在WPF DataGrid中基于DataGridTemplateColumn的样式列 [英] Styling columns based on DataGridTemplateColumn in a WPF DataGrid

问题描述

我正在使用WPF DataGrid，其中的一列要求如果该行是可编辑的，则显示编辑超链接-这由该行的支持模型中的布尔标志指示。我能够使用DataGridTemplateColumn实现此目的-没问题。但是，整行的另一项要求是在选择该行时不显示任何突出显示（默认为蓝色背景）。通过在透明背景下定义DataGridCell样式，我能够在其他列上实现此目标，例如

I am using a WPF DataGrid where one of the columns has a requirement to show an "Edit" hyperlink if the row is editable - this is indicated by a boolean flag in the backing model for the row. I was able to achieve this using a DataGridTemplateColumn - no problems. However an additional requirement on the entire row is not to show any highlights when the row is selected (this is a blue background by default). I have been able to achieve this on other columns by defining the DataGridCell style with a transparent background, e.g.

<DataGridTextColumn
    Header="Id"
    Binding="{Binding Path=Id}"
    HeaderStyle="{StaticResource DataGridColumnHeaderStyle}"
    CellStyle="{StaticResource DataGridCellStyle}" />

其中DataGridCellStyle的定义如下：

where DataGridCellStyle is defined as follows:

<Style x:Key="DataGridCellStyle" TargetType="{x:Type DataGridCell}">
    <Setter Property="Background" Value="Transparent" />
    ...
</Style>

但是有问题的列DataGridTemplateColumn没有提供我可以使用的 CellStyle属性用于关闭选择突出显示。所以我的问题是使用DataGridTemplateColumn时如何设置单元格样式？这是我满足第一个要求的列的实现（即，如果行可编辑，则显示编辑超链接）：

However the column in question, a DataGridTemplateColumn, does not offer a "CellStyle" attribute which I can use for turning off selection highlights. So my question is how to set the cell style when using a DataGridTemplateColumn? Here's my implementation of the column which satisfies the first requirement (i.e. showing an "Edit" hyperlink if the row is editable):

<DataGridTemplateColumn
    Header="Actions"
    HeaderStyle="{StaticResource CenterAlignedColumnHeaderStyle}">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock
                Visibility="{Binding Path=Editable, Converter={StaticResource convVisibility}}"
                Style="{StaticResource CenterAlignedElementStyle}">
                    <Hyperlink
                        Command="..."
                        CommandParameter="{Binding}">
                        <TextBlock Text="Edit" />
                    </Hyperlink>
            </TextBlock>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

谢谢。

推荐答案

至少在WPF4中，有一个用于DataGridTemplateColumns的CellStyle： http://msdn.microsoft.com/zh-CN/library/cc189163.aspx

At least in WPF4, there is a CellStyle for DataGridTemplateColumns: http://msdn.microsoft.com/en-us/library/cc189163.aspx
