i don't managed to get it working. First i tried it with SQLite. After this i tried it with an microsoft access database file (weddingplanner.mdb (from http://www.telerik.com/forums/looking-for-weddingplanner-mdb)
i managed to create a dataconnection in the server explorer (VB2010). When i fill 'datasource' with this dataconnection an dataset (weddingplannerdataset) and bindingsource (weddingplannerdatasetbindingsource) are created. Now i can fill 'linkdatamember' and taskdatamember' with the tablenames. But when i try to fill the other member (p.e. linkstartmember, linktypemember, linkendmember) i see no fieldnames in the dropdownlists.
Because i have the same result with accessdatabase and SQLite database i think i am doing something wrong. I also tried it on an fresh installed version of windows with the same result.
