XamDataGrid字段值作为渐变背景
|
我有Infragistics XamDataGrid，其中有几列以百分比显示数据。
现在，我希望这些列将值显示为百分比，将背景显示为2种颜色的渐变，其中第一种颜色将绑定到百分比值，而第二种颜色将剩余值。
解决方法是模板化cellvaluepresenter，通过它可以对单元格进行样式设置。
您可以使用TargetType = \“ {x：Type igDP：CellValuePresenter} \”创建样式。
但是现在出现了一个问题，即我该如何确定后端产生了什么价值，并根据价值显示背景。
以下是代码。在此代码中，当我在CellValuePresenterStyle中使用StaticResource时。绑定工作正常，但未调用样式中的转换器。当我在CellValuePresenterStyle中使用DynamicResource时，绑定中断，并且列中的值为空。
