TcxLookAndFeelController.EndUpdate Method
Applies all pending changes and redraws all forms and controls after a BeginUpdate procedure call.
Declaration
procedure EndUpdate;
Remarks
Every time you modify a global look & feel setting in the Skin Controller component, all application forms and DevExpress controls redraw their 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 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 all affected forms and controls in an application
Note
Ensure that every BeginUpdate procedure call is followed by an EndUpdate
procedure call, even if an exception occurs. Otherwise, the application remains frozen and unresponsive.
Code Examples: Apply a Skin and its Palette
The following code example applies the WXICompact
skin and its Sharpness
palette to an application:
dxSkinController1.BeginUpdate;
try
dxSkinController1.NativeStyle := False;
dxSkinController1.SkinName := 'WXICompact';
dxSkinController1.SkinPaletteName := 'Sharpness';
finally
dxSkinController1.EndUpdate;
end;
Alternatively, you can call the SetSkin procedure:
dxSkinController1.BeginUpdate;
try
dxSkinController1.NativeStyle := False;
dxSkinController1.SetSkin('WXICompact', 'Sharpness');
finally
dxSkinController1.EndUpdate;
end;
