本文实例讲述了asp.net中GridView编辑,更新,合计用法。分享给大家供大家参考，具体如下：

前台代码:

<asp:GridView ID="tabgv" runat="server" DataKeyNames="ysId" ShowFooter="True" OnRowDataBound="GridView1_RowDataBound"
  OnRowCreated="GridView1_RowCreated" AutoGenerateColumns="False" Width="99%" CssClass="gridview"

  OnRowUpdating="tabgv_RowUpdating">

    <asp:TemplateField HeaderText="备注">
      <ItemTemp【文章出处http://www.nextecloud.cn/kt.html欢迎转载】late>
        <asp:Label ID="labtremark" runat="server" Text='<%# Eval("remark") %> '></asp:Label>
      </ItemTemplate>
      <EditItemTemplate>
        <asp:TextBox ID="txtremark" runat="server" Text='<%# Eval("remark") %> ' Width="100px"></asp:TextBox>
      </EditItemTemplate>
      <ItemStyle Width="10%" HorizontalAlign="Center" />
    </asp:TemplateField>
    <asp:TemplateField ShowHeader="False">
      <EditItemTemplate>
        <asp:LinkButton ID="LkBtnUpdate" runat="server" CausesValidation="True" CommandName="Update"
          Text="更新"></asp:LinkButton>
        <asp:LinkButton ID="LkBtnCtrl" runat="server" CausesValidation="False" CommandName="Cancel"
          Text="取消"></asp:LinkButton>
      </EditItemTemplate>
      <ItemTemplate>
        <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName='<%#Eval("childFlag").ToString()== "0" ? "":"Edit"%>'
          Text='<%#Eval("childFlag").ToString()== "0" ? "锁定":"编辑"%>'></asp:LinkButton>
      </ItemTemplate>
      <ItemStyle Width="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:Label ID="labtzhysMoney" runat="server" Text='<%# Bind("tzhysMoney", "{0:N2}") %>'></asp:Label>
  </ItemTemplate>
  <EditItemTemplate>
    <asp:TextBox ID="txttzhysMoney" runat="server" Text='<%# Eval("tzhysMoney") %> '
      Style="text-align: right" Width="100px"
       ></asp:TextBox>
  </EditItemTemplate>
  <ItemStyle Width="8%" HorizontalAlign="right" />
  <FooterTemplate>
    <asp:Label ID="labtotaltzhysMoney" runat="server" ForeColor="Red"></asp:Label>
  </FooterTemplate>
  <FooterStyle BorderColor="Black" HorizontalAlign="Right" />
</asp:TemplateField>

后台代码:

行绑定时的操作:
