    I have server side business logic validation that throws an exception when validation rules fail. How do I catch this on the client side?

    This is using a RadGridView with a QueryableDataServiceCollectionView data source in an MVVM application. I can see the error message formatted into XML inside the resulting clientside AggregateException, but this exception occurs inside a Telerik DLL and I don't see how/where to catch and handle it.

    Thanks.

    Hello Greg,

    Generally, this depends entirely on your exact implementation and the validation mechanism you are working with. What you can try though is to handle CellValidating/CellValidated events of the grid or RowValidating/RowValidated and verify whether they would be appropriate for your scenario ?

    My team is going to add the business logic project as a reference in the client solution so the rules can be accessed by the client without a trip to the server yet still we only code the business logic in one place.
