Validation before save

[Martin]

I have read every bit of information there is on the RadCollectionNavigator, not much out there, so now I have to ask (-:

I would like to:
- Validate before accepting a new item
- Undo a new item
- Ask fro delete confirmation
- Know how to set focus on the new item in a rad listbox

Can I do this with the RadCollectionNavigator or do I have to find another solution?

Hi Martin,

Currently, such functionality cannot be performed through the API of RadCollectionNavigator. The way add/delete work is to call the corresponding methods of the source collection - AddNew(), Remove(dataItem) and everything is performed on the data layer.
Nevertheless, we will definitely consider exposing events for those functionality.

Hi,

This question was asked long back. Not sure whether these functionalities have been added in later releases or not.

I have similar issues. I want to undo a new item, ask for delete confirmation.... on RadGridView. if these functionalities have been added to RadCollectionNavigator, could you please let me know where can i find them? If its available in MVVM Light, it would be great.

Thanks,

Hi Amit,

The RadCollectionNavigator does not have build-in functionality for Undo/Redo operation. Regarding the delete confirmation. In this case, you can customize RadCollectionNavigator’s commands. More information can be found in the Customizing Commands help article in our documentation. In your case, you can check the MoveCurrentToNext and MoveCurrentToPrevious section which demonstrate how to show confirm dialog before moving to the next item.
