Hi Peter
You will have to derive from ComboDropDown control and override the ProcessDialogKey in your derived control to catch the Up and Down keys.

ProcessDialogKey is never called for directional keys

Hi Peter
Yes, that seems to be the case. Sorry. You need to override ProcessCmdKey instead. Here is a derived ComboDropDown that does what you are looking for:
public class MyComboDropDown : Syncfusion.Windows.Forms.Tools.ComboDropDown
{
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData==Keys.Left ||keyData==Keys.Right || keyData==Keys.Up || keyData==Keys.Down)
{
MessageBox.Show("Arrow Key: " + keyData.ToString(),"MyComboDropDown");
}
return base.ProcessCmdKey (ref msg, keyData);
}
}
Regards
Arun
