Change Image in Silverlight using Control Template

This article will demonstrate how to change image using ControlTemplate in Silverlight 4.

First of all make a new Silverlight project and put a name and save location. And add a new Silverlight User Control and add a few images in application and add this XAML code.

<UserControl.Resources>

<ControlTemplate x:Key="ButtonTemplate" TargetType="Button">
            <Grid>
                <VisualStateManager.VisualStateGroups>
                    <VisualStateGroup x:Name="CommonStates">
                        <VisualState x:Name="Disabled"/>
                        <VisualState x:Name="Normal"/>
                        <VisualState x:Name="MouseOver">
                            <Storyboard>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="mouseOverImage">
                                    <DiscreteObjectKeyFrame KeyTime="0">
                                        <DiscreteObjectKeyFrame.Value>
                                            <Visibility>Visible</Visibility>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="normalImage">
                                    <DiscreteObjectKeyFrame KeyTime="0">
                                        <DiscreteObjectKeyFrame.Value>
                                            <Visibility>Collapsed</Visibility>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                            </Storyboard>
                        </VisualState>

                       <VisualState x:Name="Pressed">
                            <Storyboard>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="mouseOverImage">
                                    <DiscreteObjectKeyFrame KeyTime="0">
                                        <DiscreteObjectKeyFrame.Value>
                                            <Visibility>Collapsed</Visibility>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="normalImage">
                                    <DiscreteObjectKeyFrame KeyTime="0">
                                        <DiscreteObjectKeyFrame.Value>
                                            <Visibility>Collapsed</Visibility>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="mousePressedImage">
                                    <DiscreteObjectKeyFrame KeyTime="0">
                                        <DiscreteObjectKeyFrame.Value>
                                            <Visibility>Visible</Visibility>
                                        </DiscreteObjectKeyFrame.Value>
                                    </DiscreteObjectKeyFrame>
                                </ObjectAnimationUsingKeyFrames>
                            </Storyboard>
                        </VisualState>
                    </VisualStateGroup>
                </VisualStateManager.VisualStateGroups>
                <Image x:Name="normalImage" Margin="0" Source="1.jpg" Stretch="Fill" />
                <Image x:Name="mouseOverImage" Margin="0" Source="2.jpg" Stretch="Fill" Visibility="Collapsed" />
                <Image x:Name="mousePressedImage" Margin="0" Source="3.jpg" Stretch="Fill" Visibility="Collapsed" />
            </Grid>

        </ControlTemplate>
    </UserControl.Resources>
Now add a button control inside of Grid.

<Grid x:Name="LayoutRoot" Background="White">

<Button Content="Hello Raj Kumar" HorizontalAlignment="Center" VerticalAlignment="Top"  Width="300" Height="300" Template="{StaticResource ButtonTemplate}" Margin="2,50,0,25" />

</Grid>
Now run the application to see the result.



Image1.

By default this image will load.



Image2.

This image will load when mouse over on the button.



Image3.

This image will load after mouse click.
