WebPart引用UserControl

Webpart引用UserControl有两种方法：

1. 引用QuickPart

2. 自己开发出一个WebPart暴露一个引用地址属性。代码如下：

using System;
using System.Runtime.InteropServices;
using System.Web.UI;
using System.Web.UI.WebControls.WebParts;



namespace WebPartCollection
{
    [Guid("1c7e7f5f-c4d6-4628-8785-3804bc0f5c85")]
    public class UserControlWebPart : System.Web.UI.WebControls.WebParts.WebPart
    {
        public UserControlWebPart()
        {
            
        }

        private string _ControlPath;
        [Personalizable]
        [WebBrowsable]
        [WebDisplayName("Control File Path")]
        public string ControlPath
        {
            get { return _ControlPath; }
            set { _ControlPath = value; }
        }
        protected override void CreateChildControls()
        {

            base.CreateChildControls();

        }
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            if (string.IsNullOrEmpty(_ControlPath))
               return ;
            try
            {
                Control calendar = Page.LoadControl(_ControlPath);
                if (calendar!=null)
                {
                    this.Controls.Add(calendar);
                }
            }
            catch (Exception ex)
            {
                this.Controls.Add(new LiteralControl(ex.Message));
            }
        }
    }
}

ControlPath的地址格式如下：~/_CONTROLTEMPLATES/Calendar.ascx，从以上的地址格式可以看出Calendar.ascx文件是放在12\TEMPLATE\CONTROLTEMPLATES文件夹里面。
