Occurs when a column is added to the control.
public:
event System::Windows::Forms::DataGridViewColumnEventHandler ^ ColumnAdded;public event System.Windows.Forms.DataGridViewColumnEventHandler ColumnAdded;public event System.Windows.Forms.DataGridViewColumnEventHandler? ColumnAdded;member this.ColumnAdded : System.Windows.Forms.DataGridViewColumnEventHandler Public Custom Event ColumnAdded As DataGridViewColumnEventHandler Event Type
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ColumnAdded 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 ColumnAdded event.
private void DataGridView1_ColumnAdded(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(), "ColumnAdded Event" );
}
Private Sub DataGridView1_ColumnAdded(sender as Object, e as DataGridViewColumnEventArgs) _
Handles DataGridView1.ColumnAdded
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "Column", e.Column)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"ColumnAdded Event")
End Sub
