<form id="form1" runat="server">
<div>
<asp:DropDownList ID="DoprDownCalControl" runat="server" AutoPostBack="true">
<asp:ListItem Text="alex"></asp:ListItem>
<asp:ListItem Text="john"></asp:ListItem>
<asp:ListItem Text="manny"></asp:ListItem>
</asp:DropDownList>

<DayPilot:DayPilotCalendar ID="DayPilotCalendarControl" runat="server"></DayPilot:DayPilotCalendar>
</div>
</form>

CS Code :-- Nothing in CS page, Only page load event is defined.

After changing the index of dropdown i am getting this error.

Manjeet, I also have the same problem. Some of our users get this error and some don't get it. We tried to reproduce this ourselves but we were unable to reproduce this issue. We suspect that it has something to do with the regional settings of the machine or the language settings of the browser.
I tried your source code at my machine as-well but i was unable to reproduce this issue which you mentioned.
Can you mention which version of day pilot you are using and what are your regional and language settings for
your machine and the browser.
we are using Chrome(Version 39.0.2171.95 m, Language setting: English UK) Windows 7 and regional settings English UK.

This error may happen if the Chrome zoom is not set to 100%. Chrome has started to report the scroll position as a decimal number in one of its recent releases.

It's fixed now in the latest DayPilot Pro release:

I began to experience this error in Chrome (Version 40.0.2214.93 m) today right after having upgraded Java (now Version 8 Update 31)
