我正在开发Windows 8商店应用程序(c#)。我有一个从存储库获取项目的组合框(cboTeam1)。

private static List<TeamItem> JPLItems = new List<TeamItem>();
public static List<TeamItem> getJPLItems()
    {
        if (JPLItems.Count == 0)
        {
            JPLItems.Add(new TeamItem() { Id = 1, Description = "Anderlecht", Image = "Jpl/Anderlecht.png", ItemType = ItemType.JPL });
            JPLItems.Add(new TeamItem() { Id = 1, Description = "Beerschot", Image = "Jpl/Beerschot.png", ItemType = ItemType.JPL });
            JPLItems.Add(new TeamItem() { Id = 1, Description = "Cercle Brugge", Image = "Jpl/Cercle.png", ItemType = ItemType.JPL });
            JPLItems.Add(new TeamItem() { Id = 1, Description = "Charleroi", Image = "Jpl/Charleroi.png", ItemType = ItemType.JPL });
        }
        return JPLItems;
    }

我加载的项目在cboTeam1的ItemsSource:

cboTeam1.ItemsSource = ItemRepository.getJPLItems();

当cboTeam1 selectionchanged时，我这样做:

    private void cboTeam1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        Ploeg1.Text = cboTeam1.SelectedValue.ToString();               
    }

结果是:SportsBetting.Model.TeamItem

谁能帮助我得到组合框的选择值在我的文本块(Ploeg1.Text)??

c# windows 8 selected comboboxitem

你几乎自己回答了这个问题。

private void cboTeam1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
        // cast the selected item to the correct type.
    var selected = cboTeam.SelectedValue as TeamItem;
        //then access the appropriate property on the object, in this case "Description"
        // note that checking for null would be a good idea, too.
    Ploeg1.Text = selected.Description;               
}

另一个选择是重写TeamItem类中的ToString()来返回Description。在这种情况下，原始代码应该可以正常工作。

public override string ToString()
{
    return this._description;  // assumes you have a backing store of this name
}
