beginUpdate()
Postpones rendering that can negatively affect performance until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.

defaultOptions(rule)
Name | Type | Description |
---|---|---|
device | | |
Device parameters. |
options |
Options to be applied. |
defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Gantt UI component in an application executed on the desktop.
- DevExpress.ui.dxGantt.defaultOptions({
- device: { deviceType: "desktop" },
- options: {
- // Here go the Gantt properties
- }
- });
You can also set rules for multiple device types:
- const devicesConfig = [
- { deviceType: 'desktop' },
- { deviceType: 'tablet' },
- { deviceType: 'phone' },
- ];
- devicesConfig.forEach(deviceConfig => {
- DevExpress.ui.dxGantt.defaultOptions({
- device: deviceConfig,
- options: {
- // Here go the Gantt properties
- }
- });
- });

- ...
- let element = document.getElementById("myGantt");
