我有GridView一个表单，即使Visible已True在属性窗口中设置为，它在浏览器中也不可见。更重要的是，我有以下代码可以使数据在 的列中可见GridView，但似乎对我没有任何作用。如果有人可以帮助我，我会很高兴。

Sub showgrid()
     Try
         ds.Clear()
         ada = New SqlDataAdapter("Select SubjectCode'Subject Code',SubjectName'Subject Name',SubjectType'Subject Type',UserId'User Id',Password from ProgramDetails.Subjects", cn)
         ada.Fill(ds, "ProgramDetails.Subjects")
         cmd = New SqlCommand("Select SubjectCode'Subject Code',SubjectName'Subject Name',SubjectType'Subject Type',UserId'User Id',Password from ProgramDetails.Subjects", cn)
         ada.SelectCommand = cmd
         ada.Fill(ds)
         GridView1.DataSource = ds.Tables(0)
     Catch ex As Exception
     End Try
End Sub

似乎您缺少DataBind().GridView

GridView1.DataSource = ds.Tables(0)
GridView1.DataBind()   // Add this
