Hi

--> Take DropDownByIndex UI Element in the Layout Tab.

--> Take One ValueNode Named "Vn_test" in the Context.

--> Take One Value Attribute Named "Va_test" for the Node

"Vn_test".

Set : Cardinality --> 0..n

Selection --> 1..1

Singleton --> True

--> Bind "Vn_test" to the texts Property of the DropDownByIndex.

--> Set the "Vn_test" Node Properties in the Context Tab as

--> Write the Code in wdDoIniit method of implementation tab of that view in which u have taken dropdown.

IPrivate< Your View Name>.IVn_testElement test;

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

{

test = wdContext.createVn_testElement();

test.setId(" "+i); // this will show 0,1,2 in dropdpwn.

wdContext.nodeVn_test().addElement(test);

}

This will definately work

Thanks

Hi Sonal,

1.) Take DropDownByIndex UI Element in the Layout Tab.

2.) Take One ValueNode Named "Employee" in the Context.

3.) Take One Value Attribute Named "Id" for the Node "Employee".

4.) Bind "Employee.Id" to the texts Property of the DropDownByIndex.

5.) Set the "Employee" Node Properties in the Context Tab as

a.) Cardinality --> 0..n

b.) Selection --> 1..1

c.) Singleton --> True

6.) Write the Below Code in the Implementation Tab.

IPrivate<View Name>.IEmployeeElement empEle;

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

{

empEle = wdContext.createEmployeeElement();

empEle.setId("Emp Id "+i);

wdContext.nodeEmployee().addElement(empEle);

}

It will Create DropDownList.

HI

Refer this code

IWDNodeInfo SeqNodeInfo = wdContext.nodePeriod().getNodeInfo();
IWDAttributeInfo Seqinfo = SeqNodeInfo.getAttribute("AttributeName");
ISimpleTypeModifiable Seqstm = Seqinfo.getModifiableSimpleType();
IModifiableSimpleValueSet Seqsvs = Seqstm.getSVServices().getModifiableSimpleValueSet();

for(int i=0; i<5; ++i)
{
Seqsvs.put(iyear.toString(), iyear.toString());
iyear = iyear - 1;
}

Hi,

suppose your attribute is called "MyAtt" and the node is called "MyNode".

 IModifiableSimpleValueSet valueSet = wdContext.nodeMyNode().getNodeInfo().getAttribute(IPublic<controllerName>.IMyNodeElement.MY_ATT).getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();

valueSet.clear();

for (int i = 0; i < dataArray.size(); i++) }
  valueSet.put(dataArray->key, dataArray->Text);
}

Bind "MyAtt" to selected property of dropdownlistbox.

Hi Sonal,

You can create Dropdown in two ways,

1. Create a simpleType.(DictionariesLocal dictonarysimpleTypes)

2. Go to enumeration , and add the data.

3. Create a context and in the property of the context , choose select and select the local dictionary and select the one which you have created.

4. You can create a DropDownKey and map to the context.

Dropdown by Index.

If Vn_Dropdown is your node and Va_data is the attribute. and testview is the view name you can do this way

IPrivateItestView.IVN_DROPDOWNelement element=null;

element=wdcontext.nodevn_dropdown.createvndropdownelement();

element.setva_data();

wdcontext.nodeVn_dropdown().add(element);

this would add the data you can repeat the create steps again and again.Sorry for the Typos as i am trying to write directly.
