two filed in a wpf comboBox

I fill my ComboBox like this

            using (MorEntities1 c = new MorEntities1())
        {
            var myViewSource = new CollectionViewSource { Source = c.People.ToList() };
            myViewSource.SortDescriptions.Add(
              new SortDescription("Family_Name", ListSortDirection.Ascending)
            );
            CB_Coehn.ItemsSource = myViewSource.View;
            CB_Coehn.DisplayMemberPath = "Family_Name";
            CB_Coehn.SelectedValuePath = "Person_Id";
            CB_Coehn.SelectedIndex = 0;
       }

But in the database I have a field First Name and field Last Name , How can I view the two fields in the ComboBox (LastName , FirstName) ?

This is in WPF and c#

Thanks in advance for help

If you have control over the "People" class, you could create a new property called "DisplayName" that formats it the way you want and set your DisplayMemberPath to that property:

public string DisplayName
{
    get { return string.format("{0}, {1}", LastName, FirstName); }
}

CB_Coehn.DisplayMemberPath = "DisplayName";

If you can do all of this in XAML instead of the code-behind, you can do it like this:

<ComboBox x:Name="CB_Coehn">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <TextBlock>
                    <TextBlock.Text>
                        <MultiBinding StringFormat="{0}, {1}">
                            <Binding Path="LastName" />
                            <Binding Path="FirstName" />
                        </MultiBinding>
                    </TextBlock.Text>
                </TextBlock>
            </Grid>
        </DataTemplate>
    </ComboBox.ItemTemplate>

Note: I have NOT tested this code, only going by memory, but it should be at least very close.

You need to create an itemscontrol itemtemplate which contains two labels and then bind their Text properties to the item.firstName and item.lastName.

See here for an example.
