How to Utilize Session State to Hold and Add Values to an Arraylist?

[RLindahl]

Greetings,

What I am trying to do is take input from a webform's textbox and place this in an arraylist (on button click) that holds mutliple inputs. I have it working that viewstate holds the first item I select but if I choose a second it replaces the first instead of adds to it. Research I've done would suggest that I need to use a session state to hold the array list however, I'm not sure how to utilize this properly.

I'm not sure what is necessary to show but here is my storage button click event thus far (Language is VB):

Protected Sub StoreBtn_Click(sender As Object, e As System.EventArgs) Handles StoreBtn.Click
 
        Dim saveResult As String = txtResult.Text
 
        Dim elementCount As Integer = arraylistSave.Count
 
        If elementCount <= 9 Then
 
            arraylistSave.Add(saveResult)
        Else
            arraylistSave.Clear()
            arraylistSave.Add(saveResult)
 
        End If
End Sub
 

Any insights or direction would be greatly appreciated.

My Best,

RL
