有个BingMap 自定义导航菜单问题，数据绑定问题

[iloveyoujia]

我在初始化BingMap之后，自定义了菜单功能，如下：
  public Top()
  {
    InitializeComponent();
     map.MapForeground.TemplateApplied += new EventHandler(MapForeground_TemplateApplied);
}



void MapForeground_TemplateApplied(object sender, EventArgs e)
        {
            map.MapForeground.NavigationBar.TemplateApplied += new EventHandler(NavigationBar_TemplateApplied);
        }
        void NavigationBar_TemplateApplied(object sender, EventArgs e)
        {
            NavigationBar navBar = map.MapForeground.NavigationBar;
            Button btnTest = new Button();
            btnTest.Content = "Click";
            navBar.HorizontalPanel.Children.Add(btnTest);
            if (navBar.HorizontalPanel != null)
            {
                navBar.HorizontalPanel.Children.Clear();
                CommandToggleButton btnCQ = new CommandToggleButton(new CustomCommand("城区"), "城区", "城区");
                navBar.HorizontalPanel.Children.Add(btnCQ);
}



public  class CustomCommand : NavigationBarCommandBase
    {
        public string CityName { get; set; }
        public CustomCommand(string name)
        {
            this.CityName = name;
        }
        public override void Execute(Microsoft.Maps.MapControl.Core.MapBase map)
        {
           
          
            double longitude = 0d;
            double latitude = 0d;

            switch (CityName)
            {
                case "城区":
                    longitude = double.Parse("29.35");
                    latitude = double.Parse("106.33");
                    map.ZoomLevel = 10;
                    DataBind(参数)    
---始终就无法绑定我的页面中的DataGrid了，因为它是当前页面的新类，基础类是 public partial class Top : UserControl
                    break;

            map.Center = new Location(longitude, latitude);

            NavigationBarCommandStatus status = this.GetStatus(map);

            if (status == NavigationBarCommandStatus.Checked)
                map.ScaleVisibility = Visibility.Collapsed;
            else if (status == NavigationBarCommandStatus.Normal)
                map.ScaleVisibility = Visibility.Visible;

        }

        public override NavigationBarCommandStatus GetStatus(MapBase map)
        {
            return base.GetStatus(map);
        }


    }

如何解决在同一个命令空间里，新类绑定基础类的控件呢?比如：DataGrid，我直接在基础类绑定是没有问题的。非常感谢。

不是很明白你的问题，什么叫做新类帮顶基础类的控件？能详细解释一下么？

[iloveyoujia]

其实就是 DataBind(参数) 在基础类里面有

PagedCollectionView pcv = new PagedCollectionView(Branchist);
this.dpBranchdataGrid.Source = pcv;
this.BranchdataGrid.ItemsSource = pcv;


我在新类里面调用不到这个办法。报不能使用static的方法错误。。。。

[kakaniuren]

在新类中做一个控件属性，通过赋值的方式将基础类中的控件给到新类，从而就可以实现在新类中进行绑定操作.

楼上的朋友，不好意思，我没看懂你的留言，看看能不能帮我改改。谢谢。
不知道哪儿有问题，没绑定成功数据。。
基础绑定数据没有问题，点菜单操作的时候绑定不上去。

更改如下2出：
1、----------------------------------------------------------------
DataPager dp=new DataPager();
DataGrid gd=new DataGrid();
if (navBar.HorizontalPanel != null)
{
navBar.HorizontalPanel.Children.Clear();
CommandToggleButton btnCQ = new CommandToggleButton(new CustomCommand("城区", dp, gd), "城区", "城区");
navBar.HorizontalPanel.Children.Add(btnCQ);
}

===>
navBar.HorizontalPanel.Children.Clear();
CommandToggleButton btnCQ = new CommandToggleButton(new CustomCommand("主城", dpBranchdataGrid, BranchdataGrid), "主城", "主城");
navBar.HorizontalPanel.Children.Add(btnCQ);
-------------------------------------------

2、
/*******************--此处绑定 Home() 中的 BindGrid(string regionname) 方法。*******************/
/*******************--此处绑定 Home() 中的 BindGrid(string regionname) 方法。*******************/
BindData(参数);



实现方法：
public void BindData(string CityName)
{

GetPivotViewer.GetDataPivotViewerSoapClient client = new GetPivotViewer.GetDataPivotViewerSoapClient();
client.GetBranchDataAsync(7, 0, CityName);
client.GetBranchDataCompleted +=
new EventHandler<GetPivotViewer.GetBranchDataCompletedEventArgs>(BranchData);
}


实现绑定
void BranchData(object sender, GetPivotViewer.GetBranchDataCompletedEventArgs e)
{
Random rd = new Random();
if (e.Error != null)
{ }
else
{
ObservableCollection<GetPivotViewer.BranchData> Branchist =
e.Result as ObservableCollection<GetPivotViewer.BranchData>;
string Region_Name = "";
List<string> valueList = new List<string>();
List<double> dboubleList = new List<double>();
for (int i = 0; i < Branchist.Count; i++)
{
Region_Name = Branchist[0].Region_Name.ToString();
GetPivotViewer.BranchData bd = Branchist[i];
valueList.Add(bd.Branch_Name);
dboubleList.Add(rd.Next(1435, 1883) / 10000.0 * 100);
}

//先绑定分页;
PagedCollectionView pcv = new PagedCollectionView(Branchist);
DP.Source = pcv;
DG.ItemsSource = pcv;

}
}
