Hi telerik team!
I meet with problem when use RadMaskCurrencyInput
XAML:

<Grid x:Name="LayoutRoot" Background="White" BindingValidationError="LayoutRoot_BindingValidationError" >
  <sdk:RadMaskedCurrencyInput x:Name="maskInput" Mask="c3.0" Value="{Binding Cost,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}" />                        
</Grid>

When RadMaskedCurrencyInput binding error Debugger don't run into LayoutRoot_BindingValidationError which handle BindingValidationError event of LayoutRoot. Please give me a solution to resolve this problem.
Thanks !

Hello Umbala,

I tested this with the release version of Q1 and this worked correctly. The parent Grid panel is handling the BindingValidationError event as expected. Can you confirm that your binding is not failing and that you are correctly raising the validation exception.

Please try to run my code
XAML:
<Grid x:Name="LayoutRoot" Background="White" BindingValidationError="LayoutRoot_BindingValidationError" >
       <Grid.RowDefinitions>
           <RowDefinition Height="Auto"/>
           <RowDefinition Height="Auto"/>
       </Grid.RowDefinitions>
       <Grid.ColumnDefinitions>
           <ColumnDefinition Width="Auto"/>
           <ColumnDefinition Width="Auto"/>
           <ColumnDefinition Width="Auto"/>
       </Grid.ColumnDefinitions>
       <TextBlock Text="{Binding OrderName}" Grid.Column="0" Margin="8"/>
       <sdk:RadMaskedCurrencyInput x:Name="maskInput"  Mask="c3.0" Grid.Column="1" Value="{Binding Cost,Mode=TwoWay,ValidatesOnExceptions=True,NotifyOnValidationError=True}" Margin="8"/>                        
   </Grid>
Code:
Imports System.ComponentModel.DataAnnotations
  
Partial Public Class MainPage
    Inherits UserControl 
  
    Public Sub New()
        InitializeComponent()
        Me.DataContext = New Order("Order1", Nothing)
    End Sub
  
    Private Sub LayoutRoot_BindingValidationError(sender As System.Object, e As System.Windows.Controls.ValidationErrorEventArgs)
        MessageBox.Show(e.Error.ToString)        
    End Sub
  
End Class
  
Public Class Order
    Public Sub New(ByVal strOrderName As String, dCost As Double)
        Me.OrderName = strOrderName
        Me.Cost = dCost

Hello Umbala,

I am not sure if the data annotation attributes will raise the BindingValidationError event. What you can try is to throw a ValidationException in the setter of the bound property.

private double cost;
public double Cost
{
    get { return cost; }
    set
    {
        if (value > 50)
        {
            throw new ValidationException("Cost cannot be greater than 50");
        }
        cost = value;
        this.OnPropertyChanged("Cost");
    }
}

If using RadMaskTextbox instead of using RadMaskCurrencyInput every thing work fine.
My project is using data annotation attributes to validate data and I can't change this mechanism. Please show me how to handles BindingValidationError event  if using data annotation attributes  to validate data because all of entity in my project inherit from System.ServiceModel.DomainServices.Client.Entity   and use ValidateProperty() of System.ServiceModel.DomainServices.Client.Entity  method to validate data

Public Class Order
    Inherits System.ServiceModel.DomainServices.Client.Entity
   
    Public Sub New(dCost As Double)        
        Me.Cost = dCost
    End Sub
 
    Private m_Cost As Double
    <Range(1, 5, ErrorMessage:="invalid")> _
    Public Property Cost() As Double
        Get
            Return m_Cost
        End Get
        Set(ByVal Value As Double)
            If Value <> Nothing Then
                Me.ValidateProperty("Cost", Value)
                m_Cost = Value
            End If
        End Set
    End Property
