Hi it,s easy,If you have a ComboBoxColumn in your DataGridView and you want to know what is the selected index of the combo box, then you need to do this: 1. Handle the EditingControlShowing event of DataGridView. In this event handler, check if the current column is of our interest. Then we create a temporary ComboBox object and get the selected index: Code private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { if (dataGridView1.CurrentCell.ColumnIndex == 0) { // Check box column ComboBox comboBox = e.Control as ComboBox; comboBox.SelectedIndexChanged += new EventHandler(comboBox_SelectedIndexChanged); } } void comboBox_SelectedIndexChanged(object sender, EventArgs e) { int selectedIndex = ((ComboBox)sender).SelectedIndex; MessageBox.Show("Selected Index = " + selectedIndex); } That's all , if its help Please mark as answer :) Thank you

There is a problem with the above reply. Since EditControlShowing event will be fired when the edit control is showing. So the above code will add SelectedIndexChanged event handler many times. This is not you want. So the correct way is to unsubscribe first, and then subscribe. Here you can find the correct code: http://social.msdn.microsoft.com/Forums/en-US/winformsdatacontrols/thread/a44622c0-74e1-463b-97b9-27b87513747e#faq17
