The type 'DataRowView' does not contain a public property named 'UnitColumn'

[Rob]

Hello,
I am running into the error: "The type 'DataRowView' does not contain a public property named 'UnitColumn'" error when trying to edit a cell in the radGridView cell.  I am dynamically creating a DataTable to bind to.  I have copied the xaml, along with the codebehind for a small sample that illustrates the issue. 
Thanks for your help!

Rob

Hello,

 Can you post a bit more info where exactly you get this? Please post also the grid version. 

All the best,

Hi Vlad,

The error occurs when I edit a cell:
1) Double-Click on a cell
2) Enter a value (that is consistent with the data type)
3) Exit the cell

The version of Telerik.Windows.Controls.GridView is: 2010.2.924.40.

Thanks!

Hi,

 Can you try our latest official version (Q3 2010 SP1) instead?

Is there a confirmed bug in the version I am working with?  The reason I ask is that I am working on a large project with many players.  There will be a cost associated with changing the component.

Hello Rob,

We can confirm that we had this issue in Q2 2010 SP2 (version .0924). It was fixed in the first internal build after SP2 was released. The internal build version is .1001. 

Please, excuse us for the inconvenience caused.

How do we get access to that build?  We have a support contract.
