I have created comboBox column in my DataGridView
as
DataGridViewCell ComboCell = new DataGridViewComboBoxCell();
DataGridViewComboBoxColumn comboCol = new DataGridViewComboBoxColumn();
comboCol.AutoComplete = true;

comboCol.CellTemplate = ComboCell;
comboCol.DisplayMember = "MenuName";
comboCol.ValueMember = "MenuID";
comboCol.HeaderText = "Menu Name";
comboCol.DataSource = dealList;
comboCol.Name = "MenuName";
comboCol.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
comboCol.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
comboCol.Width = 120;
Grd.Columns.Add(comboCol);

Now i want if the index in the combobox is changed in this column say "MenuName" then i can assign the selected value to another column say "MenuID"
how can i do this?
Please guide me... Thank you in advance

Hello WaseemAmin,

Unfortunately the DataGridViewComboBoxColumn doesn't expose a SelectedIndexChanged Event. In order to catch an index change of a ComboBoxColumn, you 'll first need to cast the cell to a DataGridViewComboBoxEditingControl and Add an EventHandler to that control. This you will have to do in the EditingControlShowing Event of the DataGridView .

suppose i have a datagridview named as dataGridViewSales .and in the datagridview i have one combobox . Now i want to change the datagrid view second column value according to combobox selected value.

C#

private void dataGridViewSales_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
       {
           ComboBox cb = e.Control as ComboBox;
           if (cb != null)
           {
               cb.SelectedIndexChanged += new EventHandler(selectionchange);
              //here SelectedIndexChanged event is used
           }
       }

and then define selectionchange method

C#

void selectionchange(object sender, EventArgs e)
       {
           try
           {
               ComboBox cb = (ComboBox)sender;
               if (cb.Text == "yes")
               {
                   dataGridViewSales.CurrentRow.Cells[1].Value= "Hello";
//if datagridviewcombobox text is yes then set the first column value to 'Hello'
               }
               else if (cb.Text == "no")
               {
                   dataGridViewSales.CurrentRow.Cells[1].Value = string.Empty;
 //else set the first column  value to empty
               }
           }
           catch { }
       }

thanks
