I'm trying to store values in ViewState via a name I'm constructing dynamically. Following is the code I'm using to store values in ViewState:

    strTmpVar = "PageKey" & CStr(intCounter)
    ViewState(""" & strTmpVar & """) = colArrayList(tmpPage).PageNumber

I'm convinced that the way I'm constructing the name of the ViewState item is not working the way I had thought it would. When I retrieve the ViewState items I get the value 25 for all items.

Code used to retrieve values from ViewState:

    strTmpVar = "PageKey" & CStr(intCounter)
    intPageNum = CInt(ViewState(""" & strTmpVar & """))

Also I'm storing the name/value pairs in ViewState during the Page_Load when not a PostBack and retrieving the name/value pairs in Page_Load during a PostBack.

Is it possible to do what I'm trying to do and if so does anyone know the correct way to do it.

Thanks

.NET has built in a key/value method for the ViewState functionality. You [u]must</u> use this methodolgy, or you are going to be writing buggy code till midnight!
Values can be extracted from viewstate in exactly the same way, too.
I forget the syntax, but it is like: ViewState.Add("PageKey", strTmpVar)

I finally resolved the problem I was having. I did not fully explain why I was trying to generate dynamic name / value pairs. I am loading an object into a arrayList and needed to store the ArrayList in ViewState. I was convinced that I needed to unload all of the object's fields from the arrayList.

The answer was so easy I almost couldn't believe it.
1. Construct the Class as Serializable

    <Serializable()> Public Class myClass
    .
    .
    End Class

2. Store the arrayList like any other variable

    ViewState("myArrayList") = myArrayList

3. Retrieve the ArrayList from ViewState:

    myArrayList = New ArrayList
    myArrayList = CType(ViewState("myArrayList"), ArrayList)

Bingo, it was that simple.

Yeah, .NET has really made a lot of things unbelievably easy!
