gridview 固定表头，滚动在里面的，比前面的写的好看，css实现

这个grid写的有点乱了，主要的是外面的div，和里面的grid关系不是很大

<div id="div-gridview" style="height:520px;">
                                <asp:GridView ID="GridView1" runat="server" SkinID="AllowPage"  AllowPaging="false" Width="98%"
                                 OnPageIndexChanging="GridView1_PageIndexChanging" OnRowDeleting="GridView1_RowDeleting" AutoGenerateColumns="False"
                                  DataKeyNames="CountyId" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDataBound="GridView1_RowDataBound" 
                                  OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCommand="GridView1_RowCommand">
                                    <Columns>
                                        <asp:TemplateField>
                                        <HeaderTemplate>
                                            <asp:CheckBox ID="checkboxAll" runat="server" Text="全选" OnCheckedChanged="CheckAll" AutoPostBack="true" />
                                        </HeaderTemplate>
                                        <ItemStyle HorizontalAlign="Left" Width="50px" />
                                        <HeaderStyle HorizontalAlign="Left" Width="50px" />
                                        <ItemTemplate>
                                            <asp:CheckBox ID="checkboxDan" runat="server" />
                                            <asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("CountyId") %>' />
                                                <asp:HiddenField ID="HiddenField2" runat="server" Value='<%# Eval("IntId") %>' />
                                                <asp:HiddenField ID="HiddenField3" runat="server" Value='<%# Eval("BtsName") %>' />
                                                <asp:HiddenField ID="HiddenField4" runat="server" Value='<%# Eval("Lac") %>' />
                                                <asp:HiddenField ID="HiddenField5" runat="server" Value='<%# Eval("CellId") %>' />
                                                <asp:HiddenField ID="HiddenField6" runat="server" Value='<%# Eval("CellDesc") %>' />
                                        </ItemTemplate>
                                        </asp:TemplateField>
                                        <asp:BoundField DataField="CountyName" HeaderText="乡镇名">
                                            <ItemStyle Wrap="True" />
                                            <HeaderStyle Wrap="False" />
                                        </asp:BoundField>
                                        <asp:ButtonField CommandName="see" HeaderText="查看小区" Text="点击查看" />
                                        <asp:CommandField ShowEditButton="True" EditText="编辑" UpdateText="更新" CancelText="取消">
                                            <HeaderStyle Wrap="False" />
                                            <ItemStyle Wrap="False" />
                                        </asp:CommandField>
                                        <asp:CommandField ShowDeleteButton="True" DeleteText="删除">
                                            <HeaderStyle Wrap="False" />
                                            <ItemStyle Wrap="False" />
                                        </asp:CommandField>
                                    </Columns>
                                <PagerStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                                </asp:GridView></div>

再加上这个.css就ok了

其实里面只要有
div#div-gridview {
width: 100%;
height: 160px;
overflow: auto;
}
就可以了，但是为什么还有其他3个呢，因为有的时候页面要求多个gridview，这个时候你只写一个，其他的也会跟着动起来，所以写一个别的名，这样就不影响了
