ListView.OnDrawColumnHeader(DrawListViewColumnHeaderEventArgs) Method

Definition

Raises the DrawColumnHeader event.

protected:
 virtual void OnDrawColumnHeader(System::Windows::Forms::DrawListViewColumnHeaderEventArgs ^ e);
protected virtual void OnDrawColumnHeader (System.Windows.Forms.DrawListViewColumnHeaderEventArgs e);
abstract member OnDrawColumnHeader : System.Windows.Forms.DrawListViewColumnHeaderEventArgs -> unit
override this.OnDrawColumnHeader : System.Windows.Forms.DrawListViewColumnHeaderEventArgs -> unit
Protected Overridable Sub OnDrawColumnHeader (e As DrawListViewColumnHeaderEventArgs)

Parameters

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnDrawColumnHeader method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnDrawColumnHeader(DrawListViewColumnHeaderEventArgs) in a derived class, be sure to call the base class's OnDrawColumnHeader(DrawListViewColumnHeaderEventArgs) method so that registered delegates receive the event.
