Hi Kevin Meyer,
Unfortunately, the RadComboBox
has been designed to behave in such a way. Currently, there is no way to change the behavior through the API. We are aware of this issue and it is in our TODO list. However, to avoid this behavior, I would suggest the following workaround :
private void radComboBox1_DropDownClosed(object sender, Telerik.WinControls.UI.RadPopupClosedEventArgs args)
radComboBox1.SelectionLength = 0;
to 0 will remove the selection, but will set the textbox caret in the beginning of the text.
This you could also do when the Up/Down key is pressed to handle the case when the user uses the arrow keys to select an item.
If you have any additional questions, please write us again.
