问题描述
我正在设置DataGridCells的Validation.ErrorTemplate,这里是xaml代码:
I'm trying to set the Validation.ErrorTemplate of the DataGridCells, here's the xaml code:
<Style x:Key="{x:Type DataGridCell}" x:Uid="dataGridCellErrorTemplate" TargetType="{x:Type DataGridCell}">
<Setter Property="Validation.ErrorTemplate">
<Setter.Value>
<ControlTemplate >
<Border BorderBrush="Green" BorderThickness="2" ToolTip="Heidenei"></Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<!-- following line only for demonstration that the setter is working ... -->
<Setter Property="Background" Value="Aquamarine"></Setter>
</Style>
,而数据网格单元格的背景成功地使用绿色(与任何验证结果无关)使用的验证。 ErrorTemplate仍然是默认的,即红色边框。
while the background of the datagridcells is successfully colored green (independant from any validation result) the used Validation.ErrorTemplate is still the default one, i.e. the red border.
我知道在stackoverflow中有类似的问题,例如
但他们并没有真正解决我的问题
I know there have been similar issues here in stackoverflow, e.g.Styling DataGridCell Error Templatebut they do not really solve my problem.
任何帮助不胜感激

推荐答案
我相信我遇到同样的问题。
I believe that I'm experiencing the same issue.
当使用 DataGridTemplateColumn
时,内容将显示一个 ContentPresenter
。此内容演示者使用默认错误模板。
When using a DataGridTemplateColumn
the content is presented with a ContentPresenter
. This content presenter uses the default error template.
我找不到直接的方法来删除单个 DataGridTemplateColumn
的模板,但可以将其删除通过向DataGrid的资源添加样式,DataGrid中的所有内容呈现者。
I can't find a direct way to remove this template for an individual DataGridTemplateColumn
but you can remove it for all content presenters in the DataGrid by adding a style to the DataGrid's resources.
<DataGrid.Resources>
<Style TargetType="ContentPresenter">
<Setter Property="Validation.ErrorTemplate" Value="{x:Null}"/>
</Style>
</DataGrid.Resources>
