Question

Main page has a gridview with options to filter / search etc…

when a user selects a row a NEW page comes up (response.redirect) and i can edit/insert/delete there…

I want the user to be able to go back to the page he came (easy) BUT i want the grid to have the filters as they where on the time of the first redirect.

anything ready in .net or i have to use lets say querystring back and forth to do it?

Answer 1

Avoid using Response.Redirect

Instead of using Response.Redirect, use Server.Transfer where ever you can. Response.Redirect sends response to the client which then sends a new request to the server. Server.Transfer however performs the redirect on the server. Only use Response.Redirect when you want authentication and authorization to be performed on redirects or you want URL on client browser to be changed because Server.Transfer will not do this as it is a server side transfer.

This way you’ll be able to preserve the prvious page folrms collections..
