WPF DataGridTemplateColumn共享模板？ [英] WPF DataGridTemplateColumn shared template?

问题描述

我有一个datagrid，它有很多datagridtemplate列都是完全相同的，除了它们在模板的stackpanel上都有不同的数据文本。

 < toolkit：DataGridTemplateColumn Header =Col 1> 
< toolkit：DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< StackPanel DataContext ={Binding Times [0]}> 
<！ - 我想提取到模板的结构 - > 
< / StackPanel> 
< / DataTemplate> 
< / toolkit：DataGridTemplateColumn.CellTemplate> 
< / toolkit：DataGridTemplateColumn> 
 
< toolkit：DataGridTemplateColumn Header =Col 2> 
< toolkit：DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< StackPanel DataContext ={Binding Times [1]}> 
<！ - 这里结构相同 - > 
< / StackPanel> 
< / DataTemplate> 
< / toolkit：DataGridTemplateColumn.CellTemplate> 
< / toolkit：DataGridTemplateColumn>我想让每个列使用一个特定的itemtemplate（就像我已经做了一个listbox），但是似乎看不到除非我错过了一些东西。
解决方案
您可以使用ContentPresenter为每个列：
 < toolkit：DataGrid.Resources> 
< DataTemplate x：Key =ColumnTemplate> 
< StackPanel> 
<！ - 我要提取到模板的结构 - > 
< / StackPanel> 
< / DataTemplate> 
< / toolkit：DataGrid.Resources> 
< toolkit：DataGrid.Columns> 
< toolkit：DataGridTemplateColumn Header =Col 1> 
< toolkit：DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< ContentPresenter ContentTemplate ={StaticResource ColumnTemplate}Content ={Binding Times [0]}/> 
< / DataTemplate> 
< / toolkit：DataGridTemplateColumn.CellTemplate> 
< / toolkit：DataGridTemplateColumn> 
< toolkit：DataGridTemplateColumn Header =Col 2> 
< toolkit：DataGridTemplateColumn.CellTemplate> 
< DataTemplate> 
< ContentPresenter ContentTemplate ={StaticResource ColumnTemplate}Content ={Binding Times [1]}/> 
< / DataTemplate> 
< / toolkit：DataGridTemplateColumn.CellTemplate> 
< / toolkit：DataGridTemplateColumn> 
< / toolkit：DataGrid.Columns> 
  
如果时代的元素都是相同的类型，您还可以执行 < DataTemplate DataType = {x：Type YourType}> 然后您不需要指定 ContentTemplate ={StaticResource ColumnTemplate}在每一列。 
 
Hi I have a datagrid that has a number of datagridtemplate columns that are all identical apart from they each have a different datacontext on the template's stackpanel.
<toolkit:DataGridTemplateColumn Header="Col 1">
                <toolkit:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel DataContext="{Binding Times[0]}">
                        <!-- the structure that I want to extract to a template -->
                        </StackPanel>
                    </DataTemplate>
                </toolkit:DataGridTemplateColumn.CellTemplate>
</toolkit:DataGridTemplateColumn>

<toolkit:DataGridTemplateColumn Header="Col 2">
                <toolkit:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel DataContext="{Binding Times[1]}">
                        <!-- the same structure here -->
                        </StackPanel>
                    </DataTemplate>
                </toolkit:DataGridTemplateColumn.CellTemplate>
</toolkit:DataGridTemplateColumn>
I want to have each column use a specific itemtemplate (like I've done with a listbox) but can't seem to see how unless I'm missing something.
解决方案
You could use a ContentPresenter to instantiate a DataTemplate for each column: 
<toolkit:DataGrid.Resources>
    <DataTemplate x:Key="ColumnTemplate">
        <StackPanel>
            <!-- the structure that I want to extract to a template -->
        </StackPanel>
    </DataTemplate>
</toolkit:DataGrid.Resources>
<toolkit:DataGrid.Columns>
    <toolkit:DataGridTemplateColumn Header="Col 1">
        <toolkit:DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <ContentPresenter ContentTemplate="{StaticResource ColumnTemplate}" Content="{Binding Times[0]}"/>
            </DataTemplate>
        </toolkit:DataGridTemplateColumn.CellTemplate>
    </toolkit:DataGridTemplateColumn>
    <toolkit:DataGridTemplateColumn Header="Col 2">
        <toolkit:DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <ContentPresenter ContentTemplate="{StaticResource ColumnTemplate}" Content="{Binding Times[1]}"/>
            </DataTemplate>
        </toolkit:DataGridTemplateColumn.CellTemplate>
    </toolkit:DataGridTemplateColumn>
</toolkit:DataGrid.Columns>
If the elements of Times are all the same type, you could also do <DataTemplate DataType={x:Type YourType}> and then you wouldn't need to specify ContentTemplate="{StaticResource ColumnTemplate}" on each column.
