NullReferenceException at Infragistics.Win.ValueList.ProcessSelectionChangeCommitted()
posted

Hello Team

I am facing below issue, type some alphabet in combobox cell type in UltraGrid after drop down popups with suitable values then select some thing from list.

System.NullReferenceException: Object reference not set to an instance of an object.
at Infragistics.Win.EditorWithCombo.Infragistics.Win.IValueListOwner.OnSelectionChangeCommitted()
at Infragistics.Win.ValueList.ProcessSelectionChangeCommitted()
at Infragistics.Win.ValueListDropDown.OnSelectionChangeCommitted()
at Infragistics.Win.ValueListDropDown.SelectItemByMouse(ValueListItem valueListItem)
at Infragistics.Win.ValueListDropDown.OnMouseUp(MouseEventArgs e)
at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
at System.Windows.Forms.Control.WndProc(Message& m)
at Infragistics.Win.ValueListDropDownUnsafe.WndProc(Message& message)

at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

This issue is only when we have items in dropdown which matches what we have entered in dropdown.

Thanks in advance.
