This demo illustrates the compatibility of the DevExpress ASP.NET Grid View (ASPxGridView) with the Microsoft Ajax UpdatePanel.
In this demo, the ASPxGridView resides within the MS Ajax UpdatePanel control along with other controls. The total for the invoices selected in the grid control is automatically updated in response to the control's selection changes, which are processed on the server side (the grid control's SettingsBehavior.ProcessSelectionChangedOnServer property is set to true).
Note: To allow the MS Ajax UpdatePanel to handle ASPxGridView server requests, the grid control's EnableCallBacks property is set to false. This is necessary to make the UpdatePanel's child controls update properly, and to correctly preserve view state information. To provide visual feedback on the UpdatePanel's update status, the demo uses the MS Ajax UpdateProgress control.
