我在数据模板中有一个带有标签的 wpf 数据网格。我想将文本的颜色绑定到一个属性,但它不起作用。
这是xaml。
<DataGrid x:Name="ResultsDataGrid" CanUserSortColumns="True" MouseDown="ResultsDataGrid_OnMouseDown" SelectionChanged="ResultsDataGrid_OnSelectionChanged"
IsReadOnly="False" AlternatingRowBackground="WhiteSmoke" CanUserAddRows="False" Margin="10" AutoGenerateColumns="False" VerticalAlignment="Stretch">
<DataGrid.Columns>
<DataGridTemplateColumn Header="Test ID" Width="150" IsReadOnly="True" SortMemberPath="TestDate">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Label Foreground="{Binding PassedColor}" Content="{Binding TestID}"></Label>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
这里是财产。
public Brush PassedColor
{
get
{
return new SolidBrush(Color.Red);
}
}
我似乎无法弄清楚我做错了什么。
如果它删除绑定并将前景设置为red
它可以工作。所以这绝对是绑定的东西。

这是整个对象
