We are glad you have found a way to customize the behavior of the AutoCompleteBox. As for the the issue with the dropdown remaining open I checked the behavior of the RadComboBox and RadDropDownList in the Grid's popup editor in version 2016.3.1027 and their dropdowns close immediately after clicking anywhere on the window, so for example clicking on the window's header in order to drag it or clicking on its close button removes the focus from the RadComboBox or RadDropDownList and the dropdown closes automatically. This is their behavior by design.
Please, check which particular control you are using, whether it is a RadDropDownList, RadComboBox, asp:DropDownList, etc. and open a new thread about the issue you are experiencing with product RadGrid in case the behavior is specifically related to using the control in RadGrid, providing as much details as possible on your scenario and controls configuration. It would be helpful if you could isolate the issue in a sample project as explained in our blog post
, as this would help us with reproducing it.
We try to keep the threads consistent with their original subject. This makes them more maintainable, easier to track and facilitates finding the relevant information they contain.
