I want the dropdown width to autosize (which is doing now) when the grid content is wider than the combobox's width but only shrink down to the combobox width when the content is not wide enough.
Is this possible?
I think I found a good solution for this. In the InitializeLayout event, set the first column's MinWidth to the width of the control (or whatever minimum width you wanted).
e.Layout.Bands[0].Columns[0].MinWidth = cmbValue.Width;
