是的，Ramug10是对的，你不能有lable的点击事件。如果您使用按钮，您可以执行以下操作。

 btnPrint.Click + =  new  EventHandler（ btnPrint_Click）; 



 void  btnPrint_Click（ object  sender， EventArgs e）
 {
你的逻辑在这里
} 

使用下面的代码..
btnnew.ID =btnSubmit;
form1.Controls.Add（btnnew）;
btnnew.Click + = btnnew_Click;

在负载之外添加此事件处理程序方法

  void  btnnew_Click（ object  sender，EventArgs e）
 { 
 //  点击此按钮时添加逻辑 
} 

Hi Developers,

Am working on a sharepoint webpart project,

I have created one label using below code

Label lbltest = new Label ();

Controls.add(lbltest);

Now i want to write a click event for this label , how can i do that?
There is no asp design page only c # file since it is sharepoint project.

yeah Ramug10 is right you can not have click event of lable. if you are using button you can do something like below.

btnPrint.Click += new EventHandler(btnPrint_Click);



void btnPrint_Click(object sender, EventArgs e)
       {
           your logic goes here
       }

Use below code..

In Page_Load

Button btnnew = new Button();
            btnnew.ID = "btnSubmit";
            form1.Controls.Add(btnnew);
            btnnew.Click += btnnew_Click;

add this Event handler method outside the load

void btnnew_Click(object sender, EventArgs e)
       {
          //Add your logic  when this button click fired
       }
