    Hi,

    The slider with previous releases has worked perfectly for me. However, since I updated to the latest Telerik release, as soon as I start to drag the slider, the browser pops up a "Microsoft JScript Runtime Error: Invalid arguments" error box. The problem only happens when I drag the marker. If I click on a different part of the slider, the marker moves to the clicked position fine.

    When I tried to debug the problem, the debugger shows the following code:

    ...onDragStart:function(v){var r=v.element;
    if(r===this._selectedRegionElement){return this._onDragStartRange(v);
    }var k=parseInt($telerik.getCurrentStyle(r,"left",0));
    if(isNaN(parseInt(r.style.left))){r.style.left=k+"px";
    }var f=parseInt($telerik.getCurrentStyle(r,"top",0));
    if(isNaN(parseInt(r.style.top))){r.style.top=f+"px";
    }...

    And the problem happens in the highlighted line. The value of "$telerik.getCurrentStyle(r,"left",0)" is "auto", and "r.style.left" is "". So you can see where the problem is. Any suggestions?

    Thanks

    Hi Ning,

    This is a known issue, which happens when the drag handle of a vertical RadSlider is dragged under IE7 (including Compatibility mode). It is brought to the attention of our developers and it will be fixed in a future release of the RadControls for ASP.NET AJAX, nevertheless I am not able to provide a firm estimate when a solution will be available. You can follow the status of this issue via its PITS Item.

    For the time being you can use the following workaround - just add the CSS code below in the head tag of your page:
    <style type="text/css">
        * + html div.RadSlider .rslVertical a.rslDraghandle
        {
            left: -9px !important;
        }
    </style>
