Table sorting

Hi,

 

I have a table of a search results with a rowSelection="single".

I managed to preselect the first row in the table initially during getting the results. then i enabled the sort for most of the column using

<tr:column sortable="true" sortProperty="propertyname"

 

is there is a way i could always preselect the first row even after sorting by any of the sortable columns.

 

Thanks in advance.
