Hello,
I want a tree view to load infrormation of a data base. I want to do the same as working with the menu control, having a main header (main directory) and submenus (folders or files).
Is it possible to to this ?
Thanks a lot.

Hi,
There is no difference when populating to the menu or to the TreeView. They are exactly the same when it comes to data binding.
Thanks!

I already made this work as the menu control. Now I want to get the Id of the checked nodes with GetCheckedNodes, but I don't know how to do this. I tried to put them in a list box by using databind, but nothing is displayed. My database has an Id, but I don't show it in the text displayed on the TreeView control, I want to get my internal Id of thw checked items.
For example, my DB is like this:
ID TEXT
1 Articulo 1
2 Articulo 2
3 Articulo 3
4 Articulo 4
I displayed the field TEXT but I want to get the field ID of the checked box text, is possible to do this ?
Another issue, is when I check a "father" node all the children gets checked, but when I uncheck the father the children do not get unchecked. Its posible to do this ?
Thanks a lot for your support.

Hi,
You would simply use a DataBinding object to map the ID to the TreeNode's Value property. That way each TreeNode displays your TEXT field, but keeps the corresponding ID field value in its Value property. On the server side you would then check each node's Value property to get your internal ID.
As for the second question, you need to set the TreeView's AutoCheckChildren to false.
Thanks
