Javascript Error When Exporting to iCalendar

I'm following the instructions on:
http://www.telerik.com/help/aspnet-ajax/schedule_howtoexportingtoicalendar.html

to add the export feature to our online calendar already in production. Per the instructions I've added the code block to the .ascx:

    
                            <div style="text-align: right;"> 
        
                                 <span style="cursor: pointer; cursor: hand;"> 
        
                                 <asp:ImageButton runat="server" ID="Button1" ImageUrl="Outlook.gif" AlternateText="Export to iCalendar" 
        
                                 CommandName="Export" OnClientClick="Export(this, event); return false;" /> 
        
                                 </span> 
        
                            </div>

And the methods to my codebehind:

    
            private void WriteCalendar(string data) 
        
                    { 
        
                        HttpResponse response = Page.Response; 
        
                        response.Clear(); 
        
                        response.Buffer = true; 
        
                        response.ContentType = "text/calendar"; 
        
                        response.ContentEncoding = Encoding.UTF8; 
        
                        response.Charset = "utf-8"; 
        
                        response.AddHeader("Content-Disposition", "attachment;filename=\"RadSchedulerExport.ics\""); 
        
                        response.Write(data); 
        
                        response.End(); 
        
                    } 
        
                    protected void RadScheduler1_AppointmentCommand(object sender, AppointmentCommandEventArgs e) 
        
                    { 
        
                        if (e.CommandName == "Export") 
        
                        { 
        
                            WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment)); 
        
                        } 
        
                    }

the button shows up, however when I click it I get:

"Microsoft JScript runtime error: Object expected" And it highlights the "Export(this, event); return false;" in here:

    
            <input type="image" name="MasterCalendar1$RadScheduler1$ctl138$Button1" id="MasterCalendar1_RadScheduler1_ctl138_Button1" src="Outlook.gif" alt="Export to iCalendar" onclick="Export(this, event); return false;" style="border-width:0px;" />

I'm presuming this is because the Export() method hasn't been written in the .ascx as in the demo on the telerik site, however the instructions I was following do not mention this as necessary.

If this is the necessary code block:

    
            <telerik:RadCodeBlock runat="server"> 
        
                    <script type="text/javascript"> 
        
                        function Export(sender, e) 
        
                        { 
        
                            $find("<%= RadAjaxManager1.ClientID %>").__doPostBack(sender.name, ""); 
        
                        } 
        
                    </script> 
        
                </telerik:RadCodeBlock>

How do I change it to use it without the AjaxManager, I had to remove the AjaxManager to allow the calendar to work inside of sitefinity.

Checking Dotnetnuke has correct files

Hi.

Is there a general process to check if a dotnetnuke installation has the correct set of files if you have overwritten the default telerik dll with the normal telerik dll?

We updated the dll version in the web and release configs but there are numerous small errors appearing. I was under the impression that all necessary files/scripts etc where contained within the dll.

Thanks in advance.

Grouping on X axis

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.

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
--Michael
