Hi
I'm new here.
I have been using HMG for a short time.
I have a problem with the 'tree' control.
I would like to be able to save data about the tree modified in the program in the DBF database.
Unfortunately I don't know how to do it.
I was hoping that the ParentValue propertie would help me. Unfortunately, it doesn't work properly in version 3.4.4 (32 bit) or 3.6 (64 bit).
To sum up, I want:
- build a tree based on data saved in the dbf database
- save the tree modified in the program to the database
I'm asking you for help.
regards
Krzysztof

Hi! Try to search on the forum. This problem was presented few years ago

Szia, csak néhány kulcsszó: base64, json.
Hi, just a few keywords: base64, json.

Krzysztof,

As Marek and Mizler said the forum is full of examples and solutions!

Hi Krzysztof!
To save kategories, I have a dbf with such a fields:
IdKategorii N 6
RodzajKategorii N 1 // określa wydatek/wpływ
IdKategoriiNadrzednej N 6
NazwaKategorii C
Nieaktywny L // used or deleted (hidden for user)

In such a structure you can save your tree

Sorry, guys
I think you misunderstood me.
I have a problem with the 'tree' control.
I would like to use this control to build a tree.
I would then like to save the data from this control to the DBF database so that I can recreate the tree.
I can't find the data defining the parent of the element in this "Tree" control.
Property 'Parent' in "Tree" control doesnt return this data.

Krzysztof, spójrz na ten post: https://www.hmgforum.com/viewtopic.php?p=65890#p65890, może będzie pomocny. Co prawda struktura drzewa jest zapisywana w json, ale nic nie stoi na przeszkodzie aby zapisać ją w DBF. Spróbuj to zrobić w ramach ćwiczeń z HMG.

Hurry !!!
Thanks edk
