换整个Template和换Template里某个属性（项目）

Bool？属性切换不同控件

方法1：换整个某个Custom的control的整个Template可以用DataTemplate的DataTrigger，用在collection里（ListView/DataGrid），特点是在Template外面，换Template


例子：主要是换自定义的<Control>，用<DataTemplate.Triggers>换在DT里<Control>的Template

View Code 
<DataTemplate x:Key="SensorCheckRow_DataTemplate">
    <Control x:Name="SwitchControl">
      <Control.Template>
        <ControlTemplate TargetType="{x:Type Control}">
          <Rectangle HorizontalAlignment="Center" VerticalAlignment="Center"
                     Width="23"
                     Height="23"                        
                     Fill="{StaticResource Icon_Hover_Job}" />
        </ControlTemplate>
                
      </Control.Template>
    </Control>
    <DataTemplate.Triggers>
      <DataTrigger Binding="{Binding Path=IsSensorCheckPassed}" Value="True">
        <Setter TargetName="SwitchControl" Property="Template" Value="{StaticResource TickIcon_ControlTemplate}"/>
      </DataTrigger>
      <DataTrigger Binding="{Binding Path=IsSensorCheckPassed}" Value="False">
        <Setter TargetName="SwitchControl" Property="Template" Value="{StaticResource ErrorIcon_ControlTemplate}"/>
      </DataTrigger>
      <DataTrigger Binding="{Binding Path=IsSensorCheckPassed}" Value="{x:Null}">
        <Setter TargetName="SwitchControl" Property="Template" Value="{StaticResource Empty_ControlTemplate}"/>
      </DataTrigger>
    </DataTemplate.Triggers>
  </DataTemplate>

其各种模板的定义：注意x:Type要和上面DT里要换Template的Control类型一致

View Code 
 1 <ControlTemplate x:Key="Empty_ControlTemplate" TargetType="{x:Type Control}">
 2     <Grid/>
 3   </ControlTemplate>
 4   
 5   <ControlTemplate x:Key="ErrorIcon_ControlTemplate" TargetType="{x:Type Control}">
 6     <Rectangle HorizontalAlignment="Center" VerticalAlignment="Center"
 7                Width="23"
 8                Height="23"                        
 9                Fill="{StaticResource Icon_CrossForDataGrid}" />
10   </ControlTemplate>
11   
12   <ControlTemplate x:Key="TickIcon_ControlTemplate" TargetType="{x:Type Control}">
13     <Rectangle HorizontalAlignment="Center" VerticalAlignment="Center"
14                Width="23"
15                Height="23"                        
16                Fill="{StaticResource Icon_TickForDataGrid}" />
17   </ControlTemplate>
18   
19   <ControlTemplate x:Key="ProgramButton_ControlTemplate" TargetType="{x:Type Control}">
20             <Grid HorizontalAlignment="Center" VerticalAlignment="Center">
21               <Button Width="76"
22                             Height="26"
23                             FontSize="10pt"
24                             Command="{Binding Path=DataContext.ProgramToolCommand,RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}"
25                             CommandParameter="{Binding ToolName}"
26                             Content="Program"
27                             Style="{StaticResource General_Button_Style}" 
28                             BorderBrush="#FF2F2F2F"/> 
29           </Grid>
30  </ControlTemplate>

这样调用：

1  <DataGridTemplateColumn 
2               Width="*"
3               IsReadOnly="True" 
4               HeaderTemplate="{StaticResource SensorCheckHeader_DataTemplate}"
5               CellTemplate="{StaticResource SensorCheckRow_DataTemplate}"/>
View Code

 

方法2：把不同状态下的Contorl叠在一起写在一个不带x:Type的ControlTemplate里（即不是通用应用这个模板，而是通过Key来匹配），ControlTemplate的每一个子Tag都可以用x：Name在trigger中再定位，用ControlTemplate的DataTrigeer来切换各个control的Visibility。

