How to write lead selection method for a tree by nesting table column

Hi,

I have implemented a table with TreeByNestingTableColumn(To show the tree structure in the table).I am not able to get the selected row element in lead selection method.(I am able to get parent element.) .

could anyone please tell me about this code?

What do you mean with "I am able to get the parent element"?

I am getting parent element means I am able to get value for the node(Instance node in my code)but do not know how to get value for recursive node(examles in my code.)

Hi,

Follow the below steps to the solution for your problem

1. Create Action "LeadSelection" in View with parameter (name : 'seletedItem'

and type : I<your node>Element

2. Bind this action to Table property "onLeadSelec"

3. In wdModify()

IWDTable table = (IWDTable) view.getElement("Your table id");

table.mappingOfOnLeadSelect().addSourceMapping("nodeElement", "selectedEle");

4. In onActionLeadSelection()

wdComponentAPI.getMessageManager().reportSuccess("Selected Item : "+selectedEle.get<Your Node Attribute>());

Let me know if you need more clarification

Thanks

Hi Tatayya,

Thanks for the answer.I tried this but I forgot to add mapping.

Now it is working fine.

Hi,

have you tried the currentElement method on the node that is bound to the table.

Ex: wdContext.currentContextElement();

Hi ,

Yes I tried with current element also(WdContext.currentInstance element) but it is giving only the parent node.

My node name is instancenode and under this node I have recursive node examples.

hi,

 public void onActionleadselection(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
  {
int n = wdContext.nodeTable().size();
		int leadSelected = wdContext.nodeTable().getLeadSelection();
	
		// loop backwards to avoid index troubles
		for (int i = n - 1; i >= 0; --i) {
		  if (wdContext.nodeTable().isMultiSelected(i) || leadSelected == i) {
						  wdContext.nodeTable().getElementAt(i));
}
}

You mean posting this code fragment from the Table Tutorial with a comment that is misleading without the delete-operation inside the loop will help?
