从 TableAdapter 插入后 DataGridView 未更新答案

【问题标题】：DataGridView not updating after an Insert from TableAdapter从 TableAdapter 插入后 DataGridView 未更新
【发布时间】：2015-10-30 15:28:22
【问题描述】：

在我的 form1 中，我正在插入

tableAdapterManager.BatchTableAdapter.Insert(Int32.Parse(Maxorder) + 10, DateTime.Now, DateTime.Now, Int32.Parse(txtData0.Value.ToString()), 1);

所以它将参数添加到我的 LocalDb 中，然后我转到 form2，它应该在 dataGridView 中显示结果。此 DataGridView 与 DataSource 一起成为 View。仅当我重新启动应用程序时，视图才显示“插入”参数。我试过了：

v_BatchTableAdapter.Fill(dbSahara.v_Batch);

但我只在打开应用程序之前插入数据。

如果有人可以帮助我...在此先感谢。

我这样做“修复”了它：

 private void GetData(string selectCommand)
    {
        try
        {
            // Specify a connection string. Replace the given value with a 
            // valid connection string for a Northwind SQL Server sample
            // database accessible to your system.
            String connectionString =
                "Integrated Security=SSPI;Persist Security Info=False;" +
                "Initial Catalog=Northwind;Data Source=localhost";

            // Create a new data adapter based on the specified query.
            dataAdapter = new SqlDataAdapter(selectCommand, connectionString);

            // Create a command builder to generate SQL update, insert, and
            // delete commands based on selectCommand. These are used to
            // update the database.
            SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter);

            // Populate a new data table and bind it to the BindingSource.
            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.");
        }
    }
