if you are using ObservableCollection, if you add item to the collection, it should automatically appear in the DataGrid

I am using the list as the item source for the datagrid. . .

in page() i wrote this. . .

List<Data> source = new List<Data>();

int itemsCount = 10;

for (int i = 0; i < itemsCount; i++)

{

source.Add(new Data()

{

FirstName = "First",LastName = "Last",

Age = i,

Available = (i % 2 == 0)

});

}

dg.ItemsSource = source;

I have Defined data Class separately. . .

Regards,
Pradeep.

add item to the list and reset the ItemsSource

dg.ItemsSource = null;

dg.ItemsSource = source;

I would like to add 2 rows of summary information to the bottom of my DataGrid. Technically, I could calculate the my summary values, instantiate a couple of fake objects and Add them to the ObservableCollection, but that seems like a hack.

It would be nice to be able to create a footer, but I don't see that option anywhere. Any other ideas?

As lee mentioned, you can use ObservableCollection<Data> instead of List<Data>. Resetting the ItemsSource is an expensive operation it's better to use an ObservableCollection and add/remove from it. You can simulate an empty row by adding an empty Data object to it.
