Question

我已经以编程方式创建了一个datagridview。因此，没有绑定源或数据源可以将Datagridview和Binidgnavigator连接到它们。有没有其他方法可以将它们相互连接起来。这是我的datafridview代码

帮我将其连接到bindingNavigator

private void Fill()
{
    try
    {
        if (dataGridView1 != null)
        {
            dataGridView1.ColumnCount = 11;
            dataGridView1.Columns[0].HeaderText = Resources.Form1_Fill_ID;
            dataGridView1.Columns[1].HeaderText = Resources.Form1_Fill_Family;
            dataGridView1.Columns[2].HeaderText = Resources.Form1_Fill_Cellphone;
            dataGridView1.Columns[3].HeaderText = Resources.Form1_Fill_Phone1;
            dataGridView1.Columns[4].HeaderText = Resources.Form1_Fill_Phone2;
            dataGridView1.Columns[5].HeaderText = Resources.Form1_Fill_Phone3;
            dataGridView1.Columns[6].HeaderText = Resources.Form1_Fill_Fax;
            dataGridView1.Columns[7].HeaderText = Resources.Form1_Fill_CompanyName;
            dataGridView1.Columns[8].HeaderText = Resources.Form1_Fill_Agency;
            dataGridView1.Columns[9].HeaderText = Resources.Form1_Fill_Brands;
            dataGridView1.Columns[10].HeaderText = Resources.Form1_Fill_Address;

            dataGridView1.Columns[0].Name = Resources.Form1_Fill_ID;
            dataGridView1.Columns[1].Name = Resources.Form1_Fill_Family;
            dataGridView1.Columns[2].Name = Resources.Form1_Fill_Cellphone;
            dataGridView1.Columns[3].Name = Resources.Form1_Fill_Phone1;
            dataGridView1.Columns[4].Name = Resources.Form1_Fill_Phone2;
            dataGridView1.Columns[5].Name = Resources.Form1_Fill_Phone3;
            dataGridView1.Columns[6].Name = Resources.Form1_Fill_Fax;
            dataGridView1.Columns[7].Name = Resources.Form1_Fill_CompanyName;
            dataGridView1.Columns[8].Name = Resources.Form1_Fill_Agency;
            dataGridView1.Columns[9].Name = Resources.Form1_Fill_Brands;
            dataGridView1.Columns[10].Name = Resources.Form1_Fill_Address;
        }

        _conn.ConnectionString = _connectionString;
        var cmd = new OleDbCommand("Select * from contacts ", _conn);
        _conn.Open();
        OleDbDataReader reader = cmd.ExecuteReader();

        int i = 0;
        while (reader != null && reader.Read())
        {
            if (dataGridView1 != null)
            {
                dataGridView1.Rows.Add(1);
            }
            if (dataGridView1 != null)
            {
                var row = dataGridView1.Rows[i];

                row.Cells[Resources.Form1_Fill_ID].Value = reader[0].ToString();
                row.Cells[Resources.Form1_Fill_Family].Value = reader[1].ToString();
                row.Cells[Resources.Form1_Fill_Cellphone].Value = reader[2].ToString();
                row.Cells[Resources.Form1_Fill_Phone1].Value = reader[3].ToString();
                row.Cells[Resources.Form1_Fill_Phone2].Value = reader[4].ToString();
                row.Cells[Resources.Form1_Fill_Phone3].Value = reader[5].ToString();
                row.Cells[Resources.Form1_Fill_Fax].Value = reader[6].ToString();

            }
            i++;
        }

    }
    catch (Exception ex)
    {
        return;
    }
    finally
    {
        _conn.Close();

尝试修改您的代码。您无需在程序上创建列程序，查询本身可以通过DataTable到BindingSource创建一个列，尝试使用此代码并获得一些想法。

BindingNavigator和BindingSource

        string connectionString =
            @"Provider=Microsoft.ACE.OLEDB.12.0;" +
            @"Data Source=D:\myDatabase.accdb;";

        string queryString = "SELECT Name AS FullName, Gender AS Gender, Address AS [Current Address] FROM Person";

        using (OleDbConnection connection = new OleDbConnection(connectionString))
        using (OleDbCommand command = new OleDbCommand(queryString, connection))
        {
            try
            {
                BindingSource bs = new BindingSource();
                OleDbDataAdapter dataAdapter = new OleDbDataAdapter(queryString, connection);
                OleDbCommandBuilder commandBuilder = new OleDbCommandBuilder(dataAdapter);
                DataTable dataTable = new DataTable();
                dataAdapter.Fill(dataTable);
                bs.DataSource = dataTable;
                dataGridView1.DataSource = bs;
                bindingNavigator1.BindingSource = bs;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

将BindingNavigator与以编程方式创建的Datagridview连接
