cfgrid in coldfusion 7

It should work. Dump the query to verify whether there is any data going into the grid.

How do I know it should work? By testing your exact code with the cfdocexamples datasource that ships with ColdFusion. The following code gives me a Flash grid:

<cfquery name="getCourses" datasource="cfdocexamples">

select *

from courses

</cfquery>

<!--- <cfdump var="#getCourses#"> --->

<cfform>

   <cfgrid name = "FirstGrid" format="flash"

      height="320" width="580"

      font="Tahoma" fontsize="12"

      query = "getCourses">

   </cfgrid>

</cfform>
