WPF DataGrid 之数据绑定--实例2

 

1.前台Grid定义

        <!--数据绑定-->
        <DataGrid Grid.Row="1"
                  Name="gridOne" Margin="10"
                  ColumnWidth="150"
                  AlternatingRowBackground="Linen"
                  AutoGenerateColumns="False"
                 >
            <DataGrid.Columns>
                <DataGridTextColumn Header="域名全称" Binding="{Binding HostName ,Mode=OneWay}"/>
                <DataGridTextColumn Header="IP地址" Binding="{Binding IP,Mode=OneWay}"></DataGridTextColumn>
                <DataGridCheckBoxColumn Header="是否启用" Binding="{Binding IsEnable,Mode=OneWay}" Width="80">
                </DataGridCheckBoxColumn>
                <DataGridTemplateColumn>
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <Button Content="删除" 
                                    Width="100" 
                                    Click="Button_Click_1" 
                                    Uid="{Binding IP ,Mode=OneWay}"
                                    ContentStringFormat="{Binding HostName,Mode=OneWay}">
                            </Button>

                            <!--Button 绑定显示内容-->
                            <!--<Button 
                                    Width="100" 
                                    Click="Button_Click_1">
                                <Button.Content>
                                    <TextBlock>
                                        <TextBlock.Text>
                                            <MultiBinding  StringFormat="{}{0}-{1}">
                                                <Binding Path="IP"/>
                                                <Binding Path="HostName"/>
                                            </MultiBinding>
                                        </TextBlock.Text>
                                    </TextBlock>
                                </Button.Content>
                            </Button>-->


                            <!--TextBox 绑定显示内容-->
                            <!--<TextBlock>
                                <TextBlock.Text>
                                    <MultiBinding  StringFormat="{}{0}-{1}">
                                        <Binding Path="IP"/>
                                        <Binding Path="HostName"/>
                                    </MultiBinding>
                                </TextBlock.Text>
                            </TextBlock>-->


                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>

2.后台代码处理

        HostsHelper _helper = new HostsHelper();
        public MainWindow()
        {
            InitializeComponent();
            //绑定列表
            Rebind();
        }
        //添加域名和IP绑定
        private void Button_Click(object sender, RoutedEventArgs e)
        {
            string ip = txtIp.Text;
            string hostname = txtHostName.Text;
            if (string.IsNullOrEmpty(hostname))
            {
                txtHostName.Focus();
                ShowResult("请输入域名");
                return;
            }
            if (string.IsNullOrEmpty(ip))
            {
                txtIp.Focus();
                ShowResult("请输入IP地址");
                return;
            }

            //添加结果
            _helper.Add(new HostData(true, ip, hostname));
            MessageBox.Show("添加成功");
            //重新绑定
            Rebind();
        }
        //重新绑定结果
        public void Rebind()
        {
            gridOne.ItemsSource = _helper.HostDatas;
            gridOne.Items.Refresh();
        }
        //显示结果
        public void ShowResult(string str)
        {
            Result.Content = str;
        }
        //删除内容
        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            Button btn = sender as Button;
            MessageBoxResult result = MessageBox.Show("确定要删除吗？", "提示", MessageBoxButton.YesNo);
            if (result == MessageBoxResult.Yes)
            {
                _helper.Remove(new HostData(true,btn.Uid.ToString(),btn.ContentStringFormat.ToString()));
                Rebind();
            }
        }
