Hello, I have a XamMultiColumnComboEditor with 2 columns (see code below). The data in the comboeditor is sorted on the first column now, but I want to be able to sort on both. (clicking on header Test would result in changing the sort to the column Test and same behavior for column product)
<ig:XamMultiColumnComboEditor Name="cmbTest" ItemsSource="{Binding TestCollection}" DisplayMemberPath="Value.DisplayMember" SelectedItem="{Binding SelectedTest,Mode=TwoWay}" AutoGenerateColumns="False"> <ig:XamMultiColumnComboEditor.Columns> <ig:TextComboColumn Key="Value.Description" HeaderText="Test" Width="*" /> <ig:TextComboColumn Key="Value.Product" HeaderText="Product" Width="*" /> </ig:XamMultiColumnComboEditor.Columns> </ig:XamMultiColumnComboEditor>
How can I do this with this editor?

I have been looking into the requirement that you are having and I managed to implement the sorting functionality for the XamMultiColumnComboEditor.
To allow sorting the editor, when clicking on the headers of the columns, you should create a class that derives from the XamMultiColumnComboEditor and expose its protected DataManger property. Using the DataManager, you can sort the items in the editor, by adding SortContext objects to the DataManagerBase’s Sort collection.
After exposing the property, you can create a style for the ComboHeaderCellControl and handle the MouseLeftButtonDown event, using an EventSetter. In the event handler for the event, you can get the column that should be sorted and add a SortContext for this column.
I am attaching a sample application that shows how you can implement this approach.
Please let me know if you need any further assistance on the matter.
Sincerely,
Krasimir, MCPD
