The DataGrid object is bound to a data source in the designer. But I have also tried explicitly setting the DataSource property again in that event handler, which didn't change anything. The strange thing is, if after I get this empty DataGrid, I click the button that gets me the data in the first place, I get the original DataGrid, with the appropriate row in edit mode!
But that seems inherintly wrong, that I need to try to get the data again, before I can edit... You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
