Returns a value indicating whether the upload control is enabled.
true if the control is enabled; otherwise false.
Use the GetEnabled method on the client to determine an upload control's capability to respond to end-user interactions such as mouse hovering or clicks. The initial client availability state of the control can be defined using its server ASPxUploadControl.ClientEnabled property. Then, the state can be dynamically changed on the client side using the ASPxClientUploadControl.SetEnabled method.
