To find the "column value" when clicked on Dynamic datatable

Question

I ahve done a dynamic table where the first row alone i ahve declared as command link.So when I click on the commadn link I need to get either column name or column count or rowdata.If I Get then I have some logic based on it to do.
I have placed my dynamic datatable code below.
public class Datatable2 extends PageCodeBase
UIData dataTable =new UIData();
public Datatable2()
UIColumn col;
UIOutput out = null;
ArrayList al=new ArrayList();
al.add("Item");
al.add("Creation date");
al.add("Priority");
Application app = FacesContext.getCurrentInstance().getApplication();
int colCount = 3;
for(int j = 0; j < colCount; ++j) {
out = new UIOutput();
col = new UIColumn();
if(dataTable.getRowIndex()==-1)
MethodBinding mb = app.createMethodBinding("#{pc_DataTable.item}", null);
HtmlCommandLink link = (HtmlCommandLink)app.createComponent(HtmlCommandLink.COMPONENT_TYPE);                     link.setActionListener(mb);
link.setAction(mb);
link.setId("Command"+j);
ValueBinding vb1 = app.createValueBinding("#{commands" + j + "}");
link.setValueBinding("value",vb1);
link.setRendererType("javax.faces.Link");
HtmlOutputText O = new HtmlOutputText();
O.setValue(al.get(j).toString());
link.getChildren().add(O);
col.setHeader(link);   
ValueBinding vb = app.createValueBinding("#{rows["+j+"]}");
out.setValueBinding("value", vb);
out.setRendererType("javax.faces.Text");
col.getChildren().add(out);
dataTable.getChildren().add(col);
public UIData getDataTable()
     return dataTable;
public void setDataTable(UIData dataTable)
this.dataTable=dataTable;
public Object[] getTableRows()
Object[] test = new Object[]{new String[]{"1","2","3"},
new String[]{"4","5","6"},
new String[]{"7","8","9"},
new String[]{"10","11","12"},
new String[]{"13","14","15"}};
return test;
this is my jsp code
<f:view>
<P>Place content here.</P>
<h:form>
<h:dataTable binding="#{pc_Datatable2.dataTable}" value="#{pc_Datatable2.tableRows}" var= "rows" />
</h:form>
</f:view>

Answer 1

hello,
u can use two types methods  u can create a dynamic action or by branching using conditional or java script code
for java script code just call the code when button clicked and in javascript function by using if condition u can redirect.
