但是你可以拦截这个控件的双击消息。 以下代码可加在控件的父窗口（假设为Form1），并在Form1初始化后安装拦截挂钩。同样的方法也可屏蔽那控件的其它消息，如屏蔽它的右键事件。
private const int GWL_WNDPROC = -4;
private const int WM_LBUTTONDOWN=0x0201;
private const int WM_LBUTTONUP=0x0202;
private const int WM_LBUTTONDBLCLK=0x0203;//双击消息
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr SetWindowLong(IntPtr hWnd, int nIndex, MyWndProc wndProc);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern IntPtr CallWindowProc(IntPtr wndProc, IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);
public delegate IntPtr MyWndProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);
private IntPtr OldWndProc = IntPtr.Zero;
private MyWndProc Wpr = null;
private IntPtr MyControlWndProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam) {
switch (msg)
{ case WM_LBUTTONDBLCLK://拦截双击消息
/*在这里,你想干什么就干什么*/
....................... .......................
return (IntPtr)0;
default:
return CallWindowProc(OldWndProc, hWnd, msg, wParam, lParam);
}
}
//假设那个控件变量名为 _thatControl
private void InitializeThatControl()
{ //初始化的时候安装消息拦截
this.Wpr = new MyWndProc(this.MyControlWndProc);
this.OldWndProc = SetWindowLong(_thatControl.Handle, GWL_WNDPROC, Wpr);
}
public Form1()
{
InitializeComponent();
InitializeThatControl();//加这句,在Form初始化后安装消息拦截
}
