How do I assign a value to a DataGridViewComboBoxColumn in C#?

I have a DataGridView childDataGridView with a DataGridViewTextBoxColumn cmdSpnIndCol and a DataGridViewComboBoxColumn commandSponsoredIndicator.  

commandSponsoredIndicator has three hard coded Items values: "Select One", "Yes", and "No".  Each row of childDataGridView has the following possible values for cmdSpnIndCol: "Y", "N", or null.

I am trying to iterate through each row of childDataGridView to set commandSponsoredIndicator as follows:

if  cmdSpnIndCol is "Y", then set to "Yes".
if cmdSpnIndCol is "N", then set to "No".
otherwise, set to "Select One".

My code is below.  All is working except the assignment part.  What am I doing wrong?

foreach (DataGridViewRow row in childDataGridView.Rows)
                {
                    if (row.Cells["cmdSponIndCol"].Value.ToString() == "Y")
                    {
                        // not working
                        row.Cells["commandSponsoredIndicator"].Value = "Yes";
                    }
                    else if (row.Cells["cmdSponIndCol"].Value.ToString() == "N")
                    {
                        // not working
                        row.Cells["commandSponsoredIndicator"].Value = "No";
                    }
                    else
                    {
                        // not working
                        row.Cells["commandSponsoredIndicator"].Value = "Select One";
                    }
                 }

Hi

you need to use FindControl to find the control and assign your value

try something like this

row.findcontrol

or why you don't do it before binding to the grid view

datatable dt=Get my date from DB;

then make a for loop and change the vale and assign it to the datatable
then bind it.

use like this:

foreach (DataGridViewRow row in childDataGridView.Rows)
                {
                    if (row.Cells.FindControl("cmdSponIndCol") as TextBox).Text.ToString() == "Y")
                    {
                          //Assign Value
                    }
                }

I ended up creating a new DataTable yesNoTable (with two columns) and binding those DataColumns to the the DataGridViewComboBoxColumn's DisplayedMember and ValueMember properties.  This appears to have solved my problem.
