How to keep the Text of a Read only TextBox after PostBack()?

Question

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

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

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

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

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

Answer 1

Another solution I found and easier one:

Add this to the Page Load method:

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

Answer 2

Have your other control store the value in a hidden field, and on postback, pull the value from the hidden field and push it into the textbox on the server side.
