获取WPF组合框选择的值 [英] Get wpf combobox selected value

问题描述

我如何获得所选择的值（如选项1 ）为字符串从下面我的例子。 。我试过的建议负荷在谷歌，但不能得到字符串

How do I get the selected value (eg Option1) as a string from my example below. I've tried loads of suggestions on Google but can't get the string.

XAML：

<ComboBox x:Name="selectOption" Text="Select Option" 
                 SelectionChanged="selectOption_SelectionChanged" 
                 SelectedValue="{Binding VMselectedOption, Mode=TwoWay}" >
    <ComboBoxItem Name="cbb1">Option1</ComboBoxItem>
    <ComboBoxItem Name="cbb2">Option2</ComboBoxItem>
    <ComboBoxItem Name="cbb3">Option3</ComboBoxItem>
</ComboBox>

代码隐藏：

private void selectOption_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
   var selectedValue = selectOption.SelectedValue; 
}

//elsewhere in code
var test = viewModel.VMselectedOption;

这两个了selectedValue和测试返回字符串 System.Windows.Controls.ComboBoxItem：选项而不是选项1

这应该是很简单的，但我不能得到这个工作，或看到有什么不好？

This should be really simple but I just cannot get this working or see what is wrong?

推荐答案

您不应手动插入组合框项目。通过使用 的ItemsSource 。

You shouldn't insert the combobox items manually. Set them by using ItemsSource.

基本上你应该创建的选项（或代表选择对象）列表，并将其设置为的ItemsSource ，这样一来你的的SelectedItem 将是到底哪个选择了该选项，而不是自动创建的包装 ComboboxItem

Basically you should create a list of options (or objects representing options) and set them as ItemsSource, this way your SelectedItem will be exactly the option which is selected, not the automatically created wrapping ComboboxItem.
