c# WPF -在DataGrid中添加总行
c# WPF -在DataGrid中添加总行
提问于 2014-02-21 10:19:54
我有一个DataGrid：
我想在DataGrid的底部添加一个包含名称:总计和价格:所有价格之和的行。如果有可能，这一行将被冻结。你有什么想法吗？这个简单的项目在这个链接中：这里
编辑1这是XAML代码：
<DataGrid ItemsSource="{Binding Articles}" AutoGenerateColumns="False" HorizontalAlignment="Left" CanUserAddRows="False" IsReadOnly="True">
<DataGrid.Columns>
<DataGridTextColumn Header="Name" Binding="{Binding Name}"/>
<DataGridTextColumn Header="Price" Binding="{Binding Price}" />
</DataGrid.Columns>
</DataGrid>这是ViewModel：
[Export(typeof(IShell))]
public class MainViewModel : Screen
{
public System.ComponentModel.ICollectionView Articles { get; set; }
public MainViewModel()
{
Articles = CollectionViewSource.GetDefaultView(GetArticles());
}
private List<Article> GetArticles()
{
List<Article> arts = new List<Article>();
arts.Add(new Article { Name = "Name1", Price = 2.80 });
arts.Add(new Article { Name = "Name2", Price = 1.25 });
arts.Add(new Article { Name = "Name3", Price = 9.32 });
arts.Add(new Article { Name = "Name4", Price = 1.31 });
arts.Add(new Article { Name = "Name5", Price = 0.80});
arts.Add(new Article { Name = "Name6", Price = 2.50});
arts.Add(new Article { Name = "Name7", Price = 0.50 });
return arts;
}

再来一次：
private List<Article> GetArticles()
{
List<Article> arts = new List<Article>();
arts.Add(new Article { Name = "Name1", Price = 2.80 });
arts.Add(new Article { Name = "Name2", Price = 1.25 });
arts.Add(new Article { Name = "Name3", Price = 9.32 });
arts.Add(new Article { Name = "Name4", Price = 1.31 });
arts.Add(new Article { Name = "Name5", Price = 0.80 });
arts.Add(new Article { Name = "Name6", Price = 2.50 });
arts.Add(new Article { Name = "Name7", Price = 0.50 });
arts.Add(new Article { Name = "Total", Price = arts.Sum(l => l.Price)});
return arts;

与其将最后一行添加到数据集中，不如在数据集下面添加一个文本块，并将其绑定到具有总价的属性。

这应该是有帮助的。我只添加了一个新行，并使用了一种计算和的方法
private List<Article> GetArticles()
{
List<Article> arts = new List<Article>();
arts.Add(new Article { Name = "Name1", Price = 2.80 });
arts.Add(new Article { Name = "Name2", Price = 1.25 });
arts.Add(new Article { Name = "Name3", Price = 9.32 });
arts.Add(new Article { Name = "Name4", Price = 1.31 });
arts.Add(new Article { Name = "Name5", Price = 0.80 });
arts.Add(new Article { Name = "Name6", Price = 2.50 });
arts.Add(new Article { Name = "Name7", Price = 0.50 });
arts.Add(new Article {Name = "Total", Price = GetTotal(arts)});
return arts;
}
private double GetTotal(List<Article> arts)
{
double Total = 0;
foreach (Article art in arts)
{
Total += double.Parse(art.Price.ToString());
}
return Total;
}问候
