RadGridView IDataErrorInfo

[Ravi]

Hi,

I have implemented a hierarchical grid, i want to apply validation on the model class. onLoad of the form i am assigning the datasource which is an observable collection of my model class. now if the user edits the value in the grid of any row or adds a new row i want the validation to be fired and validate the data.

Please do let me know any other mechanism if IDataErrorInfo doesnot support . I am using the latest build of RadGridView (Q1, 2011).

now i need the following validation.
textbox should not be empty
textbox should have a maxLength of 100
and the value which user enters should be checked whether it exists in the collection whcih i already have. (no need of an async call).

Thanks

I am using Silvelight 4 with the latest Telerik build. The site you had suggested is for WPF.

Please advice.
