How do you set a default size of a control that you can resize?

How do you set a default size of a control that you can resize?

I have been looking at a code sample from Charles Petzold.

It is from here:

http://www.charlespetzold.com/blog/2009/05/Realizing-a-Fisheye-Effect-in-Silverlight.html
it uses mouse over methods to increase the size of button classes.

I have it working but I want to make some modifications. I want the starting size of the button to be larger. I do not know how much of the code I need to post here to make the issue clear enough. The XAML for the page describes a "FisheyeButton" that is described in a seperate xaml file. Something like this:

<StackPanel x:Name="LayoutRoot" Width="1017" Orientation="Horizontal" Height="253">   
    <src:FisheyeButton Style="{StaticResource btnStyle}" ButtonContent="Button No. 1" />   
</StackPanel>

The functionality of the project is such that if I give the Fisheyebutton a width and height a set size at this loction, the effect where the size of the control the effect of becoming larger does not happen. In other words, if I write in the <src:FisheyeButton... tag above Width="100", then the button does not behave at run time as it should.

In the same page.xaml file, the btnStyle is defined like this:

<UserControl.Resources >
   <Style x:Key="btnStyle" TargetType="src:FisheyeButton">
      <Setter Property="VerticalAlignment" Value ="Center" />
      <Setter Property="HorizontalAlignment" Value ="Center" />
      <Setter Property="FontSize" Value ="12" />
   </Style >
</UserControl.Resources >

I wonder if perhaps at this point, I can add a "Setter" property to define a default starting widh and height for the class.

The animation, what makes the custom button class grow larger and also return to a normal size, is done in a seperate XAML for the Fisheyebutton class:

<UserControl x:Class="FisheyeButtons6.FisheyeButton" 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

            <vsm:VisualStateGroup x:Name="CommonStates"> 
                <vsm:VisualState x:Name="Normal"> 
                    <Storyboard> 
                        <DoubleAnimation Storyboard.TargetName="presenter" 
                                         Storyboard.TargetProperty="ScaleX" 
                                         To="1" Duration="0:0:0.25" /> 
                        <DoubleAnimation Storyboard.TargetName="presenter" 
                                         Storyboard.TargetProperty="ScaleY" 
                                         To="1" Duration="0:0:0.25" /> 
                    </Storyboard> 
                </vsm:VisualState> 
                <vsm:VisualState x:Name="MouseOver"> 
                    <Storyboard> 
                        <DoubleAnimation Storyboard.TargetName="presenter" 
                                         Storyboard.TargetProperty="ScaleX" 
                                         To="3" Duration="0:0:1" /> 
                        <DoubleAnimation Storyboard.TargetName="presenter" 
                                         Storyboard.TargetProperty="ScaleY" 
                                         To="3" Duration="0:0:1" /> 
                    </Storyboard> 
                </vsm:VisualState> 
            </vsm:VisualStateGroup> 
        </vsm:VisualStateManager.VisualStateGroups> 
 
        <Button> 
            <src:ScalableContentPresenter x:Name="presenter" /> 
        </Button> 
    </Grid> 
</UserControl>

That question doesn't seem related to the ArcGIS API, may be best answered at a Silverlight forum http://forums.silverlight.net/.
