    I'm migrating a project based on the telerik MVC extensions, over to Kendo, and I'm having problems with an edit form.

    It's based on a custom object, which uses data annotations for validation, on a couple of decimal fields:-
    [Required(ErrorMessage = "Activity Value is required!")]
           [Range(0, 90000000, ErrorMessage = "Activity Value Cannot be less than zero!")]
           [RegularExpression(@"^\d{1,8}(\.\d{1,4})?$", ErrorMessage = "Please enter a numeric value with up to four decimal places.")]
           public decimal Activity { get; set; }

    When a record is inserted, the regular expression validation error message is shown, even though the data entered meets the criteria. The only way to get the form to work is to comment out the regular expression rule. The range validation works fine.

    This code worked perfectly using the old MVC extensions grid and pop-up edit form. How can I get this to work using the Kendo grid?

    Hello Andrew,

    I confirm that there is issue with the regular expression validation when using the Kendo Grid Wrapper for MVC.
    We are aware of the problem and we are looking for a way to fix it. 
    I am afraid that work-around is not available, however using different editing mode should not cause such behavior. 

    I am sorry for the inconvenience caused.

    Ok, I've managed to get much of the same validation by using a numeric text box.

    However it would be good to get regular expression validation working, as it was with the old MVC extensions.

    Hello Petur, 

     I tried to use regular expression in my view model, which is bound to the grid. Unfortunately, I get an error, if I try to validate using a regular expression: 

         0x800a139a - JavaScript runtime error: Unexpected quantifier

    Is there still a problem with regular expression validation in Telerik/ Kendo Grid Wrapper for MVC? 

    Thanks
     -Ben

    Hi Ben,

    Please note that RegularExpression validation attribute is now fully supported - that why I would suggest to open a new support ticket / forum post and provide more information about your current Model and Grid configuration. This way we will be able to pinpoint the exact reason for current behavior.
