  Cant seem to get the Validations to work

  Mar 19, 2009 02:07 PM | LINK

  I have the following, the datagrid is populated. instead of showing the validation errors, when I run the app, it throws a runtime error with the description I have given. not sure what I am doing wrong. I can see the validations have propagated to client side

  Thanks

  <riaControls:DomainDataSource x:Name="source" LoadSize="30" LoadMethodName="LoadCustomers" AutoLoad="True">

  <riaControls:DomainDataSource.DomainContext>

  <domain:NorthwindContext />

  </riaControls:DomainDataSource.DomainContext>

  </riaControls:DomainDataSource>

   

  <StackPanel>

  <dataControls:DataPager PageSize="10" Source="{Binding Data, ElementName=source}" />

  <data:DataGrid x:Name="datagrid1" ItemsSource="{Binding ElementName=source, Path=Data }" AutoGenerateColumns="false" >

  <data:DataGrid.Columns>

  <data:DataGridTextColumn Header="Customer ID" Binding="{Binding CustomerID}"/>

  <data:DataGridTextColumn Header="CompanyName" Binding="{Binding Path=CompanyName}"/>

  <data:DataGridTextColumn Header="Contact Name" Binding="{Binding ContactName}"/>

  <data:DataGridTextColumn Header="Contact Title" Binding="{Binding ContactTitle}"/>

  </data:DataGrid.Columns>

  </data:DataGrid>

  and the metadata class has properties decorated  like this

  [Required(ErrorMessage = "CompanyName is required!!!!!!!!!!!")]

  public string CompanyName;

  [Required]

  public string ContactName;

  [Required]

  public string ContactTitle;

  public string Country;

  [Required]

  [StringLength(5, MinimumLength=5)]

  public string CustomerID;

  Hi Lee,

  Silverlight 3 uses exceptions to notify the controls when validation has failed and these appear as user-unhandled exceptions when debugging. The exception you are seeing is likely expected. If you continue past the exception(s) or run your application without debugging, you should see the validation visuals. If not, please reply with the exception message and stack.

  Thanks,

  Exception Validation

  Hi Lee,

  Are you running the app in Debug mode, your application will continue if you hit F5. Alternatively, you can run the application by pressing CTRL+F5. Also ensure that the VS is not configured to throw when an exception is encountered.

  Thanks
