Like other DevExpress WinForms controls, the DashboardViewer control supports touch-input devices. This not only means that end-users can use touch gestures to operate the DashboardViewer, but the control itself can be switched to Touch UI mode. In this mode, all UI elements will tend to increase their sizes and margins. The following image illustrates the DashboardViewer with the Touch UI mode enabled.
The following global settings affect the touch functionality.
The WindowsFormsSettings.TouchUIMode static property specifies whether touch UI mode is enabled.
You can use the WindowsFormsSettings.TouchScaleFactor property to specify the scale factor used to calculate the size and distance between specific control elements when touch UI mode is enabled.
The WindowsFormsSettings.ScrollUIMode specifies the UI mode in which scroll bars are displayed. You can set in to Touch in order to enable scrolling using touch gestures.
Use the WindowsFormsSettings.ShowTouchScrollBarOnMouseMove property to specify whether or not scroll bars appear on screen when an end-user moves the mouse pointer over the scrollable content.
