can work on the control by using the controls added to the form, but the problem is that in case of some controls like RadGridView, the smart tag is not available that makes a lot of things easier.
I think I am missing something, so that I am unable to drag-drop the controls. Can any one help me out?
Can also be caused by a version mismatch. I had the latest version installed but code base referenced previous version (specifically 2011 Q2).
An uninstall of latest and install of 20011.Q2 fixed it for me.
This is caused by missing design time assembly in your GAC. Uninstall the all telerik controls from your computer, reinstall them and then update your project references. This should solve the problem.
More info at this link.
you must ReInstall your telerik product then open your project and reload your toolbox.
this sometime happen like you update your visual studio or you install a new package of telerik.

Re: Expander control in silverlight 4

I have installed the latest silverlight toolkit and dragged the expander control onto my design, there is some kind of an error going around with the name spaces, and my intellisense stopped to work after I added the control, following is the xmlns that is added to the application when I dragged the control onto the xaml editor:
xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit"
Can anyone please identify why would this happen?
Thanks
It's been a long time since you posted your question, but in the case you still have the problem, I tell you that I had it too and it was a conflict in versions. In Silverlight 4, controls of the toolkit are integrated to the framework. And your xmlns:toolkit should reference a dll, not a http uri.
My problem was I was using RC version of Blend. So I advise you to check your VS2010, Blend and Silverlight version to make sure they're aligned.
bye
