enable postback onclick of a hyperlink in asp.net

Question

I have a hyperlink as

<a href="" id="link1">Click</a>

I have do enable a post back action whenever this link is clicked.

We can do

<a href="" id="link1" onclick="javascript:location.reload()">Click</a>

However, I want to do a page postback and not a page reload.

Is it possible?

You shouldn't be doing this, `` elements should be links for GET resources, not for POST form submission. — Dai, Mar 26 '13 at 23:14

Simple, use a LinkButton instead.

void LinkButton_Click(Object sender, EventArgs e) 
{
   Label1.Text="This is a postback";
}

on aspx:

  <asp:LinkButton id="LinkButton1" 
       Text="Click Me" 
       OnClick="LinkButton_Click" 
       runat="server"/>

You are using a html link, if you want to use serverside code i would suggest to use server controls. However, if you reallly insist you could call __doPostBack manually via javascript.

<a id="linkId"  href="javascript:void(0);" onclick="__doPostBack('linkId', '');">click me</a>

Is there a way I can do it using the hyperlink. The existing system already has a hyperlink and I don't want to change that to a Link Button – user544079 Mar 26 '13 at 23:18
