RichTextBox.Redo RichTextBox.Redo RichTextBox.Redo RichTextBox.Redo Method

Definition

Reapplies the last operation that was undone in the control.

public:
 void Redo();
public void Redo ();
member this.Redo : unit -> unit
Public Sub Redo ()

Examples

The following code example demonstrates how to use the CanRedo and RedoActionName properties, and the Redo method, to restrict a redo operation to any action except the deletion of text. This example requires that you have a form that contains a RichTextBox control and that an operation within the RichTextBox has been performed and undone before the code in this example is called.

private:
   void RedoAllButDeletes()
   {
      // Determines if a Redo operation can be performed.
      if ( richTextBox1->CanRedo == true )
      {
         // Determines if the redo operation deletes text.
         if (  !richTextBox1->RedoActionName->Equals( "Delete" ) )
         // Perform the redo.
         richTextBox1->Redo();
      }
   }
private void RedoAllButDeletes()
{
	// Determines if a Redo operation can be performed.
	if(richTextBox1.CanRedo == true)
	{
		// Determines if the redo operation deletes text.
		if (richTextBox1.RedoActionName != "Delete")
			// Perform the redo.
			richTextBox1.Redo();
	}
}
Private Sub RedoAllButDeletes()

    ' Determines if a Redo operation can be performed.
    If richTextBox1.CanRedo = True Then
        ' Determines if the redo operation deletes text.
        If richTextBox1.RedoActionName <> "Delete" Then
            ' Perform the redo.
            richTextBox1.Redo()
        End If
    End If
End Sub

Remarks

You can then use the Redo method to reapply the last undo operation to the control. The CanRedo method enables you to determine whether the last operation the user has undone can be reapplied to the control.
