在GridView中显示进度条的问题
想在GridView中显示进度条，进度数据存在绑定的xml中，如果按如下代码
<asp:TemplateField HeaderText="完成进度">
<ItemTemplate>
<img src='Image/progress.bmp' width='<%# 进度 %>'
height="10px" alt='<%# 进度 + "%" %>'>
</ItemTemplate>
</asp:TemplateField>
怎么从xml中得到进度值，然后能显示在上面代码中？或者有别的更好的办法在 GridView中显示进度？
谢谢了~~~~
[解决办法]
绑定XML采用
<%#XPath("XML节点")%>
如
以 XML 文件为数据源进行嵌套绑定
ASPX 代码
