Edit Mode for the new added row

[Raffaele]

I just upgrading from Q3 2010 to Q1 2011 of Silverlight Controls and I saw an unexpected behavior for the RadGridView.

I use the GridView in a MVVM application and when I add an element to the ObservableCollection in binding to the RadGridView, in the Q3 2010 version the new item goes automatically in edit mode. Now, with the Q1 2011 version, it doesn't go in edit mode and I am problem to switch in edit mode because my application is a pure MVVM and doesn't have code behind to call the BeginEdit method.

Can you confirm that you changed this behavior in the latest version? Can you help me?

Hello Raffaele,

RadGridView doesn't behave this way. I've just tested with 2010.Q3 assemblies and all I get while adding new item to an ObservableCollection<T> is just another row in the grid.
In order to bring an item into edit mode you should call BeginEdit(), but this requires some custom code.
Could you please provide with a little bit more information about your project?

When I add a new row, the new object added to the collection is not valid because one property is empty and it's required. So I need that the RadGridView goes in edit mode to allow the inserting of a valid value. This is a problem because the GridView doesn't recognize the property as invalid when I add a new object, so also if I set BeginEdit(), it allow me to undo the edit mode using ESC key and returning to an invalid value (empty) for my property.

Hello Raffaele,

Could you please provide me with a little bit more info about your project?
I need more info about how do you perform the validation and how do you add the new item.
Thank you in advance.
