再看一下原先的前台代码

<ItemTemplate>
 <asp:Button ID=”Button3″ runat=”server” CausesValidation=”False”
CommandArgument=”<%# Container.DataItemIndex %>”
CommandName=”Entry” Text=”入库” OnClientClick=”return confirm(‘确认要将此钢轮移出备用库放入当前使用库吗？’)”/>
 </ItemTemplate>
 </asp:TemplateField>

最后看一下改进后的代码

<ItemTemplate>
 <asp:Button ID=”Button3″ runat=”server” CausesValidation=”False”
CommandArgument=”<%# ((GridViewRow) Container).RowIndex %>”
CommandName=”Entry” Text=”入库” OnClientClick=”return confirm(‘确认要将此钢轮移出备用库放入当前使用库吗？’)”/>
</ItemTemplate>
</asp:TemplateField>

其实就是为了说明一个问题：

如果用Container.DataItemIndex 在后台代码中得到的是这一数据行在这个数据表中的序列，如果此Gridview不分页的话，用起来没有任何问题，如果分页的话，就不行了。如我们操作的是第二页的第二条记录，得到的序列是 11 ，即 idx =11 ,而我期望的是1.

如果用((GridViewRow) Container).RowIndex 那 idx=1; 即这一行代码得到的是此数据行在当前Gridview页面中的序列，如果PageSize=10的话，那idx 最大为9，最小为0.

今天项目中用到的，特别记录一下.

    .table_break
    {
        word-break :normal ; word-wrap:break-word;
    }   

2.引用这个CSS

 ItemStyle-Width=”80px” ItemStyle-CssClass=”table_break”

注意：既然是固定列宽，当然要指定宽度啦。
