news 来源：原创 2024/5/21 0:47:32

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>

<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
