NuGet Package: DevExpress.Web
A Object representing the control which forced a postback.
The ASPxNavBar.GroupCommand event fires when a control residing on a group’s template raises the Command event. This can occur when the Button control residing on a template for a group is clicked. In this instance, the CommandSource property returns the clicked Button control. This can be used to identify the control that forced a postback, if there are several controls residing on a template.
