Hello guys,
I have a particular scenario to display hierarchial information in grid. Consider the following table structure and the sample data.

Table structure

ObjectId - Primarykey
Parentid
description

Sample data

objectid parentid description

---

1 null Parent 1
2 1 child for p1
3 1 child for p1
4 null Parent 2
5 4 child for p4
6 5 child for c5
7 6 child for c6

So, from the above data, objects 1 and 4 have parentid as null. So, they are the base parent objects to be displayed in the grid. Objects 2,3 are child for parent object 1. So object 2 and 3 should be nested within object 2. Similarly object 5 should be nested within parent object 4. Object 6 has the parentid as 5. So it should be nested within the child object 5. Also object 7 should be within object 6. So the nesting can be n levels and all this nesting should be visible inside the grid. The grid row holding the parent object should have a + sign and on click of that + sign, the immediate child objects should be visible, using javascript.

The grid should appear like this

objectid description

• 1 parent 1

  objectid description
  2 child for p1
  3 child for p1

• 4 parent 2

  • objectid description
    5 child for p4

    • objectid description
      6 child for c5

      • objectid description
        7 child for c6

Please provide a solution. I am working with asp.net 2005,c# and oracle 10g.

Please help me ... its very urgent...

Hi guys, I have an interesting scenario. I have a web application created with asp.net 2005. There will be more users who will be using my web application. User's can use the login page to log in to the application and use sign out to logoff the application. My question is :- if for example a user from a machine 1 with an ID "Shankar" has signed into the application by providing the correct credentials and the same user is signing into the application with the same credentials, but this time from a differant machine. How should i prevent this from happening. Please help me out of this problem. Regards Shankar
