Answer : goto aspx page based on id value

if you are using C#, try

int ID = Convert.ToInt32(Page.Request.QueryString["ID"]);

or

int ID = Convert.ToInt32(Page.Request.QueryString[0]);

or if you are using VB.NET, try

Dim ID as Integer = CInt(Page.Request.QueryString("ID");

or
Dim ID as Integer = CInt(Page.Request.QueryString(0);

Then you can just use ID variable in your code
