synchronizing a combobox with a textfield. I have a form with a textfield and a combobox. The combobox is populated with the department name from the database when the form loads. I would like the textbox to display the corresponding department number when the user selects a department name from the combobox. I have tried using the SelectedIndexChanged event of the combobox but I can't seem to code it to work. This is the code I'm trying to use but it is displaying "DEPARTMENT" in the textbox. Department Code is the primary key of the table.

Dim da = New OracleDataAdapter(strSQL, cn)
da.Fill(dSet, "DEPARTMENT" )
