上按一下按钮递增变量在ASP.net [英] Incrementing variables in ASP.net on button click

问题描述

我是新来asp.net。我创建使用VB.net一个ASP.net网站。因此，这里是我的问题。

I am new to asp.net. I am creating a ASP.net website using VB.net. So here's my problem

Dim myCounter as Integer = 0

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles Button1.Click

        myCounter =  myCounter + 1

        Label1.Text = myCounter.ToString()

end Sub

正如预期的那样，我总是得到标签文本为0每次点击的按钮。如何创建全局变量并增加它。

As expected I always get Label Text as 0 each time click the button. How to I create global variable and increment it.

推荐答案

@Rex M的使用视图状态的建议是不错的。

@Rex M's suggestion for using Viewstate is good.

如果计数器不敏感信息或东西你担心与他人篡改，这里有一个更简单的想法：

If the counter is not sensitive information or something you're worried about someone tampering with., here's an easier idea:

您也可以使用＆LT; ASP：HiddenField＆GT; 并存储该值在那里。然后，它会回发之间持续存在，你可以每次增加它。

You can also use an <asp:HiddenField> and store the value there. Then it will persist between postbacks and you can increment it each time..
