Example

The following example lets you update a database by using a cfgrid tag to add and delete entire records or to update the data in individual cells. The cfgridupdate tag processes the data from the submitted form and updates the database.

<!--- If the gridEntered form field exists, the form was submitted. Perform gridupdate. ---> 
<cfif IsDefined("form.gridEntered") is True> 
    <cfgridupdate grid = "FirstGrid" dataSource = "cfdocexamples" Keyonly="true" 
        tableName = "CourseList"> 
    </cfif> 
 
<!--- Query the database to fill up the grid. ---> 
<cfquery name = "GetCourses" dataSource = "cfdocexamples"> 
    SELECT Course_ID, Dept_ID, CorNumber, CorName, CorLevel, CorDesc 
    FROM CourseList 
    ORDER by Dept_ID ASC, CorNumber ASC 
</cfquery>
