I have a form with a DGV bound to a SQL database. the DB has three colums: ItemCode, ItemName, Status. The Itemcode field is a combobox complex binded (if this matters), the ItemName colum is a textbox. How can I have the ItemName colum auto insert the text for the ItemName colum when I select the associated ItemCode with the combo box. I'm pretty sure I need to use the "CellValueChanged" event. I'm thinking an IF Then statement with 'e' parameter and colum and row indexes just not sure how to address it.

I am using VB.net 2005. I have a DataGridView with several columns. One of the columns is a ComboBox. What I want to happen is when I populate the DataGridView by binding it with the DataTable I want the ComboBox item that is in the DataTable field to be the one that is shown as selected in the drop down. Then if the user wants to change the value they select a different one from the DropDown (and I will perform some update action). My code displays the correct DataTable item in the ComboBox, but the ComboBox will not drop down so a different item can be selected.
This is the code where I set up the ComboBox in the Form_Load and add all the possible items that can be in the DataTable Destination field.
c10 = New DataGridViewComboBoxColumn
c10.Name = "Destination"
c10.DataPropertyName = "Destination"
c10.MaxDropDownItems = 5
c10.Items.Add(" ")
