Developing Custom Properties for the Web Part

In NavigationWebPart.cs, we’ll remove some additional code that has been added by the template before we create our properties. Remove all the generated comments and the following:

private const string defaultText = "";

private string text = defaultText;

[Browsable(true),
 Category("Miscellaneous"),
 DefaultValue(defaultText),
 WebPartStorage(Storage.Personal),
 FriendlyName("Text"),
 Description("Text Property")]
public string Text
{
  get
  {
    return text;
  }
  set
  {
    text = value;
  }
}

Also remove this auto-generated line from the RenderWebPart() method:

Output.Write(SPEncode.HtmlEncode(Text));

Then add the import for the System.Web namespace, and NavigationWebPart.cs should now look like this:

using System;
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Xml.Serialization;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint...
