Question

Warning – new to Silverlight / RIA Services / etc.

I have a business requirement to show a DataForm with a single record. In nearly all the examples on the net the dataform is tied to a datagrid on the selecteditem property.

In my case, the form has no grid to tie to.

I know that I’m retrieving data with my ViewModel, but I need a call back to know when the data has arrived in order for the data form to “re-bind” (Winform speak!). I am also NOT using the DomainDataSource, as I would like to keep everything behind the ViewModel.

I created a CurrentXXXX property, which can only be set after the data arrives.

There is a IsLoading property, but when do you know that data has arrived in the ViewModel? How do you get the View to rebind?

Answer 1

If your VM implements INotifyPropertyChanged (which it should) then you don’t need to rebind as the VM will use this to notify the View that it’s changed.
