Something seems to have changed with drag and drop in VCL 14.1.2. I have a Grid with a Single Column View which has several fields in the view. In the previous release with DragMode set to dmAutomatic I could click anywhere in the record and drag it (Editing and Inserting is set to false).
Since installing 14.1.2 I can now only drag the record if I click on the column header. See annotated screenshot attached.
We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.
Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.
Is the fix correct? I get an exception: E2003 Indeclared identifier: 'AlwaysShowEditor' in the modified fix above:
procedure TcxGridViewLayoutItemDataCellViewInfo.StateChanged(APrevState: TcxGridCellState);
begin
CalculateParamsNeeded;
inherited StateChanged(APrevState);
if GridView.OptionsBehavior.AlwaysShowEditor and
(State = gcsPressed) then
MouseCapture := False;
AlwaysShowEditor mode is enabled <<<<<<<<<<<<<<<< the exception is here.
end;
It seems that you are right. The fix is incorrect. The problematic code is just a comment. Here is the code that should help:
DelphicxGridViewLayoutContainer.pas
procedure TcxGridViewLayoutItemDataCellViewInfo.StateChanged(APrevState: TcxGridCellState);
begin
CalculateParamsNeeded;
inherited StateChanged(APrevState);
if GridView.OptionsBehavior.AlwaysShowEditor and
(State = gcsPressed) then
MouseCapture := False;
//AlwaysShowEditor mode is enabled
end;
