Data grid sorting xaml

Question

In my application i have two data grid. The 1st data grid consists of different Locations, so selection of one Item in the 1st datagrid will populate the respective locations Name and Age in the second datagrid

The binding is done like this

C#

ObservableCollection<Location> LocationObj
{
get;
set;
}

the above mentioned LocationObj is bound to the 1st datagrid and the selecteditem is bound to the SelectedLocation Property

C#

Location SelectedLocation
{
get;
set;
}

The class Location contains an ObservableCollection of name and age 3
In the second datagrid the ItemsSource is set to SelecetedLocation.Details which contains the ObservableCollection of age and Name.
When ever the user edits an Age, I would like the SelectedLocation to be sorted by Age.

How can i achieve this??

If you want to sort a column on the WPF Datagrid, you can try this link.

Sort WPF Datagrid column programmatically[^]

By the way, do not put your question text inside a code block. That is meant only for code alone. Thanks.

Sory the link you provided will is applicable only when u have one grid .. when ever selection of the second grid changes the collection view source is not helping much ..

Well only your second grid's age column requires sorting I guess? You aren't sorting anything in the first because it contains locations right?

yeah..
when i select each item of the first grid the second grid values will change..
CollectionView source helps only to sort first time.. that is on load .. the first grid's first item is selected .. So now if i change the second grids age coloum the values are sorted but again if is select the first grids another location item .. the second grids sorting is not workin any more :(

Well it looks to me that when the ItemsSource is changed, the sorting doesn't seem to exist. How about you add a umm PropertyChanged event handler for the second grid ItemsSource and repeat the sort process.

Sorry ididnt understand :(

One easy way is to convert the ItemsSource bound property into a dependency property. In that, add a property changed event handler. Inside that you can sort it again.
