OK, I looked that up and it seems like it would work instead of the cookies. My question is, however, is there an event that I could handle so I could set the Session[] variable as I was navigating out of the page?
|
|
|
|
|
No, but you can set the session variable everytime a menu item is selected so it's always the most recent selection, then on Page_Load load the variable.
Asp.net is all server side and there is no message sent to the server when a page closes or the user leaves it, so you can't take action. Probably your biggest adjust from windows forms to asp.net is going to be the separation between client and server.
|
|
|
|
|
I've been noticing that. Is it possible to set the session variables from the .js scripts that do the filtering (there's a button)?
|
|
|
|
|
No, the session variables never leave the server. If you want to set a session variable from the client, you have to send the information to the server and do the change on the server.

Hi,
For the SmtpClient object there is a property called SmtpServer, there you have to provide the IP address of the smtp server, in the yahoo mail box case you can try with URL.

I would like to introduce myself as ASP.Net 2.0 beginner. I face a problem when using gridview and sqldatasource.
Problem:
Initially I tried using the SQLDatasource control and Gridview with one parameter in the select query. I made that parameter as a control parameter and set the autopostback of the control. Everything worked fine.
Now I want to have multiple control parameters set for one SQLDatasource and GridView combination (It is basically a kind of search screen and the procedure for select command has so many parameters). I have created all the properties for these controls. But getting stuck with how to trigger the retrieval process. If it is one control, I used the autopostback and ASP.Net did the rest. Now that I have to manually trigger the retrieval of data and the binding on a search button click, am getting stuck.
This is an urgent requirement and Could you please help???
Thanks
Geetha

all you have to is put datagrid.databind(); in the code that handles the event for your search button.

Is it secure to place connection string in our assembly ? for example store it in a variable in our business class .or its better to place it in web.config file.
tell me why ?
|
|
|
|
|
Normally it is good to put the connection string in web.config file.
Best Regards,
Apurva Kaushal

Not normally. There are valid and useful reasons for not storing it in the config file.
only two letters away from being an asset
|
|
|
|
|
The web.config file is plain text. An assembly is compiled. Which would be easier to read?
You can encrypt the config file. You can also use a tool, such as ILdasm, to view the inards of an assembly, but this is a little more difficult than simply opening a plain text xml file.

Hi,
The connection string should be only on the web.config file.
use CipherData class so that we can encrypt it. then it will be very much secure.
Happy Coding

Ofcurse its better to save in web.config. because if you deside to change it , you have not to recompile your app and upload dll file...!
|
|
|
|
|
Storing it in your business layer should be the last resort, as will require recompiling and redeploying every time you need to change it.
Other options are:
- store in web.config as clear text
- store in web.config as encrypted string (ASP.NET v2 feature)
- store encrypted in registry (current server) with registry keyname stored in web.config
It all depends on how secure you want it to be (who else has access to your web.config file?) and your deployment process (manual/automated).
.leON.
