나는 동적 gridview를 가지고 있고 ... 네 개의 열이 있습니다. 원하는 것은 마지막 열 "amount paid"에서 gridview의 textbox 값에 액세스하여 총 합계 값을 표시하는 것입니다 label.Below는 내가 시도한 코드입니다. 누군가 이걸 어떻게하는지 알려 줄 수 있습니까?gridview에서 textbox 값에 액세스

레이블은 GridView 뒤/아래에 정의됩니다. 모든 값을 합산하려고합니까, 아니면 각 행의 합계를 표시할까요? – CodeCanuck
안녕하세요, 명확하게 문제를 지정하십시오. gridview에 총 금액이라는 열이 없습니다. gridview에서 총 열 값을 표시하려면, 또는 모든 이벤트에서 텍스트 상자에 액세스하려고합니다. –
예 지불 한 금액의 모든 금액의 합계를 표시하고 싶습니다. – user2605927
