Hello Golu,

1. RadDock

You can hide the scroll bars of the RadDock by overriding the CSS class of its content. Here is the source code that does this (please note that if the !important flag is omitted the CSS class will not be applied). 

<style type="text/css">  
        overflow: hidden !important;  

In case you need to change the width and the height of the dock according to its content, our suggestion is to handle the OnClientInitialize client event, get the bounds of the RadDock's content and change accordingly the height and the width of the dock. Here is a sample event handler method (for the OnClientInitialize event) that does that:

function DockInitialize(dock, args) 
    var innerDiv = $get(dock.get_id() + '_C'); 
    var innerDivSize = $telerik.getBounds(innerDiv); 

2. RadChart

To change the colors of the series elements in RadChart you can define a custom color palette containing the desired colors. Here is how to do this:
    <telerik:RadChart ID="RadChart1" runat="server" SeriesPalette="customPalette"
            <telerik:Palette Name="customPalette"
                    <telerik:PaletteItem MainColor="Blue" SecondColor="Blue" /> 
                    <telerik:PaletteItem MainColor="Red" SecondColor="Red" /> 
                    <telerik:PaletteItem MainColor="Yellow" SecondColor="Yellow" /> 
                    <telerik:PaletteItem MainColor="Green" SecondColor="Green" /> 
Note that the SeriesPalette property of RadChart should be explicitly set to the name of the palette.
