XamComboEditor displays value member unless it has the focus.
posted

I am creating the ComboBoxItemsProvider in XAML:

    <igDP:XamDataGrid.Resources>
        <igEditors:ComboBoxItemsProvider x:Key="PhoneTypes" />
    </igDP:XamDataGrid.Resources>

I am getting a reference to the items provider:

    ComboBoxItemsProvider ItemsProvider =
                      this.PhoneGrid.FindResource("PhoneTypes") as ComboBoxItemsProvider;

I am filling a ComboBoxItemsProvider with a sorted data view (from a data table):

    ItemsProvider.ItemsSource = dt.DefaultView;

I am setting the display and value paths:

    ItemsProvider.DisplayMemberPath = 'Name';
    ItemsProvider.ValuePath = 'PhoneTypeKey';

The problem is that the value (PhoneTypeKey) is being displayed instead of the Name field as designated by the DisplayMemberPath property. If I click into the cell, the value property is correctly replace (visually) by the display property. How do I get the DisplayMember to display when the cell does not have the focus?

Thx,
Tom

    I struggled with this issue several weeks back. I even contacted support. I can't remember the details, but I ended up with this:

    <igDP:Field Name="MultumRoute" Label="Route" >
        <igDP:Field.Settings>
            <igDP:FieldSettings EditAsType="{x:Type Domain:MultumRoute}" EditorType="{x:Type igDE:XamComboEditor}" >
                <igDP:FieldSettings.EditorStyle>
                    <Style TargetType="{x:Type igDE:XamComboEditor}">
                        <Setter Property="DisplayMemberPath" Value="Name" />
                        <Setter Property="ItemsSource" Value="{Binding Source={StaticResource multumRouteDropDownDataSource}, Mode=OneWay}"  />
                    </Style>
                </igDP:FieldSettings.EditorStyle>
            </igDP:FieldSettings>
        </igDP:Field.Settings>
    </igDP:Field>
