RadMultiColumnComboBox: DropDown doesn't close always upon selection

Dear support,

I have an issue with a multicolumn combobox that won't close upon selection.

The first time (when it is empty) everything goes well, but the second time (in the attached video around the 10th second) it won't close the dropdown if you select the item again.

I suspect it is acting that way because I select the same item.

It is an annoying behavior because now users need to click on the little arrow to close the drop down, which is not intuitive.

I recorded a video that illustrates this issue.


Many thanks again.

Kind regards.

Hello, Peter,  

Following the provided information and sample video, I was able to observe the same behavior on my end when the user selects an already selected row in the drop down. After further testing I have noticed that the drop down is not closed in the specified situation as of version 2020.2.512.40.

I have logged it in our feedback portal by creating a public thread on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to close the drop down programmatically: 


        private void EditorControl_MouseUp(object sender, MouseEventArgs e)
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
