[xie]

HI! Every one:
 When i use telerikGridView:RadGridView and i used the template on GridViewDataColumn as fllows

<telerikGridView:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding PropertyName, Mode=TwoWay}"/>

</DataTemplate>

</telerikGridView:GridViewDataColumn.CellTemplate>

<telerikGridView:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<TextBox Text="{Binding PropertyName, Mode=TwoWay, ValidatesOnExceptions=true, NotifyOnValidationError=true}" />

</DataTemplate>

</telerikGridView:GridViewDataColumn.CellEditTemplate>

that i need use silverlight validation on fileds, and i throws Exception at set method

public string PropertyName
{
    get
     {
      return this.propertyName;
     }

     set
     {
       if (value == null || value == string.Empty)
       {
           throw new Exception("Property Name is Blank！");
       }
       else if (ValidatorUtil.HasSpecialChar(value, "~!@#$%^&*().,;"))
       {
           throw new Exception("Property Name have special char!");
       }
       this.propertyName = value;
     }
}

why update the propertyname blank and exception touch off, the UI is not prompt?

Hi xie,

 Could you please try throwing ValidationException, and not just the regular Exception?
