I think the error is thrown because the doc is changed.

Rewrite

' This is the Line2
    doc.getElementById("ContentPlaceHolder1_GridView1_chkboxSelectAll").Click
    'Wait 3 seconds till it selects all the checkboxes
    Application.Wait DateAdd("s", 3, Now)

as

' This is the Line2 
    application.wait Application.Wait DateAdd("s", 1, Now)
    set doc = IE.document
    doc.getElementById("ContentPlaceHolder1_GridView1_chkboxSelectAll").Click
    'Wait 3 seconds till it selects all the checkboxes
    Application.Wait DateAdd("s", 3, Now)

maybe helpful.
