How to change Tab Control Background Color (VB.NET)
提问by C PWL
how can I change the grey part into white color? I want my tabcontrol filled with full white color.
如何将灰色部分更改为白色？我希望我的 tabcontrol 充满全白色。
So far what i did is like this:
到目前为止，我所做的是这样的：
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim g As Graphics = e.Graphics
Dim tp As TabPage = TabControl1.TabPages(e.Index)
Dim br As Brush
Dim sf As New StringFormat
Dim r As New RectangleF(e.Bounds.X, e.Bounds.Y + 2, e.Bounds.Width, e.Bounds.Height - 2)
sf.Alignment = StringAlignment.Center
Dim strTitle As String = tp.Text
'If the current index is the Selected Index, change the color
If TabControl1.SelectedIndex = e.Index Then
'this is the background color of the tabpage header
br = New SolidBrush(Color.White) ' chnge to your choice
g.FillRectangle(br, e.Bounds)
'this is the foreground color of the text in the tab header
br = New SolidBrush(Color.Black) ' change to your choice
g.DrawString(strTitle, TabControl1.Font, br, r, sf)
Else
'these are the colors for the unselected tab pages
br = New SolidBrush(Color.White) ' Change this to your preference
g.FillRectangle(br, e.Bounds)
br = New SolidBrush(Color.Black)
g.DrawString(strTitle, TabControl1.Font, br, r, sf)
End If
End Sub
and I also put this at PageLoad function:
我也把它放在 PageLoad 函数中：
TabControl1.DrawMode = TabDrawMode.OwnerDrawFixed
For Each tg As TabPage In TabControl1.TabPages
tg.BackColor = Color.White
Next

Spending fair time to research if someone find a solution; There could be some work around. But according to MSDN Ref.
花大量时间研究是否有人找到了解决方案；可能有一些解决方法。但根据MSDN 参考。
TabControl.BackColor Property

As far as I understand, this is adjustable from user's windows setting. (Highlight Color) of TabControl, Forms and other controls; otherwise MS could simply turn this property on.
据我了解，这可以从用户的 Windows 设置中进行调整。( Highlight Color) of TabControl、Forms 和其他控件；否则 MS 可以简单地打开此属性。
