[Solved] TabStrip BindTo content using Action

So I originally defined a TabStrip and manually loaded the content using LoadContentFrom with an Action which returned a PartialView of content defined in another .cshtml. It worked fine.

Now I want to do something similar, but have the items of the TabStrip bound to a collection. The TabStrip is binding the text of the item just fine, but the Action to get the content is never being called. How do I define it so that it does, similar to LoadContentFrom?

If my old implementation is:

@(Html.Kendo().TabStrip()

.Name("tabStrip")

.Items(items => {

items.Add().Text("Test").LoadContentFrom("MyAction","MyController", new { id = 0 });

})

)

How do I translate that to:

@(Html.Kendo().TabStrip()

.Name("tabStrip")

.BindTo(Model, (item, category) =>

{

item.Text = category.TestText; // works

item.Action("MyActions", "MyController", new { id = 0 }); // Doesn't seem to do anything

})

)

[Solved] Stacked Bar using AJAX - how to project the model?

I have restricted horizontal space on a page, but have multiple values to display in a graph. I thought a single-column, stacked column chart would fit the bill. I'm interested in showing proportion of values.

I have a simple model:

UserName
Items

Using the AJAX mechanism shown here http://demos.telerik.com/aspnet-mvc/bar-charts/remote-data-binding I can get the chart to display using the following code:

@(Html.Kendo().Chart<RequestLoadingSummaryAggregate>()

.Name("resourceLoadingChart")

.Title("Resources")

.Legend(legend=>legend.Visible(false))

.DataSource(dataSource=>dataSource.Read(read=>read.Action("RequestLoadingSummary","Home")))

.Series(series =>

{

series.Column(model => model.Items).Name("Resource");

})

.CategoryAxis(axis=>axis

.Categories(model=>model.UserName)

.Labels(labels=>labels.Rotation(-90))

.MajorGridLines(lines=>lines.Visible(false))

)

.ValueAxis(axis=>axis.Numeric()

.Labels(labels=>labels.Format("{0:N0}"))

.MajorUnit(100)

.Line(line=>line.Visible(false))

)

.Tooltip(tooltip=>tooltip

.Visible(true)

.Format("{0:N0}")

)

.ChartArea(chartArea=>

chartArea.Height(400))

)

But I cannot get it to work as a Stacked Column using the additional defaults:

.SeriesDefaults(seriesDefaults =>

seriesDefaults.Column().Stack(ChartStackType.Normal)

)

How can I project the model from the AJAX result into a form that the chart can understand such that the values occupy a single column with multiple values?

Thanks

Nathan

Upgrade Wizard for Kendo UI v2014.3.1316 fails

I just tried upgrading my VS2013 solution to v2014.3.1316 of the MVC UI. It's failed three times now. My solution has two MVC enabled projects using the 2014.3.1223 internal update (which I had to manually install for probably the same reason) in it and I tried to update both at the same time. I got the following error:

An error occurred while running the wizard.Error executing custom action Telerik.KendoUI.Mvc.VSX.Actions.MultiProjectCopyResourcesAction: System.Runtime.InteropServices.COMException (0x8007007C): Error deleting file 'kendo.messages.ru-RU.min.js'.

What gives?

Update Grid PageSize not working in ClientSide Paging Grid

I am working on a Client-Side paging grid (ServerOperation(false)) where I need to manually update the page size when a new row has been added using the grid's dataSource.insert() method. The reason for this is because I want to have the new record visible as well as any other existing records on the grid on the same page.

I am updating the page size using the following code when a new record is added:

var grid = $("#myGrid").data("kendoGrid"

);

var

currentPageSize = grid.dataSource.pageSize();

grid.dataSource.pageSize(++currentPageSize);

grid.refresh();

Unfortunately, the above code does not work for Client-Side paging but it works on Server-side paging.

Any assistance would be very welcome.

[Solved] Invoke the PDF export from the Toolbar component

Hi,

I can see that the Grid component can produce PDF (and Excel) exports, which is ideal.

But, how can I invoke the functionality from outside of the native Grid toolbar?

In the example below, I want to invoke the PDF export of the Grid using the Toolbar component (though it could be any external stimulus)

01.@(Html.Kendo().ToolBar()

02. .Name("ToolBar")

03. .Items(items =>

04. {

05. items.Add().Type(CommandType.SplitButton).Text("Export").ImageUrl(Url.Content("~/Content/web/toolbar/save.png")).MenuButtons(menuButtons =>

06. {

07. menuButtons.Add().Text("Export to Excel").ImageUrl(Url.Content("~/Content/web/toolbar/save.png"));

08. menuButtons.Add().Text("Export to PDF").ImageUrl(Url.Content("~/Content/web/toolbar/upload.png"));

09. });

10. })

11. )

12. @(Html.Kendo().Grid<RequestWorkflowWithWatcherViewModel>()

13. .Name("grid")

14. .Columns(columns =>

15. {

16.// columns stuff

17. })

18. .ToolBar(tools =>

19. tools.Pdf())

20. .Pdf(pdf => pdf

21. .AllPages()

22. .FileName("Kendo UI Grid Export.pdf")

23. .ProxyURL(Url.Action("EnquiryExportToPdf", "Home"))

24. )

25.

26. ))

Ultimately I want to do the same with Excel.

Any ideas would be welcome.

Many thanks

Nathan

Grid Randomly Not Getting Correct Data-Roles Set

Has anyone ever experienced a grid not getting any of the data-roles applied to the markup when the page loads? This seems to happen randomly, but usually when we open up the Kendo Window that contains the grid very quickly after the page loads.

It almost looks like we are going too quick for Kendo to catch up and create the proper markup.

Has anyone else seen a problem like this?
