JavaScript/jQuery Autocomplete Methods
beginUpdate()
Postpones rendering that can negatively affect performance until the endUpdate() method is called.

- DevExpress.ui.dxAutocomplete.defaultOptions({
- device: { deviceType: "desktop" },
- options: {
- // Here go the Autocomplete properties
- }
- });
You can also set rules for multiple device types:
- DevExpress.ui.dxAutocomplete.defaultOptions({
- device: [
- { deviceType: 'desktop' },
- { deviceType: 'tablet' },
- { deviceType: 'phone' },
- ],
- options: {
- // Here go the Autocomplete properties
- }
- });
endUpdate()
Refreshes the UI component after a call of the beginUpdate() method.
The beginUpdate() and endUpdate() methods reduce the number of renders in cases where extra rendering can negatively affect performance.
