[Solved] Pie Chart creation at Run-Time not working

Hello Telerik,

Please see this code here:.

01.Dim HBH_Chart As New RadHtmlChart

02. HBH_Chart.ID = "HBH_Chart"

03. HBH_Chart.Width = Unit.Pixel(500)

04. HBH_Chart.Height = Unit.Pixel(500)

05. HBH_Chart.Legend.Appearance.Position = HtmlChart.ChartLegendPosition.Right

06.

07. Dim HBHSeries As New PieSeries

08. HBHSeries.Name = "HBH1"

09. HBHSeries.TooltipsAppearance.DataFormatString = "{0}"

10. HBHSeries.LabelsAppearance.Visible = True

11.

12. For Each row As DataRow In dataSet.Rows

13. Dim item As New SeriesItem

14. item.YValue = row.Field(Of Integer)("AantalClienten")

15. item.Name = row.Field(Of String)("Naam")

16. item.BackgroundColor = System.Drawing.ColorTranslator.FromHtml(row.Field(Of String)("Kleur"))

17. Next

18.

19. HBH_Chart.PlotArea.Series.Clear()

20. HBH_Chart.PlotArea.Series.Add(HBHSeries)

21. HBH_Chart.PlotArea.XAxis.DataLabelsField = "Naam"

22. HBH_Chart.PlotArea.YAxis.LabelsAppearance.DataFormatString = "{0}"

23.

24. HtmlChartHolder.Controls.Clear()

25. HtmlChartHolder.Controls.Add(HBH_Chart)

I try to create a PieChart dynamically. But the only thing that I see is that it takes up it's space in the page (i.e. the placeholder is filled). But the actual chart is not visible. It's see as a white rectangle. What am I missing here?

Thanks a lot for your answer,

Best regards,
Francois

Show popup while click on a link in Grid

Hi,

I am new to telerik. Now i am using telerik trial version.
I have once scenario.
> Grid contains 10 rows
> One column is template column, which contain a link button
> While click on the link, i need to open a popup, like model window. The model window should show some details about the clicked records.
> Data displayed in the model window based on the arguments received from the link button

Kindly suggest how can i implement this. Which control can i use for getting this feature.

All my bindings are dynamic and i cannot set any datasource in the design.

I need the feature almost similar to hierarchical data grid. Where can get the more details about the real implementation. In the "step-by-step" tutorial it is not much explenatory and datasource is set in the markup itself.

Error when expanding a NestedViewTable in RadGrid when a row is selected

Error when expanding a NestedViewTable in RadGrid when a row is selected and HierarchyLoadMethod is ServerOnDemand.

I have a RadGrid with a NestedViewTable. HierarchyLoadMethod is set to "ServerOnDemand". I can expand the NestedViewTable just fine unless I first select a row. The error message is within a Telerik JS file and reads: "Input string was not in acorrect format." This works when I set the HierachyLoadMethod to "ServerBind" however this takes way too long. It appears to be a Telerik issue to me. Please provide guidance on how I can solve this problems. Thank you.

Pasting from Excel

Hi, I've been searching the forum and Google in general to try and find an answer to this question:
How do I enable pasting from excel into a KendoUi Grid?
I've seen solutions for 'RadGrid', but not the newer 'grid'...
Would welcome any help, even in just capturing the pasting event.
Regards,
Tony.
