Exempel
I följande exempel visas hur du SelectedCellsChanged hanterar händelsen och rensar värdena i de nyligen markerade cellerna.
<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();
}
}
Private Sub DG1_SelectedCellsChanged(sender As Object, e As SelectedCellsChangedEventArgs)
'Get the newly selected cells
Dim selectedcells As IList(Of DataGridCellInfo) = e.AddedCells
'Get the value of each newly selected cell
For Each di As DataGridCellInfo In selectedcells
'Cast the DataGridCellInfo.Item to the source object type
'In this case the ItemsSource is a DataTable and individual items are DataRows
Dim dvr As DataRowView = DirectCast(di.Item, DataRowView)
'Clear values for all newly selected cells
Dim cr As AdventureWorksLT2008DataSet.CustomerRow = DirectCast(dvr.Row, AdventureWorksLT2008DataSet.CustomerRow)
cr.BeginEdit()
cr.SetField(di.Column.DisplayIndex, "")
cr.EndEdit()
Next
End Sub
Kommentarer
Du kan hantera händelsen som SelectedCellsChanged ska meddelas när samlingen av markerade celler ändras. Om markeringen innehåller fullständiga rader Selector.SelectionChanged utlöses även händelsen.
Du kan hämta AddedCells och RemovedCells från SelectedCellsChangedEventArgs i händelsehanteraren.
