View 1 RepliesI am trying to learn how to populate a tree from a database, I did this same thing back in Vb6 and am trying to learnhow to do it in VB.Net, but I am having trouble with the code. From looking on the web I have piced this together, but I think it may be far off. It just jumps out put leaving the tree blank; and it gives no error message. I put in a try error catch and it cannot convert the data to a double, but even if I take this out it does not work. It is stuck at the line with: dr("CustomerID") <> hID I was using this to check for a parent node, I can take it out, but it still does not work; I am afraid that I am be way off here. I am using the Nothwind database.

View 4 RepliesI have a requirement. I have a wcf method add and delete which takes person object as parameter. I retrieve these methods into a tree view.

Requesting help for this situation.
Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?

So is there any way that newly added node will be added Editable?

I'm looking for a way to create the treeview structure in memory with a classes, so I can loop through them, like with a collection and easily load the data into a treeview, listview, datagridview or simply work with the data in the background.
There's a treenode class that I could use, but I've noticed that when I have a lot of data in the nodes, it has a lot overhead when for example serializing, because it also saves the checked state, imageindex of the nodes and things like that, which I never need. The saved file is about 10 times bigger than the actual data, which is not acceptable.
