I have a TListView
linked in LiveBindings with a TFDMemTable
. I load data in the FDMemTable using LoadFromFile
(I have for example 20 record).
When I delete a record from the FDMemTable, the RecordCount
is decreased but the TListView
is not refreshed, it continue to display the 20 records loaded on the LoadFormFile
.
If, with the FDMemTable: I .SaveToFile
, .Close
, and reload with .LoadFromFile
, the TListView
now display the change.
This is the same behavior if I use the CachedUpdate
of FDMemTable or not.
I've tried to call TFDMemTable.Refresh
and TListView.Repaint
without succes.
Is it possible to call the TListView
to refresh his "linked" set of data ?
When I delete a record in the FDMemTable, why no visible refresh occur on the TListView
?
EDIT: I must add a thing, the record is deleted programmatically.
The desired functionality is to delete sone unwanted record in the FDMemTable
and display the remaining record to the user with the TListView
.
In LiveBindings Designer, by linking the Synch
of the ListView
to the *
of the FDMemTable
, the ListView
now display the resulting record.
Also in my last algorithm, because I use .BeginBatch / .EndBatch
(that disable data-aware refreshing), while processing data for removing unwanted record I've to disable the LiveBinding link temporarily (cause I use different sorting index whitin the processing of the data): LinkListControlToField1.Active := false;
and "re-link" it after processing: LinkListControlToField1.Active := true;
