datagridviewcombobox event s

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 sender,DataGridViewEditingControlShowingEventArgs 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;

}
