Question

尝试找到一种方法来处理DataGrid的两个ObservableCollections。一个ObservableCollection应该包含DataGrids的集合，另一个是DataGrid的Rows集合。在按钮上我添加了包含TextBoxes和DataGrid的Tabs。我直接在DataGrid中输入数据。在添加新选项卡时，我想在此选项卡中保存数据网格，并希望在新选项卡上有新的（没有数据）DataGrid，当我更改选项卡时，我想在每个具体的选项卡DataGrid中看到我输入的数据。这有可能吗？

ObservableCollection<DataGridsOBC>[0]
DataGrid 1
+---------------------------------------------+
+        |  Column 1  |  Column 2 |  Column 3 |
+        |  bind to   |  bind to  |  bind to  |
+        |  Property 1| Property 2| Property 3|
+---------------------------------------------|
           ObservableCollection<RowsOBC>
+ Row 0  | ObservableCollection<RowsOBC>[0]   |
+ Row 1  | ObservableCollection<RowsOBC>[1]   |
+ Row 2  | ObservableCollection<RowsOBC>[2]   |
+  ...   | ObservableCollection<RowsOBC>[...] |
+---------------------------------------------+
ObservableCollection<DataGridsOBC>[1]
DataGrid 2
+---------------------------------------------+
+        |  Column 1  |  Column 2 |  Column 3 |
+        |  bind to   |  bind to  |  bind to  |
+        |  Property 1| Property 2| Property 3|
+---------------------------------------------|
           ObservableCollection<RowsOBC>
+ Row 0  | ObservableCollection<RowsOBC>[0]   |
+ Row 1  | ObservableCollection<RowsOBC>[1]   |
+ Row 2  | ObservableCollection<RowsOBC>[2]   |
+  ...   | ObservableCollection<RowsOBC>[...] |
+---------------------------------------------+

如果它的可能性，它应该如何在xaml中看？

        <DataGrid ItemsSource="{Binding }">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Column 1" Binding="{Binding Property 1, Mode=TwoWay}"/>
                <DataGridTextColumn Header="Column 2" Binding="{Binding Property 2, Mode=TwoWay}"/>
                <DataGridTextColumn Header="Column 3" Binding="{Binding Property 3, Mode=TwoWay}"/>
                </DataGrid.Columns>
            </DataGrid

在代码背后？

 public class DataGridsOBCViewModel : ViewModelBase 
{
    public ObservableCollection<RowsOBC> _Rows;
    public ObservableCollection<RowsOBC> Rows
    {
        get { return _Rows != null ? _Rows : _Rows = new ObservableCollection<RowsOBC>(); }
        set { _Rows = value; OnPropChange("Rows"); }
    }

public DataGridsOBCViewModel()
    {

    }

}

public class RowsOBC : ViewModelBase
{
    public ObservableCollection<Properties> _Items;
    public ObservableCollection<Properties> Items
    {
        get { return _Items != null ? _Properties : _Items = new ObservableCollection<Properties>(); }
        set { _Items = value; OnPropChange("Properties"); }
    }
}

public class Properties: ViewModelBase
{
    private string _Property1;
    private string _Property2;
    private string _Property3;

    public string Property1
    {
        get { return _Property1; }
        set { if (_Property1 != value) { _Property1 = value; OnPropChange("Property1"); } }
    }

    //............... etc
}

DataGrid的两个ObservableCollections可能吗？一个用于行，第二个用于DataGrid
