Binding Data To Rad Controls With Ria Domain Data Source and Validation Issue

[Ahmed]

I have Rad Masked Text Box and I bind it with RIA Domain Data Source

<riaControls:DomainDataSource AutoLoad="True" d:DesignData="{d:DesignInstance my:User_Skill, CreateList=true}" Height="0" LoadedData="user_SkillDomainDataSource_LoadedData" Name="user_SkillDomainDataSource" QueryName="GetUser_SkillByIDQuery" Width="0">
    <riaControls:DomainDataSource.DomainContext>
        <my1:DomainServiceClass />
    </riaControls:DomainDataSource.DomainContext>
</riaControls:DomainDataSource>

and The Rad Masked Text Box Code

<telerik:RadMaskedTextBox HorizontalAlignment="Left" Margin="92,235,0,0" Name="skill_nameRadMaskedTextBox" VerticalAlignment="Top" Width="197" Value="{Binding Path=skill_name, Mode=TwoWay,ValidatesOnNotifyDataErrors=True}" MaskType="None" MaskedText="" />

The Problem is When I Create New Object Like That in RIA Doamin Data Source

(user_SkillDomainDataSource.DataView as IEditableCollectionView).AddNew();

 

After That when The New Created Object Passed To Controls The Error Notification for Required Proberties Appear Immediatly Before Doing Any Thing ........ I don't Want That I want The Notifcation Disapled Until I start Working With Controls ........ Moving Between Controls or When The Controls Lost Focus

Hello Ahmed,

The RadMaskedTextBox binds directly to the Validation.Errors attached property and retrieves the errors. Currently, there is no way to delay this process and have validation at the same time. What you could do is to bind the RadMaskedTextBox and activate the validation when you start working with the controls.

Kind regards,

Hi Ahmed,

In this scenario, I believe there is no straight forward solution for this. You can try providing your custom validation tooltip if you want to achieve this specific logic. Please also note, that for the upcoming Q1 2011, we are refactoring the RadMaskedTextBox control. We are going to make some changes around the validation.

We could also provide an out-of-the-box way to turn on and off the validation tooltip at any time. I added it as a feature request and you can vote for it in our PITS thus increasing its priority. 


All the best,
