ContentsResizedEventArgs Class

Provides data for the ContentsResized event.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public class ContentsResizedEventArgs : EventArgs
public class ContentsResizedEventArgs extends EventArgs
public class ContentsResizedEventArgs extends EventArgs
Not applicable.

This event is raised when the bounding rectangle necessary to accept new text changes. If the text within the control spans multiple lines, the requested rectangle will always be the width of the control. You can handle this event in your control to implement auto-resizing for multiline RichTextBox controls. The ContentsResizedEventArgs identifies the requested size of the RichTextBox.

The following code example demonstrates the use of this type. In the example, an event handler reports on the occurrence of the ContentsResized 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 Show with System.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 RichTextBox named RichTextBox1. Then ensure that the event handler is associated with the ContentsResized event.

private void RichTextBox1_ContentsResized(Object sender, ContentsResizedEventArgs e) {

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