When a predefined RowTemplate is set with RowStyle property the Adding New Item functionality fails. As a workaround we suggest extracting a Style based on our GridViewRowStyle and targeting the GridViewRow.

Available in LIB version 2016.3.1212, it will be also available in the 2017 R1 release.

GridView allows you to define an AggregateFunction for each column and display the summary information for all cells in the column when there is grouping enabled. This will produce a group header with an aggregate result for each column that has aggreagate functions defined.

Adding and removing columns from the RadGridView's Columns collection doesn't update the aggregate results displayed in the group header.

To work this around, you can remove the GroupDescriptor from the GridView control and add a new instance of the descriptor, when you add/remove an item.

private void RadButton_Click_1(object sender, RoutedEventArgs e)
{
	var column = new GridViewDataColumn() { DataMemberBinding = new System.Windows.Data.Binding("Number1") };
	column.AggregateFunctions.Add(new SumFunction());
	this.gridView.Columns.Add(column);
	
	var descriptor = (GroupDescriptor)this.gridView.GroupDescriptors[0];
	this.gridView.GroupDescriptors.Remove(descriptor);
	this.gridView.GroupDescriptors.Add(new GroupDescriptor() { Member = descriptor.Member });
}

Changing ItemsSource of the GridViewComboBoxColumn runtime leads to empty cells in that column.

Available in LIB version 2017.1.213 , it will be also available in the R1 2017 SP1 Release.

This happens only if there are many columns outside of the viewport (a scrollviewer is shown), with their TabStopMode property set to Skip.

In this case, the navigation needs some time in order to get to the next row and select the first available cell.

A possible workaround for this would be to implement a custom Keyboard Command Provider, and to replace the MoveNext command with a custom one, that moves the current cell, by setting the CurrentCellInfo property of RadGridView.

When using a QueryableCollectionView with a FilterDescriptor and a GroupDescriptor, items which are filtered won't be added to the (new) group after being edited programmatically.

For the time being, the Refresh method of the view can be called to reevaluate this or the filter descriptor can be removed and re-added.

Available in the R1 2017 SP1 Release.

This functionality will be available with Q1 2016 SP.

If I change Column.IsVisibility to FALSE, the column group headers are disappear and not restored.

The problem should be resolved with LIB version 2016.1.404.
