You can handle the SelectedCellsChanged event to be notified when the collection of selected cells is changed. If the selection includes full rows, the Selector.SelectionChanged event is also raised.
You can retrieve the AddedCells and RemovedCells from the SelectedCellsChangedEventArgs in the event handler.
The following example shows how to handle the SelectedCellsChanged event and clear the values in the newly selected cells.
<Grid> <DataGrid Name="DG1" ItemsSource="{Binding}" SelectionUnit="CellOrRowHeader" SelectionChanged="DG1_SelectionChanged" SelectedCellsChanged="DG1_SelectedCellsChanged" /> </Grid>
private void DG1_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e) { //Get the newly selected cells IList<DataGridCellInfo> selectedcells = e.AddedCells; //Get the value of each newly selected cell foreach (DataGridCellInfo di in selectedcells) { //Cast the DataGridCellInfo.Item to the source object type //In this case the ItemsSource is a DataTable and individual items are DataRows DataRowView dvr = (DataRowView)di.Item; //Clear values for all newly selected cells AdventureWorksLT2008DataSet.CustomerRow cr = (AdventureWorksLT2008DataSet.CustomerRow)dvr.Row; cr.BeginEdit(); cr.SetField(di.Column.DisplayIndex, ""); cr.EndEdit(); } }
