我在绑定过后，再点击按钮来读取数据源的列值，像以下代码，但发现row.DataItem为空，导致拿出来的brand_id 也是空的。我发现repeater用这样的方式就可以拿出来，请指教。
For Each row As GridViewRow In grvApproveList.Rows
dim brand_id as string = DataBinder.Eval(row.DataItem, "brand_id")
Next

If e.Row.RowType = DataControlRowType.Footer Then
' Get the number of items in the Rows collection.
Dim count AsInteger= AuthorsGridView.Rows.Count
' If the GridView control contains any records, display
' the last name of each author in the GridView control.
If count >0Then
Message.Text ="The authors are:<br>"
Dim row As GridViewRow
ForEach row In AuthorsGridView.Rows
Message.Text &= row.Cells(0).Text &"<br>"
Next
EndIf
EndIf
End Sub

你用row.Cells(0).Text是吗？但如果我的要读取的这个列不显示出来呢？