View Code 
 1 <ControlTemplate x:Key="LoadingSpinner_ControlTemplate" >
 2               <Grid>
 3                <StackPanel x:Name="LoadingState" Orientation="Vertical">
 4                     <localUserControl:CircleLoadingAnimation  RenderTransformOrigin="0.5,0.5" 
 5                                                               Width="303.868" 
 6                                                               Height="150" 
 7                                                               Margin="0,-20,0,0">
 8                        <localUserControl:CircleLoadingAnimation.RenderTransform >
 9                            <TransformGroup>
10                                <ScaleTransform ScaleX="0.2" ScaleY="0.2"/>
11                            </TransformGroup>
12                        </localUserControl:CircleLoadingAnimation.RenderTransform>
13                    </localUserControl:CircleLoadingAnimation>
14                     <TextBlock TextWrapping="Wrap" Text="Starting Electro-Hydraulic Lock Check" Style="{DynamicResource Univers55_TextBlock_Style}" Margin="300,-95,300,0" />
15                 </StackPanel>
16                 
17                 <StackPanel x:Name="PassState" Orientation="Vertical" >
18                 <ContentControl x:Name="LoadingSpinnerPass"
19                                 Style="{StaticResource loadingSpinnerControlStyle}" 
20                                 RenderTransformOrigin="0.5,0.5" 
21                                                               Width="303.868" 
22                                                               Height="150" 
23                                                               Margin="0,30,0,0">
24                     <ContentControl.RenderTransform>
25                         <TransformGroup>
26                             <ScaleTransform ScaleX="0.2" ScaleY="0.2"/>
27                         </TransformGroup>
28                     </ContentControl.RenderTransform>
29                 </ContentControl>
30                 <TextBlock TextWrapping="Wrap" Text="Check Passed" Style="{DynamicResource Univers55_TextBlock_Style}" Margin="300,0"/>
31             </StackPanel>
32             
33                 <StackPanel x:Name="FailState" Orientation="Vertical" >
34                     <ContentControl 
35                                     x:Name="LoadingSpinnerFail"
36                                     Style="{StaticResource loadingSpinnerControlStyle}" 
37                                     RenderTransformOrigin="0.5,0.5" 
38                                     Width="303.868" 
39                                     Height="150" 
40                                     Margin="0,30,0,0">
41                         <ContentControl.RenderTransform>
42                             <TransformGroup>
43                                 <ScaleTransform ScaleX="0.2" ScaleY="0.2"/>
44                             </TransformGroup>
45                         </ContentControl.RenderTransform>
46                     </ContentControl>
47                     <TextBlock TextWrapping="Wrap" Text="Check Failed" Style="{DynamicResource Univers55_TextBlock_Style}" Margin="300,0"/>
48                 </StackPanel>
49             </Grid>
50                 <ControlTemplate.Triggers>
51                   <DataTrigger Binding="{Binding IsLockCheckStatus}" Value="{x:Null}">
52                     <Setter TargetName="LoadingState" Property="Visibility" Value="Visible"/>
53                     <Setter TargetName="PassState" Property="Visibility" Value="Collapsed"/>
54                     <Setter TargetName="FailState" Property="Visibility" Value="Collapsed"/>
55                   </DataTrigger>
56                   <DataTrigger Binding="{Binding IsLockCheckStatus}" Value="True">
57                     <Setter TargetName="PassState" Property="Visibility" Value="Visible"/>
58                     <Setter TargetName="LoadingState" Property="Visibility" Value="Collapsed"/>
59                     <Setter TargetName="FailState" Property="Visibility" Value="Collapsed"/>
60                   </DataTrigger>
61                   <DataTrigger Binding="{Binding IsLockCheckStatus}" Value="False">
62                     <Setter TargetName="FailState" Property="Visibility" Value="Visible"/>
63                     <Setter TargetName="LoadingState" Property="Visibility" Value="Collapsed"/>
64                     <Setter TargetName="PassState" Property="Visibility" Value="Collapsed"/>
65                   </DataTrigger>
66                 </ControlTemplate.Triggers>
67               </ControlTemplate>

