我创建了一个绑定列表BindingList<RunData>并通过它CustomMessageBox.Show()DataGridView不显示列表元素。

public partial class CustomMessageBox : Form
{
    #region Fields.

    private static CustomMessageBox customMessageBox;

    private static String selectedDateTime;

    #endregion

    #region Properties.

    internal String SelectedDateTime
    { get { return CustomMessageBox.selectedDateTime; } }

    #endregion

    #region Constructors.

    private CustomMessageBox()
    {
        InitializeComponent();            
    }

    #endregion

    #region Methods.

    internal static DialogResult Show(BindingList<RunData> dataGridViewData)
    {
        CustomMessageBox.customMessageBox = new CustomMessageBox();
        CustomMessageBox.customMessageBox.dataGridViewRunData.AutoGenerateColumns = true;
        CustomMessageBox.customMessageBox.dataGridViewRunData.DataSource = dataGridViewData;            
        return CustomMessageBox.customMessageBox.ShowDialog();            
    }

    #endregion
}

internal class RunData
{
    #region Fields.

    private String dateTime;

    private String name;

    private String product;

    private String result;

    #endregion

    #region Properties.

    internal String DateTime
    { get { return this.dateTime; } }

    internal String Name
    { get { return this.name; } }

    internal String Product
    { get { return this.product; } }

    internal String Result
    { get { return this.result; } }

    #endregion

    #region Constructors.

    internal RunData(String dateTime, String name, String product, String result)
    {
        this.dateTime = dateTime;
        this.name = name;
        this.product = product;
        this.result = result;
    }

    #endregion
}

我以前从未使用BindingList过,但从我在网上找到的示例看来,我做的一切都很好。任何帮助,将不胜感激。

谢谢!

如果这有什么不同,我正在使用 .NET 2.0。

在我的测试中,我发现模型类(即 RunData)和/或属性应该是公共的而不是内部的。

我创建了一个示例类,并对网格进行了相同的设置。它因内部属性和类而失败。一旦我公开它就很好了。

  public class RunData
  {
        #region Fields.

        private String dateTime;

        private String name;

        private String product;

        private String result;

        #endregion

        #region Properties.

        public String DateTime
        { get { return this.dateTime; } }

        public String Name
        { get { return this.name; } }

        public String Product
        { get { return this.product; } }

        public String Result
        { get { return this.result; } }

        #endregion

        #region Constructors.

        public RunData(String dateTime, String name, String product, String result)
        {
            this.dateTime = dateTime;
            this.name = name;
            this.product = product;
            this.result = result;
        }

        #endregion
  }
