WPF ComboBox 控件用法

1.引用基础类型填充下拉列表

• 引用命名空间：xmlns:sys="clr-namespace:System;assembly=mscorlib"

<ComboBox x:Name="ComboState" SelectedIndex="0" Height="28" SelectedValue="{Binding SelectedTarget,Mode=TwoWay}"  >
    <ComboBox.Items>
        <sys:String>expand</sys:String>
        <sys:String>iframe</sys:String>
        <sys:String>open</sys:String>
        <sys:String>href</sys:String>
        <sys:String>blank</sys:String>
    </ComboBox.Items>
</ComboBox>

2. 后台集合方式绑定下拉列表

<ComboBox x:Name="ComboState" ItemsSource="{Binding Targets}" DisplayMemberPath="Name" SelectedValuePath="Value" 
         SelectedIndex="0" Height="28" SelectedValue="{Binding SelectedTarget,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"  >
</ComboBox>
