I have a WinForms TreeView. The TreeView represents a summary of more detailed views and one of the visual cues I am using is to make a node's text bold or regular. The trouble is, if you change a node's font from regular to bold it clips the text as if it is trying to fit the bold text in the space for the regular text. A bit of browsi...
When I expand items in my treeview so that scrolling is necessary, a scrollbar appears. However, it doesn't scroll down for the newly expanded branch of items - they get cropped by the bottom of the control. So as I continue expanding items at the bottom of the tree, I have to keep manually scrolling down to see the new children. Anyone ...

I wrote a function which can yield the text of a tree view item, even if the tree view is in a remote process. The function allocates two chunks of memory in the remote process, populates a TVITEM structure (which is the copied into the remote process), sends a TVM_GETITEM message and finally reads the contents of the second remote memor...

I've been learning to use TreeViews, and these two types are often used for accessing a particular row of a tree. I don't really understand the difference between the two. My code is working--I convert back and forth between the two based on a function's required parameters--but not based on any real understanding of why. What is the di...

The problem is that in order to trigger the row-activate I first have to click on the row (triggering cursor-changed) and then do the double click, requiring 3 clicks.

I am looking for an algorithm that will automatically arrange all the nodes in an n-tree so that no nodes overlap, and not too much space is wasted. The user will be able to add nodes at runtime and the tree must auto arrange itself. Also note it is possible that the tree's could get fairly large ( a few thousand nodes ). The algorithm ...
