UltraTree 'Parameter not valid' error
posted

Hi,

We are currently using an UltraTree in an application. We have a customer (that I believe is always using a remote desktop connection) that randomly experiences a "Parameter not valid" error.

Here is the stack trace:

System.ArgumentException: Parameter is not valid.
   at System.Drawing.Image.get_Width()
   at System.Drawing.Image.get_Size()
   at Infragistics.Win.EditorWithTextUIElement.GetImageSize(Image img, Size& imageSize)

   at Infragistics.Win.UIElement.VerifyChildElements(ControlUIElementBase controlElement, Boolean recursive)

   at System.Windows.Forms.Control.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.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

To be honest, I haven't gotten a good read on what is actually causing the error, was hoping that something would jump out given the stack trace.

I believe the following is the version of Infragistics being referenced.

11.2.20112.2050


Thanks in advance!
