In this method you won't get DataSet object in Update button click since it is declared in the View button click. So what you can do is, create a new dataset from the user entered values and update that to DB. Or store the dataset in session temporarily, and in update button click modify the dataset records and call DataAdapter.Update() method.

hi,
i have a question that ,how we can track the client machine..like say example
i have a web application which my clients have access to it and i want to treck some how .. that user are active or not with his activity..
means here server can track their users every time ...
is it possible here in asp.net ...
and also can we treck that user where user had closed that web application or system crash.. so how can i know that this user are no longer active with this application.

You need to use combination of session and application variables in Global.asax or in any HTTPModule. When user closes browser, no event will be fired on server. You can track session out from session_end event. This event will be fired when Session.Abandon() is called or when Session times out.

So keep an Application variable that holds Active users. When new sessions are created, Session_Start event will be fired. Inside this event you need to increase the application variable count. Application variable count should be decremented when session_end fires. To get active users print Application variable.

Which system crashes ? Client machine or Server. If client machine crashes, immediately session_end won't be fired. It will be fired when session end for the user. By default it will be 20mins. After that it will fire session_end event. But if server machine is crashing, I am sorry not even session_end, nothing will be fired.

Same way what I told in the previous posts. To understand how session and it's event works, better take a good ASP.NET book and learn.

Can you give me a example?is it same like i am storing in a cache variable ?

Like this

Cache["dt"]=dttable;
dttable=(datatable) Cache["dt"];

can i use ?

Session["dt"]=dttable;
dttable=(datatable) Session["dt"];

if it's possible is it good to store a datatable to a seesion Variable?

You can go with second method. Cache is not user specific. It will be common for all users accessing website. Session keeps datatable user specific.

This depends on the size of your datatable. If it is pretty big, then this method might cause performance issues. If it is small object then I think there is no issues.
