TcxCustomDataSummaryItem.EndUpdate Method
Applies all pending changes after a BeginUpdate procedure call.
Declaration
procedure EndUpdate;
Remarks
Every time you change a summary item setting, the parent data controller recalculates the corresponding summary and redraws the control to reflect the change. Enclose multiple summary item changes between BeginUpdate and EndUpdate
procedure calls to avoid UI flickering due to excessive redraw operations and improve performance.
BeginUpdate/EndUpdate Calls and Batch Changes
A BeginUpdate procedure call disables notifications and postpones all summary changes until an EndUpdate
call. A subsequent EndUpdate
call does the following:
- Re-enables change notifications and corresponding redraw operations
- Applies all changes made after a BeginUpdate call
- Sends corresponding notifications in a batch
- Redraws summary display text
Note
Ensure that every BeginUpdate procedure call is followed by an EndUpdate
call, even if an exception occurs.
