ComboBox SelectedItem display
The binding below gets and sets the selected item. It also displays items correctly, which in this case just means displaying a department's name.
However, instead of displaying the selected d开发者_如何学Pythonepartment name, it displays the selected department's ToString().
How can I fix this so the selected item displays only the department name?

Style="{StaticResource ComboBoxStyle}"
ItemContainerStyle="{StaticResource ComboBoxItemStyle}"
ItemsSource="{Binding Path=Departments}"
SelectedItem="{Binding Path=Department, Mode=TwoWay}"
IsSynchronizedWithCurrentItem="True"
DisplayMemberPath="Name"
/>
This is because .Net framework calls the ToString()
method on each observable collection item. To solve this problem you can override ToString()
method in your Model like this:
public override string ToString()
{
return this.Name;
}
I was able to fix the problem by changing the DisplayMemberPath to a DataTemplate as shown below.
Although I'm not sure why the DisplayMemberPath didn't work here, I have to assume there was some other bug in my code somewhere. Being an old question, the code has since changed and isn't worth recreating.
As an aside, I routinely use DataTemplates now, even for simple cases like this one.
