Why are you using  Request.Params["HealthPlanID"];


Shouldn't it be  

Session["HealthPlanID"];

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The quetion is how Do I pass data or why is this not working.  When I try
Session["HealthPlanID"] 

Open in new window

I get the following error


Compilation Error

This:

Session["HealthPlanID"].ToString()

Open in new window


is the proper way to deal with:  "Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)." I should point out, however, that if the "thing" being stored in the "HealthPlanID" is actuall a null reference, then you are going to get an exception when the runtime tries to execute ToString. Be sure to add error checking to that bit of code.

Did you take note of ged325's comment ( http:#a37729308 )?

Your ASP and ASPX are in the same project?

I can't see in your ASP code anything about assigning a value for your HealthPlanID session variable... first of all, if you are not passing values from ASP to ASPX and vice versa, why do you send both codes?

I can't see the relationship... where do you set the HealthPlanID value?
