Coolite Toolkit学习笔记五:常用控件Menu和MenuPanel
Coolite Toolkit里的Menu控件和其他的.NET Web控件不一样,如果只是设计好了Menu或是通过程序初始化菜单项,菜单是不会呈现在界面上的,因为Coolite Toolkit规定Menu控件需要一个容器来做依托,而这个让Menu依托的控件就是MenuPanel,下面拖拽出的MenuPanel控件所生成的html编码:
从上面可以明显的看出,MenuPanel里可以放置菜单项(MenuItem),如果有子菜单,那么子菜单则对应于一个Menu控件,子菜单里的菜单项则又是通过菜单项(MenuItem)来体现。如下是我修改后的一个菜单html编码:
像Tree、Menu等类似的控件,我个人认为主要就是弄清楚他们内部的层次结构,不管是通过界面设计还是通过直接Code创建他们,最终得到的结果都是一样,如上菜单显示效果,同样可以通过如下程序代码来创建:

Code
从上面可以明显的看出,MenuPanel里可以放置菜单项(MenuItem),如果有子菜单,那么子菜单则对应于一个Menu控件,子菜单里的菜单项则又是通过菜单项(MenuItem)来体现。如下是我修改后的一个菜单html编码:
<ext:MenuPanel runat="server" Height="300" Title="帐套管理" Width="185">
<Menu runat="server">
<Items>
<ext:MenuItem runat="server" Text="新增帐套" Icon="Add">
<Listeners>
<Click Handler="JavaScript:window.location.href='#';" />
</Listeners>
</ext:MenuItem>
<ext:MenuItem runat="server" Text="维护帐套" Icon="Cmy"/>
<ext:MenuItem runat="server" Text="帐套管理" Icon="Database">
<Menu>
<ext:Menu runat="server">
<Items>
<ext:MenuItem runat="server" Text="备份帐套" Icon="DatabaseSave">
<Listeners>
<Click Handler="JavaScript:window.open('#');" />
</Listeners>
</ext:MenuItem>
<ext:MenuItem runat="server" Text="恢复帐套" Icon="DatabaseGo">
<Listeners>
<Click Handler="JavaScript:window.open('#');" />
</Listeners>
</ext:MenuItem>
</Items>
</ext:Menu>
</Menu>
</ext:MenuItem>
</Items>
<Listeners>
<ItemClick Fn="onItemClick" />
</Listeners>
</Menu>
</ext:MenuPanel>
<script type="text/javascript">
function onItemClick(menuItem) {
Ext.Msg.alert("★操作提示★", "当前点击项内容:" + menuItem.text);
}
</script>
<Menu runat="server">
<Items>
<ext:MenuItem runat="server" Text="新增帐套" Icon="Add">
<Listeners>
<Click Handler="JavaScript:window.location.href='#';" />
</Listeners>
</ext:MenuItem>
<ext:MenuItem runat="server" Text="维护帐套" Icon="Cmy"/>
<ext:MenuItem runat="server" Text="帐套管理" Icon="Database">
<Menu>
<ext:Menu runat="server">
<Items>
<ext:MenuItem runat="server" Text="备份帐套" Icon="DatabaseSave">
<Listeners>
<Click Handler="JavaScript:window.open('#');" />
</Listeners>
</ext:MenuItem>
<ext:MenuItem runat="server" Text="恢复帐套" Icon="DatabaseGo">
<Listeners>
<Click Handler="JavaScript:window.open('#');" />
</Listeners>
</ext:MenuItem>
</Items>
</ext:Menu>
</Menu>
</ext:MenuItem>
</Items>
<Listeners>
<ItemClick Fn="onItemClick" />
</Listeners>
</Menu>
</ext:MenuPanel>
<script type="text/javascript">
function onItemClick(menuItem) {
Ext.Msg.alert("★操作提示★", "当前点击项内容:" + menuItem.text);
}
</script>
像Tree、Menu等类似的控件,我个人认为主要就是弄清楚他们内部的层次结构,不管是通过界面设计还是通过直接Code创建他们,最终得到的结果都是一样,如上菜单显示效果,同样可以通过如下程序代码来创建:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
