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" EnableModelValidation="True" OnRowCancelingEdit="tabgv_RowCancelingEdit" OnRowEditing="tabgv_RowEditing" OnRowUpdating="tabgv_RowUpdating"> <RowStyle BorderColor="Black" BorderStyle="None" /> <Columns> <asp:BoundField DataField="gsHkrno" HeaderText="项目编号" ReadOnly="True"> <ItemStyle Width="5%" HorizontalAlign="Center" /> <FooterStyle BorderWidth="0px" /> </asp:BoundField> <asp:TemplateField HeaderText="项目名称"> <ItemTemplate> <asp:HyperLink ID="Hyp_gsName" runat="server" ForeColor="Blue" Text='<%# Bind("gsName") %>'></asp:HyperLink> </ItemTemplate> <ItemStyle Width="25%" HorizontalAlign="left" /> <FooterTemplate> <asp:Label ID="Label4" runat="server" Font-Bold="True" Text="合 计：" Width="61px"></asp:Label> </FooterTemplate> <FooterStyle BorderColor="Black" BorderWidth="0px" HorizontalAlign="Right" /> </asp:TemplateField> <asp:TemplateField HeaderText="概算金额"> <ItemTemplate> <asp:Label ID="labgsMoney" runat="server" Text='<%#Bind("gsMoney", "{0:N2}") %>'></asp:Label> </ItemTemplate> <ItemStyle Width="8%" HorizontalAlign="right" /> <FooterTemplate> <asp:Label ID="labtotalgsMoney" runat="server" ForeColor="Red"></asp:Label> </FooterTemplate> <FooterStyle BorderColor="Black" HorizontalAlign="Right" /> </asp:TemplateField> <asp:TemplateField HeaderText="开工至上年底n累计完成概算"> <ItemTemplate> <asp:Label ID="labkgzsndwcGsMoney" runat="server" Text='<%# Bind("footMoney", "{0:N2}") %>'></asp:Label> <asp:HiddenField ID="hdnysYear" runat="server" Value='<%# Eval("ysYear") %> ' /> <asp:HiddenField ID="hdngsId" runat="server" Value='<%# Eval("gsId") %> ' /> <asp:HiddenField ID="hdngsHkrno" runat="server" Value='<%# Eval("gsHkrno") %> ' /> <asp:HiddenField ID="hdnChildFlag" runat="server" Value='<%# Eval("childFlag") %> ' /> </ItemTemplate> <ItemStyle Width="8%" HorizontalAlign="right" /> <FooterTemplate> <asp:Label ID="labtotalfootMoney" runat="server" ForeColor="Red"></asp:Label> </FooterTemplate> <FooterStyle BorderColor="Black" HorizontalAlign="Right" /> </asp:TemplateField> <asp:TemplateField HeaderText="投资计划金额"> <ItemTemplate> <asp:Label ID="labtzqysMoney" runat="server" Text='<%# Bind("tzqysMoney", "{0:N2}") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txttzqysMoney" runat="server" Text='<%# Eval("tzqysMoney") %> ' Width="100px" onKeyPress="if (event.keyCode!=46 && event.keyCode!=45 && (event.keyCode<48 || event.keyCode>57)) event.returnValue=false"></asp:TextBox> </EditItemTemplate> <ItemStyle Width="8%" HorizontalAlign="right" /> <FooterTemplate> <asp:Label ID="labtotaltzqysMoney" runat="server" ForeColor="Red"></asp:Label> </FooterTemplate> <FooterStyle BorderColor="Black" HorizontalAlign="Right" /> </asp:TemplateField> <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") %> ' Width="100px" onKeyPress="if (event.keyCode!=46 && event.keyCode!=45 && (event.keyCode<48 || event.keyCode>57)) event.returnValue=false"></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> <asp:TemplateField HeaderText="备注"> <ItemTemplate> <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" "%>' Text='<%#Eval("childFlag").ToString()== "0" "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") %> ' 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:
