default value of DropDownByIndex

Posted on Oct 19, 2006 at 03:29 PM 20 Views

hello,

i am searching for the possibility to access the default value of a dropdown element in java WebDynpro. I exactly mean the "blank" value in the top of a drop down box.

In my scenario i want to display different data in a table related to the selected values in the drop down box. If the user choose the "blank" data should be diplayed as well.

does anyone have a idea??

thanks in advance,

regards,

rene

    This line set to the default FIRST LINE BLANK

    wdContext.nodeYOUR_NODE().setLeadSelection(-1);

    This control say you if BLANK line is selected

    if (wdContext.nodeYOUR_NODE().getLeadSelection(-1) == -1){

    //BLANK CASE

    }

    A DropDownByIndex displays an empty value if the node to which it is bound has no lead selection.

    Example:

    dropdown.texts -> SomeNode.SomeAttribute

if (wdContext.nodeSomeNode().getLeadSelection() == IWDNode.NO_SELECTION)
{
  /* drop-down displays empty value */
}
