Examples

The following code example shows a Web Part with a custom property that uses HtmlDesignerAttribute to define a static custom builder.

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

namespace WebPartLibrary2
{
    
    [XmlRootAttribute(Namespace="WebPartLibrary2")]

    
    public class HtmlDesignerAttributeTestPart: WebPart
    {
        ///    Member variable for a property with 
        ///    HtmlDesignerAttribute defined for a custom builder
        private string customPropertyValue = "This Web Part has a custom property";
        
        /// <summary>
        ///        Use HtmlDesignerAttribute to define a static custom 
        ///        builder builder.aspx for the custom property.
        /// </summary>
        [WebPartStorage(Storage = Storage.Personal), 
        DefaultValue(""), 
        HtmlDesignerAttribute("http://myserver/builder.aspx")]
        public string CustomProperty
        {
            get
            {
                return customPropertyValue;
            }
            set
            {    
                customPropertyValue = value;
            }
        }
        
        /// <summary>
        ///        Renders the content of the HtmlDesignerAttributeTestPart.
        /// </summary>
        protected override void RenderWebPart (HtmlTextWriter output)
        {
            output.Write(SPEncode.HtmlEncode(CustomProperty));
        }
    }

}
