    I have used the Telerik RadCaptcha control in a number of projects and can never get a skin to work with it. All other controls are using the skin defined in the Web.config file in the key:

    <add key="Telerik.Skin" value="Bootstrap"/>


    Does anyone have any idea why the RadCaptha is the only control that doesn't follow this in my projects?

    Hello David,

    The captcha is not really styled to begin with and so changing skins does little to affect it. The image is always the same regardless of the skin, the buttons are <asp:LinkButton> controls and the textbox is a plain <asp:TextBox> that has a label for the instructional message.

    The textbox and info message label can be decorated with a RadFormDecorator, like it is done in our demos: https://demos.telerik.com/aspnet-ajax/captcha/examples/overview/defaultcs.aspx.

    You can also set appearance properties to the captcha to match your site stylesheet: https://docs.telerik.com/devtools/aspnet-ajax/controls/captcha/appearance-and-styling/textbox-and-label-decoration.
