Checking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.

Add Nodes To A Treeview That Come From Different Databases?
Aug 25, 2009I am trying to add nodes to a treeview that come from different databases, but at the moment i am just trying to add the first set from the first database.
The link between the child and the parent is the ID column in the parent nodes access database this number is in a column in the child database called Section, i am trying (unsuccesfully) to use queries and If statements.
I am assigning the ID column from the parent database to the .Tag property of the parent node and then i am trying to use an if statement within the query "asking" if the parentNode.Tag = number in section column Then Add new node, but i haven't done it right. The code is below:
While RetVal3.Read
If RetVal3(0).ToString = SectNode.Tag.ToString Then

I need to know how I'd add a new child node to the parent nodes mentioned above.[code]
