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.

Hi Kavitha,

Asp.Net Label control doesn't have click event so you can use linkbutton instead of label.

Thanks for you replay,
Even am ready to use button , but i dont know how to write that clcik event.
Usually what i do is i will create button in asp page and double click on that button will take me to click event. But here am adding button using c# code
Button btn = new button();
so how can i write event for this?

// this can be put in form/page load or form constructor
maybe this is a solution:
btn.Click += new EventHandler(MyClick);

// and this function should be added as a member function of form or page
private void MyClick(object sender, EventArgs e)
{
}

What do you mean by "writing event"? You can only handle this event, nothing else.

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

C#

btnPrint.Click += new EventHandler(btnPrint_Click);



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

Solution 2

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

C#

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

Ramug10 27-Feb-14 2:09am

yes, you can use this for webapplication.

Am Gayathri 27-Feb-14 2:25am

How?
button test = new button().

I dont see any property like .Click for this button.(This is a stem.Web.UI.WebControls button not system.forms.button)

Ramug10 27-Feb-14 2:51am

you should get event for your button 'test' like test.Click +=test_Click;
