Hello Venkata,

Thank you for your post. I have been looking into your question and to use the XamMultiColumnComboEditor in a WPF application you need the following assemblies added to your project:

1. InfragisticsWPF4.Controls.Editors.XamComboEditor.v14.1

2. InfragisticsWPF4.DataManager.v14.1

3. InfragisticsWPF4.v14.1

And the XamMultiColumnComboEditor is in the xmlns:ig=http://schemas.infragistics.com/xaml xml namespace mapping. You can read more details on how to use the XamMultiColumnComboEditor here: http://help.infragistics.com/Doc/WPF/current/CLR4.0/?page=xamMultiColumnComboEditor.html.

If you wish to use it as an editor for the XamDataGrid, you can create a custom control that derives from the ValueEditor, since the XamDataGrid allows only ValueEditor based control to be used as a Field editor, and use the XamMultiColumnComboEditor in the custom ValueEditor. 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
