Hi pramodpogal,

I don't know the release version of the xamDataGrid component that you are using. It's possible the issue to 
result from  the used version.
In answer to your doubt - "If AutoGenerateFields property = "False" and i am adding the fields in xaml."
you should take into account the following in relation to the AutoGenerateFields property:
 
When AutoGenerateFields="False" the control seeks to find the FieldLayout that corresponds to the Type of the Data Item.
    
We could have two possibilities:

-  we can have a FieldLayout defining the Fields(columns) contained in a DataRecord from the DataSource(the same as the
   Fields(columns));
     
   When a DataRecord is created, the FieldLayouts collection is searched for an existing FieldLayout whose Fields
   match the DataItem's properties. If a FieldLayout is found, it is associated with the DataRecord.
      
   In this case the Headers(Fields) will be visible even if the DataSource is empty.

-  we can have a FieldLayout defining the Fields(columns) that are not contained in a  DataRecord from the DataSource;
     
   When a DataRecord is created, the FieldLayouts collection is searched for an existing FieldLayout whose Fields
   match the DataItem's properties. If it is not found, a new FieldLayout is created.
   When a new FieldLayout is created, the FieldLayoutInitializing and FieldLayoutInitialized events are raised.

   In this case  the Headers(Fields) won't be visible.        

Best Regards,

Hi Yanko

Thank You very much for your reply and sample.

I have a doubt. If AutoGenerateFields property = "False" and i am adding the fields in xaml.

Then the same problem is persisting. Please help me out in this also.

Thanks,

Pramod
