.NET Forum / ASP.NET / General / July 2007The best way to validate UserControls
Hi, I have a user control that has a property named "Text" Is there any way that I use a RequiredFieldValidator or CompareValidator to validate my user control's value? I tried it and I received this error: Control 'cboCountry' referenced by the ControlToValidate property of 'valCountry' cannot be validated. Thank you, Max > Hi, > [quoted text clipped - 10 lines] > Thank you, > Max Hi... i assume you have a control inside the usercontrol that receive input from user and you do want to validate the input ... here are the options you have... 1. add the requited field validator for the input in the usercontrol rather that in the page... 2. validate the text using server side validation... (for this you need to write a server side validation method...) Thanks Md. Masudur Rahman (Munna) kaz Software Ltd. www.kaz.com.bd http://munnacs.110mb.com Hi Max, Yes, I agree with Masudur's opinion. Also, if you do want to make Validator controls directly function against your ascx usercontrol, you can use the "ValidationPropertyAttribute" class to define a property to be validatable in your ascx control's code behind. #ValidationPropertyAttribute Class http://msdn2.microsoft.com/en-us/library/system.web.ui.validationpropertyatt ribute(VS.80).aspx Based on my test, through the intellisense not work, you can manually put usercontrol's ID to validateor's "ControlToValidate" property and so far it seems only server-side validation is working in this case. Anyway, I think Masudur's suggested approaches are still the preferred ones here.
