I need to redirect a page with parameters
response.redirect("default.aspx?id=" + xmlfile value)

i have been calling parameters from an xml file and this need to be worked only once (i.e!ispostback) event)

so it will be going to directly to the second page without loading the first

but when i use response.redirect in page load event, it returning an error

{Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}

else if (!IsPostBack)

Session["PageToLoad"] = "rlSearch";

Response.Redirect("default.aspx");

thankzzzzzzz
