winform 实现类似我们VS工具工具箱那样 对控件分组。

点击一个栏目 出现该栏目下所以内容。类似我们 VS 工具箱那样的效果。。


怎么实现

就是菜单进行分组吧~~

[fengjian_428]

普通菜单效果不好 用第三方吧

[程序漫步]

能推荐下吗~

[TTOJJ]

1.可以直接分組的控件有listView，treeView
2.像qq一樣的分組：自己用BUTTON或者PANEL寫一個，可以用location貨dock來改變
3.自己寫控件，其實很簡單的，DOWNLOAD點資料就ok了
4.第三方調用，比如DevComponents

[程序漫步]

继续~

我也顺便问下，如果自己写。
每个panle或button下的那些图标，是放到一个form里，点的时候加载
还是怎么做的

重写treeview控件可以实现。

这是我用过的。你自己可以修改一下

[sugarche]

还有两个资源文件，一个加号图片（IconResource.expanded），一个减号图片（IconResource.collapsed）。你自己做两张图片加进去

lz 这有你想要的控件 分享一下 免费下载的哦！！！


嘿嘿…… 记得给我点分哦！http://www.dotnetmagic.com/downloads/Magic174AndKrypton.zip

哎呦，理解错了lz的意思了 ！
还是用NavBarControl吧 忘了那有下载的啦 ！
