동적 테이블 내에서 동적 텍스트 상자를 처리하려면 어떻게해야합니까?

Question

같은 열의 텍스트 상자에서 값을 SUM (추가)하고 "계산"버튼을 클릭하여 텍스트 상자를 마지막 행에 표시합니다.
모든 텍스트 상자는 "표 만들기"버튼을 클릭하면 동적으로 생성됩니다.

나는이 텍스트 상자의 ID를 얻는 방법을 모르겠다.

Plz은에 unale 오전 읽는 동안 그것을 할 나를 올바른 방법을 제안한다.

Answer 1

이것은 유용한 기능 일 수 있습니다. Function source

public static Control FindControlRecursive(Control root, string id) 
    { 
     if (root.ID == id) 
     { 
      return root; 
     } 

     foreach (Control c in root.Controls) 
     { 
      Control t = FindControlRecursive(c, id); 
      if (t != null) 
      { 
       return t; 
      } 
     } 

     return null; 
    } 

그런 다음이 텍스트 상자를 반복하면됩니다.

for (int i = 0; i < tblRow; i++) 
     { 
      for (int j = 2; j <= 7; j++) 
      { 
       TextBox tb = FindControlRecursive(this, string.Format("txtBoxRow{0}Col{1}", i, j)); 
       switch(j) 
       { 
        case 2: 
         TotAmt += Convert.ToDouble(tb.Text); 
         break; 
        case 3: 
         break; 
        default: 
         Label1.Text = Convert.ToString("Value of J : " + j); 
       } 
      } 
     }
