Using BBCode with C1EditorExtender

The C1EditorExtender control supports BBCode, or Bulletin Board Code, which is a markup language used to format posts in message boards. Simply set the Mode property to take advantage of this feature.

<wijmo:C1EditorExtender ID="EditorExtender1" runat="server" TargetControlID="TextBox1" Mode="Bbcode" />

Create an ASP.NET Web application.
Add a standard TextBox control to the main content of your page.
Resize the TextBox to make it larger, set the TextMode property to MultiLine, and enter some content. For example, use the following XAML markup:

<asp:TextBox ID="TextBox1" runat="server" Height="264px" TextMode="MultiLine" Width="415px">This is some [B]sample text[/B]. You can visit [URL=http://componentone.com/]C-ONE[/URL].</asp:TextBox>

Click the TextBox smart tag and select Add Extender from the Tasks menu.
In the Extender Wizard, select C1EditorExtender and click OK. A C1EditorExtender control is added to the page and the TargetControlID is set to TextBox1.
Select View | Properties Window in the Visual Studio menu.
Click the drop-down list at the top of the Properties window and select TextBox1_C1EditorExtender.
Set the C1EditorExtender.Mode property to Bbcode. Your markup should look similar to this:

<wijmo:C1EditorExtender ID="EditorExtender1" runat="server" TargetControlID="TextBox1" Mode="Bbcode" />

Press F5 to run the application. The editor displays the BBCode formatted content.
