when the user clicks on the title button (column headings) in a UnidbGrid a drop down menu appears where the user can "sort ascending", "sort descending" and "columns" and then choose which columns to display etc
i use our own component TIUMGrid = class(TUniDBGrid) where the ColumnsChanged property from TUniBasicGrid with the new scope published.
In a project designer we added client events with ExtEvents for 2 new checkboxes (Sort and Filter) that appear in the drop down menu on the title button (of each column headings).
But when clicking on checkbox "Tri" (Sort) "columns" in the drop down menu becomes invisible and will never be visible again.
The needed instruction code (in OnAjaxEvent server event) below is responsible of that behavior :
IUMGrid1.ColumnsChanged := true;
How can i fix this bug ? Is it possible to add a very small zip files project to this topic (it will be more explicit) ?
This issue appears since we use the version 1.90 of uniGUI. In the past with version 0.9 of uniGUI it worked well.
