Setting ComboBox scroll position

[Robert]

Hi,

I need the ComboBox to show the first item in the list when clicked, rather than automatically scrolling down to the first selected item.

How do I do this?

Thanks,

Rob

Hello Robert,

Try the following code snippet to achieve this.

Java Script:

<script type="text/javascript">
    var firstItem;
    function OnClientDropDownOpened(sender, args) {
        firstItem = sender.get_items().getItem(0);
        setTimeout("firstItem.scrollIntoView();", 500);
    }
</script>

Thanks,
Princy.

Hello Robert,

Please try handling the OnClientDropDownOpening of the RadComboBox in this way:

<script type="text/javascript">

    function onClientDropDownOpening(sender, eventArgs) {

        var highlightedItem = sender.get_highlightedItem();

        if (highlightedItem != null)
            highlightedItem.unHighlight();

       if(sender.get_items().getItem(0) != null)
            sender.get_items().getItem(0).highlight();

    }
</script>

Best wishes,

Thanks Princy, Kalina.

Princy's answer worked for me, although I didn't need to use setTimout(), I just called sender.get_items().getItem(0).scrollIntoView() from within OnClientDropDownOpened() and it worked fine.
