I have a mobile listview bound to kendoui datasource pointing to an odata service. I have a $expand hint in the datasource config to expand "Patient" property of "Claim" object, but looking the url of the odata query, the kendoui datasource is not generating the $expand code in the querystring. How can I get the kendoui datasource to generate correct $expand instruction on the querystring?

    OData query string genereated: http://localhost:1839/OData.svc/Claim?$callback=jQuery20207924230222124606_1374374358450&%24inlinecount=allpages&%24format=json&%24top=10

    <script>
        $(function () {
            var app = new kendo.mobile.Application(document.body, {
                transition: 'slide'
            });

            OData.defaultHttpClient.enableJsonpCallback = true;
            
            
            var data = new kendo.data.DataSource({
                type: "odata", // specifies data protocol
                pageSize: 10,  // limits result set
                transport: {
                    read: "http://localhost:1839/OData.svc/Claim",
                    dataType: "json",
                    data: {
                        $expand: "Patient"
                    }
                },
                schema: {
                    model: {id: "Id"},
                    data: function (data) {
                        return data.d.results;
                    },
                    total: function (data) {
                        return data.d.__count;

                    }
                },
                pageSize: 10,
                serverPaging: true,
                serverFiltering: true,
                serverSorting: true
            });

            $("#lst").kendoMobileListView(
            {
                template: "<strong>${data.ClaimNumber}</strong><br/>",
                filterable: {
                    field: "ClaimNumber",
                    operator: "contains"
                },
                dataSource: data
            });
        });

Lets say i have different types 'A','B','C' in my app 

and I am trying to assign this below result of type 'A'

class A
{
  List<B>

  List<C>
}

to the tree view at any level. Can the tree view read all the list items of B and C from the object of type 'A'.

Something like this below:

+ B (parent tree view items)
     - child tree view items
+ C (parent tree view items)
    - child tree view items

Please help with any suggestions.

I have a grid and I am editing most of the fields inline. However I have
a field, the way I envision to modify this field is to open a popup
window when clicked ( this will be a hyperlink field in the grid). Once
the value is modified in the Popup the change will be saved in the
database and the same change should also reflect in the grid. The grid
should be refreshed once the popup is closed. Can you please suggest me
as to how to accomplish this. Also can you provide me samples as to how
to do this.
Thank you

My app has a large list of data (only 1 column) and I have to show them all (no paging). With a small amount of data it works fine but when I have all the data in (around 260 items, not that many) the grid disappears from the page. Debugging shows a 500 error on the server. 

I have done the following testing:
- I tried the page on Chrome, IE and Opera. All give the same result.
- I replaced the grid with a treeview. Same result - with around 150 entries it's fine, with 260 it disappears (although in the case of the treeview it doesn't disappear completely, it leaves a message that the request failed and a button to retry.

How I'm getting the data:

@(Html.Kendo().Grid<Song>()
                      .Name("SongsGrid")
                      .Columns(columns =>
                          {
                              columns.Bound(o => o.Name);
                          })
                      .DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("SongList", "Song")))
                      .Selectable()
                      .Events(events => events.Change("songSelected"))
                      )

and

@(Html.Kendo().TreeView().Name("treeviewSongs")
            .HtmlAttributes(new {@class="demo-section" })
            .DataTextField("Name")
            .DataSource(dataSource => dataSource.Read(read => read.Action("SongListForTreeview", "Song")
        )

What are my options?

Thanks.

Hello all,

I have a grid that I list all the folder and the size of the folder, I have java script code that transform a size of the folder accordingly.  So a folder size can be 8 MB, 1 Gig, 400 KB, etc.  Obviously, this is a text field so we can give the user the correct information and the unit we measure the size of the folder.  Sorting does not work correctly since it is text. 

Is there a way to say for this column if you are going to sort this text column using the raw size field (or specify a specific column to use for sorting).  Meaning I have a second column in my model that has the raw size as int and I would like to use for sorting this way, 8 MB will come before 1 Gig folder.

Is there a way to do this?  if so can you provide a simple example please.

Hello,

I have attached two screens for understanding the issue.
And also attached Demo html folder which is downloaded from your site. I have edited html (examples\web\grid\index.html)
to minimize the number of columns shown in the grid.

Telerik/Kendo Users,

I have created a number of charts with filters based on an API and would like to know; is it possible to add a message to the graph if there is no data to display?
I do not believe that "DataBound" is useful as this would only cater for loading, not a lack of data.

Thanks,
Jamie

I'm looking to set column widths via HTML, either by setting the style attribute or using data-width (or something similar). I wasn't able to find anything in the documentation about defining column widths via HTML.

Thanks

Good Morning,

I appear to be running into a 6 color limitation for series.  The following jsFiddle highlights the issue: http://jsfiddle.net/sakers85/hn6nZ/

As you can see the Size "X" has duplicate colors for Grade CUL and WXB.  The same is true for Size "150" which has duplicate colors for Grade PRO and WXF.

Is my only option to explicitly set the seriesColors property with more colors than needed?  This could be an issue as the datasource is remote and can change at any given time based upon the request.

Please advise on the best course of action.  Thanks,
Sean

Good Morning,

I seem to be running into a color limit of 6 colors for series before the colors start repeating using default styles and settings.  Please take a look at this jsFiddle: http://jsfiddle.net/sakers85/hn6nZ/ which shows the undesired results.  As you can see for instance the "X" size has two series (CUL and WXB) with the same color.  The same is true for the "150" size with PRO and WXF.

Is my only option to use the seriesColors and explicitily tell the chart which colors to use?  This could be a potential issue as I may or may not know how many Grades come back from the server at any given refresh.  Please advise.

Thanks,
Sean
