Hello Mentors,

I am trying to call a code behind function of another page from javascript of my page using _dopostback.

But its not calling.

I tried calling the load event of that page also even that is not being fired.

__doPostBack(window.parent.frames["firstGrid"].document.getElementById('InboxGrid').id, '');

please tell me where i am wrong?

doPostback with TWO underscores, right?

__dopostback - right
_dopostback - wrong

Please confirm.

Use XMLHTTPRequest Concept to delete the record in another page.

XMLHTTPRequest example[^]

After deleting the record, refresh the current page by using script as follows,before this save one temp variable in hidden variable as


In aspx.cs page

check this variable and if hidden variable contains 'DELETE' then reload the grid.

Thanks a lot sanjeev.I have already tried that but the issue is that i am deleting the records from a grid that is present on another page.If i use xmlhttprequest,it deletes the records but i cant refresh the gridview to get the updated data without a postback or reloading.I am using removeat function for that .So i want to call the same using __dopostback.
