Hi All,
I'm developing one application in asp.net 2.0
In that application logged in user can view the pages. If the user close the page with out signing out means how can I maintain their login status?
If I use the javascript in body unload means, I have to implement this script in many of the pages.
Give some better idea to solve this prob.
Thanks in Advance

Are you maintaining any DB flags for user status ? Usually you need to check the session existence in each page_load. If session is not exist, redirect user to the login page.

Yes,Maintain the username in a session,if there is a null value means,I will redirect to login page. There is no prob in that.
What I want is ,if the user suddenly used the window after logged in means how can I capture their status? and how to update the Database?
I updated the Databse for login status in sign out button click and session_end of Global.asax.
There are many pages in my application,after login.So How to update the database when the user suddenly closed the browser window?

There is one more way
Create a base class that will have a method which check the session if user is logged in or not call that method from page load of base class
Now your page should derived from this base class
Now if user closes the browser you want to sign out user
Create a cookie like person id for the session level and check that cookie
if user close the browser without sign out, then cookie will also get deleted now if he open in new browser the cookie will not be available
Thanks and Regards

First tell me what problem are you facing when user closes the browser without logged out. And open the application in new browser.

No friend, i don't see any other idea as you need to use client side state management for this as server never knows about the browser states whether it is open or closed

Ya you should not logged out the user but at certain interval of time,
If it exceeds more than 20 min(depends on business ) your session should expired so user need to logged in again.

If system get shut down then you should not maintain the status as logged in user. The user should not logged in by default after Restarting the machine. As there should be a new session for that user

Hai,
How to calculate city and country ip address of the system.

Hi
I have a hyperlink field which is in a template field in a gridview
I have given it an ID
However in the c# code behind I cant seem to reference it, why would this be?
I want to be able to control it using the c# code
thnaks!
|
|
|
|
|
Since it is in the gridview, you should use FindControl() method to find the control from an id.
HyperLink hyp = GridView1.Rows[index].FindControl(id) as HyperLink;
|
|
|
|
|
Hi
Should I use [index] or should I put the number of the row in there as it hasnt found the control.
thanks!
|
|
|
|
|
You should put the row index. If you want to find the control from 5th row, index would be 4.
|
|
|
|
|
but if I want to do it for the whole column, how would I do that? gridview.columns[x] yeah?
|
|
|
|
|
Then column index also should be specified. Something like
GridView1.Rows[inde].Columns[index].FindControl(id)
|
|
|
|
|
How could I disable every row rather then just the one row?
thanks

What do you mean by that ? Explain the problem in-detail.
|
|
|
|

Basically I have a gridview which would contain 20 rows
One of the columns is a hyperlink
If the user doesnt have the correct rights I would like to disable the hyperlink for every row(i.e. disable the column)
Howe could I do that?
thanks

Check RowDataBound event which will be fired when rows are bounded. In this event, check for permission, if there is no permission, find the hyperlink and set it's enabled property.
|
|
|
|
|
yeah but the problem is, i cant find the hyperlink the code isnt owkring below
HyperLink hyp = GridView4.Rows[?].FindControl(hyperlink);
I need to find the hyperlink in all the rows not just one how can I do this?
thanks
|
|
|
|
|
RowDataBound event will be fired for each row. You need to check the event parameter passed to that handler. If you are not doing this on row data bound event, you have to iterate through each row and do the checking.
|
|
|
|
|
sorted it:
protected void Gridview4_RowDataBound(object sender, GridViewRowEventArgs e)
for (int x = 0; x < GridView4.Rows.Count; x++)
{
GridViewRow row = GridView4.Rows[x];
HyperLink hyp = ((HyperLink)row.FindControl("hyperlink"));
hyp.Enabled = false;
}
cheers for your help
