如何保持后回后，只读文本框的文本？ [英] how to keep the text of a Read only textbox after post-back?

问题描述

我有一个ASP.NET文本框，我希望它是只读。 （使用另一个控制用户修改）

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

但是，当有一个回发，文本被重置为空字符串。

But when there is a postback, the text get reset to an empty string.

我明白，如果你设置的只读属性的 true的文本框的内容不打通后救回。

I understand that if you set the readonly property to true of a text box its content does not get saved through post back.

有没有办法让回传后的内容，使文本不能由用户编辑的？

is there a way to keep the content after postback and make the textbox not editable by the user?

我试着在已启用属性设置为假，但仍内容不回发后保存

I tried to set the Enabled property to false, but still the content doesn't save after postback

推荐答案

另外soloution我发现，更容易之一：

Another soloution I found and easier one:

这添加到页面加载方法

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