I am using XamGrid and Persistence framework to save and load grid layout preferences in-memory and to isolated storage. What I observe is that the column sorting and alignments are saved but the GroupColumn are either not stored or not loaded back. The grids GroupColumns disappear on loading the preference. For example :
<ig:GroupColumn Key="Pricing">
<ig:GroupColumn.Columns>
<ig:TemplateColumn />
</ig:GroupColumn.Columns>
</ig:GroupColumn>
The Pricing group column disappears on loading saved grid preference. Kindly suggest.
I face the same problem
