RadLinearSparkline inside of Cell for Pdf Document

[Andrey]

Hi all.

I'd like to render the RadLinearSparkline control inside of the Table Cell, and then export document to PDF.
here is the code:

private static void AddTrendCell(IBlockContainer cell, IEnumerable<double> value)
{
    var trendLine = new RadLinearSparkline();
    trendLine.ItemsSource = value;
    trendLine.LineStroke = new SolidColorBrush(Colors.Red);
    trendLine.Background = new SolidColorBrush(Colors.Green);

    var paragraph = new Paragraph();
    paragraph.Inlines.Add(new InlineUIContainer(trendLine, new Size(180, 30)));
    cell.Blocks.Add(paragraph);
}

but there is no any content inside of Cell in the PDF document.
please help.

Hello Andrey,

Your code seems to be fine. However, you should explicitly set width and height of the control contained by the container:

trendLine.Width = 180;
trendLine.Height = 30;

If your problem persists, have in mind that if the item is not displayed properly in a RichTextBox when the document is previewed in one, it will also not be exported to PDF since the export consists of making a "screenshot" of the visible content.

Don't hesitate to contact us if you have other questions.

Kind regards,
