DataGridViewAutoSizeColumnsModeEventArgs.PreviousModes Property


Gets an array of the previous values of the column AutoSizeMode properties.

 property cli::array <System::Windows::Forms::DataGridViewAutoSizeColumnMode> ^ PreviousModes { cli::array <System::Windows::Forms::DataGridViewAutoSizeColumnMode> ^ get(); };
public System.Windows.Forms.DataGridViewAutoSizeColumnMode[] PreviousModes { get; }
member this.PreviousModes : System.Windows.Forms.DataGridViewAutoSizeColumnMode[]
Public ReadOnly Property PreviousModes As DataGridViewAutoSizeColumnMode()

Property Value


An array of DataGridViewAutoSizeColumnMode values representing the previous values of the column AutoSizeMode properties.


The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the DataGridView.AutoSizeColumnsModeChanged 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 DataGridView.AutoSizeColumnsModeChanged event.

private void DataGridView1_AutoSizeColumnsModeChanged(Object sender, DataGridViewAutoSizeColumnsModeEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "PreviousModes", e.PreviousModes );
MessageBox.Show(messageBoxCS.ToString(), "AutoSizeColumnsModeChanged Event" );
Private Sub DataGridView1_AutoSizeColumnsModeChanged(sender as Object, e as DataGridViewAutoSizeColumnsModeEventArgs) _ 
     Handles DataGridView1.AutoSizeColumnsModeChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "PreviousModes", e.PreviousModes)
    MessageBox.Show(messageBoxVB.ToString(),"AutoSizeColumnsModeChanged Event")

End Sub
