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.ControlNativeWindow.WndProc(Message& m)

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

Thanks in advance.

    Hello Siva,

    This is very similar to an issue which we encountered and have fixed in the latest service release. Please update your product to our latest service release and see if the issue persists.

    If it does persist, if you send us an isolated sample which reproduces the issue we could investigate the cause of the issue and work toward resolution.

    Please let me know if I can further assist you.
