Question

我能够正确访问网格中的每个列/行组合，第1列除外。它始终返回空白。以下是我尝试的4种不同方式，它们都运行，但都返回空白。

def a():
    result = b()
    return result

a()  # Call `a` before `b` has been defined.

def b():
    return 'foo'

所以我想获取列用户ID

protected void userListGrid_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "Display") //switch to update user mode
            {

                int rowIndex = Convert.ToInt32(e.CommandArgument);

                string Username = userListGrid.Rows[rowIndex].Cells[0].Text;
             // LinkButton Link = userListGrid.HeaderRow.Cells[0].Controls[0] as LinkButton;
             // string Username3 = Link.Text;
                string Username4 = userListGrid.Rows[rowIndex].Cells[0].Text.ToString();

                GridViewRow selectedRow = userListGrid.Rows[rowIndex];
                TableCell lastNameCell = selectedRow.Cells[0];
                string lastName = lastNameCell.Text; 


                List<CustomUserRecord> userRoleList = GetUserList(Username);
            }
        }

Answer 1

我最终这样做了。可能会得到帮助，但我没有意识到这是一个Linkbutton对不起所有，谢谢你的帮助。

 int rowIndex = Convert.ToInt32(e.CommandArgument);
 LinkButton Link = (LinkButton)userListGrid.Rows[rowIndex].Cells[0].Controls[0] ;
                string Username = Link.Text;

无法在Gridview中检索列[0]
