Read up on QueryString, but you can so long try this:
Response.Redirect( "NextPageName.aspx?query1=" + txtBox1.Text + "&query2=" + txtBox2.Text + "&query3=" + txtBox3.Text + " );
//you can attach as many queries in the query string
To retrieve the values from the query string:
String query1 = ( Request.QueryString[ "query1" ] != null ) ? Request.QueryString[ "query1" ] : String.Empty;
String query2 = ( Request.QueryString[ "query2" ] != null ) ? Request.QueryString[ "query2" ] : String.Empty;
String query3 = ( Request.QueryString[ "query3" ] != null ) ? Request.QueryString[ "query3" ] : String.Empty;
Happy Coding,
