Setting ShowDistinctFilters for a RadGridViewColumn hides the distinct values from the filter popup as expected.
But the grid still queries the ItemsSource for distinct values of said column when showing thje popup - it calls something like
MyQueryable.Select(item => item.SomeColumn).Distinct().OrderBy(item => item).Take(1000))
The current row indicator visual (the right pointing arrow) gets hidden if you enter edit mode of a cell (which shows the cell edit indicator) and then press Esc two times. The first time cancel the cell editing and the second time cancels the row editing.
This reproduces in the VisualStudio2013 theme.
To work this around, extract the ControlTemplate of GridViewRow for the VisualStudio2013 theme and add the following MultiTrigger at the bottom of the template (last in the ControlTemplate.Triggers collection).
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsValid" Value="True"/>
<Condition Property="IsCurrent" Value="True"/>
<Condition Property="IsInEditMode" Value="False"/>
</MultiTrigger.Conditions>
<Setter TargetName="NavigatorIndicator" Property="Visibility" Value="Visible"/>
</MultiTrigger>
The aggregate values shown in the group headers are wrong when scrolling. This happens when the EnableColumnVirtualization property is set to False and ColumnAggregatesAlignment is NextToGroupKey or BelowGroupKey.
To work this around, set the EnableColumnVirtualization property to True or ColumnAggregatesAlignment to NoAlignment.

Currently, you can set the data format string of the cells in a GridView column by using the DataFormatString property of the column.
Add a mechanism to select the DataFormatString per cell. For example, this can be done using the CellStyleSelector and a new property in the GridViewCell. Or by introducing DataFormatStringSelector property.
"ArgumentException: Must specify valid information for parsing in the string."
The exception is handled internally but results in the filtering not being applied.
Additionally, to reproduce this, the content of the row details should exceed the viewport.
To work this around, you can set the GroupRenderMode to the legacy Nested layout. Alternatively, you can use the native Expander control instead of RadExpander. Or you can ensure that the contents in the row is less then 35.
SearchStateManager property is null when trying to change any of the properties of the SearchStateManager object in the Loaded event. This behavior is observed when the ShowSearchPanel property is not set to true initially.
While resizing the demos window, radgridview's horizontal scrollbar might flicker when demos viewport size is close to the gridview size.
Hi Telerik,
I have created a sample project for an issue I have found:
Please see the code behind of the sample.
When removing a column from a grid where the display index was changed, and rows are selected, I do get an ArgumentOutOfRangeException.
Any help is appreciated!
Thank you!

To work this around, cancel the reordering in the ColumnReordering event if the drop target column cannot be reordered.
private void RadGridView_ColumnReordering(object sender, Telerik.Windows.Controls.ColumnReorderingEventArgs e)
{
int notResizeableColumnIndex = 1;
if (e.NewDisplayIndex == notResizeableColumnIndex)
{
e.Cancel = true;
}
}
