want to get the row key from the extendedDataTable.

[jsfgeeks]

Hi all,

I am a newbie to the richfaces. I have an extendedDataTable to show and select some data from the database and to add to the other table. I am using calendar and checkbox inside the extendedDataTable. Now, what I want is that, if anyone changes the date or select the checkbox then I am calling the function of backbean like;

<rich:column width="150px" style="text-align: center" label="Last Date">
 <f:facet name="header">
 <h:outputText value="Last Date"/>
 </f:facet>
 <rich:calendar immediate="false" cellHeight="7" cellWidth="20" boundaryDatesMode="scroll" showWeeksBar="false" showHeader="false" inputSize="12" datePattern="dd/MM/yyyy" showFooter="false" jointPoint="top-right" direction="top-left" popup="true">
 <a4j:support immediate="true" action="#{backbean.method_of_backbean}"
 event="onchanged"/>
 </rich:calendar>
 </rich:column>

It's working fine (I mean it calls the backbean method). But I don't know how to get the row key and that changed value.

Any help regarding this will help me a lot.

Thanks in advance

Hi ilya_shaikovsky,

Thanks for your support. I have seen there, but as I told you I want a backbean code which can help me to get the data of that particular row. Actually I am trying but right now I just can get the row key.

If there is any other way available, then also you can tell me. And if possible, give me a sample code, so that I can better understand.

Thanks again,

Hi ilya_shaikovsky,

I again appreciate your help. I have seen there, but as a newbie, I am not able to get the thing. So now I am showing my code for the table. I mean what I have done till now.

The table(JSP):

<rich:extendedDataTable binding="#{assign_car.table_car_list}" value="#{assign_car.car_list}" var="row" id="table_car_list" style="left: 15px; top: 65px; position: absolute" onRowMouseOver="this.style.backgroundColor='#F1F1F1'" onRowMouseOut="this.style.backgroundColor='#FFFFFF'" width="650px" height="208px" sortMode="Ascending" rows="0">
 <f:facet name="header">
 <h:outputText value="Assign Car"/>
 </f:facet>

<rich:column id="car_sel" width="190px" style="text-align: center" label="Select Car">
 <f:facet name="header">
 <h:outputText value="Select Car" />
 </f:facet>
<h:selectBooleanCheckbox binding="#{assign_car.cb_select_car}" immediate="false" id="cb_select_topic">
 <a4j:support event="onchange" immediate="true" action="#{assign_car.value_change_car_selection_cb}">
 </a4j:support>
 </h:selectBooleanCheckbox>
</rich:column>
 <rich:column id="car_name" sortBy="#{row.car}" width="220px" label="Topic">
 <f:facet name="header">
 <h:outputText value="Car Name" />
 </f:facet>
 <h:outputText id="col_car_name" value="#{row.car}"/>
 </rich:column>
</rich:extendedDataTable>
 <a4j:commandButton id="btn_add_cars" action="#{assign_car.action_add_cars}" style="width: 70px; left: 15px; top: 282px; position: absolute" value="Add"/>

Backbean:

ArrayList<newlist> car_list = new ArrayList<newlist>(); //with it's getter and setter
public class newlist{
 String c_name;
public newlist(String name_of_car){
 this.c_name=name_of_car;
}
 public String getC_name() {
 return c_name;
 }
}

// function from which I add cars to list
car_list.add(new newlist(rs.getString("car_name")));


// value change event
public String value_change_car_selection_cb()
{
try
 {
 System.out.println("\n\t Test Selection made to : "+cb_select_car.getSubmittedValue());
 System.out.println("\n\t Row key on which the car is checked or unchecked : "+table_car_list.getActiveRowKey());
 }
 catch(Exception e)
 {
 System.out.println("Error in fetching selected cars...\n\t "+e);
 }
}

// action event of add button
public String action_add_cars()
 {
 try
 {
 // I don't have anything to write here
 }
 catch(Exception e)
 {
 System.out.println("Error in assigning cars...\n\t "+e);
 }
 return null;
 }

So, now if you can help me then its great for me.

Thanks for your support,
