Hello,

a few users of one of our customers currently experience the following issue when our program calls Infragistics.Win.UltraWinGrid.UltraGridLayout.LoadFromXml(Stream stream, PropertyCategories propertyCategories).

The stream is a memory stream and propertyCategories is set to PropertyCategories.All.

This results in a System.Reflection.TargetInvocationException.

The strange thing about this is, that no matter the source of the XML (in this case it is actually created in memory and loaded from anywhere) this fails. I have compared the XML with the XML on a machine where it worked and did not find any significant differences.

This issue on comes up on very few specific computers and not anywhere else.

We have checked the GAC and the folder our software has been deployed in and there are no anomalies either.

The users culture is US English.

Has anybody else experienced a similar error?

Here is the call stack

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Input string was not in a correct format.
