将数据网格值绑定到另一个数据网格

Question

I have two datagrids. The first contains the columns:

name, price, rank, rating, groupNumber ..... and many other columns

And the second contains:

name, rating, groupNumber

Suppose I selected a row in the first datagrid and for that row GroupNumber was 6 , is there a way to display all the rows with groupNumer=6 using data binding in second datagrid?

What would be the best way to do such thing?

Right now I doing it by selecting all the rows that have the same group number as the selected row in the first grid then copying those rows to another datatable then setting it as the source of the second grid.

Here is how i am doing it right now on row selection changed for the first grid:

int gnum = //get the selected row gnum value
secondgrid.ItemsSource = firstgrid.Select(String.Format("gnum={0}", gnum)).CopyToDataTable().DefaultView;

您可以将相同的源绑定到两个DataGrid，但是在第二个中使用基于第一个DataGrid中当前行的过滤器
