I can’t wait to migrate my apps to ASP.NET MVC but until i have the time to do that i have to coup with some of asp.net strange parts.

Today i wanted to invoke a postback via JQuery wich actually was fairly easy but i wanted to write a small post about it.

The trick was to get the Javascript that asp.net call to do a postback, save it somewhere and then executed via the eval() method. I used a hidden form to store the postback script.

In the asp.net file

hdnSearchPostBack.Value = Page.ClientScript.GetPostBackEventReference(SearchButton, string.Empty);

In the js file

function() { eval($("#ctl00_ctl00_hdnSearchPostBack").val()); }

Simple as that!
