DataFieldParentID

[Regeesh Joseph]

Hai,

I have a dataset having fields in the following way :

Flight_Id    Flight_Name   Sector_Id      Sector_Name
----------------------------------------------------------------------------
1                    A                        100                a
2                    B                        200                b
3                    C                        300                c

I want a treeview with Flight_Name as parent nodes and corresponding sector_Name as its child nodes.

Can anybody give some sample code to bind the treeview like this?

Thanks & regards,
Regeesh Joseph

What is the use of DataFieldParentID in the case of child node binding?

Hi Regeesh Joseph,

Well, you probably will have to change the relation a bit (if this is not possible than you can extract the needed view of the data with some more complex query).
Since you can only bind the treeView to a single data source, you can not divide the two types of nodes in different data sources.

But you can always bind the treeView with custom method running on the server, extracting data from the data source and dynamically creating nodes of it.

Hope this is helpful for you!
