问题描述
我正在使用一个自定义Datagrid，我想添加一个属性到DatagridRow。我不知道该怎么做我认为我将包装一个自定义的dataGridRow，但我不能在我的自定义DataGrid中使用它。错误消息：
这是我的自定义DataGridRow的XAML代码：

解决方案
我怀疑你还在为DataGridEx的行使用System.Windows.Controls.DataGridRow类型。要使用您自己的DataGridRowEx类型的实例，必须在DataGridEx类中重写GetContainerForItemOverride（）方法：
public class DataGridRowEx： DataGridRow
{
//您可以添加任何自定义依赖属性
}
public class DataGridEx：DataGrid
{
//。 ..
protected override DependencyObject GetContainerForItemOverride（）
{
返回新的DataGridRowEx（）;
}
}
I'm working with a custom Datagrid and I want add a property to a DatagridRow. I don't know how can to do that.I think I will crate a custom dataGridRow but I Can't use it in my Custom DataGrid. Error message:

Thanks so much!
解决方案
I suspect you are still using System.Windows.Controls.DataGridRow type for your DataGridEx's rows. To use the instances of your own DataGridRowEx type, you must override GetContainerForItemOverride() method in your DataGridEx class:
public class DataGridRowEx : DataGridRow
{
// you can add any custom dependency property here
}
public class DataGridEx : DataGrid
{
//...
protected override DependencyObject GetContainerForItemOverride()
{
return new DataGridRowEx();
}
}
这篇关于如何将依赖属性添加到DataGridRow WPF中的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
