Have a Sql datasource named "sqldata" and a ODBC datasource named "CEdata" definded in web.config
"Sqldata" contains table "TimesheetHeader" with the fields: ID, Jobnum, Date
"CEdata" contains table "jcjob" with the fields: Jobnumber, Jobname
I want a gridview to list The ID (from sqldata.TimesheetHeader) , Date (from sqldata.TimesheetHeader) and jobname ( from the CEdata.jcjob datasource based on common "Jobnum" key)
I've tried with VS designer, but it seems it will only give me access to one datasource. I'm thinking perhaps there is some way in VB to join the two into one?
So, How can I join the two datasets together via the common "jobnum" key and report results?

Var commanDate =(from d1 in Dt1.AsEnumerable()
from d2 in Dt2.AsEnumerable()
where d1["JobNum"]==d2["JobNumber"]
select new {
JobName=d2["JobName"],
JobNum=d1["JobNum"]
} ).ToList();
Gridview1.DataSource=commanDate ;
Gridview1.DataBind();
Thanks for all your help everyone. FYI, after much research, turns out I can add through Managment Studio to the sql Database a "Remote Server" which can be an ODBC database. I can then create a view and join the databases by refering to the dataset via:
"Remoteservername...dataset". Works fantastic!

You can get the two data into a datatable and use linq to join the datatable. Bind the result datasource in the gridview
some linq examples

Hi UCBearcat,
Based on my understanding,If you are using EF context ,so it does not support cross database queries. While if not ,you can refer to the links below:
http://stackoverflow.com/questions/352949/linq-across-multiple-databases

Hi ,
Make use of Linq
Your query will be like this
Var commanDate =(from d1 in Dt1.AsEnumerable() from d2 in Dt2.AsEnumerable() where d1["JobNum"]==d2["JobNumber"] select new { JobName=d2["JobName"], JobNum=d1["JobNum"] } ).ToList(); Gridview1.DataSource=commanDate ; Gridview1.DataBind();Jointablesfromtwodatasources
