主题：求助：按钮代码

老师好：这个代码怎样改成按钮，在按钮中应该怎样写呢？多谢。

If e.DataCol.name = "审核" Then
Dim pr As DataRow = e.DataRow.GetParentRow("订单")
If pr IsNot Nothing Then
Dim crs As List(of DataRow) = pr.GetChildRows("订单明细")
Dim cnt As Integer
For Each cr As DataRow In crs
If cr("审核") = True
cnt = cnt + 1
End If
Next
pr("审核") = (crs.Count = cnt)
End If
End If
