Is it possible to have the default selection on a dynamic multi-select listbox be generated by WebFOCUS after the listbox values have been populated?

Shane

Shane,

Think about where the select box is - it is in your HTML file and not WebFOCUS. This should enable you to answer your own question

WebFOCUS might be being used to populate the listbox but the data is passed to the client browser where JavaScript takes over.

Tony,

Thanks for the reply. However when we try to use JavaScript, we found out that it executes before the WebFOCUS code does. Hence, we get javascript errors because there's no value in the listbox at runtime.

Shane,

This is correct. If you use the HTML painter and therefore the IBI Javascript modules, then when your HTML page loads it runs a series of functions that populate the various controls on your page. It does this by retrieving an XML data file from WebFOCUS. This XML file is then parsed into pairs of data values that are used to poplate the list box, one for Value and one for Display.

Once these processes have been run then you should be able to run your own function to make the selections that you require.

In your HTML code you should have a section that looks like this -

<SCRIPT id=clientEventHandlersJS type=text/javascript>
//Begin function window_onload
function window_onload() {
UpdateData();
// TODO: Add your event handler code here
}
//End function window_onload
</SCRIPT>

All you have to do is add your function calls after the TODO comment.

I have not tried this but it is something I heard. If you call the html page and pass the name=value parameters on the URL it set the default values. Have not tried but and do not hold me to it. Please let us know what happend when you try it.
