CodePudding user response：

The DataContext of a GroupItem has an Items property that contains all grouped items so you should be able to bind to the Note and orderid properties of an item in the group like this:

<TextBlock x:Name="GrpDate" ... Text="{Binding Name}" />
<TextBlock x:Name="GrpNote" ... Text="{Binding Items[0].Note }" />
<TextBlock x:Name="GrpNote1" ... Text="{Binding Items[0].orderid }" />
