Creating a TextBlock
First of all, create a TextBlock in the XAML page and give it a name so that we can access it in the code behind file at run-time.
I have created a TextBlock named "lblStatus" and assigned some property. The Foreground color is set to "Green"
Also add a Button.So, that when you click the button we will change the Foreground color of the Text in the TextBlock
I have created a Button name "btnChangeColor" and assigned some properties and and "Click" event handler "btnChangeColor_Click"
1.) TextBlock x:Name="lblStatus" Width="100" Height="30" Text="Hi This is Demo"
2.) Button x:Name="btnChangeColor" Content="Change Color" Click="btnChangeColor_Click"
Changing the Foreground in Code Behind
Now go to the event handler "btnChangeColor_Click" and add the following line (if you want to change the color to basic colors).
myTextBlock.Foreground = new SolidColorBrush(Colors.Red);
if you want to change the color and you know the "RGB" values then use this line
myTextBlock.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 0, 0));
Note: I have removed the "<" and "/>" sign before and after the "TextBlock" and "Button". If I keep then then the browser(Silverlight plug-in) interprets the XAML code and shows a "TextBlock" and "Button" instead of the code.
Thank you. I was looking exactly for this information.
