c# - 如何处理放置在控件对象内的按钮的单击事件？

Question

我有一个控制对象。在控制对象中，我添加了一个 Button 。我想处理 Button 对象的点击事件。

      mapcomponent.MapObjectClick += new MapComponent.MapComponent.MapObjectEventHandler(mapcomponent_MapObjectClick);

    Public void mapcomponent_MapObjectClick(object sender, MapObjectEventArg e)
    {
        if (e != null)
        {
            var obj = sender as Control;
            var txt = obj.FindControl("txt1") as TextBox;
            if (txt != null)
                txt.Text = "hello";

            var btn = obj.FindControl("btn1") as Button;

            if (btn != null)
            {
                btn.Command += new CommandEventHandler(b_Command); //handler
            }
        }
    }

 //Not working
Public void b_Command(object sender, CommandEventArgs e)
    {
       //Want to call This Method
    }

Answer 1

您应该给按钮一个 CommandName 并在 OnCommand 事件中捕获它。

btn.Command += new CommandEventHandler(b_Command); //handler
btn.CommandName = "foo";

Public void b_Command(object sender, CommandEventArgs e)
{
    if(e.CommandName == "foo")
    {
        //Do stuff
    }
}

Answer 2

我不完全确定您的场景的意义是什么，但是如果您想以编程方式调用按钮单击事件，您可以使用该Button.PerformClick()方法。
