Render html in a reportviewer textbox

Starting with Visual Studio 2010, the included Microsoft ReportViewer control (ReportViewer v10) supports the rendering of HTML inside a textbox. With this functionality, you can use multiple styles inside one textbox.

The supported text format tags you can use are the following: <B>, <I>, <U>, <S>.

The default behaviour the textbox uses is to render plain text, but it’s very easy to activate the html rendering on a specific textbox containing a placeholder:

1. Starting situation: a textbox with placeholder
   
   (You can easily add a placeholder by dragging it from the datasource window to a specific textbox)
2. Select the placeholder by clicking on it
   
3. Right click the selected placeholder and select ‘Placeholder properties’.
   
4. A property window opens:
   
5. In the general tab, switch the rendering to HTML:
   
6. Now save your report and the HTML text you pass to the placeholder will be rendered correctly.
