我建议将您的ComboBox移动到DataTemplate之外,并在ItemTemplate中进行ComboBox自定义。
<Window x:Class="BindXML.Views.MainView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Main Window" Height="400" Width="800">
<Window.Resources>
<DataTemplate x:Key="comboTemplate">
<TextBlock Text="{Binding [email protected]}" Width="70" />
</DataTemplate>
<XmlDataProvider x:Key="src" XPath="/Root">
<x:XData>
<Root xmlns="">
<Item ImageName="Image1.jpg" />
<Item ImageName="Image2.jpg" />
<Item ImageName="Image3.jpg" />
</Root>
</x:XData>
</XmlDataProvider>
</Window.Resources>
<DockPanel>
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<ComboBox x:Name="cboImages1"
Grid.Row="0"
DataContext="{StaticResource src}"
ItemTemplate="{StaticResource comboTemplate}"
ItemsSource="{Binding XPath=Item}"
SelectedItem="{Binding XPath=ImageName, Path=SelectedItem.Content, Mode=TwoWay}"
IsSynchronizedWithCurrentItem="True" >
</ComboBox>
<ComboBox x:Name="cboImages2"
Grid.Row="1"
DataContext="{StaticResource src}"
ItemTemplate="{StaticResource comboTemplate}"
ItemsSource="{Binding XPath=Item}"
SelectedItem="{Binding XPath=ImageName, Path=SelectedItem.Content, Mode=TwoWay}"
IsSynchronizedWithCurrentItem="True" >
</ComboBox>
<Button Grid.Row="2" Click="Button_Click" />
</Grid>
</DockPanel>
</Window>
下面的测试代码后表现出不同的ComboxBox所选项目:
private void Button_Click(object sender, RoutedEventArgs e)
{
XmlElement e1 = cboImages1.SelectedItem as XmlElement;
if (e1 != null)
{
XmlAttribute result1 = e1.Attributes["ImageName"] as XmlAttribute;
if (result1 != null)
{
string name1 = result1.Value;
}
}
XmlElement e2 = cboImages2.SelectedItem as XmlElement;
if (e2 != null)
{
XmlAttribute result2 = e2.Attributes["ImageName"] as XmlAttribute;
if (result2 != null)
{
string name2 = result2.Value;
}
}
}
什么上面的代码? – decyclone 2010-06-24 14:06:14
我的意思是xaml代码 – Jhelumi786 2010-06-24 14:18:38
好吧,我已经设法解决这个问题,但现在我有另一个。 我有三个组合框显示来自同一个源文件(xml)的图像。用户从每个组合框中挑选图像作为选择1,2 3. 我将这3个选择绑定到产品数据源(xml文件)中的三个不同字段,如Logo1,Logo2,Logo3),但所有三个comboboexs以某种方式被绑定一起。如果我从选区1中选取图像,则其他两个组合框将更新选区1。 – Jhelumi786 2010-06-24 15:48:39
