RadMultiColumnComboBox how to add SortDescriptors to GridViewItemsSourceProvider?

[ClausDC]

How can I add Sorting to the DropDown GridView, so that when the User first opens the DropDown, the GridView is already sorted on one or more columns?

[ClausDC]

This should be in the WPF sub forum.

Hello Claus,

You can achieve your requirement using the InitializeDropDownContentManager event of RadMultiColumnComboBox. In the event handler, you can get the RadGridView control and populate its SortDescriptors. For example:

private void RadMultiColumnComboBox_InitializeDropDownContentManager(object sender, Telerik.Windows.Controls.MultiColumnComboBox.DropDownContentManagerEventArgs e)
{
	var gridView = (RadGridView)e.DropDownContentManager.DropDownElement;
	gridView.SortDescriptors.Add(new SortDescriptor() { Member = "MyProperty", SortDirection = ListSortDirection.Descending });
}
