C# - Trying To Access Telerik RadEditor Controls In Master Page's Code Behind As Follows... Giving Error

foreach (Control control in ContentPlaceHolder1.Controls)
{
if(typeof(Control).Equals(Telerik.Web.UI.RadEditor))
{
label1.Visible = true; label1.Text = "dhchk";
// control.CssFiles.Add("~/styles/myStyle.css");
}
}

Error;-

'Telerik.Web.UI.RadEditor' is a 'type', which is not valid in the given context

Also, is this the correct way to add CSS class to radEditor controls ??

control.CssFiles.Add("~/styles/myStyle.css");

I actually wanna add 3-4 customized classes..how to do that?

also I was wondering if I can add some javascript or something in my Master page that will detect the ALL the radEditor controls and set their css classes ? don't know much of Javascript..how can that be made possible? how do I go about that? but first I want css classes to be set in code behind..what's wrong with the code?

[EDIT]

@Geek..I tried calling like this..is it correct?

Control c = new Control();
DoSomething(c);

now its giving this error in the method:-

The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)

[EDIT]

I do have this namespace added "using System.Web.UI.WebControls;" why this error ??
