业主绘图控制系统-背景

所有者绘制意味着我必须编写自己的绘图方法。

但是，如何告诉系统在没有文本的情况下绘制 ListView 项目的“系统”背景？我想手动绘制文本，而不是（蓝色）背景。

Protected Overrides Sub OnDrawItem(ByVal e As System.Windows.Forms.DrawListViewItemEventArgs)
    MyBase.OnDrawItem(e)

    e.DrawBackground()
    TextRenderer.DrawText(e.Graphics, "My Text", e.Item.Font, e.Bounds, e.Item.ForeColor)
End Sub

在Tile视图中使用ListView，我只看到“我的文本”。

原文

Owner draw implies that I have to code my own drawing methods.

However, how can I tell the system to draw the "system" background of my ListView item, without the text? I would like to manually draw the text, not the (blue) background.

Protected Overrides Sub OnDrawItem(ByVal e As System.Windows.Forms.DrawListViewItemEventArgs)
    MyBase.OnDrawItem(e)

    e.DrawBackground()
    TextRenderer.DrawText(e.Graphics, "My Text", e.Item.Font, e.Bounds, e.Item.ForeColor)
End Sub

Using ListView in Tile view, I just see "My Text".

Protected Overrides Sub OnDrawItem(ByVal e As DrawListViewItemEventArgs)
    MyBase.OnDrawItem(e)

  e.DrawBackground()
  If (e.State And ListViewItemStates.Selected) <> 0 Then
    e.Graphics.FillRectangle(SystemBrushes.Highlight, e.Bounds)
    e.DrawFocusRectangle()
    TextRenderer.DrawText(e.Graphics, "My Text", e.Item.Font, e.Bounds, SystemColors.HighlightText, Color.Empty)
  Else
    TextRenderer.DrawText(e.Graphics, "My Text", e.Item.Font, e.Bounds, e.Item.ForeColor)
  End If
End Sub
