I'm trying to generate a HTML document with RazorEngine (http://razorengine.codeplex.com/). Everything is mostly working, but the problem I have now is some of the HTML is being rendered correctly, and HTML that I have nested in that is being rendered as literal HTML, so rather than the browser displaying the tables & divs as expected, it's displaying e.g.
"<table></table><div></div>"
I kick off this process by calling the following:
string completeHTML = RazorEngine.Razor.Parse("InstallationTemplate.cshtml", new { Data = viewModels });
The completeHTML is then written to a file.
"InstallationTemplate.cshtml" is defined as:
@{
var installationReport = new InstallationReport(Model.Data);
}
<!DOCTYPE html>
<html>
<head></head>
<body>
<div>
<!-- I would expect this to write the rendered HTML
in place of "@installationReport.DigiChannels()" -->
@installationReport.DigiChannels()
</div>
</body>
</html>
Where InstallationReport and DigiChannels are defined as follows:
public static class InstallationReportExtensions
{
public static string DigiChannels(this InstallationReport installationReport)
{
return installationReport.GetDigiChannelsHtml();
}
}
public class InstallationReport
{
public string GetDigiChannelsHtml()
{
// the following renders the template correctly
string renderedHtml = RazorReport.GetHtml("DigiChannels.cshtml", GetDigiChannelData());
return renderedHtml;
}
}
public static string GetHtml(string templateName, object data)
{
var templateString = GetTemplateString(templateName);
return RazorEngine.Razor.Parse(templateString, data);
}
After GetDigiChannelsHtml() runs and returns renderedHtml, the line of execution returns to TemplateBase.cs into the method ITemplate.Run(ExecuteContext context), which is defined as:
string ITemplate.Run(ExecuteContext context)
{
_context = context;
var builder = new StringBuilder();
using (var writer = new StringWriter(builder))
{
_context.CurrentWriter = writer;
Execute(); // this is where my stuff gets called
_context.CurrentWriter = null;
}
if (Layout != null)
{
// Get the layout template.
var layout = ResolveLayout(Layout);
// Push the current body instance onto the stack for later execution.
var body = new TemplateWriter(tw => tw.Write(builder.ToString()));
context.PushBody(body);
return layout.Run(context);
}
return builder.ToString();
}
When I inspect builder.ToString(), I can see it contains proper HTML for the InstallationTemplate.cshtml stuff, and escaped HTML for the DigiChannels.cshtml stuff. For example:
How can I get @installationReport.DigiChannels() to include the correct HTML instead of the escaped HTML that it's currently doing?
