Is it possible to have multiple validator initializations on different div tags?  Basically I'm wanting to do a wizard (without the use of the progress bar) and I want to validate one div tag per "next" button.

    function ShowSection2()
    {
        //validation
        var validator = $("#Section1").kendoValidator().data("kendoValidator");
        if (!validator.validate())
        {
            return;
        ...

    function ShowSection3()
    {
        //validation
        var validator = $("#Section2").kendoValidator().data("kendoValidator");
        if (!validator.validate())
        {
            return;
        ...

I need to bind to the select event using MVVM in order to prevent some nodes from being selected. I've modified the MVVM demo code to bind to the select event and I'm unable to get it working. Is this a known issue? Is there a workaround that I can use which uses MVVM?

Thanks

Hello,

I am trying to do the following: I copy some data from one TreeView to another They share a DataSource and essentially all I do is set value A to value B, while TreeView1 displays A and TreeView2 displays B.

My steps are:

1) I expand all nodes (loadOnDemand is true so the initial page load doesn't take too long).

2) After the expand is done I copy said data and

3) update the treeView by using node.load() 

(as recommended in this older thread: https://www.telerik.com/forums/force-reload-of-child-nodes#QqLTmHiNQkGQTnhxA2hLSA)

Now, this is working as expected, but as soon as the DataSource gets a bit bigger it gets really slow. My test Data has about 200 items in 3 layers and in IE it takes about 50s for the "node.load()" alone to finish. (Chrome is a lot better with about 5s, but unfortunately I have to use IE.)

I tried a lot of other ways to refresh or reload the TreeViews, but sadly nothing worked for me. I can't read the DataSource again, since my edits are only client-side at this point. A setDataSource() made no changes, as well as simply setting the DataSource (not that the last one is unexpected, but I was getting desperate...)

Does anyone here have a solution for me? Maybe I'm missing something really obvious?

Thanks!

Hello. I'm been dealing with a problem when using conditional formatting. I've created a dojo to explain my problem.

https://dojo.telerik.com/UNoCUfiL/2

TL;DR of my problem: I have to use this format: "[<-10][RED]##,##0.00\%;[>10][RED]##,##0.00\%;##,##0.00\%". Everytime my cell value is < 10 ([<-10][RED]) or > 10 ([>10][RED]), it loses the negative sign. I can't write any rule based on the value 10, because it will change programmatically.. I'm just giving an example with the value 10.

Thank you!

Have a Grid.cshtml page which has one dropdown which is defined by a EditorTemplateName named ValueViewTemplate.cshtml (below).... Would like to add more dropdowns to the Grid.cshmtl.  Currently seems like have to add more EditorTemplateName templates for each dropdown.  Is there way to pass in the ViewData to the EditorTemplateName function so don't have to define a editor template for each dropdown?

Also current pages seems to work for InCell and InLine... Is there way to make it work for Popup for does there need to be additional templates defined for the Popup option for editable mode...

Grid.cshtml

@(Html.Kendo().Grid<NEP_Deconstruction.Data.Models.ApprovalViewModel>()
                .Name("approval_grid")
                .Columns(columns =>
                {
                    columns.Bound(o => o.ApprovalNumber);
                    columns.Bound(o => o.ApprovalName);
                    columns.Bound(o => o.Comment);
                    columns.ForeignKey(o => o.ApprovalCountryID, (System.Collections.IEnumerable)ViewData["ApprovalCountry"], "ID", "Value")
                    .EditorTemplateName("ValueViewTemplate");
                    columns.Bound(o => o.EffectiveDate);
                    columns.Command(command => { command.Edit(); command.Destroy(); }).Width(210);
                })

                .ToolBar(toolbar => toolbar.Create())
                .Editable(editable => editable.Mode(GridEditMode.InLine))

ValueViewTemplate.cshtml

@model NEP_Deconstruction.Data.Models.ValueViewModel

@(Html.Kendo().DropDownListFor(m => m)
                .DataValueField("ID")
                .DataTextField("Value")
                .BindTo((System.Collections.IEnumerable)ViewData["ApprovalCountry"])
)

Is there a way to cancel the changes of one field in one item in the DataSource?

Let us say that the user is modifying in the grid one item and he wants to cancel the changes of this item (one specific field) and not all his changes in the grid, can this be done?
