更新TabPage中UserControl中的標簽

感謝stackoverflow，我能夠為我的專案動態創建標簽頁。我遇到的問題是如何更新我在 TabPanel TabPages 中的 UserControl 中的內容。

這是我當前創建選項卡的方式（沒有創建一個默認選項卡，因為它永遠不會改變所有其他選項卡都是在 frm_load 時創建的）

private void TechnicianInfo()
        {
            var techSheet = smartSheet.SheetResources.GetSheet(
                0000000000000000, // all 0's for security purposes
                null,
                null,
                null,
                null,
                null,
                null,
                null);

            // API identifies columns by ID, but it's more convenient to refer to column names
            Dictionary<string, long> technicianMap = new Dictionary<string, long>();

            // Build the column map for easier reference
            foreach (Column column in techSheet.Columns)
                technicianMap.Add(column.Title, (long)column.Id);

            // Let's loop through the rows and add in information
            foreach (Row row in techSheet.Rows)
            {
                Cell techName = row.Cells.First(cell => cell.ColumnId == technicianMap["Technician Name"]);
                Cell techCertified = row.Cells.First(cell => cell.ColumnId == technicianMap["Certified Radios"]);
                Cell techLevel = row.Cells.First(cell => cell.ColumnId == technicianMap["Technician Level"]);
                Cell techEmail = row.Cells.First(cell => cell.ColumnId == technicianMap["Email"]);

                // Dyanmiclly Create Tab Pages with correct info on them
                UserControl newTechnicianControl = new TechnicianControl
                {
                    TechnicianLevel = techLevel.DisplayValue,
                    CertifiedRadios = techCertified.DisplayValue,
                    EmailAddress = techEmail.DisplayValue

                };
                TabPage techPage = new TabPage();
                techPage.Controls.Add(newTechnicianControl);
                techPage.Text = techName.DisplayValue.ToString();
                techPage.Name = "tech_"   techName.DisplayValue.ToLower();
                tcRepairs.TabPages.Add(techPage);
            }
        }

在創建程序中，我可以在定義 UserControl 時訪問它的屬性。我有一個計時器，可以每小時從智能表中提取一次更新資訊（請注意，我現在沒有提取我需要的所有資訊。我想在提取所有資訊之前先弄清楚我的問題）。在計時器滴答事件中，我想呼叫一個更新函式，該函式將更新每個 TabPage 中 UserControls 的標簽。

到目前為止，我已經為 UserControl 設定了三個屬性。

public string TechnicianLevel
        {
            get
            {
                return this.lblTechLevel.Text;
            }
            set
            {
                this.lblTechLevel.Text = value;
            }
        }

        public string CertifiedRadios
        {
            get
            {
                return this.lblCertifiedRadios.Text;
            }
            set
            {
                this.lblCertifiedRadios.Text = value;
            }
        }

        public string EmailAddress
        {
            get
            {
                return this.lblEmail.Text;
            }
            set
            {
                this.lblEmail.Text = value;
            }
        }

我能想到的唯一方法是洗掉除第一個 TabPage 之外的所有內容，然后重新添加它們。我覺得這種方法可行，但我覺得應該有更好的方法來更新 TabPage 中的 UserControl。

感謝@Jimi 和他們回圈遍歷TabPages. 下面現在正在更新UserControl TechnicianControl標簽。非常感謝！

private void UpdateTechnicianInfo()
        {
            // API identifies columns by ID, but it's more convenient to refer to column names
            Dictionary<string, long> columnMap = new Dictionary<string, long>();

            var techSheet = smartSheet.SheetResources.GetSheet(
                2589985581885316,
                null,
                null,
                null,
                null,
                null,
                null,
                null);

            // API identifies columns by ID, but it's more convenient to refer to column names
            Dictionary<string, long> technicianMap = new Dictionary<string, long>();

            // Build the column map for easier reference
            foreach (Column column in techSheet.Columns)
                technicianMap.Add(column.Title, (long)column.Id);

            // Lets loop through the rows and add in information
            foreach (Row row in techSheet.Rows)

                Cell techName = row.Cells.First(cell => cell.ColumnId == technicianMap["Technician Name"]);
                Cell techCertified = row.Cells.First(cell => cell.ColumnId == technicianMap["Certified Radios"]);
                Cell techLevel = row.Cells.First(cell => cell.ColumnId == technicianMap["Technician Level"]);
                Cell techEmail = row.Cells.First(cell => cell.ColumnId == technicianMap["Email"]);

                foreach (TabPage page in tcRepairs.TabPages)
                {
                    TechnicianControl technicianControl2 = page.Controls.OfType<TechnicianControl>().FirstOrDefault();
                    if (technicianControl2 != null && && page.Name == "tech_"   techName.DisplayValue.ToString())
                    {
                        technicianControl2.TechnicianLevel = techName.DisplayValue.ToString();
                    }
                }
            }            
        }
