Depending on what the Sender is it might work if it can be cast to a TDBGrid. Can you actually run an application with that cast? What is the Sender?
I put a DBGrid and a DBMemo on a form and in the OnShow assigned the DataSource property of each to a DataSource I had also placed on the form. Everything worked as expected. Then I changed the assignment to the DBMemo to the following: TDBGrid(DBMemo1).DataSource := DataSource1; Both a syntax check and a build did not throw any errors but if I attempted to run the application it would error out with an access violation as soon as it got to the above assignment. I think that FPC is just catching it at compile time while Delphi is not.
