这样的事情可能吗?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
我对这个概念不熟悉,并且觉得必须有一些我很遗憾的东西。
答案 0 :(得分:0)
没有进入原因,我最终做的是将计数器存储在会话变量中并从for循环退出sub,除非计数器等于数量。
然后我需要更新的for循环结束的所有内容(Labels,DropDownBoxes)我将自己的UpdateMode设置为自己的更新面板。
修改上面的伪代码:
Dim iCounter as Integer = Session("counter")
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
If iCounter <> iQuantity Then
Exit Sub
End If
Session("counter") = iCounter + 1
Next
//Everything else I needed to do with page controls wrapped
//in their own update panels
End Sub
也许不是'最佳实践',但它适用于我需要的东西。
