Silverlight obtains the row data selected by the DataGrid.

When I was doing a small demo today, a buddy in the group asked how to obtain the row data of the currently selected DataGrid. By the way, I tested it, we found that Sl is much more convenient than aspx! If the data you bind is entity, you can obtain the entity based on the current selected DataGrid. Code Paste.
Note that the trigger event is currentcellchanged.
Background code:
/// <Summary>
/// Obtain the selected cell data of the DataGrid
/// If the bound data source is an object, the selected current record is an object by default.
/// </Summary>
/// <Param name = "sender"> </param>
/// <Param name = "E"> </param>
Private void dgcate_currentcellchanged (Object sender, eventargs E)
{
DataGrid grid = sender as DataGrid;
Bookservice. Book = (bookservice. Book) grid. selecteditems [0]; // obtain the currently selected row data and convert it to the corresponding entity
MessageBox. Show (book. Title. tostring (); // print the attribute value of the object.
}
