cfgrid

Hi,

i have the search page and want to display the results on the the cfgrid.  Both form and cfgrid are on the same page.  When i first open the form.cfm page, i see all the results already display on the page.  This is not right, i only want the results to display when i search something and hit on the submit button.  Can you please help?

<!---my form.cfm--->

<cfparam name="variables.row_per_page_default" default="50">

<cfparam name="variables.row_per_page_list" default="15,30,50,75,100">

<cfform name="search" action="form.cfm" method="post" onsubmit ="ColdFusion.Grid.refresh('myGrid', false);">
<cfinput type="text" name="aNo_var" id="aNo_var">
<input class="button" type="submit" name="submit" value="Search" />

<!---diplay on the cfgrid--->

    <cfgrid
     format="html"
        name="grid01"
        width="700"
        sort=true
          bindOnLoad="true" 
      pagesize="#variables.row_per_page_default#"
         bind="cfc:cfc.searchA.cf_city({cfgridpage},{cfgridpagesize},
            {cfgridsortcolumn},{cfgridsortdirection},
            {aNo_var})">
        <cfgridcolumn name="aNo_var" width="100" display=true header="Name" />
      
    </cfgrid>

</cfform>
