Validation in enterprise Library

[Arif]

 

 

 

Hi all,
i have applied validation in a text box as follows. note i m using enterprise library for validation purpose:

<TextBox Grid.Row="3" Grid.Column="1" TabIndex="2" Margin="5" MinHeight="40" TextWrapping="Wrap" AcceptsReturn="True" VerticalScrollBarVisibility="Visible" >

 

 

 

 

<Binding Path="Vehicle.Comments" UpdateSourceTrigger="PropertyChanged" ValidatesOnDataErrors="True" Mode="TwoWay" >

 

 

 

 

<Binding.ValidationRules>

 

 

 

 

<y:ValidatorRule SourcePropertyName="Comments" SourceType="{x:Type e:tblVehicle}"/>

 

 

 

 

</Binding.ValidationRules>

 

 

 

 

</Binding>

 

 

 

 

</TextBox>

now i want to apply it at RadDatePicker:

 

 

 

 

<telerik:RadDatePicker TabIndex="8" ToolTip="Enter due date ..." Name="dtpDueDate" Height="25"

 

 

 

Background="Transparent" BorderBrush="{DynamicResource brushWatermarkBorder}" >

 

 

 

 

<telerik:RadDatePicker.SelectedDate>

 

 

 

 

 

 

 

 

 

</telerik:RadDatePicker.SelectedDate>

 

 

 

 

 

　

 

 

 

 

 

 

</telerik:RadDatePicker>
it give me nothing under .selectedDate property.

how can i apply the validation rule in a pattern as applied at textbox in the datepicker?

Thanks.

Hello Arif,

You can use the same approach as the TextBox text property validation. Just note that the return type must be of DateTime, the same as the SelectedDate type property.
