Using databases . When User login into your application , check is there any entry in the database with that user name or not. If not, make an entry and enter into the application. If yes, message that some one has already logged in into the application it the same credentials.

Check it on Login

if(UserIsInApplication(UserID)) { Alert("Already Logged in with the same credentials..." } else { MakeDBEntry(UserID); LoginApplicatin(UserID); }

Note :
You have to implement all those methods, I have given just for your understanding
Remove the DataEntry from database when user log off Application , other wise user never be logged into the application .
Here is another Tricks , What happend , If user close the browser instead of Click on "Logoff"

I had made a javascript function , that will call on the page unload if and only if , the user close the Browser ([X]), Alt+F4 and From Task Manager.
on that function , I have open a popup ( Location will not be visible to user means top=10000, left =200000 like that ) and from there I have callled the server side code to clear database Wink | ;)

.
What about yours ?

Dear All,

I have a user control inside a page which is used to login.

Also the page has a search option.

When the "Login" option is clicked the login window will be opened using the popup control extender (AJAX Control).

When the popup is opened then the default button for the page should be the "Submit" button in the login window which is in the user control.

If the Login window is not opened then the "Search" button has to act as the default button and while clicking on enter key it has to call the search function.

I have coded as the following to set the "Submit" button as the default button in the user control on page load of the user control.

Page.Form.DefaultButton = this.FindControl("imgbtnSubmit").UniqueID;

Can any one tell me how to get rid of this issue?

Thanks a lot in advance.

Best Regards,
M. J. Jaya Chitra

User should select Theme from any control. Means they can select by clicking a link , or from dropdown. Now if they selecting from dropdown , then you should no the value that what user selecting , based on that you can change the theme.

No... You are running on Wrong Direction !! You do not need to pickup the color. I believe for every theme name , you are having the Theme, and You are Changing the Theme. I am just giving you one suggestion , that Try to use HttpHandler , which will apply the theme to all of your pages, including popup at runtime. Do not need to pick the color and applying it.

cheers,
Abhijit

Can you tell where to find information to use HttpHandler to apply the theme to all of pages including popup.

Abhijit Jana2-Jan-09 20:59

2-Jan-09 20:59

Here It is[^]
Use session to store Theme Name, and Apply Change using HttpHandler .
Check This Two methods

context.Session.Add()<br />
context.Response.Redirect()

Now, Its on you to implement it. If I give you complete code, that does not help you to learn .

You want to mean that when you select some value from dropdown list, based on that you want filed should be visible true or false. if yes,'
As you said, you have placed Dropdown list inside updatepanel , Did you place Those filed inside the updatepanel or not ? if no , then place then also . Because, when you change the content of Dropdownlist, then only it postback, not the other control of that page. Or even you can use multiple updatepanel and you need to change the updatemode="Conditional" and Explicitly update them when required.

Yes, The reason I have already discuss !!
