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：


用于类型DataGridRowEx的样式不能应用于键入
'DataGridRow






这是我的自定义DataGridRow的XAML代码：

非常感谢！

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:

A style intended for type 'DataGridRowEx' cannot be applied to type 'DataGridRow

This's my XAML code for my custom DataGridRow:

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IT屋！
