I have just installed TMS IWC and have tried my first TIWDBADVGrid attempt:
Created a new Intraweb 15 IWform, added an ADOConnection pointing to a local SQLExpress database, added an ADOQuery, set it's sql property to the select * from xxx and added a standard Datasourse and an TmIWDBAdvGrid. Put it all together, compile/run, no errora but the grid is empty. Adding a IWDBGrid, set it to the same datasource, compile and run: the intraweb DBGrid show the records.
So DBGrid for Intraweb 15 do show records, whereas IWDBAdvGrid from TMS do not. What am I missing ?
