如何从组合框获取文本c# Wpf
本文关键字:取文本 Wpf 获取 组合 | 更新日期: 2023-09-27 17:52:50
每当我试图从组合框中获取文本时它都会提取System.Windows.Controls.ComboBoxItem: Abc
我怎么能只得到"Abc"?我的意思是说仅值而不是整个堆栈跟踪。我的代码看起来像:-
XAML: -
<StackPanel Orientation="Horizontal" Width="auto" HorizontalAlignment="Center" Margin="0,10,0,0">
<TextBlock HorizontalAlignment="Left" FontFamily="/Vegomart;component/Images/#My type of font" Text="User Type:- " FontSize="18" Foreground="Black"/>
<ComboBox x:Name="userType" HorizontalAlignment="Right" FontFamily="/Vegomart;component/Images/#My type of font" Width="170" FontSize="18" Foreground="Black" Margin="40,0,0,0" >
<ComboBoxItem> Abc</ComboBoxItem>
</ComboBox>
</StackPanel>
c# : -
string value = userType.SelectedItem.ToString();
System.Diagnostics.Debug.WriteLine(value);
你的努力会很感激:).
谢谢,
<ComboBox x:Name="userType" SelectionChanged="userType_SelectionChanged">
<ComboBoxItem Content="Abc"/>
<ComboBoxItem>Bcd</ComboBoxItem>
</ComboBox>
后面的代码:
private void userType_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var comboBox = sender as ComboBox;
if (comboBox != null)
{
var comboBoxItem = comboBox.SelectedItem as ComboBoxItem;
if (comboBoxItem != null)
{
var content = comboBoxItem.Content;
System.Diagnostics.Debug.WriteLine(content);
}
}
}
<ComboBoxItem> Abc</ComboBoxItem>
将Content
设置为Abc
,因此您需要将SelectedItem
转换为ComboBoxItem
并获得该属性。
(XAML设置内容可以在基类ContentControl
中看到,ContentPropertyAttribute
定义了要设置的属性。)
这将返回组合框中所选项的文本。
string value = userType.Text.ToString();
您可以获取该项目的内容:
ComboBoxItem item = (ComboBoxItem)userType.SelectedItem;
string value = (string)item.Content;
System.Diagnostics.Debug.WriteLine(value);
