我们可以在ViewModel中获取selecteditem吗？

Question

我有一个按钮的委托命令。我想在radgridview中选择一行，然后单击按钮以获取行信息。

观点：

 <telerik:RadGridView Name="playersGrid" 
                                 ItemsSource="{Binding Players}" 
                                 AutoGenerateColumns="False" SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
        <telerik:RadGridView.Columns>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Position}"/>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>
        </telerik:RadGridView.Columns>
    </telerik:RadGridView>

我的ViewModel是

private object selectedItem;

    public object SelectedItem
    {
        get { return this.selectedItem; }
        set
        {
            if (value != this.selectedItem)
            {
                this.selectedItem = value;
                this.OnPropertyChanged("SelectedItem");
            }
        }
    }

    protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)
    {
        PropertyChangedEventHandler handler = this.PropertyChanged;
        if (handler != null)
        {
            handler(this, args);
        }
    }

    private void OnPropertyChanged(string propertyName)
    {
        this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    }

    private void Click_CreateButton(object param)
    {
        // get row selectedItem
    }

有可能吗？
