一个业余爱好者试图完成我的第一个真正的应用程序，所以提前谢谢你，如果这是一个菜鸟问题，我们深表歉意。

我有一个启用拖放的数据网格视图，其中填充了来自团队类的数据和一个字典，它根据索引为列表中的项目分配一个值。我还没有实现绑定，因为我还没有让它与拖放行重新排序一起工作。

teamList = new List<Team>(){
    new Team("Redskins","WAS", "Washington"),
    new Team("Cowboys", "DAL", "Dallas"),
    new Team("Eagles", "PHI", "Philadelphia"),
    new Team("Giants", "NYG", "New York"),
    new Team("Packers", "GB", "Green Bay")
 };

class Team
{
    public string Mascot { get; private set; }
    public string Key { get; private set; }
    public string City { get; private set; }
}

Dictionary<int, int> powerValues = new Dictionary<int, int>(){
    {1, 113},
    {2, 110},
    {3, 109},
    {4, 108},
    {5, 107}
};

private void printValues()
{   // add Team to DGV wiht PowerRank as index+1 and PowerValue based on Dictionary
    int i = 0;
    foreach (Team team in TeamList)
    {                
        // add all data to a datagrid view
        dataGridView1.Rows.Add(i+1, team.Mascot,powerValues[teamList.IndexOf(team) + 1]); //set the rank
        i++;
    }
}

一旦达到这一点，我将尝试做两件事：

1) Update List<Team> based on drag and drop change
2) Re-assign PowerRank and PowerValue based on new index of Team

我尝试了几件事无济于事-有正确方向的想法或要点吗？

我已经通过一种新方法绕过了#2，但这并不是我希望如此开放以进行改进的优雅解决方案。仍在工作#2

    private void reEstablishRanking()
    {
        for (int i = 0; i < defaultPR.TeamList.Count; i++)
        {
            dataGridView1.Rows[i].Cells["PowerRank"].Value = (i + 1);
            dataGridView1.Rows[i].Cells["PowerValue"].Value = defaultPR.PRScores[i + 1];
        }
    }
