Re: Error Use of unassigned local variable 'ClientScript'

Rather than using RegisterClientScriptBlock, it is better to use RegisterStarupScript

use

if(!this.ClientScript.IsClientScriptBlockRegistered("myscript"))
this.ClientScript.RegisterStartupScript(this.GetType(), "myscript", strScript , true);

Hope this helps. Rose | [Rose]

Make sure one things : if you have AJAX Script Manager in your page, then you have to use ScriptManager rather than ClientScript. Smile | :)

Yes... RegisterStartupScript places the script after all the objects are rendered while RegisterClientScriptBlock places the JS at the beginning.

Thus say you are calling a javascript using RegisterClientScriptBlock which gets an element, you will find this null, as the script gets executed just before any html is rendered. In case of RegisterStartupScript the script is placed after the html is generated. So If you want to place a javascript call in your html, always use RegisterStartupScript.

Hope you got it. If not I can give you examples. Smile | :)

Can you atleast wrap the code. It is not readable.

Secondly, do you think anybody is gonna read all code of yours. Please narrow it down.

authentication C# ASPX

Dear All,
I have read a lot of articels and infos about the authentication but i found no hint where my problem was descripted.

My problem is, I have a intranet application and my authentication is "Windows".
It works perfect but how can I handle if on a windows client another user as the windows user was logged into my web application?

That mean i need a logout for the actual webapplication and a relogin with another user (DomainUser).

Is this possible?
Did I need a mix from Windows - authentication and Form authentication?

Thanks for your Help

Windows Authentication means, Authenticating the User from Active Diretory.

If you set authentication mode as windows, A popup will ask for user name and password for the user. Which should be the DomainName\UserName and Password.

User who is not under that domain in which your application is hostes will not able to access the site.

Hello,
if i connect from a client which was not inside my domain a popup in the IE ask for user and passwort. That's right because i have customized my IIS to "Windows Integrated security".
If the client was in my Active Directory no popup occur. That's also ok.

But, and that is my main question how can i handle if the client is already connected with a windows user which is in the active directory for example "GASTUSER" and now another user will login with his own user "USERXXX" and his one security settings but without relogin on the client pc. Only Logout for the intranet application and Login with user "USERXX".

I tried this with Form Authentification and a connection to my LDAP but it's not really fast and we have a lot of directory with different users.
Maybe the solution is very easy but i have no idea.

Bye

You can mix them. Use the standard ASP.NET login controls and handle the authentication request on your own. You can use AD to authenticate or some other credential system.

only two letters away from being an asset

Hello Mark,
if i understood correct.

1. The IIS is configured with "Integration Windows authentication"

2. I have created a standard ASP.NET login control.
In the web.config the setting authentication = "Forms" and i have a Login and a Default URL defined.
I added a new Provider: System.Web.Security.ActiveDirectoryMembershipProvider with the connection string to my Active Directory.

In the default.aspx i check if the User.Identity.IsAuthenticated if yes a lot of settings was set.
So now have the user the possibility to logout. If the user click to logout i to the following
"FormsAuthentication.SignOut() and Response.Redirect("tomylogin.aspx")"

In the "tomylogin.aspx" the stanard ASP.NET login control exists. If the user inserting User and Passwort and click on logon the figures was checked because of the settings in the web.config (Active Directory String....). Is the user authenticatet a redirect to my default.aspx was execute.

My problem now is

1. the first check with the Active Directory is very very slow (i think we have to much users and structurs in the ADS).
2. Is this the correct way for a logout and login to my intranetpage?
3. Can i handle this easier?

Thanks for your help.
best regards
gitschi
