Hi, Ric!

May be that comes from the numeric data type - try the following:
- Extend your data source with a 3rd column containing cItemCode = STR(ItemCode, 2).
- Place this new column cItemCode as first column in the combobox. Note: The contents of 1st column is always displayed in the textbox part of the combo!
- Set BoundColumn to "2", because the "old" ItemCode column is now the second column of the combobox!
- Set ColumnWidth to "0,xx,yy" or to "xx,0,yy" to supress on of the two ItemCode columns if the combobox is expanded!

... and that's it - in principle <s>!
Play something arround with this stuff and you will find the best way for yourself <s>!
