如何在Windows窗體中使用自定義控件？

0

一旦你創建自定義的控制和編譯它應該在你的工具箱中顯示標題關聯到你的項目名稱下的項目。只需將它拖到您的表單就像您任何其他控制。

自定義控件的目的是封裝更復雜的功能並反覆重用。例如。如果您想使用單獨的NumericUpDown控件輸入100個三維座標，這需要很多工作來設置300個控件並將它們映射到數據對象的各個屬性。相反，您可以創建一個由3個NumericUpDown控件組成的自定義控件，這些控件可以直接綁定到Point3D對象。

如何使用我的程序，這些控制。 ...你能提供我示例代碼.....如何使用？ – Harini

創建TableLayout面板的形式，並與3個標籤所有的銀行詳細信息添加到列表中創建用戶控件，它們與foreach循環

private void YourForm_Load(object sender, EventArgs e) 
     {   
          var uc = new CustomControl(); 
       foreach (var detail in CheckDetails) 
        {      

          var uc = new CustomControl(); 

          uc.lblBankName.Text=detail.BankName; 
          uc.lblLowerLimit.Text=detail.LLimit; 
          uc.lblHigherLimit.Text=detail.HLimit; 
          var temp = tbl_BankDtls.RowStyles[tbl_BankDtls.RowCount - 1]; 
          tbl_BankDtls.RowCount++; 
          tbl_BankDtls.RowStyles.Add(new RowStyle(SizeType.Absolute, 35));        
          tbl_BankDtls.Controls.Add(uc, 0,0); 
          this.Height += 40; 
          this.MinimumSize = new Size(this.Width, this.Height); 
        } 
     }

是第三方控制....如果有辦法，我在那裏會得到自定義控件參考文件....什麼是命名空間......因爲它拋出錯誤... – Harini

沒有它不是一個第三方控制它只是一個用戶控件，您可以添加的，右擊項目（解決方案資源管理器） - >添加 - >用戶控件設計這是您的要求，這與上面的代碼片斷動態地添加到您的主要形式 –

這3個標籤控件和表layoutpanel必須在自定義控件或Windows窗體中？ – Harini
