Hello,
We are using TMemTableEh with TDBGridEh in a tree mode. While searching in the grid with the option FilterOnTyping enabled an access violation is triggered.
For the search option we are using the OnKeyPress event to process directly the search text (example bellow):
type
THackDBGridEh = class(TDBGridEh)
end;
procedure TForm1.DBGridEh1KeyPress(Sender: TObject; var Key: Char);
begin
if not DBGridEh1.SearchPanel.Active and Key.IsLetterOrDigit then
begin
DBGridEh1.SearchPanel.Active := true;
with THackDBGridEh(DBGridEh1).FSearchPanelControl.FindEditor do
begin
Text := Key;
SelStart := Length(Text);
end;
end;
end;
With this the AV is present every time we type an alphabetic symbol. We manage to reporoduce the problem without the OnKeyPress event as well, but it is not constant.
We are using Delphi 10.2 Tokyo, EhLib 9.1.040. The tests were made with the DBGridEh.TreeView demo.
The access violation triggers in Unit MemTableDataEh, function TMemRecViewEh.GetRec, line 8749. We are attaching a screen shoot from the call stack.
Best regards
