hi

Sample code for dynamic generation code

IWDInputField inputfield = (IWDInputField)view.

createElement(IWDInputField.class,"InputField1");

IWDAttributeInfo test =wdContext.getNodeInfo().

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

wdContext.currentContextElement().setAttributeValue("AttributeA", "Hello World!!!");// set the value of attribute

inputfield.bindValue(test);//bind the newly created attribute to inputfield

try like this and let me know

Hi,

you have to set value as

wdContext.currentContextElement().setAttributeValue("From", ""); you can set blank like this.

not like wdContext.currentContextElement().setFrom(" "); it wont be like this.

you are doing it in button Action? it is also dynamic? if yes, you have to create Action in design time that is manually you can not create it dynamically and do following code in runtime

// Creating a button
IWDButton objButton = (IWDButton)view.createElement(IWDButton.class, u201CbutSubmit");


// Setting tooltip and text to the button
objButton.setTooltip(op.getTooltip()); 
objButton.setText(op.getDisplayText());



// Create an action and assign the same to the button.
IWDAction theAction = wdThis.wdCreateAction(IPrivateDynamicView.WDActionEventHandler
					.GENERIC_ACTION,""); // here GENERIC_ACTION is the action created manually
objButton.setOnAction(theAction);

am I right?\

Hi,

Here is the right flow...

//Creating an attribute
wdContext.getNodeInfo().
	addAttribute("nameValue","ddic:com.sap.dictionary.string");




//Creating Input Field or any other UI element
IWDInputField ifName = 
	(IWDInputField)view.createElement(IWDInputField.class,"ifName");

//Binding the attribute with InputField
ifName.bindValue("nameValue");

Hi,

here i m giving code for your reference of a dynamic checkbox:

IWDCheckBox checkBox =

(IWDCheckBox) view.createElement(IWDCheckBox.class,

"checkBox" + count);

IWDMatrixHeadData checkHeadData =

(IWDMatrixHeadData) checkBox.createLayoutData(

IWDMatrixHeadData.class);

IWDAttributeInfo attrInfo;

info= wdContext.nodeCheckBox().getNodeInfo().addAttribute(

"Check" + count, "ddic:com.sap.dictionary.boolean");

checkHeadData.setVAlign(WDCellVAlign.TOP);

checkHeadData.setWidth("6%");

checkHeadData.setColSpan(1);

this line used to bind the context to the element:-

checkBox.bindChecked(info);

checkBox.setEnabled(true);

TitleRow.addChild(checkBox);

Hope this may help you.

Regards,

Deepak
