我们平时IEWebContr来做菜单时都是在html中直接输入,也就是说是静态的,现在要做成动态的,而且菜单级数不定,怎么来实现呢?笔者通过研究发现,用IEWebContr来做菜单时,菜单项可以直接输入,也可以用如下的方法指定从某一个文件中读取菜单项:
<iewc:TreeView runat="server" ID="Treeview1" NAME="Treeview1">
<iewc:TreeNode id="Treenode1" runat="server" TreeNodeSrc="menuone.txt" Expanded="True" Text="信息类别列表">
</iewc:TreeNode>
</iewc:TreeView>
其中menuone.txt的内容如下:
<TREENODES>
<treenode text=''蔬菜'' NavigateUrl=''xxcb_add.aspx?classname=蔬菜&classid=01''? Target=''main1''>
<treenode text=''白菜'' NavigateUrl=''xxcb_add.aspx?classname=白菜&classid=0101''?? Target=''main1''/>
<treenode text=''萝卜'' NavigateUrl=''xxcb_add.aspx?classname=萝卜&classid=0102''?? Target=''main1''/>
<treenode text=''黄花菜'' NavigateUrl=''xxcb_add.aspx?classname=黄花菜&classid=0103''?? Target=''main1''/>
</treenode>
<treenode text=''水果'' NavigateUrl=''xxcb_add.aspx?classname=水果&classid=02''? Target=''main1''>
<treenode text=''苹果'' NavigateUrl=''xxcb_add.aspx?classname=苹果&classid=0201''? Target=''main1''>
<treenode text=''红富士'' NavigateUrl=''xxcb_add.aspx?classname=红富士&classid=020101''?? Target=''main1''/>
<treenode text=''其它苹果'' NavigateUrl=''xxcb_add.aspx?classname=其它苹果&classid=020102''?? Target=''main1''/>
</treenode>
<treenode text=''桃子'' NavigateUrl=''xxcb_add.aspx?classname=桃子&classid=0202''?? Target=''main1''/>
<treenode text=''荔枝'' NavigateUrl=''xxcb_add.aspx?classname=荔枝&classid=0203''?? Target=''main1''/>
</treenode>
<treenode text=''粮食'' NavigateUrl=''xxcb_add.aspx?classname=粮食&classid=03''? Target=''main1''>
<treenode text=''大米'' NavigateUrl=''xxcb_add.aspx?classname=大米&classid=0301''?? Target=''main1''/>
<treenode text=''玉米'' NavigateUrl=''xxcb_add.aspx?classname=玉米&classid=0302''?? Target=''main1''/>
</treenode>
</TREENODES>
