Problem
Is it possible to show or hide a table column with 4GL?
I tried to use the UI associated methods but it doesn't work.
Solution
Yes, you need to read all columns from the table into DYNAMIC ARRAY OF ui.TableColumn:
| Code Block |
|---|
DEFINE t_columns DYNAMIC ARRAY OF ui.TableColumn
--get all columns
LET t_columns = ui.Table.ForName("tb_dynamic").GetTableColumns()
-- change column visibility
CALL t_columns[1].SetVisible(FALSE)
-- apply changes
CALL ui.Table.ForName("tb_dynamic").SetTableColumns(t_columns) |
