Exception on Form restore

[Scott Adams]

I am experiencing an odd issue when my form is minimized. Upon activation,
my form refreshes some data within a DataGrid control. No exception is
thrown until the form is minimized, then restored from the task bar. Upon
restore, an exception is thrown in the Activated event. The exception is as
follows:

System.Argument Exception: '0' is not a valid value for 'value'. 'value'
should be between 'minimum' and 'maximum'.
at System.Windows. Forms.ScrollBar .set_Value(Int3 2 value)
at System.Windows. Forms.DataGrid. SetDataGridTabl e(DataGridTable Style
newTable, Boolean forceColumnCrea tion)
at System.Windows. Forms.DataGrid. TableStylesColl ectionChanged(O bject
sender, CollectionChang eEventArgs ccea)
at
System.Windows. Forms.GridTable StylesCollectio n.OnCollectionC hanged(Collecti o
nChangeEventArg s ccevent)
at System.Windows. Forms.GridTable StylesCollectio n.Clear()
at MyProject.frmMy Form.FormatGrid ()
at MyProject.frmMy Form.MyForm_Act ivated()

The exception occurs on a line of code that simply clears all TableStyles
from the DataGrid object (frmMyForm.MyDa taGrid.TableSty les.Clear). Any ideas
as to why this only occurs when the form is restored from being
minimized?
