I am supporting some Telerik code that has a GridView with 30 columns of GridViewDataColumn type.  As part of the GridView, there is a RadGridView.RowDetailsTemplate that includes a UserControl that is basically an editor of the columns of the GridView. 

Bindings seems to be refreshing the GridView columns just fine when the columns of the GridView are visible to the user.  Since this GridView has about 30 columns, only about 10 columns are visible to the user at any given time.  As user scrolls horizontally, he can see the other columns.   If the columns being edited by the user are not visible at the time of editing, those values are not updated 50% of the time when he scrolls the grid columns into view.   Some columns are being updated correctly and some columns would not be updated correctly.  If the columns are visible at the time of editing, we have not noticed the cells not be updated correctly.
 
To test out our viewmodel, I rewrote part of the grid using the same bindings with a non-Telerik grid, everything seems to refresh just fine as the values are being edited and the gridview being scrolled.

We are using the current Telerik control for WPF 4.

Any suggestions would be appreciated.

Thanks,
Milt

Hi Milt,

In order to suggest any further, I would need some more details. How do you define and bind your columns ? How do you edit them - from the code-behind ?
Generally, any relevant information or code-snippet would be helpful.
