ComboBox KeyValuePair Binding WPF - Display Member

i got a quick question about binding the DisplayMember of my ComboBox. I have a list with a KeyValuePair for example:

1, Value1;
2, Value2;
3, Value3;

My SelectedValuePath is set to Key which is in my example "1". Now i want my DisplayMemberPath to show "Key - Value" so for example the Textbox should show "1 - Value1". Is that possible? Thank's in advance!

Solution

  • If your ComboBox is not editable, you can create a DataTemplate for your key-value pairs.

    <ComboBox ...>
   <ComboBox.ItemTemplate>
      <DataTemplate>
         <TextBlock>
            <Run Text="{Binding Key, Mode=OneWay}"/>
            <Run Text=" - "/>
            <Run Text="{Binding Value, Mode=OneWay}"/>
         </TextBlock>
      </DataTemplate>
   </ComboBox.ItemTemplate>
</ComboBox>
