Dear Friend,

Try this,

For j As Integer = 0 To menuItemMaster.ChildItems.Count - 1  ==> 6 count will be there
               If menuItemMaster.ChildItems(j).Value = "0" Then
                   menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems[j].Item(0))
               End If
               If menuItemMaster.ChildItems(j).Value = "2" Then
                   menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems[j].Item(2))
               End If
               If menuItemMaster.ChildItems(j).Value = "3" Then
                   menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems[j].Item(3))
               End If
If menuItemMaster.ChildItems(j).Value = "4" Then
                   menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems[j].Item(4))  ==> Error : out of index range
               End If
           Next

I have changed
menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems.Item(3)) to menuItemMaster.ChildItems.Remove(menuItemMaster.ChildItems[j].Item(3))

Hope this will help you out

Hi,

As per my understanding, in your code you are using a for loop, which loops for 6 times say.

In your first loop you are removing few child items and this repeats for 6 times and you refer the items that are already removed.So you get a index out of range exception.

Instead you can loop through and remove each item at once if its irrespective of value.
Hope this helps.
