If you have the following model, the columns that show the Test and Date properties (in the derived class) cannot be sorted or filtered.
Bind a grid to a DataView
Start editing and change the values of a few cells.
Press Escape twice to cancel the edit of the entire row.
Expected: the values return to the old values
Actual: the values remain the last entered ones
When we make frozen column width bigger than the window will hide other columns. Scrolling is applied only to not frozen columns. So we can't scroll to see other columns. A possible workaround is to set MaxWidth property of the column.
When the ItemsSource of the RadGridView is reset, disctinct values remain checked in the Filtering Popup.
For a workaround, check the attached project.