 

注意：ControlTemplate的DataTrigger最常用的还是Change模板里某一个元素的属性

换ControlTemplate里某个元素的属性：一般用在同一个custom contro的某个元素的属性的改变，比变换button的commandparameter，content

用在单个控件，特点是在Template里面，换Template里面的设置

View Code 
  <Style x:Key="AddToolOrUpdateToggleButton" TargetType="{x:Type ToggleButton}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ToggleButton}" >
                        <Button x:Name="AddToolOrUpdateButton"
                                Width="110"
                                Height="36"
                                HorizontalAlignment="Right"
                                Command="{Binding AddUpdateToolCommand}"
                                KeyboardNavigation.TabIndex="4"
                                Style="{StaticResource General_Button_Style}" 
                                BorderBrush="#FF2F2F2F" />
                        <ControlTemplate.Triggers>
                            <DataTrigger Binding="{Binding IsAddTool}" Value="True">
                                <Setter TargetName="AddToolOrUpdateButton" Property="Content" Value="Add Tool" />
                                <Setter TargetName="AddToolOrUpdateButton" Property="CommandParameter" Value="AddTool" />
                            </DataTrigger>
                            <DataTrigger Binding="{Binding IsAddTool}" Value="False">
                                <Setter TargetName="AddToolOrUpdateButton" Property="Content" Value="Update" />
                                <Setter TargetName="AddToolOrUpdateButton" Property="CommandParameter" Value="UpdateTool" />
                            </DataTrigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

 

方法3：ContentControl当作一个custom control，内部切换ContentTemplate

利用了<ContentControl>可以是任何control的基类，创建我们自己的<ContentControl>与后台的VM下的Bool？bind在一起，切换<ContentControl>的ContentTemplate属性DataTemplate类型的

首先Resource中定义三种DT资源（注意一定要写DataType="{x:Type vmodel:ProgramResultViewModel}）。

x:Key="ProgramStatus_EqualTrue_View"

 1 <DataTemplate x:Key="ProgramStatus_EqualTrue_View" DataType="{x:Type vmodel:ProgramResultViewModel}">
 2         <StackPanel x:Name="ProgramPassedPanel" Orientation="Vertical">
 3           <TextBlock Style="{DynamicResource Univers65_TextBlock_Style}" Margin="0,20,0,0"><Run Text="This tool has been"/><LineBreak/><Run Text="successfully programmed."/></TextBlock>
 4 
 5           <Grid KeyboardNavigation.TabNavigation="None" 
 6                 Margin="0,20,0,0" 
 7                 HorizontalAlignment="Center" 
 8                 VerticalAlignment="Center">
 9             <Grid.ColumnDefinitions>
10               <ColumnDefinition Width="*" />
11               <ColumnDefinition Width="Auto" />
12             </Grid.ColumnDefinitions>
13             <Grid.RowDefinitions>
14               <RowDefinition Height="*" />
15               <RowDefinition Height="*" />
16               <RowDefinition Height="*" />
17               <RowDefinition Height="*" />
18               <RowDefinition Height="*" />
19             </Grid.RowDefinitions>
20 
21 
22             <TextBlock FontSize="16pt" Margin="0,2" Foreground="#FF414142"
23                        Style="{StaticResource Univers55_TextBlock_Style}" 
24                        Text="Serial Number"  VerticalAlignment="Center" HorizontalAlignment="Left" />
25             <TextBlock  Grid.Column="1"
26                         HorizontalAlignment="Left"

DT资源里的view tree下会bind到VM里的属性，由于是DP所以会自己向下寻找，但是Button的Command命令最好就bind当前VM object下的command


方法4：ContentControl写在DT里，内部切换ContentTemplate，外部调用用该DT


我之前做的方法是在最上面定义model层而不是vm层简写，而后DT的DataType属性设成了Tool类型，各种Textblockbind到当前vm下面的Tool属性，这样造成button的command binding出现错误，因为在Tool里面没有对应的Command
