Navigation Code through records of a database

I have created a next button with this code to lead me through the records of the database:

VB

Protected Sub btnNext_Click(sender As Object, e As EventArgs) Handles btnNext.Click
       If (inc <> (MaxRows - 1)) Then

           inc = inc + 1

           Next()

       End If
   End Sub

where

VB

MaxRows = dst.Tables("TableName").Rows.Count

Private Sub Next()
txt_kodi.Value = dst.Tables("TableName").Rows(inc).Item(1)
       txt_pershkrimi.Valuedst.Tables("TableName").Rows(inc).Item(1)

When I click the next button it always save the first value I give to variable inc.
so it always leads me to the second row and that's all. I can't move to the third or the fourth.

If this is Web based, then yes, that is what I would expect - your variables are not preserved while the page is displayed, they are re-created each time as a Page Load event occurs when the user causes a post-back.

If you want to keep a value and increment it, then you either need to keep it on the page (as a visible of hidden control) or save it in the Session and retrieve it each time you wish to move on to the next record.

If this isn't web based, then you need to provide more information as to what else affects the value of inc
