Add an option to clear all filters at once to the column filters.

Rows get duplicated when SortDescriptors are applied and items are added to SelectedItems collection by a behaviour.

Application hangs on start up if GroupRenderMode is set to Nested, there is a column with Width Star and a group descriptor applied.

Cell gets out of the edit mode when new items are added in the collection. The same scenario works correctly if alternation is applied by RowStyleSelector. 

When RadGridView is grouped by a column with ShowColumnWhenGrouped property set to False and GroupDescriptors are cleared, the column does not get visible. 

These issues should be resolved with lib version 2014.3.1110.

Resolved with lib version 2014.2.0825.

Available in LIB version 2017.1.206 , it will be also available in the R1 2017 SP1 Release.

RadGridView is consuming resources when its IsBusy property is set to False in Windows8, Windows8Touch, Office2013 themes. 

We are using Radgridview in our wpf application which is autogenerated using Class Models. When the number of columns are quite huge(more than 35-40 columns), the performance of the horizontal scrollbar is quite poor and even worst when the data on the Grid is huge. Infact the experience it gives while scrolling seems as if the scrollbar is continuously growing. I have tried the following settings on the RadGridView in the xaml but there is no significant improvement in the performance:

EnableColumnVirtualization="True" EnableRowVirtualization="True" VirtualizingPanel.IsVirtualizing="True" VirtualizingPanel.VirtualizationMode="Recycling" ScrollViewer.CanContentScroll="False" ScrollMode="Deferred"

When a gridview is placed in TabControl, the following CodedUI tests will fail:

Test 1. Click on a column header to sort by that column.

Test 2. Click on a drop-down button to filter a column.

Test 3. Drag a column to group by it. 

The workaround could be using QueryableCollectionView instead. Still, it does not suggest the exact same functionality as ICollectionView.

ValidationErrorHandler does not get invoked when validating in view mode and System.ComponentModel.INotifyDataErrorInfo interface is implemented.
