DataGridViewEditingControlShowingEventHandler Delegate

 

Represents the method that will handle the EditingControlShowing event of a DataGridView.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public delegate void DataGridViewEditingControlShowingEventHandler(
	object sender,
	DataGridViewEditingControlShowingEventArgs e
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Windows.Forms.DataGridViewEditingControlShowingEventArgs

A DataGridViewEditingControlShowingEventArgs that contains the event data.

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.

For more information about handling events, see NIB: Consuming Events.

When you create a DataGridViewEditingControlShowingEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see NIB: Events and Delegates.

The following code example illustrates how to handle this event to change the BackColor property of the current cell. To run this example, paste the code into a form that contains a DataGridView named dataGridView1 and ensure that the EditingControlShowing event is associated with the event handler.

private void dataGridView1_EditingControlShowing(object sender, 
    DataGridViewEditingControlShowingEventArgs e)
{
    e.CellStyle.BackColor = Color.Aquamarine;
}
