Characters are lost when pressing multiple keyboard keys in quick succession.

To reproduce this:

1. Set the ShowToolTipOnTrimmedText property of RadGridView to True.
2. Hover a cell with trimmed text.
3. Before the tooltip shows, move the mouse quickly, outside of the RadGridView control.
4. Regardless of the fact that the mouse cursor is outside of the RadGridView control, the tooltip showing is not canceled and it shows after a second.

To resolve this, set the ShowToolTipOnTrimmedText of the gridview columns instead of the RadGridView control.

for radgridview,if CanUserFreezeColumns="True" ,
when adjust the FreezeColumnsResizer to the right,and then resize the left colum'width,
if exceed the visual area,these exceed area's column will disappear!
for example,the data virtualization sample for the radgridview,if set the FreezeColumnsResizer
to the 'Unit_Price' column behind,then adjust the 'Product_ID' column width to exceed the visual area,
at last by scroll,you can't find the exceed visual area columns

Change the Default Selected Filter Operator:
https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-change-the-default-selected-filter-operator

This doesn't work for boolean columns, if the property "ShouldGenerateFieldFilterEditors" of the column is set to "True". 

Please see the attached example.

Using such negative margin leads to some parts of the template to be actually outside of the control boundaries.

A possible workaround is to show and hide the columns.

foreach (GridViewColumn col in TestGridView.Columns)
			{
				bool visibility = col.IsVisible;
				col.IsVisible = true;
				col.IsVisible = visibility;
			}

ArgumentOutOfRangeException is thrown when performing a CollectionChange with Replace action on the underlying collection and there's an applied FilterDescriptor.
