내 ASPXGridview, DetailRow보기 안에 텍스트 상자와 단추가 있습니다. 그래서 확장되면 텍스트를 입력하고 버튼을 클릭하고 서버 측에서 텍스트 상자의 값을 가져와야합니다.단추를 클릭하면 ASPXGridview에 중첩 된 컨트롤을 찾는 방법
여기 내 코드입니다. 문제는 포스트 백에서 텍스트 값을 잃어 버리는 것입니다. 그래서 텍스트 상자에 ASPxGridView 그것은 쉽게로 그래서 내가 그 방법을 사용하는 것이 좋습니다 그것으로 내장 된 콜백을 가지고

for (int i = 0; i < grid.VisibleRowCount; i++)
{
var txtDescription = (ASPxMemo)grid.FindDetailRowTemplateControl(i, "txtDescription");

{
var text = txtDescription.Text;
