DataSource Controls :: Using LINQ Passing The Name Of The Stored Procedure Dynamically?

I have an application where depending on what the user selects run a different stored procedure.

I am using LINQ and am passing the stored procedure name into a sub that will run the stored procedure and return values that I am loading into a DDL.

For example I want to pass the procedure name "GetProducts_Hats" to the sub and not hardcode it.

Protected Sub LoadParamDropDowns(
ByVal SqlObjToExec
As
String )

I am passing the storedprocedure name in parameter SqlObjToExec

so instead of

values = mydb.GetProducts_Hats

I want to code it to be a variable

values = mydb.SqlObjToExec

But the above code does not work.
