如何在Xceed DataGrid for WPF中检测行选择 [英] How do I detect row selection in the Xceed DataGrid for WPF

问题描述

我正在使用Xceed DataGrid for WPF，而我需要知道什么时候有人选择一排，但我不知道如何做到这一点。我确定我需要添加一些XAML来启用此功能，但我无法弄明白我应该做什么。

解决方案

我使用MVVM方法，因此有利于数据绑定。我将把SelectedItem属性绑定到GridModel对象上的一个SelectedItem属性。

 < xcdg：DataGridControl x：Name =gridSelectedItem ={Binding SelectedItem}> 
< / xcdg：DataGridControl> 
  

然后在您的属性设置器可以在SelectedItemChanged（）方法中进行更改所需的功能。 / p>

 私人IMyItem _selectedItem; 
 public IMyItem SelectedItem 
 {
 get {return _selectedItem; } 
 set {
 _selectedItem = value; 
 OnPropertyChanged（SelectedItem）; 
 SelectedItemChanged（）; 
} 
} 
  

I'm horrible at this WPF thing, so bear with me.

I'm using the Xceed DataGrid for WPF, and I need to know when someone selects a row, but I can't figure out how to do it. I'm sure I need to add some XAML to enable this, but I can't figure out what I should do.

解决方案

I use a MVVM approach and therefor favor data binding. I will bind the SelectedItem property to a SelectedItem property on my ViewModel object for the grid.

<xcdg:DataGridControl x:Name="grid" SelectedItem="{Binding SelectedItem}">
</xcdg:DataGridControl>

Then on your property setter can do what ever is necessary upon change in the SelectedItemChanged() method.

private IMyItem _selectedItem;
public IMyItem SelectedItem
{
   get { return _selectedItem; }
   set { 
          _selectedItem = value;
          OnPropertyChanged("SelectedItem");
          SelectedItemChanged();
       }
}
