TcxLookAndFeel.EndUpdate Method

Applies all pending changes and redraws the affected control after a BeginUpdate procedure call.

Declaration

procedure EndUpdate;

Remarks

Every time you modify a look & feel setting at the level of an individual control, the control redraws its content to reflect the change. Enclose multiple look & feel setting changes between BeginUpdate and EndUpdate procedure calls to avoid UI flickering due to excessive redraw operations and improve performance.

BeginUpdate/EndUpdate and Batch Changes

A [BeginUpdate] procedure call disables notifications and postpones all changes until an EndUpdate call. A consequent 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 the affected control

Note

Ensure that every BeginUpdate procedure call is followed by an EndUpdate procedure call, even if an exception occurs. Otherwise, the affected control remains frozen and unresponsive.
