David,
I think your intuition is good here; when you have choices broken into groups or categories, and especially when the number of these groups might vary so that you can’t design a static dialog setup for just these groups, then a treeview (a multi-select treeview in your case) does sound like the best choice. Perhaps you’ll want to add a command button so that it will read out to the user a summary of the items which are selected under the current top-level grouping, if that information makes sense for a user to want in your application. Good luck, Chip p.s. I think there are several apps from GW (Aaron) which show the use of treeviews (one called TreeView, another is UIDesign, and you can still get to older versions of the appGet app to see their source code, and it used a TreeView).

Well fact is, that the project is going to have more like 50 entries on the main level, and up to five sub-level on some of the entries. That is why, I don't think a load of checkboxes would do. It would not even fit into a screen. The total list, including all sub-lists, holds more than 300 entries. And, you are not just to decide Shirt, Pant or Socks. You will also choose the color, and if available the shade. So, you can choose only pants (with no color choice), and Shirt with the color green, and for socks, you can choose both black and Blue. Do you choose blue socks, there is the choices of Skyblue, Navy or Ocean blue. If you have the chance, please look at the short list I provided, and pay attention to the levelling of each entry, and you will see how they are connected with each other. I could have made a multi-selection list, but then the user will have to scroll through a ton of colors, for each piece of cloth. All of this, was the reason, why I thought of a treeview, as it would give the user a quick way of scrolling down to the cloth he wanted, then expand that one, and check the colors he wanted. But apparently I was not explaining this well enough. Thanks anyway for the ideas. They would have worked in a simpler project, but I have a feeling it would be hard to have to tab through several hundred checkboxes for putting together an outfit. :) Regards, ----- Original Message ----- From: Rod Hutton <mailto:[email protected]> To: [email protected] Sent: Saturday, March 30, 2013 6:20 PM Subject: Re: Suggestion needed, is a Treeview the right thing? Hi David, Here’s a lazy man’s point of view: why not just have 3 groups of checkboxes in one dialog; the first group (at the top of the dialog) would be “shirt”, the second (below the “shirt” group), would be “pants,” and the third group (below “pants”) would be “socks.” So, all you would need to do is tab around and check/uncheck to your heart’s content.

I am about to start out on a new project. But I want to do things the better way, first go. .) If I, in short terms, would describe the feature I am trying to figure how to, let me give this example. Imagine we have three main levels. Let's for the ease of the example, say they are: Shirt Pant Socks . Now imagine, we have subcategories of each, giving different colors, and maybe even subcategories from there, giving the shades. So, the whole structure, would look like this: Shirt Green White Blue pant green red black socks green light dark white blue sky ocean navy Black Yellow. My first idea, would be to put all of this into a treeview. Thing is, that I wanted to have the chance of "checking" the different entries. That is, a person should be able to put a check mark, at the Green, under both Shirt and Pant. Maybe even check both Green and and white, for the shirt, and green for the pant. I have never constructed a treeview, and I don't even know, if it is possible in a rather simple way - to accomplish what I here am attempting to do. Hence, my first question would be, is a treeview the right way to go? Secondly, is it even possible to do what I want? And thirdly, is there any tutorial, or scripting samples, that would address this kind of task. Preferably, something that does not contain thousand of lines, in a high-tech and fancy script. Ok, I do understand, I would have to deal with dialogs, and treeviews or whatever, from an XML. Fine enough, but what would be suggested from some of you more experienced developers out there? Thanks alot for any feedback,
