Just the idea -- You can implement your idea by putting the ScaleTransform object with specific name into your expected object/control. With the name, you can use FrameworkElement.FindName method to get the ScaleTransform object, and then you change the properties in runtime.

This works for me ..........one more thing incase if slider is in childwindow and MainPage is made of mutiple usercontrols/ bands. Then i want to have the same functionality using event/delegate concept so that any control in mainpage can move according to slilder movement. Please guide me through if you have any idea.

Here's an even simpler version, it simply scales a Canvas using a slider control.
You need two Canvas controls, one for the outer Canvas, to keep the controls all in the right size, then an inner Canvas, which you can add all your scalable content to...

The XAML

<UserControl x:Class="SilverlightZoom.Page"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Width="400" Height="300">

<Canvas.RenderTransform>

</Canvas.RenderTransform>

</Canvas>

</StackPanel>

</Grid></UserControl>

Then the Slider1_ValueChanged method...

private void Slider1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)

{

TextBlock1.Text = Slider1.Value.ToString();

CanvasScaleTransform.ScaleX = Slider1.Value;

CanvasScaleTransform.ScaleY = Slider1.Value;

}

Perhaps you should start at the MSDN Libary and by downloading Microsoft Blend to begin your Silverlight development. Instead of posting and asking someone to create a project for you. Here is a link for MSDN Libary for Silverlight 1.0: http://msdn2.microsoft.com/en-us/library/bb404710.aspx

I don't have specific code, but generally you just want to use a ScaleTransform (in the RenderTransform) and tie that to whatever control mechiism you're using.
