I thought I'd found the solution (when I looked at the documentation
again), namely to use the Update & Refresh methods on the controls as
per the code below:
FMain.ValueBoxLatitude.Value = MDatabase.ResultSite!latitude
FMain.DataSourceCountry.Connection = MDatabase.DatabaseConnection
FMain.DataSourceCountry.Table = "country"
FCountryMaintenance.DataSourceCountry.Update()
FCountryMaintenance.DataSourceCountry.Refresh()
FMain.DataBrowserCountry.Columns = ["country"]
FCountryMaintenance.DataBrowserCountry.Update()
FCountryMaintenance.DataBrowserCountry.Refresh()
However, that didn't work. Has anyone got the DataSource & DataBrowser
controls working in conjunction with each other? If so, I'd be grateful
if you could post some details with its associated project attached.
