You can't reload only specific control when you click button. You can reload it's value using AJAX

Reloading value ?

you need to install Microsoft AJAX development kit and search for some tutorials on how to program with them. Or you can do this by writing XMLHttpRequest using javascript.

However, you can also reload the entire page by :

Response.Redirect("yourpage.aspx");

however doing this makes all controls lose their values...

Hi Everybody,

So I'm using LoginView on my web application and I have little problem with Permissions and Groups. I have only 2 Groups and want to load different menus (Standard Menu Control) for different roles, but because i have LoginView on almost whole master page I cant do this using <rolegroups> and <asp:rolegroup roles="Administrator"> tags.

Is There any othet solution? Please Help to solve this problem.

Thnaks,
Toto

hi all,

I have created an Application level connection string variable in my Global.asax

Like:
Application("glbConnection") = con.getDBConnection()

I accessed that variable in My Business class like,

con As IDbConnection = Application("glbConnection")

But i Got the Error as ,

System.NullReferenceException
{"Object reference not set to an instance of an object."}

Message : "Object reference not set to an instance of an object."

I need to access my application variable in my Class file.
can anyone help me out to solve this problem

Thanks in advance.

Regards

Try Context.Application

To solve your current problem : I guess con.getDBConnection() returns a null value

To solve your next problem, I don't think you want to connect to your database throughout your website this way.

You say you have a business class. The business class should be in a separate project (your business project) which contains all db functionality and stuff and returns the required information to your user interface (in this case a website). In theory, you're website shouldn't be able to 'know' your connection string.

i am getting the connection string in my code behind file when i use the appliaction variable (webform1.aspx.vb)

When i try this with my class i am getting the error.

hi navaneeth,

i tried with your option.but, when i try to type the Context.Application i am getting the error as 'Context' is not accessible.

I have imported the 'System.Web.HttpContext' in my class.but still getting the error....

do you have any sample code to do this????

thanks,

Erhm, in this case, you can better create a function which connects to the database for you in your businessfile

public void ConnectDb(object ConnectionString)<br />
{<br />
if (ConnectionString == null)<br />
return;<br />
<br />
con = new con(ConnectionString.ToString());<br />
<br />
}<br />

and call that function from your webpage

ConnectDb(Application["yourvariable"]);

For security reasons you should define your connection strings in web.Config, and access then using the ConfigurationManager.ConnectionStrings[^] properties
