I recently modified some old UI code using Delphi’s VCL to use ADO instead of BDE. One of the screens used a TDBGrid control to modify the underlying DataSource, but it appears that is no longer possible to edit the values in the grid. Here is how I have it configured:

TDBGrid->TDataSource->TADOTable

I found this post on another forum that seemed related:

Is this a limitation of ADO? Or do I simply need to change the settings of a control somewhere? (cursor type or something?)

    Okay, I solved the problem. When I converted the project from Delphi 6 to Delphi 2007, it changed the Options property of the TDBGrid control to seemingly random values (perhaps some defaults?). In this case, the dgEditing option was set to false.
