Feature Request: Extend IsLoading functionality across more data bound components

[DanRogers99]

Describe the solution you'd like
Datagrid IsLoading is a very useful piece of functionality. Could this be extended to more components in the library?

I have identified components that could be useful to also have this functionality:

• AutoComplete
• DropDown
• ListBox

Could we add the IsLoading property to DataBoundFormComponent?

Describe alternatives you've considered
Alternatively we could create a wrapper component that contains the inline spinner
