I have a control RadMultiColumn Control on my form as you can see here its showing Telerik.WinControls.UI.GridViewDataRowInfo in the text box however when selecting the option it then throws a null statement.
We are not aware of a similar issue in the RadMultiColumnComboBox control. Looking at the referred video, it appears that the control is not properly data-bound. Can you please check how the attached test project will run on your end? In case the issue persists please let me know how I can observe the exception. A sample project reproducing it would also help.
