I have a page for searching when I write my name for example in textbox it will search and display the results in a GridView. I'm using an EntityDataSource with a QueryExtender so I didn't write any code in C#.
The problem is: in the GridView I have a hyperlink when I click it, it will go to another page, ok fine then when I return to the previous page the GridView does not show the results of the search when I was left because of the postback (update panel) it show the whole data from EntityDataSource.
I think I have to use session but I don't know how I can do it, I mean how I can save the GridView in session and how I can retrieve it in page_load.
