浅谈DevExpress<一>：换肤

　　最近要用到devExpress，一句话，很好很强大，比起vs自带的winform界面，种类和花样要多了不少，然而，强力的功能带来了庞大的信息量，所以我打算通过一些小模块来和大家一起对它进行探讨和研究。

　　今天先研究一下他的换肤功能。在控件中，其默认提供了18中风格让我们选择，如下图：

　　下面就看看怎么实现让界面切换到选中风格的功能。先建立一个项目，引入一个button和一个grid如下图：

　　由于在devExpress.skins.skinManager.Default.Skins中只有13中皮肤所以我们要手动添加5种，找到Designer.cs文件，添加下列代码：

         this.iPaintStyle.CategoryGuid = new System.Guid("d0173875-bf7b-4740-b252-5047db62606c");
        
            this.iPaintStyle.LinksPersistInfo.AddRange(new DevExpress.XtraBars.LinkPersistInfo[] {
            new DevExpress.XtraBars.LinkPersistInfo(this.ipsDefault),
            new DevExpress.XtraBars.LinkPersistInfo(this.ipsWXP),
            new DevExpress.XtraBars.LinkPersistInfo(this.ipsOXP),
            new DevExpress.XtraBars.LinkPersistInfo(this.ipsO2K),
            new DevExpress.XtraBars.LinkPersistInfo(this.ipsO3)});

　　　　 private DevExpress.XtraBars.BarButtonItem ipsWXP;
        private DevExpress.XtraBars.BarButtonItem ipsOXP;
        private DevExpress.XtraBars.BarButtonItem ipsO2K;
        private DevExpress.XtraBars.BarButtonItem ipsO3;
        private DevExpress.XtraBars.BarButtonItem ipsDefault;


        this.ipsDefault = new DevExpress.XtraBars.BarButtonItem();
        this.ipsWXP = new DevExpress.XtraBars.BarButtonItem();
        this.ipsOXP = new DevExpress.XtraBars.BarButtonItem();
        this.ipsO2K = new DevExpress.XtraBars.BarButtonItem();
        this.ipsO3 = new DevExpress.XtraBars.BarButtonItem();


            // 
            // ipsDefault
            // 
            this.ipsDefault.Caption = "Default";
            this.ipsDefault.CategoryGuid = new         System.Guid("d0173875-    bf7b-4740-b252-5047db62606c");
            this.ipsDefault.Description = "Default";
            this.ipsDefault.Id = 15;
            this.ipsDefault.Name = "ipsDefault";
            this.ipsDefault.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(this.ips_ItemClick);
            // 
            // ipsWXP
            // 
            this.ipsWXP.Caption = "Windows XP";
            this.ipsWXP.CategoryGuid = new System.Guid("d0173875-bf7b-4740-b252-5047db62606c");
            this.ipsWXP.Description = "WindowsXP";
            this.ipsWXP.Id = 11;
            this.ipsWXP.ImageIndex = 5;
            this.ipsWXP.Name = "ipsWXP";
            this.ipsWXP.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(this.ips_ItemClick);
            // 
            // ipsOXP
            // 
            this.ipsOXP.Caption = "Office XP";
            this.ipsOXP.CategoryGuid = new System.Guid("d0173875-bf7b-4740-b252-5047db62606c");
            this.ipsOXP.Description = "OfficeXP";
            this.ipsOXP.Id = 12;
            this.ipsOXP.ImageIndex = 3;
            this.ipsOXP.Name = "ipsOXP";
            this.ipsOXP.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(this.ips_ItemClick);
            // 
            // ipsO2K
            // 
            this.ipsO2K.Caption = "Office 2000";
            this.ipsO2K.CategoryGuid = new System.Guid("d0173875-bf7b-4740-b252-5047db62606c");
            this.ipsO2K.Description = "Office2000";
            this.ipsO2K.Id = 13;
            this.ipsO2K.ImageIndex = 4;
            this.ipsO2K.Name = "ipsO2K";
            this.ipsO2K.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(this.ips_ItemClick);
            // 
            // ipsO3
            // 
            this.ipsO3.Caption = "Office 2003";
            this.ipsO3.CategoryGuid = new System.Guid("d0173875-bf7b-4740-b252-5047db62606c");
            this.ipsO3.Description = "Office2003";
            this.ipsO3.Id = 14;
            this.ipsO3.ImageIndex = 6;
            this.ipsO3.Name = "ipsO3";
            this.ipsO3.ItemClick += new DevExpress.XtraBars.ItemClickEventHandler(this.ips_ItemClick);                    

　　然后将其添加到barManager的项中

　　

 this.barManager1.Items.AddRange(new DevExpress.XtraBars.BarItem[] {
            this.barSubItem1,
            this.barSubItem2,
            this.ipsWXP,
            this.ipsOXP,
            this.ipsO2K,
            this.ipsO3,
            this.ipsDefault,
            this.iPaintStyle});

　　然后添加这几种风格的点击事件

private void ips_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            barManager1.GetController().PaintStyleName = e.Item.Description;
            InitPaintStyle(e.Item);
            barManager1.GetController().ResetStyleDefaults();
            DevExpress.LookAndFeel.UserLookAndFeel.Default.SetDefaultStyle();
        }

　　然后将皮肤初始化并为其注册选择事件

  private void iPaintStyleStyle_Init()
        {
            BarItem item = null;
            for (int i = 0; i < barManager1.Items.Count; i++)
            {
                if (barManager1.Items[i].Description == barManager1.GetController().PaintStyleName)
                    item = barManager1.Items[i];
            }
            InitPaintStyle(item);
        }

        private void InitPaintStyle(BarItem item)
        {
            if (item == null)
            {
                iPaintStyle.ImageIndex = item.ImageIndex;
                iPaintStyle.Caption = item.Caption;
                iPaintStyle.Hint = item.Description;
            }
        }

        void InitSkins()
        {
            barManager1.ForceInitialize();
            foreach (DevExpress.Skins.SkinContainer cnt in DevExpress.Skins.SkinManager.Default.Skins)
            {
                BarButtonItem item = new BarButtonItem(barManager1, skinMask + cnt.SkinName);
                iPaintStyle.AddItem(item);
                item.ItemClick += new ItemClickEventHandler(OnSkinClick);

            }
        }

        void OnSkinClick(Object sender, ItemClickEventArgs e)
        {
            string skinName = e.Item.Caption.Replace(skinMask, "");
            DevExpress.LookAndFeel.UserLookAndFeel.Default.SetSkinStyle(skinName);
            barManager1.GetController().PaintStyleName = "Skin";
            iPaintStyle.Caption = iPaintStyle.Hint = e.Item.Caption;
            iPaintStyle.Hint = iPaintStyle.Caption;
            iPaintStyle.ImageIndex = -1;
        }

　　大功告成：初始化winform的时候调用下面两个方法就可以进行换肤了

         iPaintStyleStyle_Init();
            InitSkins();

　　效果如下：

　　上面的是比较麻烦的办法，我们也可以用他自身集成的换肤功能来实现这一效果：在winform中拉一个ribbonControl控件，在page页中添加ribbonGalleryBarItem。

　　然后加入引用

using DevExpress.XtraBars.Helpers;

　　在窗口加载时让刚添加的item设置为皮肤选项：

    　　 private void Form1_Load(object sender, EventArgs e)
        {
            SkinHelper.InitSkinGallery(ribbonGalleryBarItem1);
            this.ribbonControl1.ToolbarLocation = DevExpress.XtraBars.Ribbon.RibbonQuickAccessToolbarLocation.Hidden;
        }

　　这样就可以实现下面的效果了：
