Question

您好我有一个名为“OrderedQty”的asp绑定域和一个asp文本框（txtDeliveredQty）的gridview，其中用户输入已交付数量的数量。如何使用comparevalidator来阻止用户输入低于OrderedQty的数字（整数）的验证？

以下是我使用此过滤优先级的代码：

<asp:BoundField DataField="Qty" HeaderText="Ordered" SortExpression="Qty"></asp:BoundField>
                            <asp:TemplateField HeaderText="Delivered Qty">
                                <ItemTemplate>
                                    <asp:TextBox ID="txtNewQty" runat="server" CssClass="form-control" Width="100" TextMode="Number" Min="1"></asp:TextBox>
                                    <asp:RangeValidator ID="RangeValidator1" runat="server" ErrorMessage="Please enter a valid number" ControlToValidate="txtNewQty" MinimumValue="1" MaximumValue="100" SetFocusOnError="true" Type="Integer"></asp:RangeValidator>
                                </ItemTemplate>
                            </asp:TemplateField>

谢谢！

您需要在范围验证器上添加Control To Compare

<asp:RangeValidator ID="RangeValidator1" runat="server" 
ControlToValidate="txtDeliveredQty" 
ControlToCompare="OrderedQty" Operator="LessThan" Type="Integer" 
ErrorMessage="The first number should be smaller than the second number!"  
Type="Integer"></asp:RangeValidator>

如何在gridbox中使用comparevalidator和gridview中的boundfield项
