You can place a content place holder and add controls into that depending on user choice. But you won't be able to make this very generic solution. You should have an idea on the type of controls what user will add

Take Place Holder in page
Create object of control like as
-- TextBox txt1=new TextBox();<br />
---txt1.ID="txt1";
Add this control in placeHolder
<br />
-- PlaceHolder1.Controls.Add(txt1);
To use this control
use findcontrol method
--
string val=((TextBox)this.Page.FindControl("txt1")).Text;<br />
Best Regard

Hi,
I have used Class library using C# ASP.NET2005 and created a public-private key using Sn -k myfile.snk syntax.
I have signed in the key to the class library created and had builded it.
I have added the dll to the GAC using gacutil /i myclasslib.dll
The dll is successfully added to cache.
Now,
1.How to include the shared myclasslib.dll to my new asp.net c# application?
2.Does the myfile(strongname) created can be used for sharing more than one dlls?
3.If so then how can the stron name can uniquely identify the assembly?
4.Does the c# dll can be used in vb.net windows application?
Thanks,
zari

If your assembly is added to Global Assembly Cache, then you can add reference to it.

Yes you can use that. It will be in MSIL ( Microsoft Intermediate Language ) format. It doesn't care about C# or VB.NET.

The keys of a HashTable are stored as object, so you need to cast the keys to the actual type that you are using for key, before you can make a useful comparison between them.
If you are using framework 2, you should be using a Dictionary instead of a HashTable. Then the keys are not stored as object, so you don't have to cast them to use them.

First method
if ( Session["UserId"] == null )
Response.Redirect("Login.aspx");
Second Method
try
{
string UserId = Session["UserId"].ToString();
}
catch(Exception Ex)
{
Response.Redirect("Login.aspx");
}

Hi Navaneeth
but i have to define somewhere session("userid") somewhere
before writing it on every page. i.e i have to define
on session start event session("userid") or just i have to
write the code on my page.

Obviously, he's assuming you've stored a userId in the session when the user logged in. That is really the most obvious way to keep track of login, and your site obviously supports logging in.

If you didn't want to do it on each and every page, you can create a base page which all of your web pages inherit from and just do it in the base page. That is what I have done.

I tried it its working.One more query i have
define 10 values in different session and when session get expired
then values in my all session gets null or some session values still
remain in session.Because i am sending user to login page i force
user to enter only its password because i am taking its email id on
first page and putting it in session and then checking its password
using its mail id.If values in session (email) is get expired or not?
Rahul

When session ends all your session values will be cleared. If you don't want user to reenter email id, you need to store it in some cookies

Ok Thanks for your help.
