为什么服务器端变量未绑定到.aspx文本框? [英] Why the server side variable is not getting bound to the .aspx textbox?

问题描述

    Public Class frmFMECA
    Inherits System.Web.UI.Page

    Public LastFailureDate As String

并在.aspx中像这样使用它

and using it like this in .aspx

 <asp:TextBox ID="txtLastFailureDate_GR" Text="<%= this.LastFailureDate %>" runat="server"></asp:TextBox>

，但是在文本框中，除了<％= this.LastFailureDate％>之外，它什么都没有显示.

but it doesn't show that anything but <%= this.LastFailureDate %> inside the textbox.

推荐答案

您需要使用数据绑定表达式.

You need to use a DataBinding Expression.

Text='<%# this.LastFailureDate %>'

如果TextBox不在GridView，Repeater等内部，则需要在 Page_Load

And if the TextBox is not inside a GridView, Repeater etc you need to manually call DataBind() in the Page_Load

protected void Page_Load(object sender, EventArgs e)
{
    DataBind();
}
