Make image header a link

Hello,

I have a grid I’m creating and I’m using enableHeaderImages to insert custom images in the header fields. My current issue is I’d like to have clicks to the image header also load an iframe above the grid as well as sorting.

Is there a way to do this? I suppose I could also add a button on a subheader below the image header but is there a preferred way out of the two? If so, which?

You can use any HTML in grid header instead of text.
Look a this tutorial. http://docs.dhtmlx.com/doku.php?id=dhtmlxgrid:header_extra#plain_html_in_headers_footers
Something about it

setHeader("<a href='some.html'><img src='some.gif' /></a>,B,C")
