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...

Then why don't you tell this before.. This can be done using a simple javascript. Goto view source of this page and check

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.

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.
Do i need to import any namespace in my class file to access this application variable in my class??
thanks,

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,
Senthilraj K

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
Cheers,

Many people spend their life going to sleep when they’re not sleepy and waking up while they still are.

But using web.config for only a connectionstring isn't really the neat way, because handling a web.config is relatively pretty time consuming...

Do you mean using AJAX in ASP.NET, or using the ASP.NET AJAX framework ? How many images are there, that you need to make an AJAX call ?

Because you failed to provide a value for one or more parameters ? This is the ASP.NET forum, classic ASP belongs in the web dev forum.

That will help u.
