SPRadGrid and Managed Metadata Column

[Markus]

Dear all,

I encountered problems with the SPRAdGrid web part using managed metadata columns from SharePoint 2010.

What I did:
I created a list with a column of type "managed metadata".
The column refers to a term set and is included in my default list view.

Then, I added the SPRadGrid web part to my web part page.

The Problem:
When accessing the web part page, I get an error message "An unexpected error has occurred."

The SharePoint log lists the following information:
System.ArgumentException: Column 'Term$Resources:core,Language;' does not exist. It may have been deleted by another user.  /Lists/TaxonomyHiddenList    at Microsoft.SharePoint.SPFieldCollection.GetFieldByInternalName(String strName, Boolean bThrowException)     at Telerik.Ajax.SharePoint.FieldDataLookup..ctor(SPFieldLookup relatedField)     at Telerik.Ajax.SharePoint.SPFieldToFieldDataMapper.MakeFieldDataFromSPField(SPField field)     at Telerik.Ajax.SharePoint.SPFieldToFieldDataMapper.MapSPFieldToSPFieldData(SPField field)     at Telerik.Ajax.SharePoint.SPTableViewMapperBase.InitializeFields(SPViewDataProvider viewParser, SPView currentView, SPList currentList, List`1 fields)     at Telerik.Ajax.SharePoint.SPTableViewMapper.BuildGridColumns(SPView view, SPList list, GridTableView gridTab... 

As soon as I remove the managed metadata column from the view, everything works fine.

Some system information:
Telerik RadControls for SharePoint 11.1.413.0
SPRadGrid Web Part
Windows Server 2008 R2
SQL Server 2008 R2
SharePoint Server 2010
IE 9

My questions:
- does the SPRadGrid web part support the use of managed metadata columns at all?
- if yes, does anybody know the problem or maybe the solution?

TIA
Markus

Hello Markus,

Unfortunately, SPRadGrid does not support meta data columns. Our development team has this feature on its to-do list but as yet other priorities have pushed it somewhat in the back-ground. We will consider adding it for the Q2 release of the controls. 

Best wishes,

is this now supported in telerik rad grid to have managed metadat column?

Hi,

Indeed there is such support for Managed Metadata column included. It replies on the Managed Metadata service running and the availability of the Microsoft.SharePoint.Taxonomy assembly on the server.
The exception that Markus has received indicated that it is Term$Resources:core,Language; That is not a valid name for a grid column. You can try configuring the Metadata column with a name without special symbols like: commas, colons etc. to see if it will make a difference.
