// 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:

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;
}
' 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, _
