Hello Friends

I am having combobox in my grid with style as "drop down list box". problem is when focus is on combobox and then If I press up or down arrow it moves in combobox instead of grid.
I want in a way that if combobox is dropped down at that time only pressing up or down should move between combobox. in normal case it should move in grid.

I would appreciate all your help to solve this.

Thanks in advance buddy!

Thanks
Mark
