Hi,
I am createing WAP Browser Application to use RadCarousel, in which I am binding data to RadCarousel with datatable. When I run this xbap it doesnt show any error. but not showing data in CaruselItems.
can you please tell me what I am missing here?

and my datatable is like


public DataTable getData()

            dt.Columns.Add("LastName", Type.GetType("System.String"));
            dt.Columns.Add("Phone", Type.GetType("System.String"));
            dt.Columns.Add("Picture");
            
            try
            {
                DataRow dr = dt.NewRow();
                dr["ID"] = 46;
                dr["FirstName"] = "Ana";
                dr["LastName"] = "Trujillo";
                dr["Phone"] = "6562-9722";
                dr["Picture"] = pic code here
                dt.Rows.Add(dr);
                dt.AcceptChanges();
                dr = dt.NewRow();
                dr["ID"] = 47;
                dr["FirstName"] = "Ana";
                dr["LastName"] = "Trujillo";
                dr["Phone"] = "6562-9722";
               dr["Picture"] = pic code here
                dt.Rows.Add(dr);
                dt.AcceptChanges();
            }
            catch(Exception ex)
            {

            }

            return dt;
        }

Hi Vandana,

The problem is that the binding "{Binding Path=Data.FirstName}" is incorrect. There is no property FirstName on the data items that your are binding to. Since you are binding to DataRows you need to change the binding to "{Binding Path=Data[FirstName]}" .
Now your carrousel items should display the data correctly.

Hi Milan,

After giving {Binding Path=Data.FirstName} it is working for FirstName and Phone. But it does not display Image in the rectangle (second row)
My code in xaml is like:

<Rectangle Grid.Row="1" RadiusX="3" RadiusY="3" Width="110" Height="80">
                                    <Rectangle.Fill>
                                        <ImageBrush x:Name="brush" ImageSource="{Binding Path=Data[Picture]}"/>
                                    </Rectangle.Fill>
</Rectangle>

I have created new column in dtatable like:
dt.Columns.Add("Picture", typeof(BitmapImage));

and added picture like:
dr["Picture"] = new BitmapImage(new Uri("sky.png", UriKind.RelativeOrAbsolute));
It gives runtime error

And when I use Code for picture
dr["Picture"] =  code here
Is there no compilation error but image is not displyed in carousel item. Can you please tell me where I am wrong?

Thanx and Regards
Vandana
