Enable/Disable <asp:HyperLinkField

[pargat.singh]

I am using <asp:HyperLinkField in gridview as below which is working
fine.

<asp:HyperLinkField HeaderText="Process"
Target="_blank" DataTextFormatString="Process me"
DataTextField="doc_name" DataNavigateUrlFields="doc_name"
DataNavigateUrlFormatString ="~/aaaa.aspx?path={0}" />

Currently it is displaying "Process Me" for all row and opening new
window.But i have some records which are already processed and for
those record i want to display Processed and i don't want to open the
new window.

Can anyone please show me how can i do that?

Thanks in advance.
