I am trying to export a page to PDF that contains RadHtmlCharts, but I am getting a RadAjaxManager error.

Here is the html:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>

<telerik:RadHtmlChart ChartTitle-Text="Overall" runat="server" ID="rcOverall" Width="600px" Height="400px" Skin="Bootstrap" DataSourceID="sqlOverall" RegisterWithScriptManager="false">
            <PlotArea>
                <Series>
                    <telerik:BarSeries Name="BarSeries1" DataFieldY="points">
                        <LabelsAppearance Visible="false" />
                        <TooltipsAppearance Visible="false" />
                    </telerik:BarSeries>
                </Series>
                <XAxis DataLabelsField="Section" >
                    <TitleAppearance Text="Section">
                        <TextStyle FontSize="12" Bold="true" />
                    </TitleAppearance>
                </XAxis>
                <YAxis Visible="false" MinValue="0" MaxValue="27" Step="3">
                    <TitleAppearance Text="Total Mark">
                        <TextStyle FontSize="12" Bold="true" />
                    </TitleAppearance>
                </YAxis>
            </PlotArea>
            <Legend>
                <Appearance Visible="false" />
            </Legend>
        </telerik:RadHtmlChart>

The code to export is:

 Response.ContentType = "application/pdf"
   
        Response.AddHeader("content-disposition", "attachment;filename=Image.pdf")
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
         Dim sw As New StringWriter()

        Dim hw As New HtmlTextWriter(sw)
        Me.Page.RenderControl(hw)

        Dim srdr As New StringReader(sw.ToString())

        Dim pdfDoc As New Document(PageSize.A4, 15.0F, 15.0F, 75.0F, 0.2F)

        Dim hparse As New HTMLWorker(pdfDoc)
       
        PdfWriter.GetInstance(pdfDoc, Response.OutputStream)
        pdfDoc.Open()

        hparse.Parse(srdr)

        pdfDoc.Close()

        Response.Write(pdfDoc)
        Response.[End]()

When I run it I get an error:

Script control 'RadAjaxManager1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().

Can anyone please help with this as I have looked everywhere and anything I have tried doesn't work!!!.

Any help would be very welcome. 

Thanks

I am trying to export a page to PDF and when the code reaches the page render section, I am getting an error for the RadAjaxManager. 

I have several RadHtmlCharts on the page and am trying to export them to a PDF. Here is a snippet of the control:

 <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    </telerik:RadAjaxManager>

                <Series>
                    <telerik:BarSeries Name="BarSeries1" DataFieldY="points">
                        <LabelsAppearance Visible="false" />
                        <TooltipsAppearance Visible="false" />

Hi,

I have a situation where we're wanting to use a Gantt in an ASP.NET repeater (so the user can look at individual project meta data and progress etc). However the Rad Gantt doesn't appear to play nicely in a repeater.

As soon as I add the gantt control (whether straight into the repeaters item template, or in a user control) it tries to do it;s binding and rendering while the repeater's header is being processed. 

Any suggestions?

Cheers

I've tried everything I can think of to get the export working but I keep getting:

System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: Width must be non negative.

I do not know which control(s) this is referring to.....

Hi,

I cannot get any kind of information out of spreadsheet. sheet count is zero, I could not figured out how to access cells...

I load demo xlsx files but I cannot access any information. also there's not much in help section.

I am trying to get the value of a Radeditor field in a User Control when updating to store it in my database table

In the update command of my grid I have tried using both of these commands

Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim MyUserControl As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)

Dim editorcomment As RadEditor
editorcomment = CType(MyUserControl.FindControl("Comment"), RadEditor)
editorcomment = editedItem.FindControl("Comment")

Neither of these commands brings back any data in editorcomment.Content

Please can you give me some code which will retrieve the Content of the RadEditor field
