MultiColumnComboBox: Binding error is thrown when the dropdown is opened

The following error is thrown when the dropdown of the control is opened: Cannot find governing FrameworkElement or FrameworkContentElement for target element. ... ; target element is 'GridViewItemsSourceProvider; target property is 'ItemsSource' (type 'Object')

If the combobox is placed inside a RadGridView, the error is thrown each time the dropdown is opened (after a commit action).

Hello,

We have introduced two new properties to the GridViewMultiColumnComboBoxColumn - Columns and AutoGenerateColumns. This will allow you to define the columns for the editor directly through the column and you would no longer need a CellEditTemplate. 

The new API will be available in the next Internal Build which should be out on the 10th of February 2020 (2020.1.210).
