Validation of two grid boolean columns where one has to be checked

[WenatexIT]

Hi

 

I need a way to validate on my grid that at least one of two checkboxes is checked

 

I think this is not possible with the validation-extension {$.extend(true, kendo.ui.validator ...} method?

 

What would be the best way to achive this?

 

My grid is set to inline-editing

Is it possible to intercept, when the user clicks the save/update - button?

 

kind regards

Hi

 

I found a solution, if there is an more elegant way, you're welcome

 

(($, kendo) =>
{
    var notCheckedMenu1: Boolean = false;

    $.extend(true, kendo.ui.validator, {
        rules: {
            externalOrderValidation(input)
            {
                if (input.is("[name='menu_1_flag']") && input.is("[type='checkbox']"))
                {
                    if (input.prop("checked") === false)
                    {
                        notCheckedMenu1 = true;
                    } else
                    {
                        notCheckedMenu1 = false;
                    }
                }

                if (input.is("[name='menu_2_flag']") && input.is("[type='checkbox']") && input.prop("checked") === false)
                {
                    if (notCheckedMenu1 === true)
                    {
                        input.attr("data-externalOrderValidation-msg", "Bitte ein Menü wählen!");

                        return false;
                    }
                }

                return true;
            }
        },
        messages: {
            externalOrderValidation(input)
            {
                return input.attr("data-val-externalOrderValidation");
            }
        }
    });
})(jQuery, kendo);

 

Kind regards

Hi Florian,

Another option for validating values from multiple columns would be to get reference to the dataItem, using the INPUT element and retrieve the value from the other columns:

var dataItem = $("#grid").data("kendoGrid").dataItem(input.closest("TR"))

Hope this helps.
