我有一個應用程序，有3個文本框，（用戶名，他們來自哪家公司，他們正在訪問誰）打印一個按鈕，並在屏幕上的鍵盤（顯示器是觸摸屏）。我有一切工作和運作...問題appendText在c＃
但是，一個不起作用的是當用戶指向已經鍵入的文本框中的前一個字符，「AppendText」（鍵盤）的按鈕做沒有開始輸入用戶指向的地方，但它在輸入內容的末尾繼續輸入。
這是因爲「AppendText」或其他問題，我在我的代碼？
我也試圖讓第一個文本框（Name_Box）被髮送到一個，然後將被拆分成兩個標籤（1，名字| 2，姓氏）現在我有它被髮送到一個標籤但我想分割它，所以第一個名字疊加在第二個名字的下一個表格中（打印出來）。
非常感謝。

'追加'的意思是'在最後'。沒有InsertText嗎？ –
