TcxCustomLookAndFeelController.BeginUpdate Method
Postpones all control redraw operations that reflect look & feel setting changes until an EndUpdate procedure call.
#Declaration
procedure BeginUpdate;
#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 Begin
procedure call is followed by an End
#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.UseSkins := True;
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;
