you can use node->get_lead_selection( ) which returns you element and using get_static_attributes( ) method you can get the values of that element.

If you want ot get the value when you press some link, have an action handler for that link and in the action handler method you can get the current element using wdevent's get_context_element method ( wdevent->GET_CONTEXT_ELEMENT( 'CONTEXT_ELEMENT' ) which returns element. From element you can get values using get_static_attributes or get_attribute methods.).

hai nikhil,

In the onloadchildren action of master column i call a method.

when the user clicks on the parent element of tree i need to get the selected element as that shud be given as input and the subelements shud be obtained.In lead select of table i have already obtained the values .all i need is to get the selected value when user clicks on the arrow next to the parent element in tree.

plz nikhil provide me some solution na.

Thanks n regards

hai armin,

There is no such method available under IWDNode.

Please check and let me know the correct code for that.

Hi,

Use

 try {
		IWDNodeElement nodeElement = wdContext.nodeOrders().getTreeSelection();
		// Change the line to your own attribute and data type (instead of object)
		Object value = nodeElement.getAttributeValue("<Your Attribute Name>");
		wdComponentAPI.getMessageManager().reportSuccess(value.toString());
	} catch (WDContextException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

First, don't add this code inside wdDoModifyView() but to the select action handler.

Second, change it into

try
{
  ICatalogEntriesElement selection = (ICatalogEntriesElement) wdContext.nodeCatalogEntries().getTreeSelection();
  String title = selection.getTitle();
  wdComponentAPI.getMessageManager().reportSuccess("Selected entry: " + title);
}
catch(Exception e)
{
  // should not happen
}

Just add the code in any event handler or controller method where you want to get the selected node, but not into wdDoModifyView().
