Hi ,

The UI element dropdownbykey , you might have binded the context attribute which was in turn mapped to the simple type. To select a default value you could set the attribute value as well to the one which you want as default.

In default case it picks the value which has key value 0 ( generated automatically at design time )

Hai,

wdContext.currentContextElement().setPurchase List("shirt");

Yea, as Armin said, the first thing one needs to do for any query is to check the Java Docs.

Why not just reading Javadoc?

Hi yzme,

There are 2 ways of doing that:

1.Attribute that you've binded to DDKey UI element.Stores the key of the rendered value at runtime.So set it to the default key (say Key 0 ) in your case.

2.In the wdModifyView you can get the DDByKey element and it has a method

as setSelectedkey("Default key");

Hi,

You can set the default value of the DDBK if you know the key value of the attribute that is displayed.

Assuming "PurchaseList" as the attribute that is mapped to selecteKey property of the drop down by key.

wdContext.currentNodeDDBK.setPurchaseList(<your key for shirt>);

Hi,

1)Create simple type and click Enumeration tab,then click New

2)Enter the Shirt as your first element,then it will set as default key 0

3)Create an attribute as SELECT and bind this attribute with simple type

4)Insert Dropdownbykey UI element,bind this with SELECT attribute

5)While runtime,shirt will set as first element....

Hi Yzme,

I understand that you created SimpleTypeDictonary for your DropDownValues and your context attribute is binded with above SimpleTypeDictonary. And your DD UI element is mapped with context attribute.

In the view of init or outboundplug method.

wdContext.currentContextElement()set<<b>ContextAttributeName</b>>("<b>SimpleTypeDictonary Value</b>");

B for blouser

Default Value

Exp :wdContext.currentContextElement()setPurhaseDD("B");

Hi,

use setLeadSelection() method on your node which you have bind to your DropDown. For Example

wdContext.nodeAirlineValue().setLeadSelection( int element no);

Thanks and Regards
