Dynamicaly adding values to DropDownByKey

Hi,

You can populate dropdown values from webservice using the following steps. I assume you have idea about custom controller and better you have to use DropdownbyIndex intead of DropdowmByKey.

step1:

Create custom controller.Inside custom controller Bind input value then execute webservice.

step2:

Now you have value node which is returned from web service. After execute web service you can find size using the following code. create value(Role_Output) node and modelnode(Role_result) object using the code.

Step3:

<custom controller name>.IRole_ResultNode modelnode=wdContext.nodeRole_Result();

<custom controller name>.IRole_OutputNode valuenode=wdContext.nodeRole_Output();

valuenode.invalidate();

int size=modelnode.size();

Step4:

After find size using loop fetch values from model node into value node.Asume in this value node contains key and value.

for(int j=0;j<modelnode.size();j++){

<custom controller name>.IRole_ResultElement modelElement=modelnode.getRole_ResultElementAt(j);

<custom controller name>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setId(modelElement.getKey());

valueElement.setText(modelElement.getValue());

valuenode.addElement(valueElement);

}

step5:

After that bind this value node(Role_Output) into Component controller. Then Bind value node(Role_Output) from component controller into view.

Step6:

Finally bind dropdown UI Element into Role_Output node's attribute(ID).

Kind Regards,

Hi,

You can create a key on your own. You don't strictly need it from the webservice.

Quoting previously submitted code:

valueElement.setId("Key_" + loopIndex);//or whatever you might want to put.
