DataGridViewEditingControlShowingEventArgs.Control Property

The control shown to the user for editing the selected cell's value.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public Control Control { get; }
/** @property */
public Control get_Control ()

public function get Control () : Control

Not applicable.

Property Value

A Control that displays an area for the user to enter or change the selected cell's value.

To customize the display characteristics of the control, set the properties of the object returned by the CellStyle property rather than setting the properties of the control returned by the Control property.

The following code example illustrates the use of this property. In the example, a DataGridView.EditingControlShowing event handler adds a handler for a DataGridViewComboBoxEditingControl event. 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;
}
