Lead Selection

[Former Member]

hi

I have created a dropdown menu(by Key).I have populated the values by binding the "texts" property to an attribute "num" that i have defined to be of simple type string.

How can I set the lead selection for this dropdown.

Plz Help

Hi,

I think u mean to say that have u binded selected key property to "num".

For lead select u can set this attribute with any of the value which you have defined in simple type.

for eg.

I have three values in simple type and suppose "dynpro" is one of the value which i want to be selected by default .

so before ur view is being u can set the "num" attribute with dynpro.

i.e

wdcontext.currentcontextelement.setnum("dynpro");

Hi,

If u have binded with the value attribute "att", and the drop down values are say a->AA,b>BB,c>CC,d-->DD....then write this code in wdDoInit()

wdcontext.currentcontextelement.setatt("a");

it will set the value as AA in the dropdown.

hi......

well dynamically you can do it

public void wdDoInit()
  {
    //@@begin wdDoInit()
	IPrivateViewDropkey1.IDropKeyElement ele = wdContext.createDropKeyElement();

	  ISimpleTypeModifiable myType=wdThis.wdGetAPI().getContext().getModifiableTypeOf("DropKey.Key");

	  IModifiableSimpleValueSet val = myType.getSVServices().getModifiableSimpleValueSet();
	  
	  val.put("1" ,"product1");
	  val.put("2" ,"product2");


    //@@end
  }

Now in the wdModifyView

 public static void wdDoModifyView(IPrivateViewDropkey1 wdThis, IPrivateViewDropkey1.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
  {
    //@@begin wdDoModifyView
	if(firstTime)
		{
    
//		  creating tranparent container
		IWDTransparentContainer tc = (IWDTransparentContainer)view.createElement(IWDTransparentContainer.class,"TransparentContainer");
	
//			creating dropdownkey 
				IWDDropDownByKey key = (IWDDropDownByKey)view.createElement(IWDDropDownByKey.class,"Dropkey");
					key.bindSelectedKey("DropKey.Key");
					key.setWidth("60");
					key.setVisible(WDVisibility.VISIBLE);
//setting the selection to the first value
					key.setSelectedKey("1");
				tc.addChild(key);
			
				IWDTransparentContainer root = (IWDTransparentContainer)view.getElement("RootUIElementContainer");
				root.addChild(tc);
    

//create an action called Click in the view
			IWDAction action = wdThis.wdCreateAction(IPrivateViewDropkey1.WDActionEventHandler.CLICK, "");
    
    
		
		key.setOnSelect(action);
	
		
	 
	
		}
    
	
    //@@end
  }

thanks Ayyapparaj

But please tell me how to populate a dropdown by index at design time(and not at run time).

I created a value node called "val" and created an attribute called num inside this value node. I bound this "num" to a simple type (of type string), In the enumeration of this simple type I have given the values I want to populate the dropdown with but the dropdown showed no values.

Plz help

You mix things up. DropDownByKey and DropDownByIndex have completely different data binding models.

You can create value sets at design-time using the dictionary type editor. These value sets then can be used by a DropDownByKey at runtime to provide its items.

For a DropDownByIndex you need a context node filled with elements which can only be done at runtime.

Hi,

Lead selection works only with Drop down by index as its bound to a node .

Hi himanshu,

You can use the following methods to set the selection.

wdContext.node.setLeadSelection(-1).

Here (-1) indicates selection nothing.

rewards points if helpful

best regards
