Hi

I am using a rad combo box in our application, And we are using custom skin for combo box. there is a requirement to show scroll options. With custom skin horizontal scroll bar is working as expected, but along with horizontal scroll bar always vertical scroll bar is appearing even though it is not necessary. And the hover item style is not applying for entire item.

Please have a look at the combo box screen shots, mark up and the custom skin. And suggest me if you could find any mistake on that.

Thanks in advance,
Balaji Velasiri

Hello Balaji,

The vertical scroll appears because the height of the drop down is incorrectly calculated if there is a horizontal scroll. You can avoid this if you increase the height of the drop down a bit or handle the DropDownOpened event in this way:
function onDropDownOpened(sender) {
    var rcbScroll = sender.get_dropDownElement().firstChild;
     
    setTimeout(function() {
        var scrollHeight = rcbScroll.scrollHeight;
        var clientHeight = rcbScroll.clientHeight;
         
        if (scrollHeight > clientHeight)
            rcbScroll.style.height = scrollHeight + Telerik.Web.UI.RadComboBox._getScrollBarWidth() + "px";
    }, 500);
}

As for the second issue, you can use the following style to avoid it:
div.RadComboBoxDropDown .rcbList
{
    display: inline-block;
}
 
div.RadComboBoxDropDown .rcbItem,
div.RadComboBoxDropDown .rcbHovered
{
   display: inline-block;
   white-space: nowrap;
   width: 100%;
}

I hope this helps.
