Hi Guys,

Is it possible to create a chart like the one attached? Some values need to be grouped by an 'owner'. It can be for example a chart of tasks of some type assigned to different users.

Export to Excel in Hierarchial RadGrid

Hello Telerik Team,

I have developed a Hierarchial RadGrid using the approach given here:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/detailtabledatabind/defaultcs.aspx

Then added 'Export to Excel' functionality to the grid.
The code for the same is given here.

There are 2 issues with 'Export to Excel' functionality
1. 'Export to Excel' button when clicked first time works fine. But when I click it again, it does not work.
2. Data is exported only for the first level, not for the hierarchy tables.

<asp:Button runat="server" ID="Button1" OnClick="Button1_Click" Text="Export to Excel" />

protected void Button1_Click(object sender, EventArgs e)

{

ConfigureExport();

RadGrid1.MasterTableView.ExportToExcel();

}

public void ConfigureExport()

{

RadGrid1.ExportSettings.ExportOnlyData = true;

}

Please provide solution asap

CdnSettings

Hi,
I've localized RadEditor DialogBox and set CdnSettings-TelerikCdn="Disabled" of RadScriptManager and RadStyleSheetManager.
But when I watch the requests with FireBug it connects to telerik website.
And when internet is not connected the style of dialogs is disassembled.
Actually Telerik.Web.UI.DialogHandler.axd refers to telerikstatic.com.

Hiding Control In Master Page When in RadWindow

Hello,

I have a control in a master page that I want to display only when the master page is not in a RadWindow; when in a RadWindow, it should be hidden. Is that possible to do, to detect when the page request is inside the RadWindow?

Thanks.

Change color of ChartSeries pointmarks

I'm creating 8 series in my chart - 4 lines, 4 points, one point series for each line. Data is displaying fine. I have used the Hay skin but have opted to change the color of one of my lines. However, I can't seem to get the pointmarks in the point series to change color.

I'm creating my series as follows:-

protected RadChart SetChartData(RadChart radChart, DataTable chartDataTable)

{

radChart.DataSource = chartDataTable;

radChart.Series.Add(CreateChartSeries("Assets", ChartSeriesType.Line, "Assets"));

radChart.Series[0].Appearance.LabelAppearance.Visible = false;

radChart.Series.Add(CreateChartSeries("Assets calibrations", ChartSeriesType.Point, Color.Red, "AssetCalibrations"));

//radChart.Series[1].Appearance.PointMark.FillStyle.MainColor = System.Drawing.Color.Red;

radChart.Series[1].Appearance.LabelAppearance.Visible = false;

and so forth for the other 6 series

return radChart;

}

which calls my CreateChartSeries method:-

protected ChartSeries CreateChartSeries(string name, ChartSeriesType type, Color seriesColor, string dataYColumn)

{

ChartSeries chartSeries = new ChartSeries();

chartSeries.Name = name;

chartSeries.Type = type;

if (type == Telerik.Charting.ChartSeriesType.Line) { chartSeries.Appearance.LineSeriesAppearance.Color = seriesColor; }

if (type == Telerik.Charting.ChartSeriesType.Point) { chartSeries.Appearance.PointMark.FillStyle.MainColor = seriesColor; }

chartSeries.DataYColumn = dataYColumn;

return chartSeries;

}

I know my code is stepping into the 2nd if (type==Point) and it appears to set the color, but when my chart is rendered, the points are all colored by the Hay skin. I've even tried setting the color after the series.add (commented out now in my SetChartData method.

Hopefully I'm doing something daft?
thanks

Arrows on Hover

This is an odd one. I've put a couple of listboxes on my page and bound them to data. For some reason they both have a little 'double arrow' at the top left of each list item. The double arrow faces right and is present except when hovering over it.

I figure it must be intended for drag or 'move from listbox to listbox' type functionality, but I've set as many properties to 'false' as I can and they refuse to depart!!

Any help would be appreciated.
