You can add empty row in backend database!

Hi,

Can you please check from the database whether first row is empty or not? When the first record is empty, drop down list box gets the empty record. You can check it from database returning object size also.

Hi Ganesh Jonna/Krishnaveny,

Follow the steps

Create one Node using the following code. Inside the DoInit() method

Step 1:

IWDNodeInfo multiplenode = multipleinfo.addChild("MultiNode" , null, true, false, true, true, false, true, null, null, null);

multiplenode.addAttribute("roles", "ddic:com.sap.dictionary.string");

Step 2:

Assign values for Dropdown

IWDNode node1 = wdContext.nodeNodeA().getChildNode("MultiNode", IWDNode.NO_SELECTION);

IWDNodeElement elem1;

for(int s=0;s<5;s++){

elem1 = node1.createElement();

elem1.setAttributeValue("roles","Value"+s);

node1.addElement(elem1);

}

Step 3:

Inside Domodifyview create IWDDropDownByIndex UI Element and Bind it.

IWDDropDownByIndex dropDownList = (IWDDropDownByIndex)view.createElement(IWDDropDownByIndex.class, "drop");

IWDAttributeInfo info = wdContext.getNodeInfo().getChild("NodeA").getChild("MultiNode").getAttribute("roles");

dropDownList.bindTexts(info);

dropDownList.setWidth("100");

Finally add this Dropdown into container. Like this you can create more Dropdown and add action to the dropdown as dynamically.

<b>If you remove Blankspace at top position then

set Cadinality node to 1..1

Value answer=points</b>

Kind Regards,

S.Saravanan.

Why do you propose to do all this stuff by code instead of using the tools? IMHO this will irritate new Web Dynpro users.

Hi Sarvanan,

Its working fine for Context Value node. But In my case, It is model node and I am not able to change Selection propery for that context node. I also tried on manually created modelnode. But not able to change selection property.

Please provide solution for model node.

Thank you very much.

In My case, Mapping Type is Collection_and_Selection.

for other cases, your solution works.
