Setting textbox read only property true using javascript

Question

how to set textbox readonly property true or false using javascript....in asp.net

Answer 1

you can try

document.getElementById("textboxid").readOnly = true;

Answer 2

Using asp.net, I believe you can do it this way :

myTextBox.Attributes.Add("readonly","readonly")

Answer 3

document.getElementById('textbox-id').readOnly=true should work

Answer 4

I like jquery for things like this, see example. Depending on how your asp.net application is written, you may need to register your javascript to get this to work properly.

Answer 5

it depends on how you trigger the event. the key you are looking is textbox.clientid.

x.aspx code

<script type="text/javascript">

   function disable_textbox(tid) {
        var mytextbox = document.getElementById(tid);
         mytextbox.disabled=false
   }
</script>

code behind x.aspx.cs

    string frameScript = "<script language='javascript'>" + "disable_textbox(" + tx.ClientID  ");</script>";
    Page.ClientScript.RegisterStartupScript(Page.GetType(), "FrameScript", frameScript);
