C# (winforms) - 动态更新 DataGridView 和 DataSet答案

【问题标题】：C# (winforms) - Updating a DataGridView and a DataSet dynamicallyC# (winforms) - 动态更新 DataGridView 和 DataSet
【发布时间】：2020-06-13 02:58:34
【问题描述】：

我正在尝试通过 controls.find 访问 DataGridView 以更新数据库然后刷新它（它的数据源是 DataSet）。

这是我目前拥有的代码：

conn = new MySqlConnection(connStr);
conn.Open();

commandInsert = new MySqlCommand(@"INSERT INTO logbook.item
                                (id_type,id_parent,column0001,column0002,column0003,column0004,column0005,column0006,column0007,column0008,column0009,column0010,column0011,column0012,

mySqlDataAdapter.InsertCommand = commandInsert;
mySqlDataAdapter.UpdateCommand = commandUpdate;

DataSet dataSetSender = new DataSet();
DataView dataViewSender = new DataView();
DataTable dataTableSender = new DataTable();
DataGridView dataGridViewReferer = new DataGridView();

dataGridViewReferer = this.Controls.Find(dataGridViewSender, true).FirstOrDefault() as DataGridView;
dataViewSender = (DataView)dataGridViewReferer.DataSource;
dataTableSender = dataViewSender.ToTable();
dataSetSender.Tables.Add(dataTableSender);

mySqlDataAdapter.Update(dataSetSender);
conn.Close();
conn.Dispose();

dataGridViewReferer.Update();
dataGridViewReferer.Refresh();

不幸的是，插入正在工作，而不是只插入一行，而是每次都插入所有 DataGridView 行（更新也执行相同的行为）。

正如一些注释，DataSet 名称是在 Form_Load 上创建的，其名称保存在实际数据库中。

这背后的目标是能够在运行时生成 DataGridView 并以相同的方式为它们分配 DataSet。

DataGridView 是通过单击按钮创建的：

ID = generateID();

dataGridView = new DataGridView();
dataGridView.Name = "dataGridView_" + loadedLogbook_filtered + "_" + ID;
dataGridView.Text = dataGridView.Name;
dataGridView.Location = new Point(8, 32);
dataGridView.Size = new Size(504, 504);
dataGridView.Visible = true;
dataGridView.ContextMenuStrip = contextMenuStrip_main;

dataGridView.MouseDown += new MouseEventHandler(control_MouseDown);
dataGridView.MouseUp += new MouseEventHandler(control_MouseUp);
dataGridView.MouseMove += new MouseEventHandler(control_MouseMove);
dataGridView.MouseClick += new MouseEventHandler(control_MouseClick);
dataGridView.CellValueChanged += new DataGridViewCellEventHandler(control_CellValueChanged);

this.Controls.Add(dataGridView);
ControlMoverOrResizer.Init(dataGridView);

我找不到问题的根源，我需要一点帮助。

有人可以就这个问题给我一些帮助吗？

感谢您的宝贵时间和帮助，非常感谢。

编辑：

这是我创建数据集的方式：

DataGridView dataGridViewReferer = this.Controls.Find(dataGridViewSender, true).FirstOrDefault() as DataGridView;
bool form_contextMenuStrip_main_dataSet_setbuttonDataSetSetClicked = false;

using (Form_contextMenuStrip_main_dataSet_set form_contextMenuStrip_main_dataSet_set = new Form_contextMenuStrip_main_dataSet_set())
{
    form_contextMenuStrip_main_dataSet_set.ShowDialog(this);
    form_contextMenuStrip_main_dataSet_setbuttonDataSetSetClicked = form_contextMenuStrip_main_dataSet_set.buttonDataSetSetClicked;
    dataSetToSet = form_contextMenuStrip_main_dataSet_set.dataSetToSet;

    if (form_contextMenuStrip_main_dataSet_setbuttonDataSetSetClicked == true)
    {
        dataSetToSetRefererer = new DataSet();
        DataSet dataSetCaller = new DataSet();

        conn = new MySqlConnection(connStr);
        conn.Open();

        mySqlDataAdapter = new MySqlDataAdapter();

        command = new MySqlCommand(@"SELECT

                                    item 
                                    WHERE
                                    id_type = @param_0001 and friendly_name=@param_0002", conn);

        command.Parameters.AddWithValue("@param_0001", 4);
        command.Parameters.AddWithValue("@param_0002", dataSetToSet);

        mySqlDataAdapter.SelectCommand = command;
        mySqlDataAdapter.Fill(dataSetCaller);

        conn.Close();
        conn.Dispose();

        string dataSetToFill = dataSetCaller.Tables[0].Rows[0][4].ToString();

        conn = new MySqlConnection(connStr);
        conn.Open();

        mySqlDataAdapter = new MySqlDataAdapter();

        command = new MySqlCommand(@"SELECT

                                    WHERE
                                    id_parent = @param_0001", conn);

        command.Parameters.AddWithValue("@param_0001", dataSetCaller.Tables[0].Rows[0][0].ToString());

        mySqlDataAdapter.SelectCommand = command;
        mySqlDataAdapter.Fill(dataSetToSetRefererer);

        conn.Close();
        conn.Dispose();
        dataGridViewReferer.DataSource = dataSetToSetRefererer.Tables[0].DefaultView;

    }
}

【问题讨论】：

您的问题到底是什么？ datagridview 有一个数据源，它可以是您的数据集，也可以是它的最后一个表，在分配您格式化视图（混合列重新格式化...）然后点网与数据库交互，然后您只更新数据适配器，至少我正在这样做。
问题是，每当我点击 DataGridView 并修改一个单元格，甚至插入一个新单元格时，如果 DataGridView 中有 10 行，它会将所有 10 行重新插入到数据库（即使在单元格更新时）。
正如我之前在评论中所说，尝试仅将 data.apdater 更新到作为 datagridview 数据源的显示表中。见dev.mysql.com/doc/connector-net/en/…
我最初尝试过：dataGridViewReferer = this.Controls.Find(dataGridViewSender, true).FirstOrDefault() as DataGridView; dataViewSender = (DataView)dataGridViewReferer.DataSource; dataTableSender = dataViewSender.Table; dataSetSender.Tables.Add(dataTableSender); mySqlDataAdapter.Update(dataSetSender); conn.Close(); conn.Dispose();这就是我得到的（错误）：DataTable 已经属于另一个 DataSet
请尝试这种方法solibnis.blogspot.com/2013/02/… 并首先使用一个表，然后再添加第二个表。就像我经常在这里重复一样，编程就像写一个行动时间表。

【解决方案1】：

经过进一步测试，罪魁祸首是我使用的是CellValueChanged而不是DataGridView的RowValidated。

这是对我有用的代码，使用 nbk 提供的链接（这真的很有帮助）：

private void control_RowValidated(object sender, DataGridViewCellEventArgs e)
{
    DataGridView dataGridViewReferer = this.Controls.Find(dataGridViewSender, true).FirstOrDefault() as DataGridView;

    DataTable changes = ((DataTable)dataGridViewReferer.DataSource).GetChanges();

    if (changes != null)
    {
        conn = new MySqlConnection(connStr);
        conn.Open();

        command = new MySqlCommand(@"SELECT * from item WHERE id_type=@param_0001 and id_parent=@param_0002", conn);

        command.Parameters.AddWithValue("@param_0001", 5);
        command.Parameters.AddWithValue("@param_0002", 2);

        commandInsert = new MySqlCommand(@"INSERT INTO logbook.item
                                        (id_type,id_parent,column0001,column0002,column0003,column0004,column0005,column0006,column0007,column0008,column0009,column0010,column0011,column0012,
