CnForum换服技术

 1.基类

public abstract class SkinnedForumWebControl : Control, INamingContainer 
    {

        string skinFilename = null;
        public string SkinFilename 
        {
            get 
            { 
                return skinFilename; 
            }
            set 
            { 
                skinFilename = value; 
            }
        }


        public SkinnedForumWebControl() 
        {          

        }

        protected override void CreateChildControls() 
        {
            Control skin = null;

            skin = LoadSkin();

            InitializeSkin(skin);

            Controls.Add(skin);
        }


        protected Control LoadSkin() 
        {
            Control skin;
            string skinPath = Globals.GetSkinPath() + "/Skins/" + SkinFilename.TrimStart('/');        
            
            skin = Page.LoadControl(skinPath);          

            return skin;
        }


        protected abstract void InitializeSkin(Control skin);

    }

2.具体个体类

public class ThreadView : SkinnedForumWebControl 
        {
            string skinFilename              = "View-Threads.ascx";

            Button sortButton;
        
       
            public ThreadView() 
            {
                if (SkinFilename == null)
                    SkinFilename = skinFilename;
            }

            protected override void InitializeSkin(Control skin) 
            {
                sortButton = (Button) skin.FindControl("SortThreadsButton");
                if (sortButton != null) 
                {
                    sortButton.Text = ResourceManager.GetString("ViewThreads_SortThreads");
                    sortButton.Click += new EventHandler(Sort_Changed);
                }
                DataBind();
            }

            Events#region Events
            public void Sort_Changed (Object sender, EventArgs e) 
            {                
                DataBind();
            }            
            #endregion

            Databinding#region Databinding
            public override void DataBind() 
            {
            
            }
            #endregion
        }

3.提供皮肤页面View-Threads.ascx

4.控件的使用

<Forums:ThreadView  runat="server"/>
