I am struggling to find way to color the tab headers of a tabpage in WinForms. There are solutions to color the current indexed tab using OnDrawItem event but can it be possible to color all the tabs with different colors at a time to make them intuitive for user for a certain behavior.

推荐答案

是的，有没有需要任何的Win32代码。你只需要设置选项卡控制DrawMode属性为OwnerDrawFixed，然后处理标签控件的DrawItem事件。

Yes, there is no need for any win32 code. You just need to set the tab controls DrawMode property to 'OwnerDrawFixed' and then handle the tab control's DrawItem event.

下面的代码演示如何：

private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{
    // This event is called once for each tab button in your tab control

    // First paint the background with a color based on the current tab

   // e.Index is the index of the tab in the TabPages collection.
    switch (e.Index )
    {
        case 0:
            e.Graphics.FillRectangle(new SolidBrush(Color.Red), e.Bounds);
            break;
        case 1:
            e.Graphics.FillRectangle(new SolidBrush(Color.Blue), e.Bounds);
            break;
        default:
            break;
    }

    // Then draw the current tab button text 
    Rectangle paddedBounds=e.Bounds;
    paddedBounds.Inflate(-2,-2);  
    e.Graphics.DrawString(tabControl1.TabPages[e.Index].Text, this.Font, SystemBrushes.HighlightText, paddedBounds);

}

设置DrawMode为OwnerDrawnFixed是指每个选项卡按钮有为相同的尺寸（即固定）。

Setting the DrawMode to 'OwnerDrawnFixed' means each tab button has to be the same size (ie Fixed).

不过，如果你想改变所有标签按钮的大小，您可以在标签控件的SizeMode属性设置为固定，然后更改ItemSize属性。

However if you want to change the size of all tab buttons, you can set the tab control's SizeMode property to 'Fixed' and then change the ItemSize property.
