refresh page on button click in child page without closing child page

refresh page on button click in child page without closing child page

Dear all,

I have a.aspx page which has a tab container (tab container has 6 tabs, and each tab is associated to different user controls  which means a.aspx has references of pages 1.ascx,2.ascx,3.ascx, 4.ascx,5.ascx and 6.ascx)

5th tab (i.e 5.ascx) has a grid view and on the grid view I have a link button.

On click of the link button, I am opening another .aspx page (i.e b.aspx) as a  JQuery Modal popup page

b.aspx has a tab container ( this tab container has 3 tabs, and each tab is associated to different  user controls which mean b.aspx has references of pages p.ascx, q.ascx and r.ascx)

My requirement is given below

p.ascx (attached to b.aspx) has a next button.

On click of the next button, I want to refresh the grid view or post back the whole page , placed in 5.ascx of a.aspx. I DON’T WANT TO CLOSE THE b.aspx PAGE. THAT PAGE SHOULD REMAIN OPEN.

How can I do this?

Please note b.aspx is open as a JQuery Modal Popup.

Hope my explanation is very clear to you all.. Kindly help me as the project dead line is nearing.

Thanks in advance

Nick
