Are you using style.DataSource, Style.DisplayeMember, style.ValueMember to set up the combobox cell? If so, is your ValueMember a string? If not, then you should not be setting .Text. Instead set .CellValue = to the object (of the proper type).

i am setting it up as a combo box with following code _g[_g.RowCount, CurCol].ChoiceList = ti.enumeration; _g[_g.RowCount, CurCol].CellType = "ComboBox"; where ti.enumeration is a StringCollection please let me know your thoughts. thanks, ak

Here is sample set up you described. http://www.syncfusion.com/Support/user/uploads/GC_Combobox_5b7f9a8f.zip It seems to work OK. Do you have other settings like style.DropDownStyle or style.Exclusive or style.CellValueType that might be affecting this.
