ComboBox控件数据绑定

ComboBox控件在Silverlight3里和Silverlight4里的属性是不一样的，在Silverlight4里使用。

<UserControl xmlns:aui="clr-namespace:CRM.Class"

xmlns:my="clr-namespace:CRM.UserControls" > //添加用户控件的引用 和RowIndexConverter类的引用
    <UserControl.Resources>
        <aui:RowIndexConverter x:Key="RowIndex"></aui:RowIndexConverter>
    </UserControl.Resources>

<Grid x:Name="LayoutRoot" Background="#FFE8E8E8">

<ComboBox x:Name="combCardType"  Grid.Row="0" Grid.Column="1">
       <ComboBox.ItemTemplate>
            <DataTemplate>
                <StackPanel x:Name="myStackPanel" Orientation="Horizontal"  >
                     <TextBlock Name="lblCardTypeName" VerticalAlignment="Center" HorizontalAlignment="Center"
                                Text="{Binding Converter={StaticResource RowIndex}, ConverterParameter=CT_Name}" />
                     <TextBlock Name="lblCardTypeID" VerticalAlignment="Center" HorizontalAlignment="Center" 

                                Text="{Binding Converter={StaticResource RowIndex}, ConverterParameter=CT_ID}" />
                 </StackPanel>
             </DataTemplate>
        </ComboBox.ItemTemplate>
 </ComboBox>

<ComboBox x:Name="ComboNewsSortName" Style="{StaticResource ComboBoxStyle1}" ItemsSource="{Binding}" DisplayMemberPath="NewsSortName" SelectedValuePath="NewsSortID">
</ComboBox>

</Grid>

</UserControl>

Cs：

private ObservableCollection<Row> rowResult;

  #region 选出所有卡类型
        void CwIntegralCard_SelectCardTypeCompleted(object sender, SelectCardTypeCompletedEventArgs e)
        {
            combCardType.ItemsSource = null;
            rowResult = new ObservableCollection<Row>();
            Row LogRow = new Row();
            foreach (CardTypeDomain v in e.Result)
            {
                LogRow["CT_Name"] = v.CTName;
                LogRow["CT_ID"] = v.CTID;
                rowResult.Add(LogRow);
            }
            combCardType.ItemsSource = rowResult;            
        }
  #endregion

  #region 选出所有新闻类型

ComboNewsSortName.DataContext = e.Result;   //数据源绑定
int inewsSortID = Convert.ToInt32(newsInfoRow["NewsSortIDParamerter"]);
ComboNewsSortName.SelectedValue = inewsSortID; //取值
NewsDomain newsInfo = new NewsDomain();
newsInfo.NewsSortID =Convert.ToInt32(ComboNewsSortName.SelectedValue); //赋值

  #endregion
