    I am getting a javascript error - 'Invalid Argument' when I try to select a color using RadColorPicker.
    I have added following code in my aspx


    <telerik:RadColorPicker ID="RadColorPicker1"















    OnClientColorChange="ChangeColor" runat="server" />

    I have follwoing script:



    script language="javascript" type="text/javascript">



    var ChangeColor = function(a,eventArgs) {




    this.ClientID %>.Color = (eventArgs.get_color) ? eventArgs.get_color() : a.get_selectedColor();


    </script >

    I am suspecting this to be some version (may be RAD version / XML version / IE version) issue. 

    On debugging I fpund that the issue is  in ScriptResource.axd  in the following function. error line marked in bold:



    var _15=(this._selectedColor==_13.value)?"selectedcolor":"colorbox";

    var li=document.createElement("li");

    var _17=document.createElement("a");




    _17.style.background=_13.value; // HERE IS WHERE MY DEBUGGER STOPS

    var _18=this._createSpanEl("",_13.value);





    return li;





    Please guide.

    Thanks and Regards,

    Hello Maitreyee,
    I tried to reproduce the problem you describe, but to no avail. Below is the code of my page:
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
    <html xmlns="http://www.w3.org/1999/xhtml"
    <head runat="server"
        <title>Untitled Page</title> 
        <form id="form1" runat="server"
            <asp:ScriptManager ID="ScritpManager1" runat="server"
            <telerik:RadColorPicker ID="RadColorPicker1" ShowIcon="true" Preset="Standard" ShowEmptyColor="false" 
                SelectedColor="#000000" OnClientColorChange="ChangeColor" runat="server" /> 
            <script language="javascript" type="text/javascript"
                var ChangeColor = function(a,eventArgs)  
                    <%= this.ClientID %>.Color = (eventArgs.get_color) ? eventArgs.get_color() : a.get_selectedColor(); 
            </script > 

    I tested in both IE and FF with the latest version of the suite, as you have specified - version 2008.3 1314.

    I actually did get an error - "__Page is not defined", but it was not connected to the code of the RadColorPicker, but rather to the following line:
    <%= this.ClientID %>.Color 

    In case you can send me a simple running project, demonstrating the problem, I will do my best to find what is causing it.
