在下拉列表的选定索引更改日历扩展程序不起作用 [英] On selected index change of a drop down list calendar extender is not working

问题描述

on selected index change of a drop down list calendar extender is not working

string strChangeValue = ddlAddchanges.SelectedItem.Text.ToString();

       if (strChangeValue == "Yes")
       {
           txtChangerequiremnetDetails.Enabled = true;
           txtTargetdateforchanges.Enabled = true;
           txtStartdateforchanges.Enabled = true;
           txtEnddateforchanges.Enabled = true;
           txtAgeforchanges.Enabled = true;


       }

日历扩展程序无法使用启用的文本盒子。

我在html页面中也使用过Update面板



我尝试了什么：

the calendar extender is not working on the enabled text boxes.
I have used Update panel in the html page as well

What I have tried:

if (strChangeValue == "Yes")
        {
            txtChangerequiremnetDetails.Enabled = true;
            txtTargetdateforchanges.Enabled = true;
            txtStartdateforchanges.Enabled = true;
            txtEnddateforchanges.Enabled = true;
            txtAgeforchanges.Enabled = true;

            
        }

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="Server">
    <asp:ToolkitScriptManager runat="Server" EnableScriptGlobalization="true" EnableScriptLocalization="true"
        ID="scr1" ScriptMode="Debug" CombineScripts="false" />
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <asp:Panel ID="panelEdit" runat="server" Visible="true">

推荐答案

你应该在UpdatePanel中使用TRIGGERS

You should use TRIGGERS in UpdatePanel

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                                                                    <ContentTemplate>
                 <!--Content-->                                                                                                                                                          </ContentTemplate>
                                                                                    <Triggers>                                                                                        
        <asp:PostBackTrigger ControlID="btnSubmit" />                                                                                    </Triggers>
                                                                                </asp:UpdatePanel>

在触发部分，使用按钮的ID或任何控件内容发布。

In trigger section, Use the ID of the button or any control that makes the content post.
