其他数据模板中的一个数据模板 [英] One Data Template inside Other data template

问题描述

参考以下主题，

https://social.msdn.microsoft.com/Forums / Silverlight的/ EN-US / bb1d29c9-b875-4bb7-8782-3f42a637c924 /动态决定 - 什么 - 用户控制 - 使用 - 一些模板功能于XAML添加论坛= WPF和放大器;教授为必填

我想进行重构作为一些控件（在上面例如。标签将重复所有模板）。我想为通用控件创建一个通用模板，为特定类型创建独特控件的单独数据模板。 

我尝试过以下代码， 

< ItemsControl.Resources> 
< DataTemplate DataType =" {x：Type local：Entry}"> 
< StackPanel Orientation =" Horizo​​ntal"高度= QUOT; 40"> 
< Label Content =" {Binding Text}"宽度= QUOT; 250"高度= QUOT; 25"余量= QUOT; 2英寸VerticalAlignment = QUOT;中心" /> 
< Button Content =" X"宽度= QUOT; 25"高度= QUOT; 25"余量= QUOT; 2英寸/> 
< Button Content =" Y"宽度= QUOT; 25"高度= QUOT; 25"余量= QUOT; 2英寸/> 
< / StackPanel> 
< / DataTemplate> 
< DataTemplate DataType =" {x：Type local：CheckBoxEntry}"> 
< StackPanel Orientation =" Horizo​​ntal"高度= QUOT; 40"> 
< CheckBox IsChecked =" {Binding IsChecked，Mode = TwoWay}"余量= QUOT; 2英寸VerticalAlignment = QUOT;中心" /> 
< / StackPanel> 
< / DataTemplate> 
< DataTemplate DataType =" {x：Type local：ComboBoxEntry}"> 
< StackPanel Orientation =" Horizo​​ntal"高度= QUOT; 40"> 
< ComboBox SelectedItem =" {Binding Text}"宽度= QUOT; 250"高度= QUOT; 25" 
 ItemsSource =" {Binding SelectionEntities}"余量= QUOT; 2英寸VerticalAlignment = QUOT;中心"> 
< i：Interaction.Triggers> 
< i：EventTrigger EventName =" DropDownOpened"> 
< i：InvokeCommandAction Command =" {Binding DOP}" /> 
< / i：EventTrigger> 
< i：EventTrigger EventName =" SelectionChanged"> 
< i：InvokeCommandAction Command =" {Binding DOP}" /> 
< / i：EventTrigger> 
< / i：Interaction.Triggers> 
< / ComboBox> 
< / StackPanel> 
< / DataTemplate> 
 
< /ItemsControl.Resources> 

但问题是，我无法看到为类型Entry定义的那些通用控件。

所以我想创建一个通用数据模板，我想拥有子模板。

这可能吗？！如果是这样，请告诉我如何。

问候，

也许你可以试试这个：

< ItemsControl.Resources> 
< DataTemplate x：Key =" BaseDataTemplate"> 
< StackPanel Orientation =" Horizo​​ntal"高度= QUOT; 40"> 
< Label Content =" {Binding Text}"宽度= QUOT; 250"高度= QUOT; 25"余量= QUOT; 2英寸VerticalAlignment = QUOT;中心" /> 
< Button Content =" X"宽度= QUOT; 25"高度= QUOT; 25"余量= QUOT; 2英寸/> 
< Button Content =" Y"宽度= QUOT; 25"高度= QUOT; 25"余量= QUOT; 2英寸/> 
< / StackPanel> 
< / DataTemplate> 
 
