[Solved] Error #4004 after upgrading to Silverlight 3 Controls...

[mark baer]

I upgraded my development machine to Silverlight 3 and I installed the new Telerik Controls for SL 3.  When I try to run my project, when I bind data to a RadGrid, I get the Sys.InvalidOperationException ManagedRuntimeError error #4004.  It points the line in the xaml where my radgrid resigns.  Here is my RadGrid xaml:

<

 

telerik:RadGridView Name="radGridSoundDetails" >

 

 

 

<telerik:RadGridView.Columns>

 

 

 

<telerik:GridViewDataColumn HeaderText="Track #" Width="75" DataMemberBinding = "{Binding TrackNumber}"></telerik:GridViewDataColumn>

 

 

 

<telerik:GridViewDataColumn HeaderText="Source Roll" Width="100" DataMemberBinding = "{Binding SourceItemId}"></telerik:GridViewDataColumn>

 

 

 

<telerik:GridViewDataColumn HeaderText="Track Type" Width="300" DataMemberBinding = "{Binding TrackType}" ></telerik:GridViewDataColumn>

 

 

 

<telerik:GridViewDataColumn HeaderText="Language" Width="175" DataMemberBinding = "{Binding Language}" ></telerik:GridViewDataColumn>

 

 

 

</telerik:RadGridView.Columns>

 

 

 

</telerik:RadGridView>

Here are my radgrid dll properties:  Telerik.Windows.Controls.GridView(2009.2.701.1020)

Help?  When I upgraded, I uninstalled SL2 SDK, SL 2 Tools and Telerik Controls for SL2.  Then I installed SL3 Tools for VS 2008, and the Telerik Controls for SL3.

Thanks

I found it.  I had somehow inadvertantly typed some text in the middle of a Column Definition like this:

<telerikGridView

 

:GridBADTEXTViewDataColumn HeaderText="mark">

instead of:

<telerikGridView:GridViewDataColumn HeaderText="mark">

Took forever to find it.  The error code didn't point to this line in the xaml...That probably would have helped...Once I removed the grids and started adding them back, I noticed the syntax error...ugh...At least it's fixed.  Sorry to bother you guys with this one.
