我的gridview中有文本框列。我想在某些情况下禁用我的文本框，例如当在文本框中输入的值为2000时，其他行上的“2000/500=4”文本框将被禁用，它应该是特定值的倍数

                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>

                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

我不知道应该在

gridview

中触发哪个事件，或者使用

javascript

来处理

textboxchange事件
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>

                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

这是我的网格视图代码.aspx
                     <asp:TemplateField HeaderText="Installment No.">

                </Columns>
                </asp:GridView>



如果用户在文本amount中输入的金额大于500，则我希望禁用gridview行的下3个文本框。
这包括两部分
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>

                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

第1部分运行时
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

您应该查看RowDataBound
事件：
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

所以GridView的声明是
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

<asp:GridView id="grd" runat="server" OnRowDataBound="grd_RowDataBound">

第2部分客户端
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

然后，我希望在客户端输入文本时使用jQuery禁用文本框：
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

首先，向文本框添加一个类：
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

<asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px" CssClass="watchedAmt"></asp:TextBox>

jQuery中的目标可能有点偏离，因为您需要根据网格布局进行定位，但它应该可以让您接近目标
                     <asp:TemplateField HeaderText="Installment No.">
                        <ItemTemplate>
                            <asp:Label ID="LblInstl" runat="server" Text='<%#Eval("InstallmentNo") %>' Font-Bold="True"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Due Date">
                        <ItemTemplate>
                            <asp:Label ID="LbldueDate" runat="server" Text='<%#Eval("DueDate") %>' Font-Bold="True" ></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Deposit Date">
                        <ItemTemplate>
                            <asp:TextBox runat="server" Text='<%#Eval("Datedeposit") %>'  Enabled='<%# (string) Eval("Datedeposit") == "" %>'  ID="TxtdepositDate" Width="200px"></asp:TextBox>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Amount">
                        <ItemTemplate>
                            <asp:TextBox ID="TxtAmount" runat="server" Text='<%#Eval("Amount") %>' Enabled='<%# (string) Eval("Amount") == "" %>' Width="200px"></asp:TextBox>
                            <asp:HiddenField runat="server" ID="Hdn" Value='<%#Eval("InstallmentAmount") %>'/>
                        </ItemTemplate>
                    </asp:TemplateField>


                </Columns>
                </asp:GridView>

试一试。你能给我看一些代码吗？我只写了我的gridview数据绑定代码。很难理解你问题的内容。也许发布一些图片/屏幕截图来描述你想要实现的目标。我有一个文本框栏和一个日期栏。当用户在文本框中输入值时，我必须基于禁用其他gridview文本框列。您必须发布标记以使其更简单。。。你希望这种情况发生在客户端吗？因此，不是网格中数据的条件，而是用户的输入？根据gridview中文本框上的用户输入，我想禁用其他gridview行。好的，您将不得不发布您的标记，以供任何人帮助。我想这需要是客户端。

                        <ItemTemplate>
