Hello Mentors,

Could anybody tell me how can i use __dopostback method to call the codebehind of another page.

I want to override the __dopostback so that i could change the value of theform and set it equal to the form for which i want to call the _postback.

this is what does automatically---

var theForm = document.forms['Form1'];
if (!theForm) {
    theForm = document.Form1;
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;

i want to set the theForm =window.parent.self.firstGrid.document.Form1;

as i want to call the code behind of Form1 which is another aspx.

This sounds like a bad idea. Maybe you can explain why you want to do this and we can figure out a more proper way to do what you need.

The issue is that..i have 2 pages.One is header page and another aspx page which i am using to load the Gridview.
I want to delete the GridView rows on click of a button placed on Header page.

Now the issue is that i am using Datatable.rows.removeat(Index) to remove a row from the gridview without a postback.

As both the pages are different so on click of a button on header page is not refreshing the Grid on another page.For that i am calling

__doPostBack('InboxGrid', 'Delete$0')

from the Header page. Kindly suggest the alternate if any.

Thanks All,

Its working fine now.

default__doPostBack = __doPostBack;

   var theForm = window.parent.self.firstGrid.document.Form1;
