GridVie问题

Question

固定区域，样式一样，把第二列和第三列对换后，本来能显示16条的区域现在只显示15条，本来没有滚动条的现在也有了。这是什么原因啊。<asp:GridView ID="gv" runat="server" RowStyle-ForeColor="Black"
                            Width="100%" AutoGenerateColumns="False" CellPadding="2" 
                            OnRowDataBound="gv_RowDataBound" Font-Size="9pt">
                            <RowStyle HorizontalAlign="Center" VerticalAlign="Middle"
                                Font-Size="9pt"></RowStyle>
                            <Columns>
                                <asp:BoundField DataField="No" HeaderText="点位机ID">
                                    <HeaderStyle CssClass="gvHeader" Height="9px" Width="25%"/>
                                    <ItemStyle CssClass="gvItem" Height="9px" Width="25%" />
                                </asp:BoundField>
                                <asp:BoundField DataField="vcPacker" HeaderText="包装员">
                                    <HeaderStyle CssClass="gvHeader" Height="9px" Width="25%"  />
                                    <ItemStyle CssClass="gvItem" Height="9px" Width="25%" />
                                </asp:BoundField>
                                <asp:BoundField DataField="vcState" HeaderText="状态">
                                    <HeaderStyle CssClass="gvHeader" Height="9px" Width="25%" />
                                    <ItemStyle CssClass="gvItem" Height="9px" Width="25%"/>
                                </asp:BoundField>
                                <asp:TemplateField HeaderText="图片">
                                    <ItemTemplate>
                                        <asp:Image ID="ImageLight" runat="server" />
                                    </ItemTemplate>
                                    <HeaderStyle CssClass="gvHeader" Height="9px" Width="25%"  />
                                    <ItemStyle CssClass="gvItem" Height="9px" Width="25%"  />
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>

Answer 1

上面的显示15条 带滚动条
下面的16条正好不带滚动条<asp:GridView ID="gv" runat="server" RowStyle-ForeColor="Black"
                            Width="100%" AutoGenerateColumns="False" CellPadding="2"

                            <RowStyle HorizontalAlign="Center" VerticalAlign="Middle"
                                Font-Size="9pt"></RowStyle>
                            <Columns>
                                <asp:BoundField DataField="No" HeaderText="点位机ID">
