Tooltip for Datagrid Column Header

Question

Greetings!
I used the example here - http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2009/12/14/Add-a-Zoom-button-to-a-DataGrid.aspx - to set up a datagrid to display my results.  This works great, but I would like to change the tooltip that displays when you hover over the column name.  In the example, when you hover over the magnifying glass in the column header, a plus sign (+) appears.  I would like to change this to something more meaningful - like "Zoom."  I have searched and searched, but can not find where this is set.  Does anyone know how I can change it?
Thanks!

YES!! That was it.  I knew it had to be something simple.  One of the drawbacks of copying and pasting code from examples...I didn't even see that in there.  Thank you!!!

well, in the posted example, if you look at the source code, down in the HTML section look at your table tag. specifically this line:

the tag... change the '+' in the alt attribute to 'zoom' and that should do it.
