This is a quick tip. When getting started with ASP.NET MVC I used to have problems for example when I got some user input inside a textarea and wanted to show this text with the html <br /> tags instead of the system newlines. I couldn’t get it to work. The line breaks never used to display and the text displayed as one really long paragraph.
So I created this simple custom html helper that takes input from your source and properly formats it to show the line breaks. For lack of a better name, I called it FormatLines. Here’s the code.
public static class FormatLinesHelper
public static string FormatLines(this HtmlHelper helper, string stringToFormat)
StringBuilder sb = new System.Text.StringBuilder();
StringReader sr = new System.IO.StringReader(stringToFormat);
string buffer = null;
buffer = sr.ReadLine();
if (buffer != null)
} while (buffer != null);
Before you use it make sure to compile the code and import the namespace containing this helper method. You can do the import right in your target view like so …
<%@ Import Namespace=”WebUI.Helpers” %>
or include it in the web.config file under the namespaces section like so …
Use the helper anywhere in your view like so …
<%= Html.FormatLines (Html.Encode(Model.Notes)) %>
And your text will clearly be displayed with the new lines.
If you look at the source of the page, you’ll see the <br /> tags placed where your new lines used to be.
Hope this was helpful,
Till next time, yours truly.
