XamlParseException: [Line: 0 Position: 0]" Issue

Hello,

Reading thought the details under the exception, it doesn't seem to be related to our controls. Would you please try clearing your solution and rebuilding it?

Hello Didie,

thank you for your response.

tried that so many times, CLean and rebuilt didn't resolve my issue :(. My app was working fine but when i converted all Silverlight control to Telerik, this issue appeared. i tried every solution that was suggested in different threads. Clean and Rebuilt succeed, actually its fine at runtime but i am not able to get design view.

Hello,

May I ask you to share more detailed information on your exact configuration you have and what controls do you use? Do you reference  full or NoXaml binaries? You can check our documentation on Implicit Styles for more information on the difference between both.

What Theme have you applied? What is the version of the referenced assemblies and which are they exactly? Would it be possible for you to isolate the case to a single control/assembly? Any additional information helping us to locate the problem will be also very useful.

Hello Didie,

I updated telerik to latest just before replying to you, but got no luck with issue. I am using Telerik's Label, RadTabControl, 7 RadGridView, RadComboBoxes, RadMaskedTextInput, RadMaskedNumericInput, RadExpander, RadButtons. I am using all above mentioned controls in a Silverlight ChildWindow along with some silverlight's Checkboxes.

Also one othe thing i wanna share with you is that when i comment out Telerik Labels the error changes to "ArgumentException: The value "Telerik.Windows.Controls.Animation.TreeViewExpandCollapseAnimation" is not of type "Telerik.Windows.Controls.Animation.RadAnimation" and cannot be used in this generic collection.
Parameter name: value" PLEASE SEE ATTACHMENTS FOR MORE DETAIL.

I am not able to fine that which control is producing the issue thats why i can not isolate the case in another project.

waiting for your response.

Hello Didie,

I have opened my project in Visual Studio 2010 and 2012, and its working fine. Is there any support issue with Telerik controls in Visual Studio 2013?

Hello Imdad,

I tried to reproduce the exception in Visual Studio 2013 but to no avail. The exception is thrown by RadTreeView collapse-expand animation but the latter is working as expected on our side.
I suggest that you went through every project in your solution that refers our binaries and delete the bin & obj folders (you have to close Visual Studio to be able to achieve this). Then open the IDE again and clean and rebuilt the solution. You should be able to see all controls without errors in Design View.

If you still reproduce the unwanted behaviour please send us a runnable version of your project so that we can reproduce and inspect it locally. Without any sample that reproduces this we are unable to help you.

Hi All in this thread,
Just to help anyone who experiences this in the future:
I upgraded my telerik controls using the upgrade wizard and I encountered exactly this same problem.  All of my pages with telerik controls were experiencing this problem with a XamlParseException at Line:0 Col:0.
The way to fix it was this:

1.  Remove all references to the telerik dlls.
2.  Re-add the references from the primary installation location (in my case C:\Program Files (x86)\Telerik...

If you do this while you have one of the offending pages open, you will see it instantly render correctly.
