I have this DataGrid :
I would like to add at the bottom of DataGrid a Row that contain Name: Total and Price: the Sum of all price. And if is possible that this row will be frozen. Do you have any ideas? The simple project is in this link : here
EDIT 1 This is the XAML code:
<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>
and this is the 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;
}
}
您可以在数据网格下方添加一个文本块,然后将其绑定到具有总价的属性,而不是在数据网格中添加最后一行。
This should be helpful.i only added a new row with a method for making the sum
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;
}
Regards
one more:
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;
}
