Thank you for writing.
Currently, RadForm does not support such Drag Once DataBinding functionality. Nevertheless what this feature does is to insert a default .NET grid along with BindingNavigator to your form. If you examine our grid you will notice that it is far more advanced and in the general case you do not need a BindingNavigator, because the grid has built-in functionality for adding, removing and navigating and so on. Also when you select the DataSource for the grid using its SmartTag for example all the needed components are automatically created for you (like in the drag once functionality). More information about this is available in the following article: Tutorial: Binding to DataTable or DataSet
Nevertheless if you want you can just drag and drop bindingnavigator
or data entry
and use them along with the grid's binding source.
I hope this helps. Should you have any other questions do not hesitate to ask.
