The code looks like, foreach (listItem) { BindingSource.Add(listItem); } System.IndexOutOfRangeException: Index 0 does not have a value. .Value.ToString().Contains("Off")) Also another thing I find is the errors seem to happen more frequently when I'm clicking around on my datagridview. I'm not sure if that has anything to do with the problem or not.

As far as I understand, you don't have to populate BindingSource, you just have to populate the list it's bound to. That's the whole idea of 

Using hard-coded index values to manipulate an array is likely to throw an exception if the index value is incorrect or invalid, or if the size of the array being manipulation is unexpected. To prevent an operation from throwing an IndexOutOfRangeException exception, you can do the following:

I have a situation where I have a databound datagridview and if you try to scroll to the bottom about half way there it generates a System.IndexOutOfRangeException. However if you click on one of the header columns, causing a sort to occur, before you try to scroll all is well. 20120919,192131.61 [T9] DataGridView->Error(System.IndexOutOfRangeException): Index 2 does not have a value. at System.Windows.Forms.CurrencyManager.get_Item(Int32 index) at System.Windows.Forms.DataGridView.DataGridViewDataConnection.GetError(Int32 rowIndex) Select all Open in new window. The "Index" value is usually different between data reloads. where '5' is the index of the totals row. I found this question, which is essentially the same, except that the accepted answer is to either: 1) Not use an underlying list, which I must do, or 2) Delete from the grid instead of from the list. However, if I start without an initial xml, adding items is not a problem. But when I delete the last remaining item in the dgv, I get the following exception at the last line of Main() Index out of range Exception: {"Index -1 does not have a value."} Stack Trace Make sure that the maximum index on a list is less than the list size. The maximum index on a list must be less than the list size. Make sure the index is not a negative number. This exception will be thrown if the index is less than zero.
