Hi Yogesh,
You should first check if the Sheet has an Autofilter applied first, and if so, then all you have to do is just create an autofilter on any range to turn it off. Something like:
Code:
Sub TurnOffAutofilter()
If Worksheets("Sheet1").AutoFilterMode = True Then _
Worksheets("Sheet1").Range("A1").AutoFilter
End Sub
Hope this helps :)
