Hi, we use a kendo grid with a popup editor.

@(Html.Kendo().Grid<OrderViewModel>()
            .Name("orderGrid")
            .Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("OrderDialog"))
            .ToolBar(x => x.Create().Text("Add Order"))
            .Columns(columns =>
            {
                columns.Bound(column => column.OrderID);
                columns.Bound(column => column.Name);
                columns.Command(column =>
                {
                    column.Edit();
                    column.Destroy();
                }).Width(230);
            })
            .Events(x => x.Edit("onGridEdit"))
            .DataSource(ds => ds.Ajax()
                .Read(r => r.Url("/Orders/Index?handler=ReadOrder"))
                .Update(u => u.Url("/Orders/Index?handler=UpdateOrder"))
                .Create(c => c.Url("/Orders/Index?handler=CreateOrder"))
                .Destroy(d => d.Url("/Orders/Index?handler=DestroyOrder"))
                .Model(m =>
                {
                    m.Id(id => id.OrderID);
                })
                .PageSize(10)
            )
            .Pageable()
        )

The OrderDialog looks something like this

@model Models.OrderViewModel

<div class="k-edit-label">
    @Html.LabelFor(m => m.Name)
</div>
<div class="k-edit-field">
    @Html.TextBoxFor(m => m.Name, new { @class = "form-control" })
</div>

...

We would like to be able to hide some fields in the editor if the entity being edited is new (which can be determined by the OrderID). This can be achieved by using the edit event of the grid, but we would rather like to do it based on a model property, like this:

@if(Model.OrderID == 0)

Is this possible? When debugging, it seems the editor is initialized with a null model, so that the line above crashes.

Hi, 

?EGood Day,

 

I am new to kendo ui and we are having an issue due to the upgrade of Jquery (1.x.x->3.6.0). The issue is "Syntax error, unrecognized expression: .field-validation-valid[data-valmsg-for=], .field-validation-error[data-valmsg-for=]" once the validation on the screen fires. Correct me if I am wrong, kendo ui should not be dependent on any Jquery versions. We are also checking if we need to change the validation process instead of using the said kendo validator. We are still hoping that there is still a way to fix this issue.
Below is the kendo version we are currently using.

Kendo Version: 2012.3.1114.340
Platform: ASP.NET MVC

Found the cause _findMessageContainer it is on the kendo.web.js, will just comment this to fix the issue

Today I upgraded one of our web apps to the latest version of UI for ASP.NET MVC and since then the DropDownList component doesn't appear to be rendering/styled correctly. I recreated the theme using the Progress Sass Theme Builder tool to eliminate the stylesheet itself as the issue. I've included screenshots below of what the DropDownList component looks like before and after the upgrade. Can anyone advise? Thanks in advance.

Before upgrade:-

After upgrade:-

Implementation:-

@(Html.Kendo().DropDownListFor(model => model.AssetSubTypeId)
                      .OptionLabel("Asset Type/Subtype...")
                      .BindTo(new SelectList(Lookups.AssetTypeSubType, "Key", "Value"))
                      .Events(events =>
                      {
                          events.Change("onChange_AssetSubTypeDropDownList");
                      }))

I'm having an issue getting the selected item from the passed event, mostly because the demo uses "e.dataitem"

like this:

function onSelect(e) {
        if ("kendoConsole" in window) {
            var dataItem = e.dataItem;
            kendoConsole.log("event :: select (" + dataItem.Text + " : " + dataItem.Value + ")");
        }
    }
My attempt to recreate this failed, dataItem has no such members:


@(Html.Kendo().MultiSelect()
                              .Name("JobIds")
                              .HtmlAttributes(new { style = "Width:700px; height:60px; overflow-y:scroll;", aria_label = "editor" })
                              .DataTextField("job_name")
                              .DataValueField("job_id")
                              .HeaderTemplate("<div class=\"dropdown-header\">" +
                                        "<span style=\"width=350px\">Job Name</span>" +
                                        "<span style=\"width=350px\">Parent Name</span>" +
                                        "</div>\n <table>")
                              .ItemTemplate("<span class = \"namespan\">#: data.job_name #</span> <span class=\"parentspan\">#: data.job_parent #</span >")
                              .DataSource(source =>
                                {
                                    source.Read(read =>
                                    {
                                        read.Action("JobSearch", "SupportEditor");
                                    })
                                    .ServerFiltering(true);
                                })
                              .Events(e =>
                              {
                                  e.Select("Job_onSelect")
                                  })


function Job_onSelect (e) {
        var dataItem = e.dataItem;
        console.log("event :: select (" + dataItem.Text + " : " + dataItem.Value + ")");
    }


The console reads:


event :: select (undefined : undefined)


The only way i have managed to pull data is with direct reference to the multiselect like below:

function Job_onSelect(e) {
console.log($("#JobIds").data("kendoMultiSelect").value().toString());
}
But this does not provide the values of selected item value as it is selected; instead it only gives the full value of the multiselect before the change occurs (e.g. if 3 items are selected it only returns items 1 and 2, and when the first item is selected it returns nothing).

 $("#saveButton").kendoButton({
              click: function() {

                  var channelsData = $("#bans-grid").data().kendoGrid.dataSource.view();
                  var channelsDataJson = JSON.stringify(channelsData);

Hi,

I've been trying to set a grid in popup edit mode, with an upload in a custom editor template, but can't get this to work, the  doesn't have a value. Here's my editor template and controller, the view only have a grid set with ajax CRUD operations and popup edit mode. If this possible (a sync upload in editor template), or I need to set async save for the upload?

Controller:

public JsonResult InsertWithImage([DataSourceRequest]DataSourceRequest request, HttpPostedFileBase Picture)
        {
            var item = repository.CreateNew();
            try
            {
                UpdateModel(item);
                if (Picture != null)
                {
                    Picture.InputStream.Read(item.Image, 0, (int) Picture.InputStream.Length);
                    item.Image_Ext = Picture.ContentType;
                }
                repository.Add(item);
                unitOfWork.SaveChanges();
            }
            catch (Exception err)
            {
                ...
            }
            return
                Json((new[] { item }.ToDataSourceResult(request, ModelState)));
        }


EditorTemplate:

<fieldset>
    ...
    <div class="row">
            @Html.LabelFor(model => model.Image)<br />
            @(Html.Kendo().Upload().Name("Picture").Multiple(false)
                .HtmlAttributes(new Dictionary<stringobject>{
                                                                  {
                                                                      "style""width: 100%"
                                                                  }}))
            @Html.ValidationMessageFor(model => model.Image)
        </div>
</fieldset>

When activating the editable.mode in a checkbox it makes the UI control non clickable.


Details: When the mouse hover the checkbox it activates the editable mode on the checkbox but right after that when I try to click it the UI does not response.


Kendo UI version: '2016.1.112'

I'm a beginner who started learning ASP.NET Core just now and wanted to know what the difference was. How much does it differ? Do I need to know ASP.NET MVC fully before learning ASP.NET Core MVC?
