填充DataGrid基于另一个数据网格的选定项目

Question

我有2个数据网格。应根据第一数据网格的选择，根据选择标准从数据库中提取数据。它需要填充第二个数据网格。

在wpf中做任何最好的方法吗？

这是我的xaml的代码：

<cmcCtl:CmcDataGrid x:Name="QueueSearchCampusGrid"
                                            Canvas.Left="0"
                                            Canvas.Top="0"
                                            Width="572"
                                            Height="114"
                                            HorizontalAlignment="Left"
                                            VerticalAlignment="Top"

                                  HorizontalAlignment="Left"
                                  VerticalAlignment="Top"
                                  Content=""
                                  Checked="CheckBoxHeadSelect_Checked"
                                  IsThreeState="False"
                                  Unchecked="CheckBoxHeadSelect_Unchecked" />
                    </Canvas>
                </Grid>

这是我的模型类的代码：

public ShoppingSheetQueueSearchClient SelectedValue
{
    get
    { 
        return _selectedValue; 
    }

    set
    {
        if (_selectedValue == value) return;
        _selectedValue = value;
        BindQueueSearchProgramVersionGridControl();
    }
}
