I have a treeview that is populated with a hierarchical list of regions and locations. Each region has its own list of regions and locations - you can think of these as analogous to a folder structure in windows (ie a region is like a folder than can have subfolders and files within it).My code to populate the structure is called only once (I've put in breakpoints and stepped through the code), however my treeview shows two sets of the data. When I query how many nodes there are at the top level of the treeview it tells me there is only one node, but clearly there are two. If I delete the node at position 0 in the list of nodes one copy of the tree disappears but one still remains and it this point the count of nodes in the treeview is reported as zero.
I have a toolbar associated with the treeview which includes buttons to expand all and collapse all using the built in methods of the treeview (expandall and collapseall), and these only act on the first set of nodes and ignore the second set even though I can manually expand and collapse them at run time.I have code in the AfterSelect event of the treeview and this does fire for even the phantom nodes.The other odd thing is that the code to populate the tree assigns a key to each node, and so I would expect the code to fail if it was creating duplicate nodes as it would have duplicate keys
I am working on a project and need checkboxes on childs only.Now I have this

View 4 RepliesI have a TreeView control on a form with two Root nodes. Both root nodes use the same ContextMenuStrip. The problem I'm having is that at runtime if I right-click on the root node that IS NOT selected, and select the option to add a child node, it gets added to the node that IS selected. My code for adding the child node is below.
Is there a way to have the control first SELECT the node that was right-clicked, or at least determine which node was right-clicked?

View 11 RepliesI am successfully able to pull images into a picturebox in my program and manipulate them in a variety of ways. What i need to be able to do is the following.
1) Pull images into a picture box on my main form and dynamically resize either the picture box or the image so that the image doesnt lose its scale when it comes in
2) Have a method of pre-screening an image to be loaded before it comes in so that i can change its size without losing scale .. ex.
if my image is 1200x1200 i do not have that much room on my form so i would want to say something like
if getimagewidth()>600 then
me.picturebox.width = getimagewidth()/2
end if

View 6 RepliesI am looking at creating a Dynamic Menustrip.I have managed to write the code to add subItems to a Item.

At the moment I want a message box to popup with the subItem's name that has been clicked. I.E If subItem3 is clicked, I want a msgbox to pop up with "subItem3".

View 4 RepliesI'm at a stage with my first real program where I'm putting some effort into the UI.I'd like to have a "meter", of "velocity" type, you know the ones in vehicles.I'm thinking of having an arrow that I've drawn in Illustrator pointing in a specific angles depending on values it gets from a database. i'm thinking of having on arrow pointing straight up, and two similar ones, only being diagonal in the picturebox (to the left and right respectively), thus enabling me to resize the picturebox and stretch the image. However that's not a pretty solution is it? Is there a way to place the arrow at an angle inside the picturebox, or the picturebox itself?
