JScript supports the use of events, but not the declaration of new ones.
This event lets you customize the appearance of a ListView control using owner drawing. It is raised only when the OwnerDraw property is set to true and the View property is set to View.Details. This event can occur for each column header in the control. For more information on owner drawing, see the OwnerDraw property reference topic.
For more information about handling events, see Consuming Events.
The following code example provides an implementation of a DrawColumnHeader event handler. For the complete example, including the implementation of the DrawSubItem event handler, see the OwnerDraw reference topic.
' Draws column headers. Private Sub listView1_DrawColumnHeader(ByVal sender As Object, _ ByVal e As DrawListViewColumnHeaderEventArgs) _ Handles listView1.DrawColumnHeader Dim sf As New StringFormat() Try ' Store the column text alignment, letting it default ' to Left if it has not been set to Center or Right. Select Case e.Header.TextAlign Case HorizontalAlignment.Center sf.Alignment = StringAlignment.Center Case HorizontalAlignment.Right sf.Alignment = StringAlignment.Far End Select ' Draw the standard header background. e.DrawBackground() ' Draw the header text. Dim headerFont As New Font("Helvetica", 10, FontStyle.Bold) Try e.Graphics.DrawString(e.Header.Text, headerFont, _ Brushes.Black, e.Bounds, sf) Finally headerFont.Dispose() End Try Finally sf.Dispose() End Try End Sub
