I am using Grid MVVM InCell Editing and i want the column "AmountCurrency" to be editable based on bool value "IsUserCreated" (true/false). And i want to add css class "Red" to column "CountryCode" . How can i do that?

Hi, Neeraj,

To achieve the desired conditional editable state of the AmountCurrency column, you may use "columns.editable" setting as a function:

'editable' : function(dataItem){ return dataItem.IsUserCreated; }

Here is an example of that :

http://dojo.telerik.com/IfIZaYAL

As for adding a class to a specific column, you may use the columns.template:

'template': '<span class=\'red\'>#=CountryCode#</span>'

I have added another column 'Amount' in grid. The editor doesnt work as expected :

<script id="test" type="text/x-kendo-template" >

<div data-role="grid" id="ImportPnrSupplierTaxGrid"

                data-editable='true'

                data-columns='[{ "field": "ID",hidden: true },

                { "field": "IsUserCreated", hidden: true },

                { "field": "OfficePNRTSTID", hidden: true },

                { "field": "CountryCode", "title": "Code","attributes": { "class": "focusedCell" }},

                { "field": "Type", "title": "Sub Code", width: 80 },

                { "field": "Description", "title": "Description", width: 250},

                { "field": "AmountCurrency", "title": "Currency", width: 80 , editable: false },

                { "field": "Amount", width: 70, "footerTemplate": kendo.template($("\\#ImportPnrSupplierTaxGridAmountFooter").html()), "editor": "ImportPnrSupplierTaxGridAmountEditor" ,"editable" : function(dataItem){ return dataItem.IsUserCreated; } },

                 { "field": "IsGST", width: 60, "title": "IsGST", template: kendo.template($("\\#ImportPnrSupplierTaxGridIsGST").html()) },

                { command: [{ name: "destroy" }], width: 90,visible: function(dataItem){ return dataItem.IsUserCreated; } }

                ]'

                data-bind='source: Tax.TaxBreakup,events: {dataBound: ImportPnrSupplierTaxGridDataBound}'

                style="height: 200px"></div>

</script>



//function inside viewmodel

ImportPnrSupplierTaxGridAmountEditor: function(container, options) {

            debugger;

            $('<input data-bind="value: ' + options.field + '" />')

                .appendTo(container)

                .kendoNumericTextBox({

                    spinners: false,

                    attributes: { style: "text-align:right" },

                    change: function (e) {

                        debugger;

                        var total = 0;

                        var griddata = $("#ImportPnrSupplierTaxGrid").data().kendoGrid.dataSource.data();

                        for (i = 0; i < griddata.length; i++) {

                            total = total + parseFloat(griddata[i].Amount != undefined ? griddata[i].Amount : 0);

                        }

                        $("#ImportPnrSupplierTaxGrid tbody tr div.TaxGridFooter").text(total.toFixed(2));

                    }

                });

        },

When we click on Amount , the name of function displayes as text . there should be kendoNumericTextbox as specified in Editor

for nested property which has array , we should assign like this:

VM.set("SelectedFareFamily.PricingCommercialSkeleton.SupplierCommercials.SupplierHeads.Tax.TaxBreakup",$(source).data("kendoGrid").dataSource.data());

OR

VM.SelectedFareFamily.PricingCommercialSkeleton.SupplierCommercials.SupplierHeads.Tax.TaxBreakup = $(source).data("kendoGrid").dataSource.data()

Hi, Neeraj,

Please find the answers to your questions below:

1) When we click on Amount , the name of function displayes as text . there should be kendoNumericTextbox as specified in Editor

This is expected as the name of the function is passed as a string, not the function itself. You may declare it as a standalone function and pass the name to the "columns.editor" property minus the quotes:

function ImportPnrSupplierTaxGridAmountEditor(container, options) {}

{ "field": "Amount", width: 70, "editor": ImportPnrSupplierTaxGridAmountEditor ,"editable" : function(dataItem){ return dataItem.IsUserCreated; } },

Alternatively, if you wish to keep it in the viewModel, then you should get it out of it when needed with a get() or directly:

'editor': viewModel.ImportPnrSupplierTaxGridAmountEditor

'editor': viewModel.get('ImportPnrSupplierTaxGridAmountEditor')

2) How to set nested properties

In order for the observable to trigger change, you should use the set() method. I tested setting in the following two ways and they both work as expected:

this.nested.nestedOne.nestedTwo.nestedThree.nestedFour.set("nestedFive", this.get("name"))

this.set("nested.nestedOne.nestedTwo.nestedThree.nestedFour.nestedFive", this.get("name"))

In my case, all of the nested fields are observable objects and you can see that by inspecting their prototype, so any combination of setting works well.

Here is a Dojo that I tested for both of the questions above:
