我有一个DataGridTemplateColumn：

<DataGridTemplateColumn CellStyle="{x:Null}" Width="85" Header="{Extentions:DisplayName Type=Type:StandardClass, PropertyName=ProductKind}">
                    <DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate>
                            <ComboBox ItemsSource="{Binding ElementName=viewSourceDataGrid, Path=DataContext.ProductKindCollection}" 
                                      DisplayMemberPath="Title" Style="{x:Null}"
                                      SelectedValue="{Binding ProductKind, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}" />

                        </DataTemplate>

                    </DataGridTemplateColumn.CellEditingTemplate>

                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock
                                      Text="{Binding ProductKind.Title, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}" />

                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>

                </DataGridTemplateColumn>

并且还尝试了：

<DataGridComboBoxColumn Header="{Extentions:DisplayName Type=Type:StandardClass, PropertyName=ProductKind}"
                    DisplayMemberPath="Title"
                                    SelectedItemBinding="{Binding ProductKindID, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, NotifyOnValidationError=True,ValidatesOnDataErrors=True}">
                    <DataGridComboBoxColumn.ElementStyle>
                        <Style TargetType="{x:Type ComboBox}" BasedOn="{StaticResource EditBaseStyle}">
                            <Setter Property="ItemsSource" Value="{Binding ElementName=viewSourceDataGrid, Path=DataContext.ProductKindCollection}" />
                        </Style>
                    </DataGridComboBoxColumn.ElementStyle>
                    <DataGridComboBoxColumn.EditingElementStyle>
                        <Style TargetType="{x:Type ComboBox}" BasedOn="{StaticResource EditBaseStyle}">
                            <Setter Property="ItemsSource" Value="{Binding ElementName=viewSourceDataGrid, Path=DataContext.ProductKindCollection}" />
                        </Style>
                    </DataGridComboBoxColumn.EditingElementStyle>
                </DataGridComboBoxColumn>

在win 7上一切正常，但在win Server 2008和2003上对其进行了测试，结果：

DataGridComboBoxColumn

我删除风格细胞和DataGrid但仍（正如你看到的）ComboBox项目不出现

最终经过测试，RelativeSource而不是ElementName。

经过一天的时间浪费，效果很好Win Server！

解决方案！！：

<DataGridTemplateColumn CellStyle="{x:Null}" Width="85" Header="{Extentions:DisplayName Type=Type:StandardClass, PropertyName=ProductKind}">
                    <DataGridTemplateColumn.CellEditingTemplate>
                        <DataTemplate>
                            <ComboBox 
                                ItemsSource="{Binding Path=DataContext.ProductKindCollection,RelativeSource={RelativeSource AncestorType=DataGrid}}"
                                      DisplayMemberPath="Title" Style="{x:Null}"
                                      SelectedValue="{Binding ProductKind, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}" />

                        </DataTemplate>

                    </DataGridTemplateColumn.CellEditingTemplate>

                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock
                                      Text="{Binding ProductKind.Title, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, UpdateSourceTrigger=PropertyChanged}" />

                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>

                </DataGridTemplateColumn>
