RESPONSE.WRITE和ASP.NET控件 [英] Response.write and ASP.NET controls

问题描述

请参阅下面的code：

Please see the code below:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        Response.Write("<table><tr><td>some text</td></tr></table>")
        Response.Flush()
        Threading.Thread.Sleep(3000)
        Response.Write("<table><tr><td>some text</td></tr></table>")
        Response.Flush()
        Threading.Thread.Sleep(3000)
        Response.Write("<table><tr><td>some text</td></tr></table>")
        Response.Flush()
        Threading.Thread.Sleep(3000)
        Response.Write("<table><tr><td>some text</td></tr></table>")
        Response.Flush()
        Threading.Thread.Sleep(3000)
    End Sub

的code工程，我期望即产生一个HTML表格并写入到屏幕上，然后在三秒钟后，产生另一个表，并加入到画面等。

The code works as I would expect i.e. a HTML table is generated and written to the screen, then after three seconds another table is generated and added to the screen etc.

我有一个网页动态地将表中的x个（的http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.table%28v=vs.110%29.aspx) 。到网页然而，Response.Flush似乎并没有工作，我已经创建了下面的简单code来解释这个问题：

I have a webpage that dynamically adds x number of tables (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.table%28v=vs.110%29.aspx) to a webpage. However, Response.Flush does not seem to work. I have created the simple code below to explain the problem:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        Dim Table1 As New Table
        Dim r As New TableRow()
        Dim c As New TableCell()
        c.Text = "Test 1"
        r.Cells.Add(c)
        Table1.Rows.Add(r)
        Response.Flush()
        Threading.Thread.Sleep(3000)

        Dim Table2 As New Table
        Dim r2 As New TableRow()
        Dim c2 As New TableCell()
        c.Text = "Test 2"
        r.Cells.Add(c)
        Table1.Rows.Add(r)
    End Sub

是否有可能刷新表1到客户端，然后等待几秒钟，然后冲水表2或你有写一个字符串RESPONSE.WRITE？

Is it possible to flush table1 to the client, then wait a few seconds then flush table2 or do you have to write a string to response.write?

推荐答案

要使用 Response.Flush 以这种方式，你需要输出所有的HTML code自己使用的Response.Write 。

To use Response.Flush in that way you need to output all the HTML code yourself using Response.Write.

您不能使用网络的控制，因为它们没有渲染，直到页面完成。该网站只控制存在的对象，直到那里的整个页面呈现为HTML code，然后发送给浏览器的 Page_Render 阶段。

You can't use web controls as they are not rendered until the page is complete. The web controls only exist as objects until the Page_Render stage where the entire page is rendered as HTML code and then sent to the browser.
