Yes you can. THe Master property, returns a MasterPage. What you need, is to upcast that to an instance of your master page class. Although, I think you should be able to handle all this permissions stuff inside the master page class itself, what I do if I ever use master page, is create a new base class for all my pages, which has a strongly typed MasterPage property that returns the upcast Master page. Then I can access the methods however I want. Of course, not being a hack programmer, I never make the controls on the master page public, I use methods and properties to allow only the required access.

Permission Means, just to check whether the user is enabled for a particular feature... So that the particular button is enabled for him... for this, I'll get the information abt the user whether the user is enabled or not from the database table. Then , I hav to set that particular button to enabled or disable. When I'm tried to get the control of Master Page, I can't do this in code behind... Is any other way to achiive this??

I guess you need to read my answer again, I explained exactly how to do it. And, as I said, the session should store details of who is logged in, so why can't your master page check for itself what it should show as a result ?

if You are Using forms authentication
//I did it for Image Button replace it for required menuitem
if (Page.User.Identity.IsAuthenticated)
{
//logout
((Image)Master.FindControl("ImageButtonLogin")).Visible = false;//login ImageButton
((Image)Master.FindControl("ImageButtonLogout")).Visible = true;//logout ImageButton}If this is not you are looking for sorry..!

Yes, this sort of thing will work, but it's ugly. Creating a strongly typed property is a far nicer solution IMO.

Ofcourse you can. I think you didn't understand what CG told you to do. Thats the best option, but if still you need code then try this:
HtmlForm frm = (HtmlForm)Page.Master.FindControl("form_id");
Menu mnu = (Menu)frm.FindControl("menu_id");
mnu.Enabled = false; -

you can use like this... if(UserHasPermission) { Control ctr=this.Master.Findcontrol("ControlID") as Control; ctr.Enabeled=True; }

MenuItem mnu = (MenuItem)frm.FindControl("menuitem1"); This shows error..... I used this code now.. Menu1.Items[3].Enabled = true; It's working for me......... Thank you for ur idea...
Its good that you worked it out but this is not a good way to achieve it. It you can, try to implement the way told above. :)
