What I can't get to work is the Form that's driven off of the data table control. My Item property there is DataTable1.Selected and I receive an error there on the .Selected portion which says "Expected a value compatible with 'DataSource'". My DataSource is '[dbo].[TableName]. I've tried changing it to be the same as the above AddColumns, no difference.
Which step am I missing? Has anyone used data table control with addcolumns and selected a row, then navigated/populated an edit screen?
The reason is that by adding the column, the datasource is not exactly the same in the DataTable and the Form, thus the Selected property must be more specific. Use a Lookup in your Form Item property, IE. Lookup(DataSource,ID=DataTableX.Selected.ID). I hope this works for you.
