<table style="font:12px/19px Tahoma, 'Microsoft Yahei';color:#444444;text-transform:none;text-indent:0px;letter-spacing:normal;word-spacing:0px;border-collapse:collapse;table-layout:fixed;border-spacing:0px;"> 
 <tbody> 
  <tr> 
   <td> 
    <div> 
     <div>
       &nbsp; 
     </div> 
     <div style="font-size:14px;min-height:380px;"> 
      <div> 
       <div> 
        <div style="font-family:georgia, serif;font-size:16px;"> 
         <p>Use the&nbsp;SearchClear()&nbsp;method which is part of the Field class to clear search values on a particular search key field. This is how you can<em style="font-style:italic;font-weight:normal;">reset</em>&nbsp;search parameters specified by a user when they press the&nbsp;<em style="font-style:italic;font-weight:normal;">Return to Search</em>&nbsp;button.</p> 
         <p>You can call this using the shortcut notation:</p> 
         <div style="border:1px dashed #dddddd;font-family:'Andale Mono', 'Courier New', Courier, monospace;font-size:10pt;"> 
          <code style="font-family:'Andale Mono', 'Courier New', Courier, monospace;font-style:normal;font-weight:normal;">RECORD.FIELD.SearchClear();</code> 
         </div> 
         <p>Or you can declare a field class and then call the method.</p> 
         <p>Put this code in the&nbsp;SearchInit&nbsp;event.</p> 
         <p>If you are clearing a number of fields, I recommend creating a simple function (e.g.&nbsp;ResetSearch) in&nbsp;FieldFormula&nbsp;and calling that function rather than putting a single line of code in the&nbsp;SearchInit&nbsp;event for each field you are clearing. Just makes maintenance a little bit simpler as you only need one function and one call.</p> 
        </div> 
       </div> 
      </div> 
     </div> 
    </div> </td> 
  </tr> 
 </tbody> 
</table>
