Required Field validation for a Rad Window

[Manshu]

I have a telerik radwindow(using content template) which shows up on click of a button .There are option Yes and No which user should select.
If the user selects Yes they are directed to another telerik rad window.
How do I make a radio button (With Yes/No options) mandatory for a rad window with content template
Either on close I always reopen the window using javascript but If I do that I am not able to disable the background of the parent window or any other solution?
Thanks,

Hello Manshu,

I can offer a few ideas that can help get you started with implementing your validation logic:

• consider calling the built-in ASP validation through JavaScript and cancelling the button click according to the result. You can see an example here: http://www.telerik.com/help/aspnet-ajax/button-validation-with-postback-confirm.html.
• consider requesting a confirmation from the user or executing your validation logic in the OnClientBeforeClose event so you can cancel it according to your needs: http://www.telerik.com/help/aspnet-ajax/window-application-confirm-closing.html.

These are the two easiest ways to plug your custom validation needs into our controls in this scenario.
