更改WPF Datagrid行颜色 [英] Change WPF Datagrid Row Color

问题描述

现在我想根据程序开始的行内容对行进行着色，如果有改变在运行时。

  System.Windows.Controls.DataGrid areaDataGrid = ...; 
 ObservableCollection< Area>区域; 
 //向区域集合添加项目
 areaDataGrid.ItemsSource = areas; 
 
 areaDataGrid.Rows<  - 属性不可用。如何访问行？ 
 
 CollectionView myCollectionView =（CollectionView）CollectionViewSource.GetDefaultView（areaDataGrid.Items）; 
（（INotifyCollectionChanged）myCollectionView）.CollectionChanged + = new NotifyCollectionChangedEventHandler（areaDataGrid_Changed）; 
 ... 
 
 void areaDataGrid_Changed（object sender，NotifyCollectionChangedEventArgs e）
 {
 //如何访问更改的行？ 
} 
  

如何在开始和运行时访问行？

解决方案

使用 RowStyle 。您可以使用 触发器 有条件地更改颜色，或者只是将其绑定到您的项目上的画笔属性，并分别更改该属性。

I have a WPF datagrid that is filled with an ObserverableCollection.

Now I want to color the rows depending on the row content at the program start and if something changes during runtime.

System.Windows.Controls.DataGrid areaDataGrid = ...;
ObservableCollection<Area> areas;
//adding items to areas collection
areaDataGrid.ItemsSource = areas;

areaDataGrid.Rows  <-- Property not available. how to access rows here?

CollectionView myCollectionView = (CollectionView)CollectionViewSource.GetDefaultView(areaDataGrid.Items);
((INotifyCollectionChanged)myCollectionView).CollectionChanged += new NotifyCollectionChangedEventHandler(areaDataGrid_Changed);
...

void areaDataGrid_Changed(object sender, NotifyCollectionChangedEventArgs e)
{
    //how to access changed row here?
}

How can I access the rows at start and runtime?

解决方案

Use the RowStyle. You can use the Triggers to change the color conditionally, or just bind it to a Brush property on your items and change that property respectively.
