在背后的代码中找不到UserControl [英] Not able to find UserControl in Code Behind

问题描述

我在aspx页面上有一个日期选择器"用户控件，但在文件后面的代码中找不到.

I have a Date picker user control on my aspx page which I am not able to find in my code behind file.

objMed.StartDate = Convert.ToDateTime(txtStartDate.CalendarDate.ToString());

当设计显示控件时，尝试构建程序时出现以下错误

名称"txtStartDate"在当前上下文中不存在

While the design shows the control, I am getting the following error when I try to build the program

the name ''txtStartDate'' does not exist in the current context

推荐答案

您可以尝试使用此关键字吗?

Could you try with this keyword

objMed.StartDate = Convert.ToDateTime(this.txtStartDate.CalendarDate.ToString());

您是否添加了页面指令?

have you add page directive?

<%@ Register Src="../UserControl/Calender.ascx" TagName="Calender" TagPrefix="uc1" %>

并作为您页面上您想要的标签.

and as a tag on ur page where ever you want.

<uc1:Calender ID="txtCalender"  runat="server" />

在.cs页面上，使用ID进行调用.
如果有帮助，请不要忘记将其标记为答案. :)
