复制代码 代码如下:

方法如下：

声明一个事件：

Num_DiscountAmount.MouseWheel +=new MouseEventHandler(Num_DiscountAmount_MouseWheel);

编写一个事件

private void Num_DiscountAmount_MouseWheel(object sender, MouseEventArgs e)

{

HandledMouseEventArgs h = e as HandledMouseEventArgs;

if (h != null)

{

h.Handled = true;

}

}

还有 第三方控件DevExpress.XtraEditors.SpinEdit ,如何禁用鼠标中间键？

方法如下：

声明事件： (SpinEdit1.Controls[0] as DevExpress.XtraEditors.TextBoxMaskBox).MouseWheel += new MouseEventHandler(Frm_MouseWheel);

编写事件：

void Frm_MouseWheel(object sender, MouseEventArgs e)

{

if (e.Delta != 0)

DevExpress.Utils.DXMouseEventArgs.GetMouseArgs(e).Handled = true;

}
