通過按鈕點擊C#Winform獲取動態創建表單中每條記錄的ID

Question

我有一個表格，可以返回某個醫生的所有預約。 我想知道的是如何獲取每個返回數據的ID。

這就是我想要實現的目標。 1. 根據此特定醫生的預約次數動態創建控件。 2. 編輯每個約會 - 但為了做到這一點。 我需要通過點擊事件獲取特定面板的 ID。 我現在擁有的是..我只得到最后一條記錄的ID——

MySqlConnection con = new MySqlConnection("Server = localhost ;Database = mica_userclient_laravel; username = root;");
// MySqlConnection con = new MySqlConnection("Server = sql12.freemysqlhosting.net; Database = sql12221392; Uid=sql12221392; Password=5gZN1uN6NX;");
MySqlDataAdapter da = new MySqlDataAdapter(@"SELECT users.id, 
        users.fname, users.mname, users.lname, 
        appointments.created_at, appointments.id, 
        appointments.status 
        FROM users, appointments 
        WHERE users.id = user_id 
          AND appointments.status = 0 
          AND appointments.client_id = '" + textBox2.Text + "'", con);

DataTable dt = new DataTable();
da.Fill(dt);
//textBox1.Text = dt.Rows[1].ItemArray[5].ToString();

//login.quantity = textBox2.Text;

//label4.Text = Convert.ToDateTime(dt.Rows[1].ItemArray[4]).ToString("MMM dd, yyyy");
//label7.Text = Convert.ToDateTime(dt.Rows[1].ItemArray[4]).ToString("h:mm tt");
//label3.Text = dt.Rows[1].ItemArray[3].ToString() + ", " + dt.Rows[1].ItemArray[1].ToString();

for (int i = 0; i < dt.Rows.Count; i++)
{

    textBox[i] = new TextBox();
    textBox[i].Name = "n" + i;
    textBox[i].Text = dt.Rows[i].ItemArray[5].ToString();
    textBox[i].Visible = true;
    textBox[i].Location = new Point(txtboxX, txtboxY);
    txtboxY += 25;
    panel[i] = new Panel();
    panel[i].Name = "n" + i;
    panel[i].Width = 793;
    panel[i].Height = 56;
    panel[i].BackColor = Color.WhiteSmoke;
    panel[i].Location = new Point(panelX, panelY);
    panelY += 80;




    label[i] = new Label();
    label[i].Name = "n" + i;
    //label[i].Parent = panel[i];
    label[i].Font = new Font("Century Gothic", 14);
    label[i].Height = 22;
    label[i].Width = 250;
    label[i].ForeColor = Color.Gray;
    label[i].Text = dt.Rows[i].ItemArray[2].ToString() + ", " + dt.Rows[i].ItemArray[1].ToString();
    label[i].Location = new Point(labelX, labelY);

    label1[i] = new Label();
    label1[i].Name = "n" + i;
    //label[i].Parent = panel[i];
    label1[i].Font = new Font("Century Gothic", 14, FontStyle.Bold);
    label1[i].Height = 22;
    label1[i].Width = 250;
    label1[i].ForeColor = Color.Gray;
    label1[i].Text = Convert.ToDateTime(dt.Rows[i].ItemArray[4]).ToString("MMM dd, yyyy - h:mm tt");
    label1[i].Location = new Point(label1X, label1Y);

    imgbtn[i] = new BunifuImageButton();
    imgbtn[i].BackColor = Color.Transparent;
    imgbtn[i].SizeMode = PictureBoxSizeMode.Zoom;
    imgbtn[i].ImageLocation = @"Image\edit.png";
    imgbtn[i].Width = 46;
    imgbtn[i].Height = 38;
    //imgbtn[i].ImageActive = @"Image\edit2.png";
    imgbtn[i].Location = new Point(imgbtnX, imgbtnY);
    imgbtn[i].Click += new EventHandler(bunifuImageButton1_Click);


    this.Controls.Add(panel[i]);
    this.Controls.Add(label[i]);
    this.Controls.Add(imgbtn[i]);
    this.Controls.Add(textBox[i]);
    panel[i].Controls.Add(label[i]);
    panel[i].Controls.Add(label1[i]);
    panel[i].Controls.Add(imgbtn[i]);

    gumanaka = textBox[i].Text;
}

單擊它時，您可以使用 DataRowView 獲取表格的列..

對於表的選擇更改事件的示例，您可以使用：

DataRowView dr = table_name.SelectedItem as DataRowView;
int id = Convert.ToInt32(dr["appointments_id"]);

或者在您的情況下，如果它是第 5 個元素：

int id = Convert.ToInt32(dr[4]);

只需檢查值

MessageBox.Show(dr.ToString());
