  Hi guys,
  
  i am usung a RadMaskedTextBox in my form.i read in some other thread that the required field validator doesn't work with rad controls.
  So i put a custom validator and wrote a ClientValidationFunction
  
   function rad_TimeEnds_Validate(sender, args)
      {
      var picker = $find("<%= txtphone.ClientID %>").GetValue();
  //    (___) ___-____
      if (picker.length == 0)
          args.IsValid = false;
      }
  I am using a ValidatorCalloutExtender in the form. but even after using the custom validator the validator call out extender is not working correctly for the rad masked text box

  Hello Liju,
  
  As far as I know, most of the RadControls supports RequiredFieldValidator.And for some controls, which doesn't supports RequiredFieldValidator, we need to go for Custom validator. However with RadMaskedTextBox we can use the RequiredFieldValidator.Here is the sample code:
  
  aspx:
  

  <telerik:RadMaskedTextBox ID="RadMaskedTextBox1" runat="server" SelectionOnFocus="SelectAll"

              Label="IP address: " PromptChar="_" Width="300px" Mask="###:##">

  </telerik:RadMaskedTextBox>

  <asp:RequiredFieldValidator ID="RequiredFieldValidator1"  ControlToValidate="RadMaskedTextBox1" runat="server" ErrorMessage="RequiredFieldValidator">

  </asp:RequiredFieldValidator>
