<asp:GridView ID="gvContentAssign1" runat="server" AutoGenerateColumns="false" AllowPaging="false" EmptyDataText="null" Width="100%" OnRowDataBound="gvRowDatabound" OnRowEditing="gvRowEditing"> <Columns> <asp:TemplateField HeaderText="<%$ resources:Section %>"> <ItemTemplate> <asp:Label ID="lbSection1" runat="server" style="font-size:14pt" Text="<%# Bind('SectionDesc2') %>"></asp:Label> </ItemTemplate> <ItemStyle Width="4%" /> <HeaderStyle Width="4%" /> </asp:TemplateField> </Columns> </asp:GridView>

别浪费时间了，这些操作应该用Jquery来做
jq总是拿不到控件的id,请问能教教我吗？
@rivahuang: 这个你看下Jq教程、视频就行了，拿控件ID是最简单的操作了
