Xaml ListView根据另一列的数据设置列数据模板（celltemplateselector）

我有一个列表视图，您可以在下面的代码中看到：

<ListView Grid.Row="2" MinHeight="75" x:Name="_lstvSearch" ItemsSource="{Binding Search.SearchExpressions}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Field name">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <ComboBox IsEditable="True" ItemsSource="{Binding DataContext.Fields, 
                                   RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}}"
                                          SelectedItem="{Binding Field, Mode=TwoWay}"
                                          DisplayMemberPath="Field.UserFriendlyFieldName"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="Operator">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <ComboBox IsEditable="True" ItemsSource="{Binding Field.Operators}"
                                          SelectedItem="{Binding Operator, Mode=TwoWay}"
                                          DisplayMemberPath="Operator"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="Value">
                        <GridViewColumn.CellTemplateSelector>
                            <vm:FieldValueTemplateSelector>
                                <vm:FieldValueTemplateSelector.Alpha>
                                    <DataTemplate>
                                        <TextBox Text="{Binding Value}"/>
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.Alpha>
                                <vm:FieldValueTemplateSelector.Numeric>
                                    <DataTemplate>
                                        <igEditors:XamNumericEditor Value="{Binding Value}" />
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.Numeric>
                                <vm:FieldValueTemplateSelector.CheckBox>
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding Value}"/>
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.CheckBox>
                                <vm:FieldValueTemplateSelector.DateTime>
                                    <DataTemplate>
                                        <igEditors:XamDateTimeEditor Value="{Binding Value}" />
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.DateTime>
                                <vm:FieldValueTemplateSelector.DropDownItem>
                                    <DataTemplate>
                                        <ComboBox ItemsSource="{Binding Value}"/>
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.DropDownItem>
                                <vm:FieldValueTemplateSelector.Generic>
                                    <DataTemplate>
                                        <TextBox Text="{Binding Value}"/>
                                    </DataTemplate>
                                </vm:FieldValueTemplateSelector.Generic>
                            </vm:FieldValueTemplateSelector>
                        </GridViewColumn.CellTemplateSelector>
                    </GridViewColumn>
                    <GridViewColumn Header="AND/OR">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <ComboBox IsEditable="True" ItemsSource="{Binding DataContext.ConditionLinks, 
                                    RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}}"
                                          SelectedItem="{Binding BooleanOperator, Mode=TwoWay}"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="Remove">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Button Content="Remove" IsEnabled="{Binding IsValid}" Tag="{Binding}" Click="Button_Click"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

我的问题是，我不希望CellTemplate根据第一列字段名的选择来更改值列，但我如何触发它

---

当选择该字段时，我的model cald FieldDatatype中有一个属性，我根据该属性确定在第一列中选择的字段类型。正如您在Value列中所看到的，我设置了一个CellTemplateSelector（FieldValueTemplateSelector），但是这个集合只在datatemplate中存在一次，当我从第一列中选择其他字段时不会刷新。
