取决于所选的 telerik 组合框项目，当我在 aspx 页面中编写这样的代码时，我想显示标签名称和文本框

<telerik:GridTemplateColumn DataField="DeductionCode"   Visible="false" UniqueName="DeductionCode"  HeaderText="DeductionCode">
                                    <ItemTemplate>
                                        <asp:Label runat="server" Visible="false" ID="lblDeductionCode"   Text='<%# Eval("DeductionCode") %>'></asp:Label>
                                    </ItemTemplate>
                                    <EditItemTemplate>
                                        <telerik:RadTextBox ID="txtDeductionCode" Visible = "false" runat="server" Text='<%# Bind("DeductionCode") %>' MaxLength="2"></telerik:RadTextBox>
                                        <asp:RequiredFieldValidator  ControlToValidate="txtDeductionCode" ID="rfvtxtDeductionCode" Display="Dynamic" runat="server" ></asp:RequiredFieldValidator>
                                        <asp:RegularExpressionValidator id="revtxtDeductionCode" 
                                               ControlToValidate="txtDeductionCode"
                                               ValidationExpression="^[a-zA-Z0-9'`-´\s]{2}$"
                                               Display="Dynamic"
                                               ErrorMessage="Please Enter 2 charecters only"                                                 
                                              runat="server"
                                              SetFocusOnError="True" />

                                    </EditItemTemplate>
                                </telerik:GridTemplateColumn>

当我尝试在 page_load lbldeduction= false 上编写时，标签名称显示错误消息..另一种方式我试图在编译时在 selectedindexed 函数中显示可见 false 和 true，显示错误，如 lbldeductioncode 具有空值，但 texbox 工作正常，如可见 false 和 true ..唯一的问题是我无法执行标签名称可见 false 和之后选定的组合框项目标签名称可见 true..

原文

depends on the selected telerik combox item i would like to display the label name and text box when im writing the code like this in aspx page

<telerik:GridTemplateColumn DataField="DeductionCode"   Visible="false" UniqueName="DeductionCode"  HeaderText="DeductionCode">
                                    <ItemTemplate>
                                        <asp:Label runat="server" Visible="false" ID="lblDeductionCode"   Text='<%# Eval("DeductionCode") %>'></asp:Label>
                                    </ItemTemplate>
                                    <EditItemTemplate>
                                        <telerik:RadTextBox ID="txtDeductionCode" Visible = "false" runat="server" Text='<%# Bind("DeductionCode") %>' MaxLength="2"></telerik:RadTextBox>
                                        <asp:RequiredFieldValidator  ControlToValidate="txtDeductionCode" ID="rfvtxtDeductionCode" Display="Dynamic" runat="server" ></asp:RequiredFieldValidator>
                                        <asp:RegularExpressionValidator id="revtxtDeductionCode" 
                                               ControlToValidate="txtDeductionCode"
                                               ValidationExpression="^[a-zA-Z0-9'`-´\s]{2}$"
                                               Display="Dynamic"
                                               ErrorMessage="Please Enter 2 charecters only"                                                 
                                              runat="server"
                                              SetFocusOnError="True" />

                                    </EditItemTemplate>
                                </telerik:GridTemplateColumn>
