how I can add a tree node with 2 lines of text, OR how to add a non-collapsable childnode to an existing child node. Basically my treeview consist of a list of groups, and inside each group is the contacts that belong to that group. Im trying to append a line of text to the existing contact when their status changes to busy, or not available.
example
// Current Contact List //
+ MyFriends
Timmy
Frank
Bob
What happens when I try to add the child node to the existing child node is it gives me the + sign so it can be collasped! I want the child node to be visible at all times. So it looks like this
// Contact List //
+ MyFriends
Timmy

suppose i have a tree that have a root node. that root node have 3 child nodes. each child node have 3 child nodes and so on say up to level 4. if i number each node from the root node and numbering from left to right, the root node being number 1 and the left child of the root being number 2, the middle child of the root being number 3 and the right being number 3. on the third level the left child node of the left child node of the root being number 5 and so on. if i have numbers 1 up to 13 and want to put each number into a node numbered the same i.e number 1 gets into the root node, number 2 gets into the left child node of the root and so on. how would i achieve that.

View 1 RepliesI have built a database structure that represents a category tree to help classify some of the data we have stored. The implementation is that each record in the Category table has a nullable foreign key back into the Category table to represent the parent Category of this category (one-to-many), essentially allowing for subcategories within a broader parent level. There is a CategoryMembership table that links a record in the Item table to its respective Category (many-to-many). I have created the DBML for this database, and it has a member access structure that includes the following:
