You could read more about WebSchedulerRecurrenceMode and WebSchedulerRecurrenceRangeMode in the WebScheduler documentation under the article titled "WebSchedulerRecurrenceMode Enumeration" and "WebSchedulerRecurrenceRangeMode Enumeration". You could also try adding recurring event in our sample and check the new entry in the database in order to determine the value.

Programmatically changing the data source connection will also work with such connection, as long as the database has the same table structure and query defined in the database operation of the WebScheduler.

It seems Firefox did not recognoze the Add function in the Options object. In order for compliance with Firefox we will have to add the new options using indexer. Here is the new snippet:

function display(idx) {

    var grid = ISGetObject("WGActivity");
    var tblElm = grid.RootTable.GetElement(WG40.BODY, WG40.HTMLTABLE);
    
    var selRow = tblElm.rows[idx];    
    var optText = "";
    var optVal = "";
    
    for (j = 0; j < selRow.cells.length; j++) {
        var val = selRow.cells[j].innerText;
        if(j == 0)
            optVal = optText = val;

        if (selRow.cells[j].getElementsByTagName("input").length > 0)
            if (!(val == " " || val == "<nobr> </nobr>") && 
                j > 0 && selRow.cells[j].getElementsByTagName("input")[0].checked)
                    optText += " " + val;   
    }

    var listBox = document.getElementById("lbactivity");
    var doAdd = true;
    
    for (var i = 0; i < listBox.options.length; i++)
    {
        if (listBox.options[i].value == optVal) {
            doAdd = false;
            listBox.options[i].text = optText;
            if (optText == optVal)
                listBox.options[i] = null; 
            break;
        }
    }

    if (doAdd)
        listBox.options[listBox.options.length] = (new Option(optText, optVal));
}
