XamGrid Grouping does not reflect underlying data changes

Hi,

The scenario is like this:

At runtime I enable grouping based on a column (or nested columns).
The datasource changes which causes the columns to change.
This change is not updated for the grouping column.

Is there a way in which the grouping can be refreshed for data updates ? Or is there a propertyt that needs to be enabled to update regrouping for a column change for the rows ?

Thanks for the reply,

I have tried adding XamDataGrid.Records.RefreshSort(), don't seem to find RefreshSortPosition method. But this still does not work.

I have added a sample project that explains the scenario. Let me know what needs to be added . In the sample code if you Group by BasePrice and click start the baseprice changes but the rows grouped remain the same.

Hi Avinash,

Excuse me for the mix-up I was thinking of the Silverlight XamGrid. For the WPF XamDataGrid the designed behavior is the same nad you can use the XamDataGrid.Records.RefreshSortPosition method.

Please let me know if you require any further assistance with this.

Best regards Petar.

Thanks Petar,

I don't see any method InvalidateData for WPF xamGrid. Is there something I am missing?

I can see only the below methods:

InvalidateArrange, InvalidateMeasure, InvalidateProperty, InvalidateVisual
