篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Devexpress 中对RedailMenu的使用相关的知识，希望对你有一定的参考价值。
最近项目中用到RadialMenu，效果图如下所示：(图片因为公司要求不能挂出来，所以截取中一部分了)
闲下来就对，devexpress中的RedialMenu的使用总结一下。
第一：假设RedialMenu中全部是BarButtonItem的情况。
第二：假设RedialMenu中有BarSubItem也有BarButtonItem的情况。
第三：假设先按首字母进行归类，首字母全部为BarSubItem,其中的子类为BarButtonItem。
第一中情况的效果图如下所示
调用代码：
radialMenu.InitDate(barManager, 9, ItemClick, this); radialMenu.AddSubItemAndItem(list);
其中红色字体list是初始化数据：
List<string> list = new List<string>(); for (int i = 1; i <= 5; i++) { list.Add("啊受命于天" + i); } for (int i = 1; i <= 6; i++) { list.Add("吧受命于天" + i); } for (int i = 1; i <= 7; i++) { list.Add("才受命于天" + i); } for (int i = 1; i <= 8; i++) { list.Add("的受命于天" + i); } for (int i = 1; i <= 9; i++) { list.Add("额受命于天" + i); } for (int i = 1; i <= 10; i++) { list.Add("飞受命于天" + i); } for (int i = 1; i <= 11; i++) { list.Add("个受命于天" + i); } for (int i = 1; i <= 12; i++) { list.Add("好吧受命于天" + i); } for (int i = 1; i <= 13; i++) { list.Add("就才受命于天" + i); } for (int i = 1; i <= 14; i++) { list.Add("看的受命于天" + i); } for (int i = 1; i <= 15; i++) { list.Add("了额受命于天" + i); } for (int i = 1; i <= 16; i++) { list.Add("吗飞受命于天" + i); } for (int i = 1; i <= 17; i++) { list.Add("你受命于天" + i); } for (int i = 1; i <= 18; i++) { list.Add("哦吧受命于天" + i); } for (int i = 1; i <= 19; i++) { list.Add("平才受命于天" + i); } for (int i = 1; i <= 20; i++) { list.Add("去的受命于天" + i); } for (int i = 1; i <= 21; i++) { list.Add("人额受命于天" + i); } for (int i = 1; i <= 22; i++) { list.Add("是飞受命于天" + i); } for (int i = 1; i <= 23; i++) { list.Add("他才受命于天" + i); } for (int i = 1; i <= 24; i++) { list.Add("我的受命于天" + i); } for (int i = 1; i <= 25; i++) { list.Add("想受命于天" + i); } for (int i = 1; i <= 26; i++) { list.Add("一飞受命于天" + i); } for (int i = 1; i <= 27; i++) { list.Add("在飞受命于天" + i); }
第二中情况的效果图如下所示
调用代码：
List<string> list = new List<string>(); Dictionary<string, List<string>> dic = new Dictionary<string, List<string>>(); for (int i = 0; i < 10; i++) { list.Clear(); for (int j = 0; j <= i + 5; j++) { list.Add("受命于天" + j); } if (i % 5 == 0) list.Clear(); dic["受命于天" + i] = new List<string>(list); } radialMenu.InitDate(barManager, 10, ItemClick, this); radialMenu.AddSubItemAndItem(dic);
第三中情况的效果图如下所示
按汉子首字母拼英进行归类，其中的子项归为首字母中。
调用代码：
radialMenu.InitDate(barManager, 9, ItemClick, this); radialMenu.AddSubItemAndItem(list);
代码中的list与第一种情况下的list一样。
新建RadialMenu的扩展方法InitDate和AddSubItemAndItem。代码如下所示：
