Hello,

I'd like to suppress the dropdown from opening when I change the Text property of my combobox. Presently, I'm doing:

                cboRecord.Text = psName + " [" + psID + "]";
                cboRecord.CloseDropDown();
                cboMasterfile.Text = Sands.GetFullMasterfile(psMasterfile);
                cboMasterfile.CloseDropDown();

But when this executes, you still see the dropdown open and then immediately close, which looks buggy. Is there any way to avoid having it open altogether? I've tried disabling the control before and enabling after, but that does not work.

Thanks!
Jeremy

Hello Jeremy Murtishaw,

You can achieve this behavior by using a boolean flag. You set this flag to true while editing the text and when you are done, you set it to false. Then in the PopupOpening event you check for this flag and cancel the opening of the drop down. You can access the PopupOpening event through the ComboBoxElement property of RadComboBox.

Best wishes,
