Problem with Nested Datagrid (WDK)

ro3er

Hi,

I need to nest a datagrid of checkboxes generated dynamically within another datagrid. The following is my code:

//jsp

<dmf:panel name="pnlSubTask">
        <table width="100%">
            <tr>               
                <td width="52%">   
                <dmf:datagrid name='parentGrid' cellspacing='1' cellpadding='2' bordersize='0' paged='true' pagesize='5'>
                                    
                      <!-- databound controls -->
                     <dmf:datagridRow >
                       
                        <!-- celllist defines the order and which fields to display from the query -->
                        <dmf:celllist fields='tel'>
                          
                           <!-- field specific cell template -->
                           <dmf:celltemplate field='tel'>
                                <td>
                                 
                                      <!-- generate checkboxes for template -->
                                      <dmf:datagrid name='childGrid' cellspacing='1' cellpadding='2' bordersize='0'>                                     
                                      <!-- databound controls -->
                                     <dmf:datagridRow >
                                       
                                        <!-- celllist defines the order and which fields to display from the query -->
                                        <dmf:celllist fields='object_name'>
                                          
                                           <!-- field specific cell template -->
                                           <dmf:celltemplate field='object_name'>
                                                   <td>
                                                 <dmf:label name="lblTemplate" style="font-size:12pt" datafield='CURRENT'/>                      
                                               
                                              </td>
                                              <td>
                                                 <dmf:checkbox name="chkTemplate" style="font-size:12pt" datafield='CURRENT'>
                                                     <dmf:argument name="objectId" datafield="r_object_id"/>
                                                 </dmf:checkbox>
                                              </td>
                                           </dmf:celltemplate>
                                          
                                           <!-- generic cell template (matches ALL remaining fields) -->
                                           <dmf:celltemplate>
                                              <td>
                                                <dmf:label datafield='CURRENT'/>
                                              </td>
                                           </dmf:celltemplate>
                                          
                                        </dmf:celllist>
                                     </dmf:datagridRow>                                             
                                  </dmf:datagrid>                 
                                     
                              </td>
                              <td>
                                      <dmf:button label="Submit" name="btnSubmit" style="font-size:12pt" onclick=""/>                                   
                              </td>
                           </dmf:celltemplate>
                          
                           <!-- generic cell template (matches ALL remaining fields) -->
                           <dmf:celltemplate>
                              <td>
                                <dmf:label datafield='CURRENT'/>
                              </td>
                           </dmf:celltemplate>
                          
                        </dmf:celllist>
                     </dmf:datagridRow>                                        
                  </dmf:datagrid>
                <br />
                </td>
            </tr>
        </table>
    </dmf:panel>

---------------------------------------------------------------------------------------------------

        //at onRender
        parentGrid  = (Datagrid) getControl("parentGrid", Datagrid.class);
        parentGrid.getDataProvider().clearResults();
        parentGrid.getDataProvider().setDfSession(getDfSession());
        parentGrid.getDataProvider().setQuery("dql to produce 5 rows");
        parentGrid.getDataProvider().initBind();
       
        childGrid  = (Datagrid) getControl("childGrid", Datagrid.class);
        childGrid.getDataProvider().clearResults();
        childGrid.getDataProvider().setDfSession(getDfSession());
        childGrid.getDataProvider().setQuery("dql to produce another 3 rows");
        childGrid.getDataProvider().initBind();

Somehow, the checkboxes are only displayed for the 1st row of the parent datagrid and not the others. Am I missing something here?

I also need to retrieve the values of the checkboxes within the datagrid when the submit button is clicked. How should I retrieve this value?

Thanks in advance.
