Subject RE: How to let a user click a column header to sort data in a table using struts?
Date Wed, 15 Jan 2003 14:02:33 GMT

<!--- DISPLAY TAG --->

<display:table width="100%" name="list" display="1"
decorator="some_class" >
  <display:column property="id" title="ID" decorator=" some_class " />
  <display:column property="name" decorator=" some_class " />
  <display:column property="type" decorator=" some_class " />
</display:table>

I've listed the decorator parameter on the tags because this will allow
you to either wrap objects to provide special links or you can assign a
decorator to each column where each column has it's own decorator:

Example:

Hope this helps

| Subject: RE: How to let a user click a column header to sort data in a
| table using struts?
| 
| I seek to use the tag < display:table > with an aim of offering the
| sorting
| by column header. I would wish to know if there is no disavantage to
use
| < display:table> rather than basic tag HTML.
| In the display library examples JSP source combine table tag and
| display:table tag. Why doesn't one use only display:table?
| The list of the display:table and display:column
| attributes are available in the display.tld file but is there an
| explanation
| in the form textual of these attributes ?the tld file is not detailed
and
| I
| have some difficulties to modify my JSP page to use <display:*> tags.
| 
| Can we combine < display:tag > with struts <logic:iterate> tag ?
| 
| How can I modify the following code to use <display:*> tags ?
| 
| <table width="100%" border="1" cellpadding="0" cellspacing="0"
| bordercolor="#FFFFFF">
| 
| <%-- Title for the columns of the table --%>
| <tr bgcolor="#FFCC00">
|     <th align=left width="13%"><bean:message key="label.id"/></th>
|     <th align=left width="5%"><bean:message  key="label.name"/></th>
|     <th align=left width="9%"><bean:message key="label.type"/></th>
| </tr>
| 
| <logic:iterate id="elements" name="list" type="myappli.myClass"
| offset="offset" length="length">
| <tr bgcolor="#EBEBEB">
|     <td bgcolor="#EBEBEB" width="13%">
| 	<html:link href="action.do">
|     	<bean:write name="elements" property="id"/>
|     	</html:link>
|     </td>
| 
|     <td bgcolor="#EBEBEB" width="5%">
| 	<bean:write name="elements" property="name"/>
|     </td>
| 
|     <td bgcolor="#EBEBEB" width="10%">
|       <html:checkbox name="elements" property="type" value="on"/>
|     </td>
| </tr>
| </logic:iterate>
| </table>
| 
| Least help would be appreciated.
| Thanks
| Sandra
