Can't retrieve values in Hashtable

I am capturing the client path for upload files and storing them in a Hashtable from within the btn_UploadFile event.

VB Code:

'i is just a counter
'Add upload path to hashtable
strUploadPath.Add(attachmentFile.PostedFile.FileName.ToString, i)

In the btn_Submit click event I am trying to iterate through the Hashtable and grab the key/value pairs, but for some reason it isn't returning anything?? and I don't know why???

VB Code:

For each de in strUploadPath
   Response.Write("Key: " & de.Key) 
   Response.Write("<BR>")
   Response.Write("Value: " & de.Value)
Next

I don't know why it won't retrieve the values??? I have declared both variables in the General Declarations section, so they should be avaliable to any procedure.

Dim strUploadPath As New Hashtable
Dim de As DictionaryEntry

Does anyone know why I wouldn't be able to retrieve these values from the Hashtable???

***EDIT***
If I have it all in the same sub it works, but I need it separated into 2 different subs.

Hi Memnoch.

As far as I now, when pushing the submit button, the page reloads, thus REdim'ing you variables.

Try this:

btn_UploadFile event

VB Code:

Dim strUploadPath As New Hashtable
 
strUploadPath.Add(attachmentFile.PostedFile.FileName.ToString, i)
 
Session("MyHash")=strUploadPath

btn_Submit click event

VB Code:

Dim strUploadPath As Hashtable = Session("MyHash")
Dim de As DictionaryEntry
 
For each de in strUploadPath
   Response.Write("Key: " & de.Key) 
   Response.Write("<BR>")
   Response.Write("Value: " & de.Value)
Next

I have not tested this, but I think it just might work.

I figured it out...I need to write the Hashtable values to the ViewState.
