if u r using Get method and u r passing some data from one page to another page then data is send through url and anyone can see that data in the address bar.But in case of post method data is divided into small packets and encrpted also and then data is sent .
So Get is not Secure and Post is Secure.
In get u can transfer maximum of 240 characters of data whareas in case of post there is no limitation.
I hope this will help you.

POST is not secure and not encrypted! It is still sent as plain text in the HTTP request and is easily viewable.

Hi Friends,
I have created a module which will load the directories in the given root directory in a TreeView. When we choose an item it will load the Folders and files in the right side pane (Panel). Everything works fine. For loading the Folders and files in the right pane, I am using LinkButton for each item nested inside a Server-side Table control. I added Click event to that LinkButtion to open the clicked item. But this Click event is not firing, but the page is postbacking. This LinkButtons are generated dynamically, where the ID is assigned dynamically.
Can anyone help me with this problem?

Here PnlFoldersFiles is the Right side Pane (Panel)
Additionally I have the Click Event separately. I believe you don't need that event.

Hi,
You should create an handlere to handle event of linkbutton and assign that handler to the click event of dynamically generated linkbuttons at runtime.
Have a look at following.
The following is the handler to handle command event of your link button.
Command event will fire when u click on the linkbutton.
We consider command event because in this event you can differentiate which linkbutton is clicked and depend on commandname and commandargument you can execute accordingly.
protected void lnk_Command ( object sender, CommandEventArgs e )
{
string strCommand = e.CommandName;
string strArgument = e.CommandArgument;
}
In the following code I m creating a linkbutton dynamically, assigning ID, CommandName, CommandArgument and EventHandler to it.
LinkButton Lnk = new LinkButton();
Lnk.ID = "ID";
Lnk.CommandName = "urcommandName";
Lnk.CommandArgument = "urCommandargument";
Lnk.Command +=new CommandEventHandler(lnk_Command);
This way you can create as many linkbuttons and assign unique commandargument and commandname to each of them.
I hope this will help you.
Thanks and Regards,

Did you said,

I am afraid, LinkButton does not have a Property/Method as Command. Its an Event, where we can't assign by direct method.
I have already added the Click Event for that LinkButton using AddHandler method. If you want to know more about the code see that code I posted for the previous reply.

Hi,
I applogize for not seeing your code properly.
Command is not a property/method of linkbutton but its an event and u can use addhandler method for it as u do with the click event.
I suggested the command event not the click event because in command event u can decide what code to execute depend on the commandname and commandargument.
but if u want to use click event then that's fine.
According to my observation of your code it is correct and as u r adding handler for each of the linkbutton it should work fine.
There may be some other problem. Did u tried by debugging or puting some output statement in the event handler?
Thanks and Regards,
Chetan Ranpariya

Its ok.
Chetan Ranpariya wrote: Did u tried by debugging or puting some output statement in the event handler?
Yes. I do have. Additionally I added another table with the same logic to load the files, and added LinkButton with the Click event. There the event is firing. I don't understand why?

hi all,
I have created a web application project in asp.net 2.0 and i have created the .msi installable file using the web deployment method of VS 2005.
I installed the project and tried to run it using the virtual directory name i gave during the installation process.
I got the parser error as
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.210
then I came to know that the .DLL file in not extracted into the bin folder instead its been extracted to the main folder where other aspx files been extracted.
I need to solve this problem.
When we follow the steps in VS 2003 its working good.but in 2005 the .DDL file has been extracted to main folder.I don't know its there any problem in the steps i have executed OR its the default procedure of VS 2005 .
can any one solve this problem
PS:. i need .DLL must be extracted to bin folder.because we ll give that .msi file to our client.it should be in working condition if we execute the .msi file.
thanks in advance

Hi,
i have an asp.net application which has pages in different folders like
supervisors, managers etc.
and each folder has n number of pages(aspx). it is finding difficulty for me to check the user rights for each page. so is it possible to restrict the user if he does not have the manager rights to all the pages in the manager folder?
Please help.

You must have a list of users, roles and UserRoles. You will have to use windows security to load the roles for the current user. Then ;
protected void Page_Load(object sender, EventArgs e)
CheckRole()
{
if(!IsPostBack)
{
//Do Something
}
public void CheckRole()
{
if (!Context.User.IsInRole("Manager"))
{
thow new Exception("Access Denied");
}
}
}
You can usethe windows security using the following:
using System.Security.Principal;
and then
IIdentity identity;
String[] roles = {"manager","employee"};
GenericPrincipal g = new GenericPrincipal(identity, roles);
You will have to fix the IIdentity part above.

Use the web.config file to set security for the folders, similar to below
<configuration>
<location path="Folder1">
<system.web>
<authorization>
<deny roles="group"/>
<allow roles="admin"/>
<allow users="?"/>
</authorization>
</system.web>
</location>
</configuration>

I create a datable in the event of button1
how can I use it in the event of button2? please help me
I do this :
in button1
Session["temptable"]=dt;
in button2
dt=(DataTable)Session["temptable"];
when I debug it
messege show it is not exit dt in event of button2
|

Your question makes no sense. Are you sure the table does not exist ? dt is null, or you get a message that the variable does not exist ? If the latter, then you're in release mode.

Hi all,
I'm a programmer in Web developer with ASP.NET 2.0, C# basic. I have this issue and it cost me lots of time on investigating the solution. Let me explain the scenario in the easiest way to understand. Let say i have site A and site B, both of them have Response.Cache.SetCacheability(NoCache), reason of disable caching is prevent user from hitting back button to go back to their previous viewed pages after they signed out. And i succeed in this prevention. But i've got the issue of Page has expired. When i deal with surfing like go to Page A, then B, then hit back button to Page A, then back button to B again and again, there's nothing happen because they are 2 different pages. but when i work on Page A only, let say i have a multiview menu in Page A, then i switch from tab X to tab Y, then hit back button, that throw Page has expired. Im so sick with this. As far as i know that because the post back url point to the same page, and this is just a warning from IE from duplicating request to one page, but this is disturbing end user a lot. Is there any work around this?
Please assist me on this, any of your solutions are appreciated.
Thank you very much.

I moved this to the ASP.NET forum, please in future respect the notice that says 'do not post programming questions in the lounge'.
