Is it possible to sum a column without including all rows in that column.

IE
a  2
b  3
c  2
d  8
sum = 12

but only sum up a+c+d

I'm not sure what is the best way for my scenario, so I'll explain that first.

I have two datasources. Persons and Groups, each Person-Item has an indicator, to which group it belongs to. The persons are binded to a kendo-grid and the groups to a <ul>. My problem is, that I want to display a count-number besides the group, which indicates how many persons are in that group - this information is calculated from the persons-datasource and not part of the group itself.

Sorry for that generic question - but I'm really struggling with this...

I have a kendoObservable (numeric value) that is bound both to a span (text: ) and a kendo slider (value:)

I have a button that increments the value. But only the text version is updating. What did I do wrong?

An example is worth a thousand words:

One wrinkle here is that i need to dynamically add the slider. So there is a button at the top that you have to hit first, to add the slider to the DOM. Then just press the [increment] button to see what is going on.

(do I have to rebind the VM, after adding the slider?).

I have an object:
And in the editor template, where model.Members are a collection of Users
When posting the form containing this multiselect I get the following post data
Now as far as I can tell the post data is correct, except for"Members:[object Object]" which Kendo throws an error for. When the model is received by the controller, the Members field is null.

What settings are incorrect?

(Note that MemberRead is populating the MultiSelect correctly)

(Also note that this form is part of a popup editor of a grid, in which everything else is working correctly)

Hello,

I could use a bit of advice.

I am working with a listview that has tiered sections. I can click on each branch in the tree to drill down to the next level. It looks like this: 
This is working - the problem occurs if I revisit a view. If I click through the list, updating the dataSource and showing the new options, I can't go back and choose a different option. If I try, I am met with an "Uncaught TypeError: Cannot read property 'sectionId' of undefined". 

It's a category list with sub-categories underneath. If I click Shoes > Sandals > Flip-Flops everything works, but if I try to go back and change from Flip-Flops to something else, I'm met with the TypeError.

This tells me that the data isn't getting bound to the view when I go back (right?). I currently use onShow() to set up the dataSource. When using onBeforeShow() the list won't update with new data after the first time through, so going back and selecting Hiking Boots instead of Sandals will still show me the results for Sandals.

Is there another method I could use to get this data to show up correctly on subsequent passes through the list?

Thanks!

Currently I am receiving an error when accessing a Kendo Window of a partial page with a Grid inside:

SCRIPT5022: DOM Exception: NOT_FOUND_ERR (8) 
kendo.web.min.js, line 16 character 31193

l.table[0].replaceChild(r,l.tbody[0])

My window Kendo window code is as follows:

@(Html.Kendo().Window()
                    .Name("mbWindow")
                    .Width(630)
                    .Height(530)
                    .Title("Add Element")
                    .Content(
                    @<text>
                    @Html.Partial("../Controller/PartialPage")
                    </text>)
                    .Draggable()
                    .Visible(false))

My partial page is as follows:

@{
    ViewBag.Title = "Elements";
}
<h2>
    Elements</h2>
<div id="mxBWindow">
    @(Html.Kendo().Grid<Model.MB>()
            .Name("MBGrid")
                .HtmlAttributes(new { style = "height:460px;" })
            .Columns(columns =>
            {
                columns.Bound(p => p.ID);
                columns.Bound(p => p.Amount);
                columns.Bound(p => p.ParentID);
                columns.Command(command => command.Destroy()).Width(110);
            })
            .ToolBar(toolbar =>
            {
                toolbar.Create();
                toolbar.Save();
            })
            .Editable(editable => editable.Mode(GridEditMode.InCell))
            //.Pageable()
            //.Sortable()
            //.Selectable(s => s.Enabled(true))
            //.Navigatable(n => n.Enabled(true))
            .DataSource(dataSource => dataSource
                .Ajax()
                .Batch(true)
                .ServerOperation(false)
                .Events(events => events.Error("error_handler"))
                .Model(model => model.Id(p => p.ID))
                        .Create("Editing_Create", "Grid")
                        .Read("Editing_Read", "Grid")
                        .Update("Editing_Update", "Grid")
                        .Destroy("Editing_Destroy", "Grid")
            )
                .Events(ev => ev.SaveChanges("submitElements"))
    )
</div>

I have noticed that when I remove this Grid from the partial page, the window gives me no errors. Both pages, however, when accessed individually give me no errors. Yet when I add the Grid back in with the Kendo Window, I get the DOM Exception.

Page w/Grid - No Errors
Page w/Window - No Errors
Page w/Window(w/Grid Inside) - Error/DOM Exception

Could someone please point me out what might be causing this error?

Dear Kendo Team,
When i resize a column in a detail row, the detail grid has a strange expansion behavior (see file in attachment)
Could you provide a work around or something else in order to solve the issue?
Thanks in advance
Best regards

I wanted to use observable object for my grid, hoping that the performance would be better then what i was getting before.
but i am not sure if it is. I also am confused about the usage.
It seams to be pretty much the same thing.

[I use TypeScript, that's why the code looks a little bit different to pure JS]

When i add a new item.
With the old way i did something like this:
then i changed it to observable object way like this:

Can't see any performance differences.

The weird thing is when i try to edit the items.
In the old way i did this:
i expected not to have to run the grid refresh with the observable object. But it turns out i still had to do it. or it would not show any changes.
The new code loos like this:
so it's basically the same thing.
I don't get what the advantage is here, especially with the editing of the rows.

Am i using it wrong?

How can I override the following, so my application scales correctly on Iphone 5?

Can I simply add the following statement to override, or do I have to pass this as some sort of parameter somewhere?

Can someone please provide me with a few lines of code to get the value of a checkbox in a column in a Kendo Grid. Starting with this code:

columns.Bound(o => o.Resolved).ClientTemplate("&nbsp;&nbsp;&nbsp;&nbsp;<input type='checkbox' # if (Resolved) { #checked='checked'# } #/>").Title("Resolved").Width(60).Sortable(false);
                  
var data = $("#Appointments").data("kendoGrid").dataSource.data();

$.each(data, function (index, item)
{ trArray = { "Resolved": item.Resolved    <<--- This gives me the value IN THE MODEL --- I WANT WHAT THE USER HAS SELECTED!       }; });

Please don't send me a solution that hangs Visual Studio for an answer.

Thanks,
