DataGridView.ColumnRemoved Event

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

DataGridView.cs

Occurs when a column is removed from the control.

C#

public event System.Windows.Forms.DataGridViewColumnEventHandler? ColumnRemoved;

Event Type

DataGridViewColumnEventHandler

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ColumnRemoved event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. Then ensure that the event handler is associated with the ColumnRemoved event.

C#

private void DataGridView1_ColumnRemoved(Object sender, DataGridViewColumnEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Column", e.Column );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ColumnRemoved Event" );
}
