Drill through on Bar Chart

I would like to implement a drill through type action on a bar charts series.

Here is what i have so far:

@(Html.Kendo().Chart<BetaSMTRApp.Business.PrivateReportCardCumulativeInvestments>()

.Name("ChartInvestmentCumulations_" + item.FUND_INT.ToString())

//.Title("Cumulative Investments")

.Legend(legend => legend

.Position(ChartLegendPosition.Top)

)

.DataSource(dataSource => dataSource

.Read(read => read.Action("GetCumulativeInvestments", "PrivateReportCard", new { fundInt = item.FUND_INT }))

)

.Series(series =>

{

series.Column(model => model.Commitments).Name("Commitments").Color("Red");

series.Column(model => model.Distributions).Name("Distributions").Color("Green");

series.Column(model => model.Draw_Down).Name("DrawDowns").Color("Yellow");

series.Column(model => model.Fees).Name("Fees").Color("Brown");

})

.CategoryAxis(axis => axis

.Categories(model => model.YearCategory)

)

.ValueAxis(axis => axis.Numeric()

.Labels(labels => labels

.Format("${0}")

)

.Tooltip(tooltip => tooltip

.Visible(true)

.Template("#= series.name #: #= value #")

)

.Events (events=>events.SeriesClick("onSeriesClick"))

)

Javascript/JQuery


function onSeriesClick(e) {
    $("#window").data("kendoWindow").open();
    $("#undo").hide();
};

Kendo Window


@(Html.Kendo().Window()
    .Name("window")
    .Title("About Alvar Aalto")
    .Content(@<text>
        <div class="armchair">
            <img src="@Url.Content("~/content/web/window/armchair-402.png")"
                 alt="Artek Alvar Aalto - Armchair 402" />

            ecide the use. Interpretations of the shape in new colors and materials add to the
            growing Alvar Aalto Collection that remains true to his original design.

            Aino Marsio.

Oh and yes i know that the window is displaying static text... i will eventually be putting in a Grid to display the detail records (and question #2 relates to it)

Here are my 2 issues/questions:

1. The window does pop up when i click on a series. However the page behind it goes white and only the contents of the window appear. Is there a way to allow the calling web page still appear (and not go blank).

2. In the javascript call to open the window is it possible to pass the contents of e to it (e contains parameter values that i want to use in the pop up window).

Thanks,

Corey

Hide Column Based On Remote Data

I have a kendo grid that gets data remotely (because I use the export to excel functionality). The column headers are bound to my model which is passed as empty before the data source request gets the populated one.

@model ReportingPortalWeb.Models.HireReportViewModel

@(Html.Kendo().Grid<StockReport>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.SohQty).Title("Quantity");
columns.Bound(p => p.StockName);
...
columns.Bound(p => p.SiteAddress3);
columns.Bound(p => p.PostCode);
})
.ToolBar(tools => tools.Excel())
.Groupable()
.Excel(excel => excel
.FileName("Kendo UI Grid Export.xlsx")
.Filterable(true)
.ProxyURL(Url.Action("CustomReport_Data", "Reports"))
)
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("CustomReport_Data", "Reports").Data("GetData")))
.Pageable()
.Sortable()
.Scrollable()
.Filterable()
.HtmlAttributes(new {style = "height:550px;"})
)

Before having to use the excel export I passed the data when the gird was created and I could hide a column easily by doing something like

columns.Bound(p => p.PrCode).Visible(Model.StockReport.Count(t => t.PrCode.Any()) > 0);

now that I am remotely fetching the data instead, is there a data on load event that I can use to hide the columns in my report that don't have any data in them?

Kendo grid, batch editing and notification box

Hello,

I have seen examples of confirmation boxes applied to inline / cell editing.

How can I display a confirmation ("saved successfully" or "not saved successfully" using something like notification widget if the grid batch editing mode is used?

The Save command is calling the controller action for Save and returns a JSON request as a response. But I don't know yet to get the additional notifaction displayed.

Yours

Stephan

Let's assume there is a xlsx file and I want to load this file to Spreadheet control.

Controller code:

var workbookJson = workbook.ToJson();

var model = new ExcelViewerViewModel()

Name = "Test",
Sheets = JsonConvert.DeserializeObject<IEnumerable<SpreadsheetSheet>>(workbookJson), <--- the problem to deserialize sheets
};

return PartialView("~/Views/Shared/_ExcelViewer.cshtml", model);

The View code:

@(Html.Kendo().Spreadsheet()
.Name("excelViewer")
.Toolbar(false)
.BindTo(Model.Sheets))

So the question is how to get IEnumerable<SpreadsheetSheet>> type from workbook?

Thank You

Trial 2015.3.930 only partially installed

Hello,

I noticed today that the status of my trial application is only 'partially installed'. I upgraded it to a newer version during my trail period.

When I choose to repair the installation, the status remain. (please refer to attached a screenshot from my Telerik Control Panel).

Question - can I safely remove the product, then re-install without losing work ?

Thanks,

Grid Inline Editing Resources issue

Hello everyone,

I’m struggling with something really annoying.
In my ASP.NET MVC project I have plenty of Kendo Grids in inline editing mode with French resources activated.
Everything works just fine, except when I deploy my project online. The “add new record”, “edit” and “delete” were supposed to be in French but they are in English.
However, if I start adding or even editing one line, the “update” and “cancel” buttons are well translated in French.
I assume that this is something else for two reasons: everything just works fine running in local and almost all French resources are well visible in grid.
So, can anyone advise me or help me with this, please?

Thank you so much in advance,
Best regards,

Grid

OfflineStorage and Virtual scrolling

Anyone know if offlineStorage would let users scroll through previous pages that were loaded via virtual scrolling? Can they come back to a page that was closed and see their cached data? Is there a feature that would allow this?
