功能:通过响应UI Textbox 的值向ListView 绑定新添加的纪录。

UI XAML 代码

复制代码 代码如下:

<Grid Margin="5">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition/>
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition  Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <TextBlock  Grid.Row="0" Grid.Column="0" Text="商品名称" HorizontalAlignment="Right" VerticalAlignment="Center" />
            <TextBox Grid.Row="0" Grid.Column="1" Margin="2" VerticalAlignment="Center" Text="{Binding Path=ComName}" Name="tbkName"/>
            <TextBlock  Grid.Row="1" Grid.Column="0" Text="商品进货单价" HorizontalAlignment="Right" VerticalAlignment="Center" />
            <TextBox Grid.Row="1" Grid.Column="1" Margin="2" VerticalAlignment="Center" Text="{Binding Path=ComInPrice}" Name="tbkInPrice"/>
            <TextBlock  Grid.Row="2" Grid.Column="0" Text="商品零售价格" HorizontalAlignment="Right" VerticalAlignment="Center" />
            <TextBox Grid.Row="2" Grid.Column="1" Margin="2" VerticalAlignment="Center" Text="{Binding Path=ComOutPrice}" Name="tbkOutPrice"/>
            <TextBlock  Grid.Row="3" Grid.Column="0" Text="进货数量" HorizontalAlignment="Right" VerticalAlignment="Center" />
            <TextBox Grid.Row="3" Grid.Column="1" Margin="2" VerticalAlignment="Center" Text="{Binding Path=ComOutPrice}" Name="tbkComCount"/>

            <Button Grid.Row="4" Grid.Column="1" Content="添加新纪录" Margin="2" Padding="2" Name="btnAdd" Click="btnAdd_Click" />

            <TextBlock Grid.Row="5" Grid.ColumnSpan="2"  HorizontalAlignment="Stretch"  VerticalAlignment="Center"  Background="Black" />

            <ListView Name="lstDisplay" ItemsSource="{Binding}" Grid.Row="6" Grid.ColumnSpan="2">
                <ListView.View>
                    <GridView>
                        <GridView.Columns>
                            <GridViewColumn  Header="AutoID" DisplayMemberBinding="{Binding AutoID}"/>
                            <GridViewColumn Header="商品名称" DisplayMemberBinding="{Binding ComName}"/>
                            <GridViewColumn Header="进货价格" DisplayMemberBinding="{Binding Path=ComInPrice,StringFormat={}{0:c}}"/>
                            <GridViewColumn Header="零售价格" DisplayMemberBinding="{Binding Path=ComOutPrice,StringFormat={}{0:c}}"/>
                            <GridViewColumn Header="进货数量" DisplayMemberBinding="{Binding ComCount}"/>
                        </GridView.Columns>
                    </GridView>
                </ListView.View>
            </ListView>
        </Grid>

c#后代码

复制代码 代码如下:

DataTable Commodity = newTable();

        public MainWindow()
        {
            InitializeComponent();
            //DataTable Commodity = newTable();

        }

      

        private void btnAdd_Click(object sender, RoutedEventArgs e)
        {

            addNewMember(Commodity);
            lstDisplay.DataContext = Commodity;

        }

        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;
        }

        private  DataTable addNewMember(DataTable Table)
        {
           

            //inserting a new row in datatable Commodity;

            DataRow newRow = Table.NewRow();
            newRow["ComName"] = tbkName.Text;
            newRow["ComInPrice"] = tbkInPrice.Text;
            newRow["ComOutPrice"] = tbkOutPrice.Text;
            newRow["ComCount"] = tbkComCount.Text;
            Table.Rows.Add(newRow);
            return Table;
        }

 

        private static DataTable newTable()
        {
            //Create a new table named Commodity
            DataTable commodity = new DataTable("Commodity");


            //instert new columns
            DataColumn auto = new DataColumn("AutoID", typeof(Int32));
            //setting the column auto increment
            auto.AutoIncrement = true;
            commodity.Columns.Add(auto);
            commodity.Columns.Add("ComName", typeof(string));
            commodity.Columns.Add("ComInPrice", typeof(double));
            commodity.Columns.Add("ComOutPrice", typeof(double));
            commodity.Columns.Add("ComCount", typeof(System.Int32));
            commodity.PrimaryKey = new DataColumn[] { commodity.Columns[0] };
            return commodity;
        }
