If your code is posting back then in the C# you can set ReadOnly = false. If you want to do it on client side I would recommend using jQuery and then you can do

JavaScript

$("#idOfTextBox").attr("disabled",false);

+5. I Wasn't thinking of web for some reason.

Ha. Good point. I went back and looked and it was not tagged ASP.Net. It is so trivial in WinForms I assumed it must be the web.

Solution 1

1) Add a click handler to your code behind and tie it to your Button control.
2) In the click handler, write something like YourTextBox.readonly = false
3) That's it.

Cheers.

Edit: After seeing your answer that this is a web app, See ryan's answer as the way to go.

VB

'//Or if you wanna switch between enable/disable,you can use CheckBox
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    TextBox1.Enabled = False
    TextBox1.BackColor = Color.Red
End Sub

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
    If CheckBox1.Checked = True Then
        TextBox1.Enabled = True
        TextBox1.BackColor = Color.Green
    Else
        TextBox1.Enabled = False
        TextBox1.BackColor = Color.Red
    End If

End Sub
