Hi Borislav.

>> When The Combo got Focus Value & DisplayValue are OK but on screen the are blank combo. And If you open the list for choosing always start from top of list (not from current value). <<

This is a known problem.

It only happens with RowSourceTypes 2-Alias and 6-Fields
The solution is to use a RowSourceType of 3-SQL or 5-Array
If you want a detailed discussion of this problem, I can refer you to the thread “Combo In Grid Trouble” in the Compuserve forum archives of January 1998
