--- HOW to treat a SELF-referencing DB-TABLE within UNIGUI to allow flexible TREE-like interaction


Recommended Posts

Posted

Hi,

as I am planning to use UNIGUI in future projects, I am currently running a GAP-analysis based on

USER REQUIREMENTS. One requirement is defined by a structured organization of hierachical data.

 

The basic idea is to organize a comprehensive dataset (50000 records) in a TREE-like manner,

just like MS-WINDOWS-Explorer is used to navigate through 10000 of files stored in a: Drive, Folders, Subfolders. 

 

The solution should:

  1. - be performant without spending much time for ... preloading
  2. - interact (INSERT, DELETE, UPDATE) with a referencing DB-table
  3. - allow to ... visually ... change the sorting order by moving individual records UP and DOWN
  4. - savely handle all data while a set of changes might be cached in memory before changes are

written to the DB.

 

Any ideas how to handle this basic requirements in UNIGUI framework ?

ThanX Sherzod

please, have you got some more details to drill down for more informatiion.

 

Allready having a close look at the TUniGridsTreeGrid, I am asking "myself"

if there are any limitations concerning the depth of the hierarchy handled in

the first column of in an instance of TUniGridsTreeGrid.

 

Since you are an expert on UNIGUI, please, can you suggest other alternatives

with respect to the max numbers of records to be handled being in the range

of 10000 to 50000 ?

 

ThanX a lot.

Hi

 

I just played a little bit with UniDBTreeGrid to display some data in a tree-like manner

All is fine unitil now.

 

I also tried to append a record to this ..."grid" ,,, by the use of UniDBNavigator1.

Doing so, I did not ... visually .... recognize any NEW record to be appended by using the "+"-button. 

 

Upon saving an ErrorMessage is ´displayed stating: "Empty Row String" ?!?!

Did I miss some OPTIONS to select or did I miss some information ?

 

Best
