Answer 1

Use proper page load waits after each .Navigate and .Click.

Also, you can wrap elements that are throwing errors, related to timings, in timed loops which attempt to set the object reference

Dim t As Date, ele As Object
Const MAX_WAIT_SEC As Long = 10

t = Timer
Do
    On Error Resume Next
    Set ele = doc.getElementById("ContentPlaceHolder1_GridView1_chkboxSelectAll")
    On Error GoTo 0
    If Timer - t > MAX_WAIT_SEC Then Exit Do
Loop While ele Is Nothing

If Not ele Is Nothing Then
    ele.Click
End If
