Removing elements from node

[Former Member]

Hello togehter,

I have implement the following code:

ResultSet resultSet;

resultSet = statement.executeQuery("select NAME from DNPERSO where COST like'" + InputFildKostStelle "%' or SNAME like'" InputFildName+"%'");

while (resultSet.next()){

ISelectionPersonsElement selection = wdContext.createSelectionPersonsElement();

selection.setPersons(resultSet.getString(1));

wdContext.nodeSelectionPersons().addElement(selection);

}

I use this for a search-funktion and it works fine.

My problem is now that I want to write an method to remove all the added elements of the "SelectionPersons Node".

Can anybody help me?

Hi Patrick,

Try this:

for(int counter=(wdContext.nodeSelectionPersons().size-1);counter>=0;counter--) {

wdContext.nodeSelectionPersons().removeElement(wdContext.nodeSelectionPersons().getElementAt(counter));

}

Thanks and regards

Hello Patrick,

You can remove the elements from the node in the following two ways.One way is to invalidate the node and the other way is to remove the elements using the

removeElement()

method of the node.

Examples:

First method:

wdContext.nodeSelectionPersons().invalidate

This will work well for your Value Nodes. However, for model nodes just bind suitable structure to the node and bind the instance of child node to the suitable parent nodes.

Second Method:

for ( int idx = ( wdContext.nodeSelectionPersons().size - 1 ); idx >= 0; idx-- )
	{
		wdContext.nodeSelectionPersons
().removeElement(wdContext.nodeSelectionPersons().getSelectionPersonsElementAt(idx));
	}

Hi,

If u want to remove all the element just write this code:

wdContext.node<name>().invalidate();

this will invalidate all the elements of the node.

If u want to remove a specific element from the node there is a method like remove():

wdContext.node<name>().removeElement();
