Help with incrementing variable

I am not sure what I am doing wrong...
I am trying to increment a variable but each time it will only increment once and then resets to 0

I have declared a variable in the class section of my codebehind.vb of my aspx page

public class webform1
...
dim i as integer
...

I have to buttons that trigger subs (fwd and back) which should increment the variable by 1 each time

sub goFwd()
....
i = i + 1
....
end sud

sub goBack()
...
i = i - 1
...

But no matter how many times I click the button to trigger goFwd, i always = 1, it doesnt seem to increment the value each time.

If any can understand what I mean here and can help me, it would be greatly appreciated.

If the coding is done properly it will work fine. Make sure the variable is declared globally and isnt being interfered with by another command.

Public I as integer

I += 1 or I -= 1

This could be your problem

I believe it is coded properly...here is what I've got, it still doesnt work

Public Class WebForm2

Inherits System.Web.UI.Page
Public i as integer

.....


Private sub Page_Load(.....) handles MyBase.load

response.write(i)

end sub


sub goFwd(......)

i += 1

response.write(i)

end sub

end class


everytime I click the button to trigger goFwd, I got a 01, the 0 from Page_Load and 1 from goFwd, it wont go to 2 or 3 or anything else, any ideas what I might be doing wrong? I know this is simple and everything looks fine to me but still wont work for some reason, Im sure im gonna kick myself when I find the solution....

Try putting Public Shared I as integer instead. Also double check and make sure you are not using (i) anywhere else. From what I can see, it should work fine. You could also create a function an pass the integer back and forth. Not recommended though.

I found what I was doing wrong..

Class member variables are not stored in the ViewState by default so each time the page loads or postbacks, a new instance of the class is created which kept intializing my i variable back to zero. So I had to use this in my Page Load event

if not IsNothing(Viewstate("i")) Then


i = Viewstate("i")


else


i = 0


Viewstate.Add("i", i)


End If


and then also call ViewState("i") = i after each time I changed the value.


Thank you much for taking the time to try to help me, happy programming!
