How do I make a cell required when working with the inline editor?

[John]

Sorry for the stupid question...The demos don't have any code...Working with MVC3 razor. Thanks.

Hi John,


You could define a property as required in the model definition with the DataAnnotations required attribute. Additional information can be found on the following msdn page.
E.g.

[Required]
[DisplayName("Unit price")]
[DataType(DataType.Currency)]
[Range(0, int.MaxValue)]
public decimal? UnitPrice { get; set; }

 

All the best,

Thank you for the reply.

What is the connection between data annotations and the field required popups that I see on the inline editing example at http://demos.kendoui.com/web/grid/editing-inline.html ?

That is the functionality that I would like to replicate. 

Thank you.

Hi John,


The Grid is translating unobtrusive attributes to Kendo validator rules. To achieve this in an MVC Grid, you should use the approach from my previous post. To achieve it in a Web Grid, you should specify it in the model.
E.g.

schema: {
    model: {
        id: "ProductID",
        fields: {
            ProductID: { editable: false, nullable: true },
            ProductName: { validation: { required: true } },
            UnitPrice: { type: "number", validation: { required: true, min: 1} },
        }
    }
}

 

Kind regards,

I did use the approach (for the MVC grid) in your previous post. 

It sort of works in the sense that ModelState.IsValid is false when the call to my controller is made.

However, I am still trying to figure out what makes the client side validation bubbles appear in your example that I referenced.  Can you please help me with that? 

Thanks!

Dimiter:

Thank you again for your help.

To recap what's happening now, if I edit a row in my kendogrid and click in/out of a required cell, the tooltip validator displays.  However, if I press the "update" button on the row, the validators do not run and the row is submitted.  

Basically, I'm trying to figure out how to make the validators display AND cancel the update/save (leaving the row I am editing expanded). 

Any thoughts?

Hello John,


Basically what you are trying to achieve is the expected behavior when using validation attributes. I am not aware of the current implementation of the Grid, so I prepared a sample project for you, demonstrating how to achieve this. Please take a look at it and let me know if it covers the current scenario.

Wish you a great day!
