How to let Html Link (anchor) do a postback to be like LinkButton?

Question

I would like to ask how can i make an html anchor (a element) or even any object to do a postback or to execute an server side method? I want to create a custom button (a wrapped with some divs to do some custom them) and i want to implement OnClick to be look like the ASP.NET LinkButton?

Like

<a href="#" onclick="RunServerSideMethod()">Just a simple link button</a>

Solution 1

By default, controls use __doPostBack to do the postback to the server. __doPostBack takes the UniqueID of the control (or in HTML, the name property of the HTML element). The second parameter is the name of the command to fire.

So for a custom button, render to the output stream:

<a id="someclientid" name="someuniqueid" href="javascript:void(0);" onclick="__doPostBack('someuniqueid', '');">val</a>

In your custom button, add the IPostBackEventHandler, and this __doPostBack statement will fire its RaisePostBackEvent method automatically for you.

Solution 2

Use a server side html control, HtmlAnchor which is a server side a tag.

<asp:HtmlAnchor runat="server" onclick="RunServerSideMethod">Just a simple link</asp:HtmlAnchor>

Solution 3

Just add on anchor tag --> runat="server" onServerClick="Your function name", it solves your problem.

Solution 4

One workaround could be :
invoke dummyButton click in client side event of anchor tag - which will call server side event of this dummy Button by default. so if u place ur server side code in this dummyButton server event - calling anchor tag client side event would invoke this server side dummy button event.

Code:

<a id="ancLink" href="javascript:void(0);" >back</a>

<asp:Button ID="dummyRefresh" runat="server" OnClick="BtnRefreshOnclick" style="display:none"/>

Javascript:

ancLink.live("click", function () {
         callDummyButtonServerEvent();
    });

function callDummyButtonServerEvent() {

    $('input[id$=dummyRefresh]').click();   

}
