hi,

i Hope u hace created the two Dropdown by Index , first for listing the Values as u have mentioned(1,2,3,4,.....) .

now based on the user input only we have populate the second DropDownByIndex.and u have might have binded a context attribute for the second dropdown.(and also to the first drop down)

if the User selects the first dropdown say "1". get the user selected value from the first dropdown .

String value=wdContext.currentContextElement.geturContextAttributeName();

use if conditional statement.

as if(value =="1"){

populate the second dropdownbyindex.

}

thanks and regards

hi,

For Drop Down By Index we cant use any dictionary , so we have populate the First Drop dwon in the doinit method of the View.

In the View Implementation editor :

In DoInit method :

for (int i=1;i<8;i++){

ITestElement element = wdContext.createTestElement();

element.setData(i);

wdContext.nodeTest().addElement(element);

}

here the test is the node Element and data is the Attribute.

Note : we have create a node element and the Attribute in the Context of the View Controller.

In the First drop down we have On Event Property called OnSelect.

create an Action for thr first DropDown .say the Action Name is PopulateSecondDropDown.

Note : go the Action Tab of the View and create the Action.

Now Switch to the Java Editor of the View .

in the OnActionPopulateSecondDropDown paste this code:

int i1 = wdContext.currentTestElement().getTest();

wdContext.nodeTest1().invalidate();

for(int i=1;i<8;i++){

ITest1Element element = wdContext.createTest1Element();

element.setTest1(i"/"i1);

wdContext.nodeTest1().addElement(element);

}

Hope Ur problem get Resolved

Thanks and regards
