ListView.DrawColumnHeader Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when the details view of a ListView is drawn and the OwnerDraw property is set to true.

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

public event DrawListViewColumnHeaderEventHandler DrawColumnHeader
/** @event */
public void add_DrawColumnHeader (DrawListViewColumnHeaderEventHandler value)

/** @event */
public void remove_DrawColumnHeader (DrawListViewColumnHeaderEventHandler value)

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 void listView1_DrawColumnHeader(object sender,
    DrawListViewColumnHeaderEventArgs e)
{
    using (StringFormat sf = new StringFormat())
    {
        // Store the column text alignment, letting it default
        // to Left if it has not been set to Center or Right.
        switch (e.Header.TextAlign)
        {
            case HorizontalAlignment.Center:
                sf.Alignment = StringAlignment.Center;
                break;
            case HorizontalAlignment.Right:
                sf.Alignment = StringAlignment.Far;
                break;
        }

        // Draw the standard header background.
        e.DrawBackground();

        // Draw the header text.
        using (Font headerFont =
                    new Font("Helvetica", 10, FontStyle.Bold))
        {
            e.Graphics.DrawString(e.Header.Text, headerFont,
                Brushes.Black, e.Bounds, sf);
        }
    }
    return;
}
