How do you select multiple items when using the xamMultiColumnComboEditor in a MVVM environment?

I believe this is a good solution: http://es.infragistics.com/community/blogs/devin_rader/archive/2011/06/01/using-behaviors-to-synchronize-selected-items-of-infragistics-silverlight-controls-to-a-viewmodel.aspx

Switch the xamcomboeditor for the xammulticolumncomboeditor and you should be good to go.

Hello,

Thank you for your post. I have been looking into it and since the XamMultiColumnComboEditor’s SelectedItems Property is read-only you are not able to bound it. This is a WPF limitation. There it is an issue submitted to the MS forums:

Also here it is explained how you can work around this:

Hope this helps you.
