[英]How to get property value from ComboBox?
How can I get property from this: 我如何从中获得财产:
<ComboBox x:Name="cmbCategory" Grid.Column="1" Grid.Row="5" HorizontalAlignment="Center" PlaceholderText="Categories">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock TextWrapping="Wrap" Width="100%" Text="{Binding name}" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Because this code below doesn't work, because I don't have 'Content' property, I have only 'name' property. 因为下面的代码不起作用,因为我没有'Content'属性,所以我只有'name'属性。 Then how can I get value from
name
property? 那么如何从
name
属性中获取价值?
string categories= (cmbCategory.Items[cmbCategory.SelectedIndex] as ComboBoxItem).Content.ToString();
I figured it out. 我想到了。
I used this: 我用过这个:
public object GetPropertyValue(object car, string propertyName)
{
return car.GetType().GetProperties()
.Single(pi => pi.Name == propertyName)
.GetValue(car, null);
}

Then I just use it like that: 然后我就这样使用它:
string categories= GetPropertyValue(cmbCategory.Items[cmbCategory.SelectedIndex], "name").ToString();
It works, thanks everyone for help. 它有效,谢谢大家的帮助。
