wpf的combobox和datagrid问题



如图。
怎么实现combobox 选项改变 datagrid也跟着改变？
[解决办法]
这个建议使用MVVM绑定，然后在Comobox的SelectedItem绑定的属性上的Set事件中

        <ComboBox SelectedItem="{Binding SelectedData}" ItemsSource="{Binding ComoboxData}"></ComboBox>
        <ListView ItemsSource="{Binding GridData}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="内设机构名称" DisplayMemberBinding="{Binding}"></GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

        public MainWindow()
        {
            InitializeComponent();
            this.DataContext = new MainWindowViewModel();
        }

//////////////////
public class MainWindowViewModel : INotifyPropertyChanged
        {
            private string _SelectedData;

            public string SelectedData
            {
                get { return _SelectedData; }
                set
                {
                    _SelectedData = value;
                    OnPropertyChanged("SelectedData");

                }
            }
            private ObservableCollection<string> _ComoboxSource;

            public ObservableCollection<string> ComoboxSource
            {
                get { return _ComoboxSource; }
                set
                {
                    _ComoboxSource = value;
                    OnPropertyChanged("ComoboxSource");
                }
            }

            private ObservableCollection<string> _GridData;
            /// <summary>
            /// GridData
            /// </summary>
            public ObservableCollection<string> GridData
            {
                get { return _GridData; }
                set
                {
                    _GridData = value;
                    OnPropertyChanged("GridData"); 
 
                }
            }

            private void RefreshGridData()
            {
                GridData.Clear();
                //GridData.Add();......
            }

            public event PropertyChangedEventHandler PropertyChanged;
            public void OnPropertyChanged(string name)
            {
                if (PropertyChanged != null)
                {
                    PropertyChanged(this, new PropertyChangedEventArgs(name));
                }
            }
        }

可以参照上面的，自己整理下吧，我是简单的写了下，有什么问题，可以再交流~
主要就是MVVM的使用
[解决办法]
那就new datagrid，设置 相关属性，然后stackpanel.children.add(新的grid)
