I want to use the Grid Inline editing that presents an Update and Cancel button but I want to intercept the Update request so that I can call the Update event in the controller when a custom "Save" button is clicked.

Right now I can tap into the Update event and call grid.cancelRow() and call e.preventDefault() but in doing so when the grid cancels the edit returns the data to it's original state.  I know this is desirable for the normal scenario but in this scenario I want the update button to close the edit template in the row and leave the updated values in place and to leave the record marked as dirty.

Optimally it would leave the red triangle modified indicators in the modified cells.

Any suggestions would be appreciated.

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>

Thoughts

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);

                        for (var i = 1; i < 23; i++)
                        {
                            cells.Add()
                            .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();
                            cells.Add();
                            cells.Add();
                            cells.Add().Formula("J" + i + "*W" + i); // calculated freight cost
                            cells.Add();
                            cells.Add();
                            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?
