本文實例講述了asp.net中GridView編輯,更新,合計用法。分享給大家供大家參考，具體如下：

ItemStyle Width="8%" HorizontalAlign="right" />
FooterTemplate>
asp:Label ID="labtotaltzqysMoney" runat="server" ForeColor="Red">/asp:Label>
/FooterTemplate>
FooterStyle BorderColor="Black" HorizontalAlign="Right" />

/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"

/EditItemTemplate>
ItemTemplate>
asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName='%#Eval("childFlag").ToString()== "0" ? "":"Edit"%>'
Text='%#Eval("childFlag").ToString()== "0" ? "鎖定":"編輯"%>'>/asp:LinkButton>
/ItemTemplate>
ItemStyle Width="8%" HorizontalAlign="Center" />
/asp:TemplateField>
/Columns>
/asp:GridView>
注意:
1、通過設(shè)置 ReadOnly="True" 表示此列不可以編輯;
2、通過Text='%# Bind("tzhysMoney", "{0:N2}") %>'進行金額格式化;
3、重點的編輯\顯示\合計

后臺代碼:
行綁定時的操作:

if (hdnChildFlag.Value!="1")

//設(shè)置連接地址\參數(shù)
hy.NavigateUrl = "ys_edit_right.aspx?gsHkrno=" + hdngsHkrno.Value + "sysObjNo=" + sysObjNo + "ysYear=" + hdnysYear.Value;
