c#: TabControl隐藏选项卡(WizardPages)

如Delphi之TPageControl控件,其TTabSheet有TabVisible属性,在制作类似Wizard页面切换时,甚为有用。

而c#对应之TabControl控件,其页面TabPage无此属性,实现Tab标题栏隐藏,方法诸多,却不够易用,不甚方便。

*上找到另一方法,其移自微软社区,即扩展TabControl控件接管绘制消息,相比来说 ,易用多点。

贴代码如下:

using System;
using System.Windows.Forms; public class TablessControl : TabControl
{
protected override void WndProc(ref Message m)
{
// Hide tabs by trapping the TCM_ADJUSTRECT message
if (m.Msg == 0x1328 && !DesignMode)
m.Result = (IntPtr);
else
base.WndProc(ref m);
} protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == (Keys.Control | Keys.Tab) || keyData == (Keys.Control | Keys.Shift | Keys.Tab) || keyData == (Keys.Left) || keyData == (Keys.Right))
return true; return base.ProcessCmdKey(ref msg, keyData);
}
}

另一种实现方式,发布TabsVisible属性:

using System;
using System.ComponentModel;
using System.Windows.Forms; public class WizardPages : TabControl {
private bool tabsVisible; [DefaultValue(false)]
public bool TabsVisible {
get { return tabsVisible; }
set {
if (tabsVisible == value) return;
tabsVisible = value;
RecreateHandle();
}
} protected override void WndProc(ref Message m) {
// Hide tabs by trapping the TCM_ADJUSTRECT message
if (m.Msg == 0x1328) {
if (!tabsVisible && !DesignMode) {
m.Result = (IntPtr);
return;
}
}
base.WndProc(ref m);
} protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == (Keys.Control | Keys.Tab) || keyData == (Keys.Control | Keys.Shift | Keys.Tab) || keyData == (Keys.Left) || keyData == (Keys.Right))
return true; return base.ProcessCmdKey(ref msg, keyData);
}
}

设计期间,与正常TabControl一样:
