Multi-Select Lookup using a Tree

Hi folks

I am hoping to earn a Christmas bonus. I have concluded that my chances will improve if I create a multi-select tree lookup for ISV solution X. There are many resources on multi-select lookups using a grid. But I haven't found anything on trees.

Does anyone have a link, hint or example?

Thanks for your attention

I've used tree lookups, multi-selection lookups and multi-selection trees, but not a multi-selection lookup with a tree.

I guess you can implement something like SysLookupMultiSelectCtrl which will use another class instead of SysLookupMultiSelectGrid.

Nevertheless I would try to avoid this design. For instance, if you open a form by a button, you have much better control over it (e.g. for sizing) than when using a lookup. And I'm not a big fan of multi-selection lookups in general.

Lol hi boss. I guess we can discuss it in the next company meeting? I am thinking something in the direction of 450% ...

Martin - thanks for the reply. You mentioned you have built multi-selection trees. Is that difficult? I mean a multi-select grid is easy (the property is on the element designer), but I don't know where to start with a tree. I have looked at MS docs and then from there I looked at the tree used with SysConfiguration (which looks great - I'd love to build something like that). But it is exceedingly complex.

Ahhh I see there is a "Check Box" property on the FormTreeControl. So I guess it is not so difficult at all. I think I will take your advice and build a form. Thanks.

Yes, using the checkbox is the way.

You can find tutorial_Form_TreeControl in older versions of AX; it shows working with checkboxes, among other things (if I remember it correctly). Unfortunately it doesn't exist in D365FO anymore.

Martin I have further questions if you don't mind.

For context: I am building analysis logic on bank account transactions. The user needs to be able to select which accounts he/she wants to view. So I had the idea that the user must be able to select bank accounts, legal entities and bank groups. Which brought me to the multi-select tree lookup. For example the user can select AccountA from USMF, BankAccountGroupC from GBSI, AccountB & AccountC from USSI and the entire USRT. Thus the root nodes will be legal entities, sub nodes bank groups and then bank accounts.

If I am going to create a form for the selection, what form pattern do you suggest? Custom? Cause I also feel like it should be a dialog...

Any resources on building trees with your stamp of approval?

The above point brings me to my last question. How do you remember stuff you learned or discovered? The reason I ask is I have built quite a few trees in my AX lifetime, and in my opinion I was quite good at it. But it is so long ago that I need to do all the research again. Or do you have perfect memory? I often search my own profile on this forum for questions I asked before. Start a blog?

Which pattern to use depends on how you decide to model the GUI. The tree control can be used in many patterns, including Dialog - Basic (with Toolbar and List subpattern used for the content group).

A useful resource may be mfp's How to use a FormTreeControl. It's very old, but I think that these classes didn't change too much.

Regarding memory, I'm in the same situation as everybody else. While I do remember quite a few things, the amount of information I meet every day is insane and it's impossible to keep track of everything. I sometimes look at my own code written a few months back and I would swear that I've never seen it before... :) The same it is with some parts of AX. I too spend lots of time trying to figure out things that I knew a few years back but didn't use recently.
