Backbutton Error

If you have a back button in the header (like in the kendo mobile view demo), follow a link to an external site, then use the back button on the browser to go back to the kendo page, the back button no longer works. I had this happen with links to different sites on different views. Chrome throws the following error when you click the backbutton in the header after coming back from an external link:
Uncaught TypeError: Cannot call method split of undefined kendo.mobile.min.js:13

It looks like the app loses its internal history when you leave and come back. Is there a way to check the history, or have it default to go back to the home view?

I am using version 2013.1.514 of kendo mobile.

Is there a GroupHeaderTemplate?

Hi,

Is there a way to customize the display of the group header as presented in the aggregates grid demo?

For instance, we would like the header to appear as an aggregated row with grouped data and totals for numeric columns.
Ideally, the grid would start with all groups closed and look like a summary grid. Then when the user expanded a group, the detail would look like it is part of the same grid, with the same column headers and positions and sizes (as opposed to the way the hierarchy demo is laid out with separate grids for the details).

Thanks,
Take care,
Ken Rubin

Link between DataSource objects

I have a Grid, with a KendoDataSource that provides the data. That grid has some aggregate data. The entire data sits in a KendoObservableObject in my VM.

01.vm.SetLayers = function (values) {

02. //this.LayerTable.data(values);

03. //this.LayerTable.aggregate = [{ field: "FileCount", aggregate: "count" }];

04. //this.trigger("change", { field: "LayerTable" });

05. this.LayerTable = new kendo.data.DataSource({

06. data: values,

07. aggregate: [

08. { field: "FileCount", aggregate: "count" },

09. { field: "Size", aggregate: "sum" }

10. ]

11. });

12. this.trigger("change", { field: "LayerTable" });

13.};

I have another calculated field in the VM which shows the sum and count:

01.var totalFiles = function () {

02. return this.LayerTable.aggregates().FileCount.count;

03.};

04.var totalSize = function () {

05. return this.LayerTable.aggregates().Size.sum;

06.};

07.vm = kendo.observable({

08. InfoTable: infoTable,

09. LayerTable: layerTable,

10. StatsTable: statsTable,

11. TotalFiles: totalFiles,

12. TotalSize: totalSize

13.});

I would like have the TotalFiles and TotalSize as column values in another Grid (which is backed by a different VM DataSource. Is this sort of chaining possible?

01.var infoTable = [

02. { Item: "Status", Value: "Initializing" },

03. { Item: "XHR2", Value: false },

04. { Item: "B64", Value: false },

05. { Item: "PouchDB", value: "" },

06. { Item: "Center", Value: "xx" },

07. { Item: "Date", Value: "xx" },

08. { Item: "Zoom", Value: 0 },

09. { Item: "Total Files", Value: 0 },

10. { Item: "Total Size", Value: 0 }

11.

12.];

Set Column Height to Always Take Up 100% of it's Container

Hello,

I'm working on styling a stacked bar chart and I want the chart to always take up 100% of it's containers height no matter what the data values are. I will be binding local json data to this chart so obviously the values will change. I wasn't sure if there was a way to set the valueAxis max property to do this? Any help is appreciated!

Using custom TreeViewItem fields in template

Hi,

I currently am using the MVC wrapper extensions to create a TreeView from my models. I would like to pass some data from the model to the template so that I can display it alongside the text upon click.
Here is my TreeView:

@(Html.Kendo().TreeView()

.Name("s-list-event-container")

.HtmlAttributes(new { @class = "s-list-container", style = "color: white" })

.Events(events => events

.Select("preventSelect")

)

.TemplateId("template-list-event")

.BindTo(Model.ToList(), mapping => mapping

.For<ArdentMC.Sentry.Data.Event>(binding => binding

.Children(e => e.EventObjects)

.ItemDataBound((item, e) =>

{

item.Id = e.EventID.ToString();

item.Text = e.Name;

// Here's where I'd like to add a description. The line below runs but appears to do nothing.

item.HtmlAttributes.Add("data-description", e.Description);

})

)

.For<ArdentMC.Sentry.Data.EventObject>(binding => binding

.Children(o => o.EventObjects)

.ItemDataBound((item, o) =>

{

item.Id = o.EventObjectID.ToString();

item.Text = o.Name;

})

)

Thanks for any help,
Jeff

Children of DataItem

Hi,
I have a static HierarchicalDataSource defined in a file. I use it as source for a TreeView. TreeView has an 'expand' event fired before expand actually occurs. In that event I can get dataItem related to the node that is being expanded. I need to get children of that dataItem but I cannot see any method/property on dataItem that would allow me to get them. Is there any way to get/load child items?

I would be most grateful for any help :)

TypeScript definitions and interface DropDownListOptions template property

I download the new 0.9 Typescript definition file from the forum and it fixed the 0.9 compatibility issues. However, it also brought back and error I had manually fixed but forgot to put a post about with the older version. The interface DropDownListOptions defined the template property as

template?: string;

But this does not work with kendo.template function which returns a function. Changing it to the following worked.

template?: any;

However, I think the following is more correct and also works.

(data: any) => string

Just looking through the file there seems to be some other places where I think this is wrong too.
