如何在PostBack()之后保留只读文本框的文本? [英] How to keep the Text of a Read only TextBox after PostBack()?

问题描述

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

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

但是当出现PostBack()时，文本将重置为空字符串.

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

我了解到，如果将ReadOnly的ReadOnly属性设置为True，则其内容不会通过PostBack()保存.

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

是否有一种方法可以保留PostBack()之后的内容，并使用户无法编辑TextBox?

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

我试图将Enabled属性设置为False，但是在PostBack()之后仍然没有保存内容.

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

推荐答案

我找到了另一种更简单的解决方案:

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");
}
