Hi,
I'm using Syncfusion 7.102.0.30 on Win 7.
The multicolumncombobox shows both horizontal and vertical scrollbars. But only the vertical one seems to work properly. It gets highlighted on mouse over etc. Clicking on the horizontal scrollbar closes the drop down portion of the control.
Please refer to the attached sample.
Did I miss something?
Sincerely yours
Christian
