Hi,
I am relatively knew to the ASP .Net world, so I may be going about this all
wrong, but I need to figure this out anyway.
I am using a IE Web Controls TreeView. I have a class that manages the
TreeView and syncs it with the data that I have in some objects that
correspond to the TreeView Nodes. I have put the TreeView in a Web Control.
In the control, I utilize a class that manages the data for the TreeView.
So in other words, the desired behavior is this: The User changes the Node
on the TreeView. That Node corresponds to an object in my app (i will call
is myAppObject). So the object manager (myAppObjectManager) will have
((myAppObjectManager.CurrentSelection.Name == TreeView1.Node.Node.Text) =
true) (semi-psuedo C# code). In other words, there is a one to one
correspondence in this relationship (furthermore, myAppObject is not a
TreeNode).
The problem is that as soon as a Node is expanded or a Node Selection
changes, the webform (that contains the custom treeview control) rerenders
before the TreeView1_Expand or TreeView1_SelectionChaged fires (in the
custom control). It is in those events that i call myAppObjectManager and
set its current selection. So when the webform rerenders is has the
previous selection for myAppObjectManager.CurrentSelection (because the
event fired after the last time the page rerendered).
I have tried firing an event once the data in
myAppObjectManager.CurrentSelection changes. The event fires, but only
after the page has rerendered (so consequently, the webform never has the
true myAppObjectManager.CurrentSelection).
I have been tring to use RaisePostBackEvent in myAppObjectManager, but I
cannot get this to work correctly either.
My desire is to have the data update, then the page rerenders. Is this
possible? If not, how can i force a refresh? Or force a redirect to itself
(webform).
Thanks for the help,
Paul
