WPF: Master - detail view with two datagrids and in MVVM
- by EV
Hi,
I'm trying to write a master - detail control that consists of a master datagrid and the detail datagrid. My scenario was following - I used the SelectedItem and bound it to a property in ModelView. The problem is - the SelectedItem in ViewModel is never used, so I can't get the information which item is selected in a master datagrid and cannot fetch the data for thos selection.
The code is below:
<toolkit:DataGrid ItemsSource="{Binding}" RowDetailsVisibilityMode="VisibleWhenSelected" SelectedItem="{Binding SelectedItemHandler, Mode=TwoWay}"></toolkit:DataGrid>
And in ViewModel
private CustomerObjects _selectedItem;
public CustomerObjects SelectedItemHandler {
get { return _selectedItem; }
set
{
OnPropertyChanged("SelectedItem");
}
}
The code in SelectedItemHandler is never used.
What could be the problem? Should I use another approach to create master - detail in MVVM?