CreateMenuPanel();
}
}
private void CreateMenuPanel()
{
MenuPanel menuPanel = new MenuPanel();
menuPanel.Title = "帐套管理";
menuPanel.Width = new Unit(180);
Coolite.Ext.Web.MenuItem addAccount = new Coolite.Ext.Web.MenuItem("新增帐套");
addAccount.Icon = Icon.Add;
addAccount.Listeners.Click.Handler = "JavaScript:window.location.href='#';";
Coolite.Ext.Web.MenuItem whAccount = new Coolite.Ext.Web.MenuItem("维护帐套");
whAccount.Icon=Icon.Cmy;
Coolite.Ext.Web.MenuItem accountManage = new Coolite.Ext.Web.MenuItem("帐套管理");
accountManage.Icon = Icon.Database;
Coolite.Ext.Web.Menu subMenu = new Coolite.Ext.Web.Menu();
Coolite.Ext.Web.MenuItem backMenuItem = new Coolite.Ext.Web.MenuItem("备份帐套");
backMenuItem.Icon = Icon.DatabaseSave;
backMenuItem.Listeners.Click.Handler = "JavaScript:window.open('#')";
subMenu.Items.Add(backMenuItem);
Coolite.Ext.Web.MenuItem reMenuItem = new Coolite.Ext.Web.MenuItem("恢复帐套");
reMenuItem.Icon = Icon.DatabaseGo;
reMenuItem.Listeners.Click.Handler = "JavaScript:window.open('#')";
subMenu.Items.Add(reMenuItem);
accountManage.Menu.Add(subMenu);
menuPanel.Menu.Items.Add(addAccount);
menuPanel.Menu.Items.Add(whAccount);
menuPanel.Menu.Items.Add(accountManage);
menuPanel.Menu.Listeners.ItemClick.Fn = "onItemClick";
accountDiv.Controls.Add(menuPanel);
}
{
if (!IsPostBack)
{
CreateMenuPanel();
}
}
private void CreateMenuPanel()
{
MenuPanel menuPanel = new MenuPanel();
menuPanel.Title = "帐套管理";
menuPanel.Width = new Unit(180);
Coolite.Ext.Web.MenuItem addAccount = new Coolite.Ext.Web.MenuItem("新增帐套");
addAccount.Icon = Icon.Add;
addAccount.Listeners.Click.Handler = "JavaScript:window.location.href='#';";
Coolite.Ext.Web.MenuItem whAccount = new Coolite.Ext.Web.MenuItem("维护帐套");
whAccount.Icon=Icon.Cmy;
Coolite.Ext.Web.MenuItem accountManage = new Coolite.Ext.Web.MenuItem("帐套管理");
accountManage.Icon = Icon.Database;
Coolite.Ext.Web.Menu subMenu = new Coolite.Ext.Web.Menu();
Coolite.Ext.Web.MenuItem backMenuItem = new Coolite.Ext.Web.MenuItem("备份帐套");
backMenuItem.Icon = Icon.DatabaseSave;
backMenuItem.Listeners.Click.Handler = "JavaScript:window.open('#')";
subMenu.Items.Add(backMenuItem);
Coolite.Ext.Web.MenuItem reMenuItem = new Coolite.Ext.Web.MenuItem("恢复帐套");
reMenuItem.Icon = Icon.DatabaseGo;
reMenuItem.Listeners.Click.Handler = "JavaScript:window.open('#')";
subMenu.Items.Add(reMenuItem);
accountManage.Menu.Add(subMenu);
menuPanel.Menu.Items.Add(addAccount);
menuPanel.Menu.Items.Add(whAccount);
menuPanel.Menu.Items.Add(accountManage);
menuPanel.Menu.Listeners.ItemClick.Fn = "onItemClick";
accountDiv.Controls.Add(menuPanel);
}
