c#数据绑定之删除datatable数据示例

c#数据绑定之将datatabel的data添加listView中，简要的通过代码应用了DataTable，DataTableColumns,DataTableRow类，通过UI界面的Textbox向DataTable中添加数据然后响应到ListView控件中。在本实例中主要针对如何删除DataTable的纪录，并同步到ListView中。

首先，对UI做一些改动，最终界面如下图所示。主要是在ListView 中添加了CheckBox控件。

在ListView中添加CheckBox 的XAML 代码：

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

在ListView中Items添加Button 的XAML 代码：

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

其次，对Button添加

Click="btnDelete_Click"

事件，事件的响应的C# 后台代码为：

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;
        }
