I am trying to use a ListView control in an ASP.NET RC1 project. I have added all the required stuff from the documentation..

1. js and styles folders

2. script references in layout 

<script src="~/lib/kendo-ui/js/jquery.min.js"></script>
<script src="~/lib/kendo-ui/js/kendo.all.min.js"></script>
<script src="~/lib/kendo-ui/js/kendo.aspnetmvc.min.js"></script>

3. services.AddKendo(); in Startup.cs

However when I add this to my page I am getting a javascript error

jquery(...).kendoListView is not a function

@(Html.Kendo().ListView<Microsoft.Graph.Group>()
.Name("groupView")
.TagName("div")
.ClientTemplateId("grouplistTemplate")
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("Groups_Read", "Groups"))
)
)

What could the issue be?

Thanks

I've overridden the treeview CSS using the following code and while everything looks fine in desktop Chrome/IE/Firefox I'm having trouble in Chrome on Android.  I'm seeing multiple icons to expand and contract the treeview nodes.  It appears to be displaying a 64px square of the sprite.

<style scoped>
    .k-icon, .k-tool-icon, .k-grouping-dropclue, .k-drop-hint, .k-column-menu .k-sprite {
        background-image: url('/content/kendo/2015.1.429/default/sprite_2x.png');
        border-color: transparent;
    }

    .k-icon {
        width: 32px;
        height: 32px;
    }

    .k-treeview .k-item {
        font-size: 28px;
    }

    .k-treeview .k-minus {
        background-position: 0 -256px;
    }

    .k-treeview .k-plus {
        background-position: 0 -286px;
    }

    .k-treeview .k-in {
        line-height: 32px;
    }

    .k-treeview .k-item, .k-drag-clue {
        font-size: 28px;
        padding: 0 0 0 32px;
    }

    .k-add {
        background-position: -96px -416px;
    }

    .k-insert-middle {
        background-position: -320px -96px;
    }

    .k-denied {
        background-position: -96px -96px;
    }

    .k-insert-bottom {
        background-position: -320px -128px;
    }

    .k-insert-top {
        background-position: -320px -64px;
    }
</style>

I have a Kendo MVC Grid that has inline editing enabled.  The form has a master SAVE button on top of the form.  The intent is to let the user modify multiple rows and then do one master save.

So right now the EDIT button allows the user to edit the row values and presents an UPDATE button.  This works in that the update method specified in the grid's configuration fires the controller event.  In that event I just return the row that was sent in.  That is all working but we would like the red indicator to show in the row in the modified cells after the controller action and then be cleared when the master save button is clicked, and the JavaScript submits the form's modified rows to that controller action in an AJAX batch action on the form.

Can someone offer a possible solution?

Thanks

I stuggle with this grid and editortemplate with a combobox. My model has a int? idAfdeling that is the foreign key.

With the valuePrimitive set to false, the idAfdeling remains null after a combobox item is selected, it will update once the initial idAfdeling is not null.

With the valuePrimitive set to true, the idAfdeling is updated after selecting an item, but the autobind option is not respected and an ajax call is made.

Now i wonder if there is any option to make the combination (combobox, nullable int, bind on demand) work..

How would one go about accomplishing the following in MVC: Import data from a database into the spreadsheet control and implement formula cells in certain columns.

I'm not sure the methodology to work in a sort of hybrid method using this control. Is there a way to feed formulas from the controller? Currently I am adding null values to properties of my viewmodel so the columns can show up in the spreadsheet, but these wipe out the formulae I am placing in the column. Here is the code I am using. Not the most elegant :)

@(Html.Kendo().Spreadsheet()
        .Name("spreadsheet")
        .HtmlAttributes(new { style = "width:100%" })
        .Excel(excel => excel
            .ProxyURL(Url.Action("Index_Save", "Spreadsheet"))
        )
        .Pdf(pdf => pdf
            .ProxyURL(Url.Action("Index_Save", "Spreadsheet"))
        )
        .Sheets(sheets =>
        {
            sheets.Add()
                .Name("Products")
                .DataSource<BBC.Bids.ViewModels.OrderViewModel>(ds => ds
                    .Ajax()
                    .Batch(true)
                    .Read(r => r.Action("Orders_Read", "Grid").Data("selectedOrder"))
                    .Update("Products_Update", "Spreadsheet")
                    .Create("Products_Create", "Spreadsheet")
                    .Destroy("Products_Destroy", "Spreadsheet")
                    .Events(e => e.Change("onChange"))
                    .Model(m =>
                    {
                        m.Id(p => p.LineNo);
                    })
                )
                .Columns(columns =>
                {
                    columns.Add().Width(25);
                    columns.Add().Width(200);

                        {

                            .Bold(true)
                            .Background("#9c27b0")
                            .TextAlign(SpreadsheetTextAlign.Center)
                            .Color("white");
                        }
                    });

                    for (var i = 2; i < 500; i++)
                    {
                        rows.Add().Cells(cells =>

                            cells.Add();
                            cells.Add();
                            cells.Add();
                            cells.Add().Formula("J" + i + "*W" + i); // calculated freight cost
                            cells.Add();

Hi,

I have written a function that triggers when the Update event on the grid ends.  This is defined as :

My function is as follows:

The problen that once the updateend function trigger, the console returns an error saying that dataItem is null (start_date) which crashes the application.  What am I doing wrong and why can't I grab that cell data for use in my function?

Many thanks

Hi,

I don't find an example to plot a heatmap /  intensity chart.

Is a chart similar to the chart in the attached file possible with ASP.NET MVC?

Is there a way to have a Custom Command Button that is only visible when the user is editing a cell and becomes invisible when the editing is complete?  And if so, when clicked resets the row to it's original values.  Right now if the model annotations specifies [required] for a field, if the user starts to edit that column then changes there mind they still have to enter a valid value there. 

I ask this because using the default Edit Inline mode the Update button when clicked hits the controller and resets the dirty flag on the records so the red indicators go away.  We want to have a custom master "Save" button that does a master save of all rows at once.

So basically a way to use the default Edit, Update, Cancel mechanism built into Kendo that just leaves the red indicators and dirty flags when the user clicks the update button and also snaps the row out of edit mode.  In this respect we would not need a custom "cancel" button.

Any suggestions would be welcome.

Thanks
