How to get Namespace of property metadata

Hi,

I am showing all the property metadata in the drop down.

My requirement is to fetch all the allowed values for the seleted metadata property from drop down.

Could anybody tell me how to get the namespace of the seleted property?I have Property ID and Unique ID of this property. Are these help to get the namespace?

I have already written the code to fetch the allowed value with one hard coded namespace.

I'm unable to retrieve the namespace of the seleted property.

Can anybody send the piece to code for it.

Thanks,

Vikas
