【问题描述】：

公共类 DA_ActivityType 公共 int ID 获取；放; 公共字符串名称 获取；放;

public static List<DA_ActivityType> GetActivitytypes()

    DataContext dbo = new DataContext();
    IEnumerable<DA_ActivityType> activityTypes =
                     from actType in dbo.ActivityTypes
                     select new DA_ActivityType
                     
                         Id = actType.TypeId,
                         Name = actType.Name

                     ;

    return activityTypes.ToList();

//XAML 代码

<Grid>
    <Grid.Resources>
        <ObjectDataProvider x:Key="ActivityTypes" ObjectType="x:Type  c:ActivityType" MethodName="GetActivitytypes" />
    </Grid.Resources>
    <DataGrid AllowDrop="False" AutoGenerateColumns="False" HorizontalAlignment="Stretch" HorizontalContentAlignment="Left" Margin="1,2,-1,-2" Name="DefineManulaColumns" SelectionMode="Single" VerticalAlignment="Stretch">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="Binding ActivityName" Header="Activity" />

            <DataGridTextColumn Binding="Binding EndTime" Header="End" />
            <DataGridCheckBoxColumn Binding="Binding Path=Archived" Header="Archived"/>
            <DataGridTemplateColumn Header="Type">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="Binding ActivityName" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
                <DataGridTemplateColumn.CellEditingTemplate>
                    <DataTemplate>
                        <ComboBox SelectedItem="Binding ActivityName" DisplayMemberPath="Binding Name"  ItemsSource="Binding Source=StaticResource ActivityTypes" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellEditingTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
        <DataGrid.AlternatingRowBackground>
            <LinearGradientBrush EndPoint="1,0.5" StartPoint="0,0.5">
                <GradientStop Color="#FFC4DCFF" Offset="0" />
                <GradientStop Color="#FFEFF4F8" Offset="1" />
                <GradientStop Color="#FF79B7F8" Offset="0.558" />
            </LinearGradientBrush>
        </DataGrid.AlternatingRowBackground>
    </DataGrid>
</Grid>

【问题讨论】：

您是在问如何将此列表绑定到数据网格中存在的组合框？

【参考方案1】：

要么：

<ComboBox x:Name="myCombo" />
myCombo.ItemsSource = GetMyCollection();

或：

<ComboBox ItemsSource="Binding" />
and one of the parent elements must have the DataContext = GetMyCollection();
