TextBox and Label Decoration
Child controls decoration
RadCaptcha offer two composite properties - TextBoxDecoration and TextBoxLabelDecoration that offer properties to apply style decoration (Figure 1) following the standard System.Web.UI.WebControls.WebControl decoration properties. You can set BackColor, Font, etc.
In the following example we will customize the border of the TextBox and the Font style of the TextBoxLabel.
<telerik:RadCaptcha ID="RadCaptcha1" runat="server">
<TextBoxDecoration BorderColor="Gray" BorderStyle="Solid" BorderWidth="2px" />
<TextBoxLabelDecoration ForeColor="Gray" Font-Italic="true" Font-Names="Verdana, Arial, Georgia" />
</telerik:RadCaptcha>
RadCaptcha1.TextBoxDecoration.BorderColor = Color.Gray;
RadCaptcha1.TextBoxDecoration.BorderStyle = BorderStyle.Solid;
RadCaptcha1.TextBoxDecoration.BorderWidth = Unit.Pixel(2);
RadCaptcha1.TextBoxLabelDecoration.Font.Names = new string[] { "Verdana", "Arial", "Georgia" };
RadCaptcha1.TextBoxLabelDecoration.Font.Italic = true;
RadCaptcha1.TextBoxLabelDecoration.ForeColor = Color.Gray;
RadCaptcha1.TextBoxDecoration.BorderColor = Color.Gray
RadCaptcha1.TextBoxDecoration.BorderStyle = BorderStyle.Solid
RadCaptcha1.TextBoxDecoration.BorderWidth = Unit.Pixel(2)
RadCaptcha1.TextBoxLabelDecoration.Font.Names = New String() {"Verdana", "Arial", "Georgia"}
RadCaptcha1.TextBoxLabelDecoration.Font.Italic = True
RadCaptcha1.TextBoxLabelDecoration.ForeColor = Color.Gray