< DataTemplate DataType =" {x：Type local：Entry}"> 
< ContentPresenter Content =" {Binding}" ContentTemplate =" {StaticResource BaseDataTemplate}" /> 
< / DataTemplate> 
< DataTemplate DataType =" {x：Type local：CheckBoxEntry}"> 
< StackPanel Orientation =" Horizo​​ntal"高度= QUOT; 40"> 
< ContentPresenter Content =" {Binding}" ContentTemplate =" {StaticResource BaseDataTemplate}" /> 
< CheckBox IsChecked =" {Binding IsChecked，Mode = TwoWay}"余量= QUOT; 2英寸VerticalAlignment = QUOT;中心" /> 
<！ -  others  - > 
< / StackPanel> 
< / DataTemplate> 
 ..... 
< /ItemsControl.Resources> 

最好的问候，

Hi,

With reference to the below thread,

https://social.msdn.microsoft.com/Forums/silverlight/en-US/bb1d29c9-b875-4bb7-8782-3f42a637c924/dynamically-deciding-what-user-control-to-add-using-some-templates-in-xaml?forum=wpf&prof=required

I want to do refactoring as some of the controls(in the above eg. Label will get repeated for all template). I want to create one common template for generic controls and separate data template for unique controls for the particular type. 

I tried like the below code, 

<ItemsControl.Resources>
                        <DataTemplate DataType="{x:Type local:Entry}">
                            <StackPanel Orientation="Horizontal" Height="40">
                                <Label Content="{Binding Text}" Width="250" Height="25" Margin="2" VerticalAlignment="Center"/>
                                <Button Content="X" Width="25" Height="25" Margin="2"/>
                                <Button Content="Y" Width="25" Height="25" Margin="2"/>
                            </StackPanel>
                        </DataTemplate>
                        <DataTemplate DataType="{x:Type local:CheckBoxEntry}">
                            <StackPanel Orientation="Horizontal" Height="40">
                                <CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}" Margin="2" VerticalAlignment="Center"/>
                            </StackPanel>
                        </DataTemplate>
                        <DataTemplate DataType="{x:Type local:ComboBoxEntry}">
                            <StackPanel Orientation="Horizontal" Height="40">
                                <ComboBox SelectedItem="{Binding Text}" Width="250" Height="25" 
                                      ItemsSource="{Binding SelectionEntities}" Margin="2" VerticalAlignment="Center">
                                    <i:Interaction.Triggers>
                                        <i:EventTrigger EventName="DropDownOpened">
                                            <i:InvokeCommandAction Command="{Binding DOP}"/>
                                        </i:EventTrigger>
                                        <i:EventTrigger EventName="SelectionChanged">
                                            <i:InvokeCommandAction Command="{Binding DOP}"/>
                                        </i:EventTrigger>
                                    </i:Interaction.Triggers>
                                </ComboBox>
                            </StackPanel>
                        </DataTemplate>

                    </ItemsControl.Resources>

But problem with this is, i am not able to see those generic controls which is defined for type Entry.

So i want to create one generic data template within that i want to have child templates.

Can this possible?! if so please tell me how.

Sasikala

Hi,

Maybe you can try this:

   <ItemsControl.Resources>
                <DataTemplate x:Key="BaseDataTemplate">
                    <StackPanel Orientation="Horizontal" Height="40">
                        <Label Content="{Binding Text}" Width="250" Height="25" Margin="2" VerticalAlignment="Center"/>
                        <Button Content="X" Width="25" Height="25" Margin="2"/>
                        <Button Content="Y" Width="25" Height="25" Margin="2"/>
                    </StackPanel>
                </DataTemplate>
                
                <DataTemplate  DataType="{x:Type local:Entry}">
                    <ContentPresenter Content="{Binding}" ContentTemplate="{StaticResource BaseDataTemplate}"/>
                </DataTemplate>
                <DataTemplate DataType="{x:Type local:CheckBoxEntry}">
                    <StackPanel Orientation="Horizontal" Height="40">
                        <ContentPresenter Content="{Binding}" ContentTemplate="{StaticResource BaseDataTemplate}"/>
                        <CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}" Margin="2" VerticalAlignment="Center"/>
                        <!--others-->
                    </StackPanel>
                </DataTemplate>             
               .....
            </ItemsControl.Resources>
