少有人走的路

控件操作的反面例子如下：

数据和UI混在一起。i是数据，却和UI操作写成一堆。

 <ListBox x:Name="lbx1"/>

            for(int i=0;i<10;i++)
            {
                lbx1.Items.Add(new ListBoxItem()
                {
                    Content = new TextBlock()
                    {
                        Text = i.ToString()
                    }
                });
            }

实现数据驱动方式操作控件 

        <ListBox x:Name="lbx1">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <Border Width="10" Height="10" Background="{Binding colorName}"/>
                        <TextBlock Margin="10,0" Text="{Binding disName}"/>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
           
        </ListBox>

            var list1 = new List<MyColor>();
            list1.Add(new MyColor() { colorName = "#FF0000", disName = "Red" });
            list1.Add(new MyColor() { colorName = "#00FF00", disName = "Green" });
            list1.Add(new MyColor() { colorName = "#0000FF", disName = "Blue" });
            lbx1.ItemsSource = list1;

数据模板，表格控件的例子

                <DataGridTextColumn Binding="{Binding Name}"/>
                <DataGridTemplateColumn Header="操作">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel>
                                <Border Width="10" Height="10" Background="{Binding Code}"/>

                            </StackPanel>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>

上面例子如果想提供  添加，删除，复制按钮，只需要改下数据模板即可。

注意数据模板中只允许放一个元素，所以你得用容器放入多个元素。

  <DataTemplate>
                            <StackPanel>
                                <Border Width="10" Height="10" Background="{Binding Code}"/>
                                <TextBlock Margin="10,0" Text="{Binding Name}"/>
                                <Button Content="复制"/>
                                <Button Content="删除"/>
                                <Button Content="添加"/>
                            </StackPanel>
                        </DataTemplate>
