Hi friends,

I have a doubt and in confusion. I am using single master pages and multiple content pages. In this content pages, multiple control i am using in every content pages. In my master page i put treeview . while i click one link in one content page its refresh. For eg.,

frmcontentone ---> Link 1
frmContentTwo---> Link 2
frmMasterPage.Master ---> Tree view, Link1 and Link 2

frmContentOne--> i give set as start page in my application.

While i click Link 2 it goes to frmContentTwo.aspx.At that time my whole page is refreshed. ie First frmContentOne.aspx i click link it goes to frmContentTwo.aspx.

Data loaded in Treeview.Now i click data treeview its nothing happen.Because
the data of treeview is in frmContentOne. How can i solve this problem. I am using updatepanel and put control in the update panel(Master page). Its also
refreshed.

My problem is its affect master page.Please give me any idea or give any useful link for Multiple content pages using update panel and single master page,

Hope ur's reply.
