If the RadSpreadsheet is declared as a child content in the RadBusyIndicator, there isn't any tab selected as active in the SheetSelector.
Workaround: Declare the busy indicator after the RadSpreadsheet not as its child.
For example, instead of:
<telerik:RadBusyIndicator>
<telerik:RadSpreadsheet x:Name="radSpreadsheet" />
</telerik:RadBusyIndicator>
Do:
<Grid>
<telerik:RadSpreadsheet x:Name="radSpreadsheet" />
<telerik:RadBusyIndicator />
</Grid>
This behavior was originally reported over 10 years ago and has not received significant demand or follow-up from the community since then. Considering this and the availability of a workaround, we are unable to prioritize it over more impactful and widely requested improvements.
If this limitation is still affecting your scenario, please share additional context or use cases. This will help us better assess the severity and reconsider prioritization in the future. Thank you!
