Hi Mike Treat,
Thank you for your questions. You can set DropDown height through DropDownHeight
property. You can get the current screen size from PrimiryScreen.Bounds
property. Please, consider the following code:
screenHeight = Screen.PrimaryScreen.Bounds.Height;
.radMultiColumnComboBox2.MultiColumnComboBoxElement.DropDownHeight = (
screenHeight * 0.6);
Hope this helps. Do not hesitate to contact me again if you have other questions.
