How to use WindowStatus in HTML converter for WinForms PDF?

5 mins read

We can manually wait for HtmlConverter to complete the document loading using the WindowStatus property in the HTML converter. We can use WindowStatus instead of an additional delay. In an additional delay, we do not know the exact time needed for the execution of JavaScript. By using WindowStatus, you can avoid this problem.

Note:

Both WindowStatus values should be the same; otherwise, the converter will never stop the conversion.

Assemblies Required:

1) Syncfusion.Compression.Base.dll

2) Syncfusion.HtmlConverter.Base.dll

3) Syncfusion.Pdf.Base.dll

Steps to use WindowStatus in the HTML converter programmatically in C#:

1)Create a new WPF application project.

2)Install the Syncfusion.HtmlToPdfConverter.WPF NuGet package as reference to your .NET Framework applications from NuGet.org.

3)Include the following namespaces in the MainWindow.xaml.cs file

 using Syncfusion.HtmlConverter;
 using Syncfusion.Pdf; 
 using System.Windows;

Add a new button in MainWindow.xaml to create a PDF document as follows.

<TextBlock TextAlignment="Justify" FontFamily="Verdana" FontSize="11" TextWrapping="Wrap" Padding="5,5,5,5" Margin="0,77,0,1">
<TextBlock.Background>
<LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
<GradientStop Color="#FFD9E9F7" Offset="0"/>
<GradientStop Color="#FFEFF8FF" Offset="1"/>
</LinearGradientBrush>
</TextBlock.Background>
<TextBlock.Text>
Click the button to view the PDF file generated by Essential PDF.
</TextBlock.Text>
</TextBlock>
<Button Click="btnCreate_Click" Margin="0,0,10,12" VerticalAlignment="Bottom" Height="30" BorderBrush="LightBlue" HorizontalAlignment="Right" Width="180">
<Button.Background>
<LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
<GradientStop Color="#FFD9E9F7" Offset="0"/>
<GradientStop Color="#FFEFF8FF" Offset="1"/>
</LinearGradientBrush>
</Button.Background>
<StackPanel Orientation="Horizontal" Height="23" Margin="0,0,0,-2.52" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="100">
<Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center"/>
<TextBlock Text="Create PDF" Height="15.96" Width="126" Margin="0,4,0,3"/>
</StackPanel>
</Button>

Add the following code in btnCreate_Click to create a PDF file with simple text:

// Create an HTML to PDF converter object with default settings
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
BlinkConverterSettings blinkConverterSettings = new BlinkConverterSettings();

// Set WindowStatus
blinkConverterSettings.WindowStatus = "completed";
htmlConverter.ConverterSettings = blinkConverterSettings;

// Convert URL to PDF
PdfDocument document = htmlConverter.Convert("input.html");

// Save the document
document.Save("Sample.pdf");

Input.html:

<html>
<head>

</head>
<body>
    <div id="message">
        Wait for 2 Seconds
    </div>

    <script type="text/javascript">
			   
        setTimeout(function () {
            document.getElementById("message").innerHTML = "Hello World!!";
            window.status = "completed";
        }, 2000);
    </script>

</body>
</html>

A complete working sample can be downloaded from WindowStatus.zip.
