hi,

check out the link it explains u about all dropdownbyindex ui element

View – Programming UI and Navigation

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/9214b1e5-0601-0010-fdb0-ec3...

map the dropdownbyindex to value attribute which is inside a value node.

this code is for giving value to dropdown

public void wdDoInit()

{

//@@begin wdDoInit()

String[] letters = new String []

{"A", "B", "C", "D"};

//Create context elements for the node "X"

List nodeElements = new ArrayList();

for (int i = 0; i <letters.length; ++i)

{

IPrivateTestView.IXElement xElement =

wdContext.createXElement();

xElement.setY(letters<i>);

nodeElements.add(xElement);

}

//Bind node element list to the node

wdContext.nodeX().bind(nodeElements);

//Set node’s lead selection which determines the selected item

wdContext.nodeX().setLeadSelection(1);

//@@end

}

This is for seeing the value in dropdown once u enter inside the IE.If u want this is to be triggered only on clicking of the button

then give this code inside ur onsubmit() action of the buton.

hope this helps u,

Hi Praveen,

Go to layout of the view Create dropdownbyindexUI element

Create a node_userid having the attribute user_id and bind that attribute to texts property of the dropdown

write this code in doinit to populate values to the node

If all user ids are in an vector userid_vec

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

{

IPrivateApplicationView.Inode_useridElement element = wdContext.createnode_useridElement();

element.setAtt1(userid_vec.ElementAt(i));

wdContext.nodenode_userid().addElement(element);

}

bind an action to property onSelect. you can access the index of the selected element in the event handler in implementation

wdContext.nodenode_userid().getLeadSelection();

Link the onAction property of button to an action

Create an element of the node to which you should add these values

IPrivate<view name>.I<node name>Element element = wdContext.create<node name>Element();

element.set<attribute name>(wdContext.nodenode_userid().getElementAt(wdContext.nodenode_userid().getElementAt(wdContext.nodenode_userid().getLeadSelection()).getAttributeValue(" user_id").toString());));

wdContext.node<node name>().addElement(element);

Like this for deleting you can loopthrough the node from which you have to delete and identify the element

int index = 0;

for(int i = 0;i<wdContext.node<node name>().size;i++)

{

wdContext.node<node name>().get<node name>Elementat(i).getAttributevalue("user_id").equals(<Selected element>)

index = i;

}

Once you get the element you can remove it from table

wdContext.node<node name>().removeElement(wdContext.node<node name>().get<node name>ElementAt(index)

For update you once you get the index you can go to the element and modify it

What do you mean by retreiving the element?

Hope this helps you

Hi,

This will display the value in the dropdown by index.

String[] name=new String []{"name1","name2","name3"}

for(i=0;i<3;i++)

{

IPrivateMainview.INode_userElement x1=wdContext.nodeNode_user().createNode_userElement();

wdContext.nodeNode_user().addElement(x1);

wdContext.currentNode_userElement().setuser(name<i>);

wdContext.nodeNode_user().moveNext();

}

in the onselect method of the dd by index,

get the selected value.

String name=wdContext.currentNode_userElement().getuser();

Then set to the table attribute...
