The DXGrid control supports Instant Feedback UI Mode - an asynchronous mode. With this mode, you will no longer experience any UI freezing. Data operations will be performed asynchronously, in a background thread and both the Grid Control and your application will always be highly responsive. The user can continue to scroll through records, and even re-sort, re-group and re-filter the control's data.
To provide visual feedback, the grid shows a wait indicator. Its type is specified by the WaitIndicatorType property. If this property is set WaitIndicatorType.Panel, the wait indicator is represented by a special panel displayed above the grid control (see the image below). Its layout and appearance can be changed via the WaitIndicatorStyle property.
