set current node

[Former Member]

I got a table with nodes with the context:

Person

- ID

- Name

All the nodes is listed in a table in dynpro. My problem is that i want a certain node default selected in the table. All i know is the ID of the node. Got any suggestion of how to do this?

Hi Kristoffer,

What do you mean by <b>nodes</b>? Are you talking about value node which we create through context or is it something else. The code i have given is for a value node Person which will be mapped with the datasource property of the table and it contains two attributes ID and Name.

So please explain on your scenario.

Yes, Its a valuenode that is created in the context.

Lets say you have this context: Persons (node)

Name (value attribute), ID (value attribute)

This is binded to a table, that could look like this:

1 K.E

2 O.C

3 L.A

In dynpro tables you can set one row to be selected.

I get an ID as an input paramter i.e 2. Then i want the row with the ID 2 to get selected. If thats not possible, i want to set the the row with the ID 2 on top.

Hi Kristofer,

Let us say you have the value to be checked in a string 'str'.

IPrivate<View_name>.IPersonsElement elmt;

for(int i=0;i<wdContext.nodePersons().size();i++)

{

elmt = wdContext. nodePersons().getPersonsElementAt(i);

if(elmt.getID().equals(str);

{

wdContext. node<node_name>().setLeadSelection(i);

break;

}

}

Hope this helps you,

Best Regards,

Nibu.

Thanx... I tried it now, but it doesnt seem to work.

The node that is selected the first time, is selected every time i go to the table with the nodes.

I.E i select row 2 in the table, and go out.. go back to the table and the row 2 is selecten.. even that it the input paramter is something else..

But in this if statement:

if(elmt.getID().equals(str);

{

wdContext. node<node_name>().setLeadSelection(i);

break;

}

}

How can i set the node it finds to be the startnode?

hi Kristoffer,

U can use the following peice of code

 wdcontext.nodePersonNode().currentPersonNodeElement().setCurrentID("<Your Default ID>");

But that code changes the ID for the current person.

I dont know which node it is. All i have is a list of nodes, and a certain ID. The node that the certain ID belongs to, is the node i want to be selected.
