winForms + DataGridView 绑定到 List（视觉工作室 2005、C# 2.0）

Question

我有以下代码，但 DatGridView 显示空行。我找不到解决方案。我已将 AutoGenerateColumns 设置为 false。如果我将其设置为 true，它会创建行，但不允许我将此属性设置为 true （客户希望）。

我做错了什么？这是代码：

public partial class Form1 : Form
{
    private List<AStruct> _aCollectionList;
    private BindingList<AStruct> _aCollectionBindingList;

    public struct AStruct
    {
        public string ACode
        {
            get { return _aCode; }
            set { _aCode = value; }
        }

        public string AName
        {
            get { return _aName; }
            set { _aName = value; }
        }

        private string _aCode;
        private string _aName;
    }

    public Form1()
    {
        InitializeComponent();
        this.dataGridView1.AutoGenerateColumns = false;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        _aCollectionList = new List<AStruct>();
        FillCollectionStruct(true);

        dataGridView1.DataSource = _aList;
        dataGridView1.Refresh();            
    }

    private void button2_Click(object sender, EventArgs e)
    {            
        _aCollectionBindingList = new BindingList<AStruct>();
        FillCollectionStruct(false);
        dataGridView1.DataSource = _aBindingList;
        dataGridView1.Refresh();         
    }

    private void FillCollectionStruct(bool listBool)
    {
        AStruct aStruct = new AStruct();

        for (int i = 0; i < 10; i++)
        {
            aStruct.ACode = i.ToString();
            aStruct.AName = i.ToString();

            if (listBool)
                _aCollectionList.Add(aStruct);
            else
                _aCollectionBindingList.Add(aStruct);
        }
    }
}

在 Form1.Designer 中，我确实创建了以下列：

// 
// aCodeColumn
// 
this.colorCodeColumn.DataPropertyName = "Code";
this.colorCodeColumn.HeaderText = "a code";
this.colorCodeColumn.Name = "aCodeColumn";
// 
// aNameColumn
// 
this.colorNameColumn.DataPropertyName = "Name";
this.colorNameColumn.HeaderText = "a name";
this.colorNameColumn.Name = "aNameColumn";

Answer 1

难道你不能将绑定从： 更改

// aCodeColumn
// 
this.colorCodeColumn.DataPropertyName = "Code";
this.colorCodeColumn.HeaderText = "a code";
this.colorCodeColumn.Name = "aCodeColumn";
// 
// aNameColumn
// 
this.colorNameColumn.DataPropertyName = "Name";
this.colorNameColumn.HeaderText = "a name";
this.colorNameColumn.Name = "aNameColumn";

为：

// aCodeColumn
// 
this.colorCodeColumn.DataPropertyName = "ACode";
this.colorCodeColumn.HeaderText = "a code";
this.colorCodeColumn.Name = "aCodeColumn";
// 
// aNameColumn
// 
this.colorNameColumn.DataPropertyName = "AName";
this.colorNameColumn.HeaderText = "a name";
this.colorNameColumn.Name = "aNameColumn";

这不应该起作用吗？

由于 DataPropertyName 是绑定到属性的名称，因此名称必须相同，否则编译器无法知道什么放在哪里。

如果我理解你的问题，你可以使用这样的东西。dataGridView1.Refresh();为了重新填充它，并在刷新行之前放置 this.dataGridView1.DataSource = _aCollectionBindingList;
