Hello,

I tried in this way but my issue is not solved.

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.

but it is not enabled. In properties ennabled-true, readonly -false but it is not enabled.

it's better you ask in this way. then we can guide you better.

where you create your attribute?

if it is not created directly under root context, you have to set the node cardinality to 1:1, or using code to create an element of that type.

the point here is the context you defined is just to provide type information, you have to new a object of that type to get memory allocated, which will in turn enable the UI control.

Ok. Defnetly i will improve in asking question directly.

I created an attribute under root node which cardinality is 0..n and selection is 0..1.

[junwu · Accepted solution]

attribute has no cardinality, only node has.

you can create a attribute under the root context with the type you defined before and assign it to the UI control

yes sir,

What i specified before is for node only. i bound it ui element also but am not getting. The same way i tried for radio button i got it. But for Dropdown its troubling.

Hi Venkat,

The cardinality of the context node should be 1:1 (as John mentioned) and not 0:n. Now create a context attribute under this node which has the same type as the dictionary simple type created by you and then map this attribute to "selectedKey" property of DropDownByKey UI element.

Hi Jyothi,

You can try the following code to create a List using DropDownbyIndex..

IPrivate<view>.I<Contextnode>Element ele = null;
for(int i=0;i<<Contextnode>.size();i++)
{
ele = wdContext.create<Contextnode>Element();
ele.set<attribute>(<list value>);
wdContext.node<Contextnode>.addElement(ele);
}

Regards,

Vijay.
