ASP.NET

you can't. Not with ASP.NET. You'd have to write a java applet, or a C++ OCX ( which would only work in IE ), to do that. ASP.NET would at that point have nothing to do with it.

With code.

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;

if(UserHasPermission)
{
Control ctr=this.Master.Findcontrol("ControlID") as Control;
ctr.Enabeled=True;

}

Problem after deploying ASP.Net application

5-Oct-09 19:20

With ASP.NET, you can't. With a Java applet, you might be able to, or a C++ OCX, if you want to write a site that only works in IE.

Hello All,

I am facing very strange problem.
I deployed my ASP.Net application on a machine, i set up IIS, installed .Net framework, created virtual directory, set permissions.
But when i run my application in web browser, it showed me code of aspx page instead of design.
I am really confused why i am facing this problem? Confused | :confused:

Am i missing something or my aspx pages not inheriting c# code files?
Please guide me?

Thanks,
Nagendra.

It means that ASP.NET is not set up on your server. Run regsvr_iis ( from memory ) from the .NET folder, if you have .NET installed, so that IIS can see it.

so, is it necessary to install whole .Net on that machine? can't i do with only .Net Framework.

I couldn't find regsvr_iis on my local machine, i have .Net on my local machine. D'Oh! | :doh:

Dear Nag,
You need to reinstall the .net framework here.Generally this error occurs when You install .net framework and then IIS.Install only .net framework and check it out.
if it still shows let me know.
