Question

When you click edit in a grid that is not using a template then the validation rules that you defined for the schema.Model get applied correctly. But if you use a custom template the schema.Model validation rules do not get applied.

I suspect that the answer is that because I am using a custom popup edit template so that I can have a dropdown list, that I have to manually specify the rules for each html input field such as required. I so hope this is not true and that the same rules for defined the schema.Model will also work for an editor template.

Please post if you know the answer, Thanks!

Here is my code for getting the validation attributes defined in the model and adding them to the DOM

/**
 * Sets label,input html5 attributes and css based on the validation attributes of the
 * model for the given dataSource
 * @param {Object} myDs    dataSource that contains the Model Schema used for validation.
 */
function addValidationAttributes(myDs) {

    var myFields
    //Pass in DS or pass in model from grid
    if (myDs.options) {
        myFields = myDS.options.schema.model.fields
    } else//model
    {
        myFields = myDs.fields
    }

    $.each(myFields, function(fieldName) {
        //Add validation attributes
        if (this.validation) {
            $('#' + fieldName).attr(this.validation);
            //Set label to required if field is required
            if (this.validation.required) {
                $('label[for=' + fieldName + ']').addClass('required');
                $('#' + fieldName).attr('title', "required");
                //Check if KendoUI widget because it creates an extra span
                if ($('#' + fieldName).is('[data-role]')) {
                    $('.k-widget').after('<span class="k-invalid-msg" data-for="' + fieldName + '"></span>');
                } else {
                    $('#' + fieldName).after('<span class="k-invalid-msg" data-for="' + fieldName + '"></span>');
                }
            }
        } else//optional
        {
            //Non requried fields set to optional exclude KEY ID STAMP
            if (fieldName !== '__KEY' && fieldName !== '__STAMP' && fieldName !== 'ID') {
                //Check if KendoUI widget because it creates an extra span
                if ($('#' + fieldName).is('[data-role]')) {
                    $('.k-widget').after('<span class="optional" data-for="' + fieldName + '"></span>');
                } else {
                    $('#' + fieldName).after('<span class="optional" data-for="' + fieldName + '"></span>');
                }
            }
        }

    });
}

Also just in case you want it I set a class which adds an * before the label of a required field and a class the adds text “Optional” after each no required field. The KEY, ID, and STAMP are fields defined in my model but I don’t put them on a form, so you can exclude your entity key field or not if you want.

Here they are

.required:before {
    content: "*";
    color: red
}

.optional:after {
    content: " (optional)";
    color: #777;
}

Answer 1

use required in your input elements

<input type="text" class="k-input k-textbox" name="Name" data-bind="value:Name" required>
