ASPxClientGantt.Refresh Method

Reloads data from the data source and redraws the Gantt layout.

Declaration

Refresh(): void

Remarks

Call the Refresh method to update the Gantt control layout. The Refresh method sends a callback to the server and re-binds the Gantt control to the data source.

The following example updates the Gantt‘s layout when a user clicks the “Refresh” button. The button’s Click event handler calls the Refresh method. Note that the button’s AutoPostBack property is set to false to prevent the control from a round trip to the server.
The image below illustrates two web pages with the Gantt control. If a user changes tasks on the first web page, the control on the second page updates its content when the “Refresh” button is clicked.
