asp.net - 如何以编程方式添加按钮并在单击时调用其事件处理程序？

Question

我想以编程方式创建一个按钮，当我单击该按钮时，我想调用它的事件处理程序......这是我的代码......我做错了什么？

protected void DashboardDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{

    Button objbutton = new Button();
    objbutton.ID = "objbutton";
    objbutton.Text = "Hello";
    form1.Controls.Add(objbutton);
    Page.Controls.Add(form1);
    objbutton.Click += new System.EventHandler(objbutton_Click);


}
protected void objbutton_Click(object sender, EventArgs e)
{
    Response.Write("Hello World");
}

如果我单击objbutton然后DashboardDropDownList_SelectedIndexChanged事件被触发而不是 objbutton_Click

Answer 1

像这样使用

protected void DashboardDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{

    Button objbutton = new Button();
    objbutton.ID = "objbutton";
    objbutton.Click += new System.EventHandler(objbutton_Click);
    objbutton.Text = "Hello";
    form1.Controls.Add(objbutton);


}
protected void objbutton_Click(object sender, EventArgs e)
{
    Response.Write("Hello World");
}
