Post the code.

private void dgvForm_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            int rowIndex = 0;
            int rowCount = 0;

            

            DataGridViewComboBoxCell cell = dgvForm.CurrentCell as DataGridViewComboBoxCell;

            if (cell != null && !cell.Items.Contains(e.FormattedValue))
            {
                // Insert the new value into position 0
                // in the item collection of the cell
                cell.Items.Insert(0, properStr);
                // When setting the Value of the cell, the  
                // string is not shown until it has been
                // comitted. The code below will make sure 
                // it is committed directly.
                if (dgvForm.IsCurrentCellDirty)
                {
                    // Ensure the inserted value will 
                    // be shown directly.
                    // First tell the DataGridView to commit 
                    // itself using the Commit context...
                    dgvForm.CommitEdit(DataGridViewDataErrorContexts.Commit);
                }
                // ...then set the Value that needs 
                // to be committed in order to be displayed directly.
                cell.Value = cell.Items[0];
            }
}
