PostBack()之后如何保留只读文本框的文本?

How to keep the Text of a Read only TextBox after PostBack()?(PostBack()之后如何保留只读文本框的文本?)

问题描述

我有一个 ASP.NET TextBox，我希望它是 ReadOnly.(用户使用另一个控件对其进行修改)

I have an ASP.NET TextBox and I want it to be ReadOnly. (The user modify it using another control)

但是当有 PostBack() 时，文本会被重置为空字符串.

But when there is a PostBack(), The text get reset to an empty string.

我了解，如果您将 ReadOnly 属性设置为 TextBox 的 True，则其内容不会通过 PostBack().

I understand that if you set the ReadOnly property to True of a TextBox it's content does not get saved through PostBack().

有没有办法在 PostBack() 之后保留内容并使 TextBox 用户不可编辑?

Is there a way to keep the content after PostBack() and make the TextBox not editable by the user?

我尝试将Enabled属性设置为False，但是PostBack()之后内容仍然没有保存.

I tried to set the Enabled property to False,But still the content doesn't save after PostBack().

推荐答案

我找到的另一个更简单的解决方案:

Another solution I found and easier one:

将此添加到页面加载方法中:

Add this to the Page Load method:

protected void Page_Load(object sender, EventArgs e)
{
     TextBox1.Attributes.Add("readonly", "readonly");
}
