怎么总=“sum"For templatecolumcolumns In RadGrid (Telerik)

本文关键字：In templatecolumcolumns For RadGrid Telerik quot sum | 更新日期: 2023-09-27 18:02:19

my templateccolumn In RadGrid (Telerik)如下所示:

                    <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Benefit"
                        HeaderText="Benefit" UniqueName="TemplateColumn_Benefit" FilterImageToolTip="Filter">
                        <ItemTemplate>
                            <asp:Label ID="lblBenefitInsideGrd" runat="server" Font-Size="11px" Text='<%# (bool)Convert.IsDBNull(Eval("Benefit")) ? "<span class='"lblInsideGrd'">Empty</span>" : String.Format("{0:#,0 Dollar;#,0- Dollar}", Eval("Benefit")) %>'></asp:Label>
                        </ItemTemplate>
                        <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
                        <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
                    </telerik:GridTemplateColumn>

RadGrid的showfooter属性是true…
当将下面的属性添加到这个模板列时，我们将会有一个异常…

properties: FooterText="my sum"总="Sum"

错误消息:类型"System.Object"不支持Sum

如何在radgrid中得到这些列的和?

thanks in advance

您必须将DataField="Benefit"添加到gridtemplatecoluml 

               <telerik:GridTemplateColumn FilterControlAltText="Filter TemplateColumn_Benefit" DataField="Benefit"
                    HeaderText="Benefit" UniqueName="TemplateColumn_Benefit" FilterImageToolTip="Filter">
                    <ItemTemplate>
                        <asp:Label ID="lblBenefitInsideGrd" runat="server" Font-Size="11px" Text='<%# (bool)Convert.IsDBNull(Eval("Benefit")) ? "<span class='"lblInsideGrd'">Empty</span>" : String.Format("{0:#,0 Dollar;#,0- Dollar}", Eval("Benefit")) %>'></asp:Label>
                    </ItemTemplate>
                    <HeaderStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
                    <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="60px" />
                </telerik:GridTemplateColumn>
