Armin,

Your code actually suits my situation and I am adding a row on click of the button

(Row contains Inputfields and labels)

When i have to create value attribute I need to give data type in addAttribute() function .

In layout for the first row I have choosen string as the data type.

While going with coding when i give the data type String or char or long.

It gives an exception.

You need a flag to signal that the elements should be added with the next call to wdDoModifyView().

Add a boolean context attribute "AddFields" to the view context and set it to true in the action handler for the button:

void onActionAddFields(...)
{
  wdContext.currentContextElement().setAddFields(true);
}

In method wdDoModifyView(), check the flag and reset it after the code that adds the fields:

(I assume the group has a MatrixLayout)

static void wdDoModifyView(...)
{
  if (wdContext.currentContextElement().getAddFields())
  {
    /* access group by ID given at designtime */
    IWDGroup group = (IWDGroup) view.getElement("groupID");
    IWDLabel label = (IWDLabel) view.createElement(IWDLabel.class, null);
    /* if new row in MatrixLayout should be started: */
    IWDMatrixHeadData labelLayoutData = label.createLayoutData(IWDMatrixHeadData.class);
    /* change settings for layout data if needed */

    label.setText("whatever");

    IWDInputField field = (IWDInputField) view.createElement(IWDInputField.class, null);
    /* if in same row as label: */
    IWDMatrixData fieldLayoutData = field.createLayoutData(IWDMatrixData.class);
    /* change field layout data if needed */

    field.bindValue("context.attribute.path");
    label.setLabelFor(field);
    group.addChild(label);
    group.addChild(field);
    wdContext.currentContextElement().setAddFields(false);
  }
}

Hi,

In your WdModifyView add this code simply.

// Root element of the every view capture the initially.

IWDTransparentContainer container = (IWDTransparentContainer)view.getElement(IWDTransparentContainer.class,"RootUielementcontainer");

// create the Group dynamically.

IWDGroup theGroup = (IWDGroup)view.getElement("InputGroup");

// create your ui elements add to be group.

IWDButton but = (IWDButton)view.createElement(IWDButton.class,"but");

but.setText("rama");

but.setTooltip("Developpment");

// create on more lablel

IWDLabel label = (IWDLabel)view.createElement(IWDLabel.class,"nagu");

label.setText("rama");

// finally add your label and button to Group.

grp.addChild(but);

grp.addChild(label);

// group to be added to container.

container.addChild(grp);

This might helps you.

Thanks,

Lohi.

Hi,

1. You always know the id of the Group UI element from the designtime. So in the wdDoModifyview() method, you will need to do

view.getElement("id_of_group");

2. For this go through <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/4f/07cf3dd28b5610e10000000a114084/frameset.htm">this</a> link.

Hi Sumit

in wdModifyView() write the code accordingly

IWDButton theButton = (IWDButton)view.createElement(

IWDButton.class, "butn");

IWDGroup theGroup = (IWDGroup)view.getElement("Group1");

theGroup.addChild( theButton);

this code adds button to your group with id "Group1".
