Hey guys,

We are having an issue at a customer site with the Syncfusion GridGroupingControl. It is throwing an exception while trying to parse an XML string. Strangely enough it is only occurring for a couple of users, so we know that the XML is correct. I wrote some test code to reproduce the error as simple as possible. Both the code and the error are included below and the XML is attached, any help you guys can give would be appreciated.

Environment info:

Windows XP SP2
Visual Studio 2005
.NET Framework 2.0
Syncfusion 4.102


Code:

GridGroupingLookAndFeel gglaf = GridGroupingLookAndFeel.CreateFromXml(new StringReader(xml)); _gccTest.TableOptions.ShowRecordPreviewRow = gglaf.TableOptions.ShowRecordPreviewRow; _gccTest.Appearance = gglaf.Appearance;


Stack Trace:

System.InvalidOperationException: There is an error in XML document (10, 22). ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.FormatException: Input string was not in a correct format.

Hi Kevin,

Sorry for the delay getting back with you.

I am afraid that I was not able to reproduce the issue. I have created a simple sample to test this issue and it is available in the following link.
http://websamples.syncfusion.com/samples/Grid.Windows/40102/main.htm

Sample video link:
http://www.syncfusion.com/support/user/uploads/SampleVideo1_9c99b582.zip

You can pass either TextReader or XMLReader to CreateFromXml() method. Kindly let me know, are you passing StringReader directly to the CreateFromXML method. Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample or send us the reproducing steps so that we could sort out the cause of the issue and provide you a solution.

Regards,
Suba
