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?

Solution 1

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

document.getElementById('hdnDeletedRecord').value='DELETE';
document.forms[0].submit();

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.
