C＃ - 如何防止鼠标滚轮在我的组合框？ [英] C# - how do I prevent mousewheel-scrolling in my combobox?

问题描述

我有一个组合框，我想阻止用户使用鼠标滚轮滚动这些项目。有没有简单的方法？

（C＃，VS2008）

解决方案

使用< ：//msdn.microsoft.com/en-us/library/system.windows.forms.control.mousewheel.aspxrel =nofollow noreferrer> MouseWheel 事件为您的ComboBox：

  void comboBox1_MouseWheel（object sender，MouseEventArgs e）{
（HandledMouseEventArgs）e）.Handled = true; 
} 
  

注意：您必须在代码中创建事件：

  comboBox1.MouseWheel + = new MouseEventHandler（comboBox1_MouseWheel）; 
  

I have a combobox and I want to prevent the user from scrolling through the items with the mousewheel.

Is there an easy way to do that?

(C#, VS2008)

解决方案

Use the MouseWheel event for your ComboBox:

void comboBox1_MouseWheel(object sender, MouseEventArgs e) {
    ((HandledMouseEventArgs)e).Handled = true;
}

Note: you'll have to create event in code:

comboBox1.MouseWheel += new MouseEventHandler(comboBox1_MouseWheel);
