I use the following XAML to display a XamComboEditor-field in my XamDataGrid
<igDP:Field Name="NoteType" Label="Type" Width="70">
<igDP:Field.Settings>
<igDP:FieldSettings EditorType="{x:Type igEditors:XamComboEditor}">
<igDP:FieldSettings.EditorStyle>
<Style TargetType="{x:Type igEditors:XamComboEditor}">
<Setter Property="ItemsSource" Value="{Binding NoteTypes}" />
<Setter Property="DisplayMemberPath" Value="Name" />
</Style>
</igDP:FieldSettings.EditorStyle>
</igDP:FieldSettings>
</igDP:Field.Settings>
</igDP:Field>
Name="NoteType" refers to the key in the table/collection that contains the name that should be displayed
The column is displayed in the DataGrid, but the Name of the NoteType isn't displayd, only the key.
Am I missing something here?
HI,
I am attaching a sample application that embeds a XamComboEdtior into the XamDataGrid.

I am just following upu on this forum post.
Please let me know if you need further assistance regarding this issue.

Are you saying that the ComboBox has no dropdown data? Is it an empty dropdown?
If that is the case, it could be your ItemSource Bindng. In my sample I am binding.to a static resource.
Are you getting any bindng errors in the output window when you debug?
Sincerely,

It is also faced with similar problems ...The dropdown list shows a list of items, but when I select an item from the drop-down list, it is not updated in the field, and when I triggered the event DataGridRecordUpdating (object sender, RecordUpdatingEventArgs e)
var item = e.Record.DataItem;
var res = DoUpdate(ref item);
but the item.Manufacturer = null
The result is that I can not save changes to the database
My DataGrid xaml
<igDP:XamDataGrid HorizontalAlignment="Stretch" Name="xamDataGridAtmModels" VerticalAlignment="Stretch" Grid.Row="1" GroupByAreaLocation="None"
ActiveDataItem="{Binding Path=SelectedAtmModel, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
<igDP:XamDataGrid.FieldLayoutSettings>
<igDP:FieldLayoutSettings AutoGenerateFields="False"
AllowAddNew="True"
AddNewRecordLocation="OnBottom" />
</igDP:XamDataGrid.FieldLayoutSettings>
<igDP:XamDataGrid.FieldSettings>
<igDP:FieldSettings CellClickAction="SelectRecord"></igDP:FieldSettings>
</igDP:XamDataGrid.FieldSettings>
<igDP:XamDataGrid.FieldLayouts>
<igDP:FieldLayout>
<igDP:FieldLayout.Fields>
<igDP:UnboundField BindingPath="Manufacturer" BindingMode="TwoWay" Label="Производитель">
<igDP:UnboundField.Settings>
<Setter Property="ItemsSource" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.ManufacturersList}" />
<Setter Property="ValuePath" Value="Id"/>
</igDP:UnboundField.Settings>
</igDP:UnboundField>
</igDP:FieldLayout.Fields>
</igDP:FieldLayout>
</igDP:XamDataGrid.FieldLayouts>
</igDP:XamDataGrid>
as the DataSource I Use my ServerModeDataSource
<eid:ServerModeDataSource Name="AtmModelsDataSource"
EntityType="{Binding Path=EntityType, Mode=OneWay}"
DataGrid="{Binding ElementName=xamDataGridAtmModels, Path=.}"
SelectMethod="{Binding Path=SelectMethod, Mode=OneWay}"
UpdateMethod="{Binding Path=UpdateMethod, Mode=OneWay}"
DeleteMethod="{Binding Path=DeleteMethod, Mode=OneWay}"/>
In ViewModel:
public BindingList<IdNamePair<Guid>> ManufacturersList
public AtmModel SelectedAtmModel
{
get { return _selectedAtmModel; }
set
_selectedAtmModel = value;
RaisePropertyChangedEvent(() => SelectedAtmModel);
}
public class IdNamePair<T> : ValidatableUiFriendlyObject, IDataTransferObject
private T _id;
/// <summary>
/// Entity Id.
/// </summary>
[DataMember]
public T Id
get { return _id; }
_id = value;
RaisePropertyChangedEvent(() => Id);
internal Guid? VirtualId;
private string _name;
/// Entity name.
public virtual string Name
get { return _name; }
_name = value;
RaisePropertyChangedEvent(() => Name);
Please Help with this problem....
Please help, spent a second day on this issue, read the entire forum and the internet, and nothing found it.
I am attaching a new sample that binds the XamComboEdtior's ItemSource to the DataContent.
Plesase review my sample.
