Examples

The following code example demonstrates how to use an DataGridView.EditingControlShowing event handler to add a handler for a DataGridViewComboBoxEditingControl event. In the example, the editing control is cast to a ComboBox to handle the ComboBox.SelectedIndexChanged event.

private DataGridView dataGridView1 = new DataGridView();

private void AddColorColumn()
{
    DataGridViewComboBoxColumn comboBoxColumn =
        new DataGridViewComboBoxColumn();
    comboBoxColumn.Items.AddRange(
        Color.Red, Color.Yellow, Color.Green, Color.Blue);
    comboBoxColumn.ValueType = typeof(Color);
    dataGridView1.Columns.Add(comboBoxColumn);
    dataGridView1.EditingControlShowing +=
        new DataGridViewEditingControlShowingEventHandler(
        dataGridView1_EditingControlShowing);
}

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox combo = e.Control as ComboBox;
    if (combo != null)
    {
        // Remove an existing event-handler, if present, to avoid 
        // adding multiple handlers when the editing control is reused.
        combo.SelectedIndexChanged -=
            new EventHandler(ComboBox_SelectedIndexChanged);

        // Add the event handler. 
        combo.SelectedIndexChanged +=
            new EventHandler(ComboBox_SelectedIndexChanged);
    }
}

private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    ((ComboBox)sender).BackColor = (Color)((ComboBox)sender).SelectedItem;
}

Private WithEvents dataGridView1 As New DataGridView()

Private Sub AddColorColumn()

    Dim comboBoxColumn As New DataGridViewComboBoxColumn()
    comboBoxColumn.Items.AddRange( _
        Color.Red, Color.Yellow, Color.Green, Color.Blue)
    comboBoxColumn.ValueType = GetType(Color)
    dataGridView1.Columns.Add(comboBoxColumn)

End Sub

Private Sub dataGridView1_EditingControlShowing(ByVal sender As Object, _
    ByVal e As DataGridViewEditingControlShowingEventArgs) _
    Handles dataGridView1.EditingControlShowing

    Dim combo As ComboBox = CType(e.Control, ComboBox)
    If (combo IsNot Nothing) Then

        ' Remove an existing event-handler, if present, to avoid 
        ' adding multiple handlers when the editing control is reused.
        RemoveHandler combo.SelectedIndexChanged, _
            New EventHandler(AddressOf ComboBox_SelectedIndexChanged)

        ' Add the event handler. 
        AddHandler combo.SelectedIndexChanged, _
            New EventHandler(AddressOf ComboBox_SelectedIndexChanged)

    End If

End Sub

Private Sub ComboBox_SelectedIndexChanged( _
    ByVal sender As Object, ByVal e As EventArgs)

    Dim comboBox1 As ComboBox = CType(sender, ComboBox)
    comboBox1.BackColor = _
        CType(CType(sender, ComboBox).SelectedItem, Color)

End Sub

Remarks

The DataGridViewComboBoxEditingControl class is a specialized type of ComboBox that implements the IDataGridViewEditingControl interface, allowing it to be hosted in a DataGridViewComboBoxCell when the cell is in edit mode. When a DataGridViewComboBoxCell is in edit mode, you can retrieve the DataGridViewComboBoxEditingControl through the EditingControl property of the DataGridView control.

Handle the EditingControlShowing event to perform custom initialization of the editing control when a cell enters edit mode. To customize the display characteristics of the control, set the properties of the object returned by the DataGridViewEditingControlShowingEventArgs.CellStyle property rather than setting the properties of the control returned by the DataGridViewEditingControlShowingEventArgs.Control property.
