Hi,
I have a form which contains a gridview which I populate in the Page_Load method from a basic datasource (an ArrayList of objects). I want to be able to add items to the gridview from a button and I also need to be able to delete and ideally edit the new entries.
I've read about the GridView and it seems there are no simple ways of adding my items. Is there a way of reading the information from the GridView back into an arraylist, adding the new item to the arraylist and re-binding the gridview to the modified data source?
How about the deleting and editing items?

Have you looked at either the LinkButton or HyperLink controls?
|
|
|
|
|
yeah,
i have seen LinkButton & Hyperlink, they are undrelined, i want the control which is not underlined.
once visit: www.microsoft.com
in this,some controls r there without underline
|
|
|
|
|
Have you thought about changing the style of the object so that it isn't underlined? That's how the other controls work.

You can write an event for Label_click by just double clicking the Label in the Visual Studio 2005 or whatever IDE you use. This creates an event handler for the specified Label click.
You don't have to be AFRAID!

All i know is that you need to do forms authentication to be able to talk to active directory, or am i wrong?
Unfortunaltely, i have never used this concept before and i am clueless about it. If you can redirect me to some usefull sites that covers the topic.
Thanks in advance.

Hi all!
I just converted a .net 1.1 web project to .net 2.0 and now I'm getting a strange problem:
I have a custom class implementing IPrincipal to store the user identity in Context.User, sample code below. After storing the Principal i redirect from the login-page. When I retrieve the Context.User on the next page it is of type GenericPrincipal????? The user information is still there but of course not with my custom methods. I guess I could rewrite the code to use GenericPrinfipal instead, but why does this happen??? It did not happen before the conversion (and as far as I can think of I didn't make any other changes to the code).
I use Forms-authentication (using Windows authentication gives me the WindowsPrincipal when retrieving Context.User - i.e. the useridentity of the useraccount running the app, not of the user logged in to the web app).
I feel there has to be a logical explanation for this and I am grateful for any help!
Thanks!
/*******************************/
CustPrincipal newUser = CustPrincipal.ValidateLogin(TxtUsername.Text, TxtPassword.Text);
// Create the authentication ticket
FormsAuthenticationTicket authTicket = newUser.GetAuthenticationTicket();
// Now encrypt the ticket.
string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
// Create a cookie and add the encrypted ticket to the
// cookie as data.
HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName,
encryptedTicket);
// Add the cookie to the outgoing cookies collection.
Response.Cookies.Add(authCookie);
// Add user to context
Context.User = newUser;
System.Threading.Thread.CurrentPrincipal = newUser;
/********************************/

Overridding Principal in:
protected void Application_PostAuthenticateRequest(object sender, EventArgs e)
Instead of
protected void Application_AuthenticateRequest(object sender, EventArgs e)
In Global.asax.cs worked for me in an ASP web application

Why are you using the stored procedure there with ds.tables there you need to specify the table name or index of the table.
Best Regards,

Exactly!
You are placing a stored procedure in the place of an Index.
If you want to call a stored procedure, there are other neat ways of doing it.
Like using a stored procedure in a SQLDATASOURCE.
You don't have to be AFRAID!

I think, you don't have the permission to save the file to the specified location ("C:\temp\"). Set write permission to IUSR_YOURMACHINENAME user to that folder.
If you still have the same problem, post the complete StackTrace information. The Error Message you posted is not sufficient to debug the Error.
