</ItemTemplate>
<ItemStyleWidth="8%"HorizontalAlign="Center"/>
</asp:TemplateField>
</Columns>
</asp:GridView>

注意:

1、通过设置 ReadOnly="True" 表示此列不可以编辑;2、通过Text='<%# Bind("tzhysMoney", "{0:N2}") %>'进行金额格式化;3、重点的编辑\显示\合计

<asp:TemplateField>
<ItemTemplate>
<asp:LabelID="labtzhysMoney"runat="server"Text='<%#Bind("tzhysMoney","{0:N2}")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBoxID="txttzhysMoney"runat="server"Text='<%#Eval("tzhysMoney")%>'
Style="text-align:right"Width="100px"
></asp:TextBox>
</EditItemTemplate>
<ItemStyleWidth="8%"HorizontalAlign="right"/>
<FooterTemplate>
<asp:LabelID="labtotaltzhysMoney"runat="server"ForeColor="Red"></asp:Label>
</FooterTemplate>
<FooterStyleBorderColor="Black"HorizontalAlign="Right"/>
</asp:TemplateField>
