WPF DataGrid using DataTable as a data source, add the CheckBox column to use Delete to delete the line

First CanUserDeleteRows set to False,

Second set KeyUp event

And custom modified as follows DataGrid.Columns

 <DataGrid  x:Name="DG" KeyUp="DG_KeyUp"    ItemsSource="{Binding }" CanUserDeleteRows="False"     AutoGenerateColumns="True">
            <DataGrid.Columns>
                <DataGridCheckBoxColumn   Header="SingleCheckBox">
                    <DataGridCheckBoxColumn.CellStyle>
                        <Style  TargetType="DataGridCell">
                            <Setter Property="ContentTemplate" >
                                <Setter.Value>
                                    <DataTemplate>
                                        <CheckBox x:Name="CB"  Click="CB_Click"/>
                                    </DataTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </DataGridCheckBoxColumn.CellStyle>
                </DataGridCheckBoxColumn>
            </DataGrid.Columns>
        </DataGrid>

 

In CS Page modified:

Defines a List <DataRow> dataRow set Row to store the DataTable

CheckBox modify the Click event

as follows

        //数据源
        public DataTable dataTable;
        public List<DataRow> dataRow = new List<DataRow>();
        private void CB_Click(object sender, RoutedEventArgs e)
        {
            if (DG.SelectedItem != null)
            {
                var row = DG.SelectedItem as DataRowView;
                dataRow.Add(row.Row);
            }
        }

Modify the DataGrid KeyUp events are as follows

private void DG_KeyUp(object sender, KeyEventArgs e)
        {
            if(e.Key==Key.Delete)
            {
                if (dataRow.Count> 0)
                {
                    for (var item = 0; item < dataRow.Count; item++)
                    {
                        dataTable.Rows.Remove(dataRow[item]);
               
                    }
                    dataRow.Clear();
                     
                } 
            }
