Hi,

Since .Net4.5 the INotifyDataErrorInfo interface is part of WPF. I'd like to use it to validate my TypedView. I used the designer to generate Required attributes for my TypedView. [Required(ErrorMessage="blabla")]

public System.Double Coeff1 
{
    get { return IsCoeff1Null() ? (System.Double)TypeDefaultValue.GetDefaultValue(typeof(System.Double)) : (System.Double)this[_parent.Coeff1Column]; }
    set { this[_parent.Coeff1Column] = value; }
}

I wonder if you had a sample application using INotifyDataErrorInfo with TypedView and Entities ?

thanks

Please check the following thread on IDataErrorInfo: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=21657

In general for other unimplemented interfaces, you may write your own templates to generate the implementation for Entities and TypedViews.

Do the TypedViews support IDataErrorInfo interface ?

TypedViews are readonly DataTable deriving classes, so everything the datatable supports is supported by tyedviews. As datatables are bound through their dataview objects, and rows are bound through DataRowView classes, IDataErrorInfo is supported as it's implemented by DataRowView
