combo box in hierarchy xamWebGrid
posted

Hi,

I tried to bind data to a combo box located in a child column layout.  At first, the grdStart will be displayed to the users.  When the user clicks on one of the row,  GridOrd will show some records. I'm using XamWebView also.  Here is the code behind:

 .
 .
 .

 InitializeComponent();
 //Get data from WFC
 prxy.StartListCompleted += new EventHandler<StartListCompletedEventArgs>(prxy_StartListCompleted);
 prxy.StartListAsync();

        void prxy_StartListCompleted(object sender, StartListCompletedEventArgs e)
        {
            (this.FindName("grdStart") as XamWebGrid).ItemsSource = e.Result;
            (this.FindName("grdStart") as XamWebGrid).Visibility = Visibility.Visible;
        }

        private void grdStart_CellClicked(object sender, CellClickedEventArgs e)
        {

            prxy.GetHeaderCompleted += new EventHandler<GetHeaderCompletedEventArgs>     (prxy_GetHeaderCompleted);
            prxy.GetHeaderAsync();

 }


        void prxy_GetHeaderCompleted(object sender, GetHeaderCompletedEventArgs e)
        {
            (this.FindName("grdOrd") as XamWebGrid).ItemsSource = e.Result;
            (this.FindName("grdOrd") as XamWebGrid).Visibility = Visibility.Visible;

            //Combo Box data
            prxy.GetCagegoryCompleted += new EventHandler<GetCagegoryCompletedEventArgs>(prxy_GetCagegoryCompleted);
            prxy.GetCagegoryAsync();
        }

        void prxy_GetCagegoryCompleted(object sender, GetCagegoryCompletedEventArgs e)
        {

             I  cannot find the combo box to set the ItemsSource!!!
        }


     public class Category : EntityBase
     {
             public string Id { get; set; }
             public string Desc { get; set; }
     }

Here is Xaml code

    <Grid x:Name="LayoutRoot">
