I have a div element which I would like to change it'e dir attribute from the code.
The problem is that I can't set the runat=server attribute on the div, so it's not accessible from the code.
Using asp.net, c#, framework 4.0.
Any idea?
Thanks.

3Why do you say that you can't set runat="server"? As I remember WebForms it's possible (you'll get untyped HtmlControl object).oryol– oryol2011-07-16 20:21:42 +00:00Commented Jul 16, 2011 at 20:21

I have a grid unger this div, and I loop on this grid, and changing things on the grid. if this div is set to runat=server, then this loop get messed up. Don't know why..Itay.B– Itay.B2011-07-16 20:24:57 +00:00Commented Jul 16, 2011 at 20:24

@Itay.B: Then I suggest you start a separate question to find out why runat=server on the div messes up your loop on the grid.Heinzi– Heinzi2011-07-16 20:32:46 +00:00Commented Jul 16, 2011 at 20:32

If you don't want to set the div to runat="server" so you can do the following:
<div dir='<%= GetDir() %>'>
Your text
</div>
and in the code behind you can set the direction using the following code:
if(You Condition)
{
return "ltr";
}
else
{
return "rtl";
}

Yes, you can't access to the client elements on the page, only to the server-ones (asp.net is a server-oriented framework). The client controls are compiled to the Literal controls with html in them.
If you don't want to set div for the runat="server" attribute, you can register client script to edit your divs content.
If you set the runat="server" attribute, and set the ID="YOUR_DIV_ID_HERE" for it, it will be accessible from code under YOUR_DIV_ID_HERE name.

If you want you can do this also
<div><%= your server variable %> </div>

Use Jquery and call back function to call server side function.

You can set the runat="server" attribute on a HTML element. Just did a local demo, works just fine. It will be represented as an HtmlGenericControl (http://msdn.microsoft.com/en-us/library/7512d0d0(v=VS.100).aspx).
EDIT: You say you cannot use runat="server" to access the element from code. I am not sure why that would be a problem, as the html rendering should be no different. Maybe it has to do with the elements client side id beeing changed? If you depend on this, you could try setting ClientIdMode=Static for your div.
