c#數據綁定之將datatabel的data添加listView中，扼要的經由過程代碼運用了DataTable，DataTableColumns,DataTableRow類，經由過程UI界面的Textbox向DataTable中添加數據然後呼應到ListView控件中。在本實例中重要針對若何刪除DataTable的記載，並同步到ListView中。

起首，對UI做一些修改，終究界面以下圖所示。重要是在ListView 中添加了CheckBox控件。

在ListView中添加CheckBox 的XAML 代碼：

<GridViewColumn x:Name="gvcSelectAll">
                                <GridViewColumn.Header>
                                    <CheckBox Content="全選" />
                                </GridViewColumn.Header>
                                <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox />
                                    </DataTemplate>
                                </GridViewColumn.CellTemplate>
                            </GridViewColumn>

在ListView中Items添加Button 的XAML 代碼：

<GridViewColumn Header="操作">
                                <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <Button Content="刪除" MinWidth="50" Margin="2" Name="btnDelete" Click="btnDelete_Click" CommandParameter="{Binding Path=AutoID}"/>
                                    </DataTemplate>
                                </GridViewColumn.CellTemplate>

其次，對Button添加

Click="btnDelete_Click"

事宜，事宜的呼應的C# 後台代碼為：

private void btnDelete_Click(object sender, RoutedEventArgs e)
        {
            Button b = sender as Button;
            Int32 AutoID = Convert.ToInt32(b.CommandParameter);
            delMember(Commodity, AutoID);
            lstDisplay.DataContext = Commodity;
            lstDisplay.Items.Refresh();

        }

        private DataTable delMember(DataTable Table,Int32 laction)
        {
            //Deleting  a existed row in datatable Commodity;
            DataRow delRow = Table.Rows.Find(laction);
            Table.Rows.Remove(delRow);
            return Table;
        }
