FeatureDataGrid not compile.

[GeneLiu]

I have copied a sample from http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataGrid.
I have included all the GIS related references:
ESRI.ArcGIS.Client
ESRI.ArcGIS.Client.Behaviors
ESRI.ArcGIS.Client.Bing
ESRI.ArcGIS.Client.Toolkit
ESRI.ArcGIS.Client.Toolkit.DataSources
ESRI.ArcGIS.Client.WebMap

I also include the window related references:
System.Windows.Controls
System.Windows.Controls.Data
System.Windows.Controls.Data.Input


I cannot compile it. The error is:
Error 1 The type or namespace name 'FeatureDataGrid' could not be found (are you missing a using directive or an assembly reference?) ~\samples\toolkit controls\featuredatagrid\MuellerFeatureDataGrid\MuellerFeatureDataGrid\obj\Debug\MainPage.g.i.cs 40

Please help,
Thanks a lot.

Might be a mismatch in your referenced ESRI dlls.

Double check the version of the dlls that your project references.
Clean your solution.
Exit visual studio.
Remove bin and obj directory.
Try again. Hopefully that's enough:)

Thank you very much!
I did everything you suggested. I get the same compile error.
Here is the dll info I am reference to:
ESRI.ArcGIS.Client
ESRI.ArcGIS.Client.Behaviors
ESRI.ArcGIS.Client.Bing
ESRI.ArcGIS.Client.Toolkit
ESRI.ArcGIS.Client.Toolkit.DataSources
ESRI.ArcGIS.Client.WebMap

File version: 2.4.0.851
Product version: 2.4.0.851
Date modified: 1/10/2012

Are they a wrong version of DLLs?

Here are some more info about this.
If I remove the <esri:FeatureDataGrid ... variable from mainpage.xaml and define a local variable mainpage.xaml.cs,
such as,
            FeatureDataGrid fdg = new FeatureDataGrid()
            {
                //bindings ...
            }
I can pass compile. Does this mean the version of the DLLs is ok?

Please help,
Thanks a lot.

I found out this problem - FeatureDataGrid not working for Silverlight 5.

Thanks,

Hello,

Our 2.4 version is targeted at SL4. SL5 microsoft changed the version numbers on System.Windows.Data.dll which requires the FeatureDataGrid reference the new assembly. If you want to build for SL5 our latest release v3.0 Pre-Release was built and released for SL5.
