But it's not working.how can I set the display of the div to none through code behind, in aspx I have a div:

<div id="login_div" runat="server">

Answer 1

I believe this should work:

login_div.Attributes.Add("style","display:none");

Answer 2

Style is a collection of name-value pairs so you would set it as:

login_div.Style["display"] = "none";

(Square brackets, not curved).

Answer 3

Since this is a login div, shouldn't the default be to NOT display it. I am going to go ahead and assume then you want to display it then via javascript.

<div id="login" style="display:none;">Content</div>

Then using jQuery:

<script type="javascript">$('#login').show();</script>

Another method you might consider is something like this:

<div id="login" style="display:<%=SetDisplay() %>">Content</div>

And the SetDisplay() method output "none" or "block"

Answer 4

if(displayit){
  login_div.Style("display")="inline"; //the default display mode
}else{
  login_div.Style("display")="none";
}

Adding this code into Page_Load should work. (if doing it at Page_Init you'll have to contend with viewstate changing what you put in it)

Answer 5

try this

<div id="login_div" runat="server">

and on the code behind.

login_div.Style.Add("display", "none");
