I have a checkbox in the first column of my listview and in my subclass I handle the OnDoubleClick to automatically check/uncheck this checkbox, also when clicking the 1st column header, I have code to check/uncheck all items, but as I reported before, this may be fighting with the sorting which cannot be disabled yet. I catch this on a form when double clicking the form's caption to maximize it. I need to put more time (which I don't have ) to try to duplicate this more clearly. Edhy Rijo

E Group: StrataFrame Users Posts: 2.4K, Visits: 23K	On some situation, when a form with StrataListView is double clicked on the form's caption to maximize it, an exception will be trigger by the StartaListViewItemCollection.Sort() method. Any ideas on how this could be trapped? also, any news on upcoming updates for the StrataListView? Here is the exception: InvalidOperationException Failed to compare two elements in the array. ArgumentOutOfRangeException Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Source : mscorlib Stack Trace: at System.ThrowHelper.ThrowArgumentOutOfRangeException() at System.Collections.Generic.List`1.get_Item(Int32 index) at MicroFour.StrataFrame.UI.Rendering.Sorting.StrataListViewSorter.System.Collections.IComparer.Compare(Object x, Object y) at System.Array.SorterObjectArray.SwapIfGreaterWithItems(Int32 a, Int32 b) at System.Array.SorterObjectArray.QuickSort(Int32 left, Int32 right) at System.Array.Sort(Array keys, Array items, Int32 index, Int32 length, IComparer comparer) at System.Collections.ArrayList.Sort(Int32 index, Int32 count, IComparer comparer) at System.Collections.ArrayList.Sort(IComparer comparer) at MicroFour.StrataFrame.UI.Collections.StrataListViewItemCollection.Sort() at MicroFour.StrataFrame.UI.Windows.Forms.StrataListView.ManageMouseUp_Columns(MouseEventArgs e) at MicroFour.StrataFrame.UI.Windows.Forms.StrataListView.ManageMouseUp(MouseEventArgs e) at MicroFour.StrataFrame.UI.Windows.Forms.StrataListView.OnMouseUp(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.UserControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativewindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativewindow.WndProc(Message& m) at System.Windows.Forms.Nativewindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(IntPtr dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at MicroFour.StrataFrame.Application.StrataFrameApplication.RunApplication() Thanks!
