Hi Handle the EditingControlShowing event of DataGridView. In this event handler check if the current column is of your interest. this.dataGridView1.EditingControlShowing += new System.Windows.Forms.DataGridViewEditingControlShowingEventHandler(this.dataGridView1_EditingControlShowing); private void dataGridView1_EditingControlShowing(object senderDataGridViewEditingControlShowingEventArgs e) { if (dataGridView1.CurrentCell.ColumnIndex == 0) { // Check box column ComboBox comboBox = e.Control as ComboBox; comboBox.SelectedIndexChanged -= comboBox_SelectedIndexChanged; comboBox.SelectedIndexChanged += new EventHandler(comboBox_SelectedIndexChanged); } } //populating the selected item value in a different cell private void comboBox_SelectedIndexChanged(object sender EventArgs e) { ComboBox comboBox=(ComboBox)sender; if (comboBox.SelectedItem.ToString() != ) { dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[Data].Value = comboBox.SelectedItem; } } Regards Iftikar
