I have an UltraWebGrid with a list of members along with their information. I have the following code in the click event of the grid:

Response.Redirect("Mbrs.aspx?Mbr_ID=" & e.Row.Cells.FromKey("Mbr_ID").Value)

So, when the user clicks on a specific row, the page redirects to itself and passes the Mbr_ID as a QueryString. I know this is not the best way to do this, but I don't know how to do it any other way. The problem is that the table itself has a lot of rows in it, but I only bring in 50 at a time...but when the user selects a row and the page redirects, it seems to be taking a long time to load again. I use the Mbr_ID that the user selected throughout the rest of the application as they are entering other data for the specific Mbr. How can I go about allowing the user to select a row and keep a global variable that keeps up with the mbr that the user has selected until they select a different mbr?

Also, don't know if it makes a difference...but I am using a Master Page.
