May be.

But at least he can post the link instead of copying it here. I feel this is not sharing, simply learning how to copy content. You can see in his post one figure name has referred. If CP allows image uploading, he would have copied that too. So it is copied without reading fully.

Hello,

first note that this code concerns .net framework 1.1.

I'm having trouble with the following: I have a class derived from Page. In
the Page_Load of this class I'd like to do the following:

HtmlForm form = new HtmlForm();
form.Name = "test";
form.ID = form.Name;
form.Controls.Add(_header); //    user controls I've instanciated and loaded 
using LoadControl(...)
form.Controls.Add(_menu);
...

// add child controls from the derived page
for(int i = 0; i < Page.Controls.Count; i++)
{
 form.Controls.Add(Page.Controls[i]);
}

form.Controls.Add(_footer);

Page.Controls.Clear();
Page.Controls.Add(form);

What I'd like to achive is to have a base page with a couple of controls on,
from which i can derive further.

The problem I'm having is, that on each round in the for loop, when I "read"
the Page.Control at the given index, the Page.Controls.Count decreases by
one.

Could somebody please shed some light. Thanks in advance!

Greetings from Berlin,

Matthias

Hearing such a problem first time. Try assigning the page count to a variable before starting the loop. ?

Seeing your base class design, I got confused. Why you need add the header like this ? if you know header should be there in all pages, why don't you add this in the design time itself ?

[edit]
One more point, I don't think ASP.NET can maintain viewstate for the dynamic controls added on page_load, because viewstate would be already loaded before page_load fires.

How you are giving file name Confused | :confused:

? ASP.NET will be having delete permissions only in the website, Not in all hard disk locations. When referring a path in ASP.NET always use Server.MapPath() to get files physical location on the server.

Well, can you post that deletion code here ?

Yes. Sure.

System.IO.FileInfo objFileInfo = new System.IO.FileInfo(Server.MapPath("../File/") + Filename.ToString());
System.Security.Permissions.FileIOPermission fp = new System.Security.Permissions.FileIOPermission(System.Security.Permissions.FileIOPermissionAccess.AllAccess, objFileInfo.Directory.FullName);
objFileInfo.Delete();

Have you printed out put of this line ? Are you getting a valid file path ?

-- Abhi -- wrote:

objFileInfo.Delete();

Why all these ? Simply call File.Delete(Path)

Yes...

This path works best in my Local project in my machine.

But after uploading this project DLL to the server by FTP...

Then I got error.

I have used below code :

System.Security.Permissions.FileIOPermission fp = new System.Security.Permissions.FileIOPermission(System.Security.Permissions.FileIOPermissionAccess.AllAccess, objFileInfo.Directory.FullName);

But, I cant find solution with above permission code, this code is meaning less.

Abhi

If you r writing this code in asp.net, so due to security reason this will not done, u have to use impersonation or check authentication mode.

First one is Ok.

Second One is not valid

The second one can be used only in context databinding expression ( <%# .. >), but that's it. It's ASP.NET sugar, nothing else. Under the hood, ASP.NET will generate exactly the same code. See this excellent blog post[^] for more details.
