问题描述

我有一个userControl，我在那里按钮，我想在我的主表单中调用事件点击。



我尝试了什么：



有我尝试过的，但它没有在表单中工作。



UserControl

Hi,

I have a userControl and I've buttons there, I'd like to call event click in my main form.

What I have tried:

There is what I've tried, but it doesn't work in form.

UserControl

public event EventHandler ButtonClick;

        protected void Button1_Click(object sender, EventArgs e)
        {
            //bubble the event up to the parent
            if (this.ButtonClick != null)
                this.ButtonClick(this, e);
        }

表格

Form

<pre lang="c#">GameField.ButtonClick += new EventHandler(UserControl_ButtonClick);

        protected void UserControl_ButtonClick(object sender, EventArgs e)
        {
            //handle the event 
        }

我无法从主窗体中看到类userControl。这可能是因为我有一个部分类。

I can't see class userControl from main form. It might be cause I've a partial class.

public partial class GameField : UserControl

推荐答案

请看这里：在两个表单之间传输信息，第2部分：子项到父项 [ ^ ] - 它基于表单，但它是与控件完全相同（表格无论如何都来自Control！）。

See here: Transferring information between two forms, Part 2: Child to Parent[^] - it's based on forms, but it's exactly the same with Controls (Forms are derived from Control anyway!).
