In this small Tips & Tricks, I will guide you through changing the Style of Caret of a Silverlight
TextBox control. It is very simple and you can easily do it using Visual Studio or Expression Blend. Here is a screenshot of the same:
In general, styling the caret is not required. But in some cases, you may need to change it to give your UI the look & feel of your entire application.
What is a Caret?
Caret is a small line always blinking inside your
TextBox control as shown in the above figure. The default color is always black. But you can change the color too as per your requirement.

To do the styling for all the
TextBox caret controls in your entire application, you need to add a
Style for your

xName to the style. If you set a name to the style, you have to explicitly set the style for each
textbox using the

style tag, add a setter property “
CaretBrush”. This allows you to change the caret brush color of your
textbox. Now set a value to it. You can use any color or color combination here. That means, you can set

GradientColorBrush to it. We will use three different colors (i.e.
Yellow & Blue) with equal Offset. Here is the XAML code:
<GradientStop Color="Red" Offset="0" />
<GradientStop Color="Yellow" Offset="0.5" />
<GradientStop Color="Blue" Offset="1" />
This will produce the following output:

Hope, this will help you in future when you need to set a different color to your
TextBox Caret. Feedback & suggestions are always appreciated.
