C#:无法以编程方式填充 DataGridView

Question

我没有使用设计器，而是试图填充一个 DataGridView，我已经以编程方式放在我的 Winform 上。当我查看调试器下的表格时，它具有正确的列和行数。问题是网格在我的表单上显示为一个空的灰色框。当我通过 VS 2008 Designer 将网格绑定(bind)到数据库时，它工作正常。如何追踪问题？

更新

我几乎是从这个MSDN Article

更新

除了将网格放到 Winform 上之外，我是否需要在设计器中做任何事情？

namespace CC
{
    public partial class Form1 : Form
    {

        private BindingSource bindingSource1 = new BindingSource();
        private SQLiteDataAdapter dataAdapter = new SQLiteDataAdapter();

        public Form1()
        {
            InitializeComponent();
            dataGridView1 = new DataGridView();

            this.Load += new System.EventHandler(Form1_Load);
            this.Text = "Cars";
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            dataGridView1.DataSource = bindingSource1;
            GetData("select * from Cars");


        }

        private void GetData(string selectCommand)
        {
            string dbPath = "c:\\temp\\cars.db";

            try
            {

                var connectionString = "Data Source=" + dbPath + ";Version=3";

                dataAdapter = new SQLiteDataAdapter(selectCommand, connectionString);

                SQLiteCommandBuilder commandBuilder = new SQLiteCommandBuilder(dataAdapter);


                DataTable table = new DataTable();
                table.Locale = System.Globalization.CultureInfo.InvariantCulture;
                dataAdapter.Fill(table);
                bindingSource1.DataSource = table;

                // Resize the DataGridView columns to fit the newly loaded content.
                dataGridView1.AutoResizeColumns(
                    DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader);
            }
            catch (SqlException)
            {
                MessageBox.Show("To run this example, replace the value of the " +
                    "connectionString variable with a connection string that is " +
                    "valid for your system.");
            }
        }


    }
}

我认为您需要指定 DataMember 属性。而且我认为您不需要绑定(bind)源对象，您可以直接将 DataTable 绑定(bind)到 DataGridView 控件。

我附上了一个代码，它有助于将 gridview 控件与 SQL Server 数据库绑定(bind)，它对我来说工作正常。

using(SqlDataAdapter sqlDataAdapter = 
    new SqlDataAdapter("SELECT * FROM Table1",
        "Server=.\\SQLEXPRESS; Integrated Security=SSPI; Database=SampleDb"))
{
    using (DataTable dataTable = new DataTable())
    {
        sqlDataAdapter.Fill(dataTable);
        this.dataGridView1.DataSource = dataTable;
    }
}

抱歉，我没有安装 SQLite :(
