Description
Creating custom CSS styles for the RadButton to match the Bootstrap theme colors can enhance the visual consistency of your web application. This KB article also answers the following questions:
- How can I apply Bootstrap colors to Telerik RadButton?
- What is the correct way to style RadButton to match a Bootstrap theme?
- How do I ensure custom styles for RadButton override default styles?
Solution
To customize the RadButton styles and match them with Bootstrap themes, follow these steps:
-
Increase the specificity of your CSS selectors to ensure they override the default RadButton styles. This approach helps in applying the custom styles without using the
!important
declaration. -
Apply the CSS styles for each button state (default, hover, focus, etc.) as needed.
Here is an example of custom CSS that applies Bootstrap theme colors to RadButton:
/* Custom styles for Telerik RadButton */
html body .RadButton_Bootstrap.rbButton.rbPrimary {
background-color: #007bff; /* Bootstrap primary color */
border-color: #007bff;
color: #fff;
}
html body .RadButton_Bootstrap.rbButton.rbSecondary {
background-color: #6c757d; /* Bootstrap secondary color */
border-color: #6c757d;
color: #fff;
}
/* Repeat for other Bootstrap color classes as needed */
/* Styles for hover state */
html body .RadButton_Bootstrap.rbButton.rbPrimary:hover,
html body .RadButton_Bootstrap.rbButton.rbSecondary:hover {
opacity: 0.85;
}
- Add the custom class to your RadButton components in the ASPX page:
<telerik:RadButton ID="RadButton1" runat="server" Skin="Bootstrap" Text="Primary" CssClass="RadButton_Bootstrap rbPrimary" />
<telerik:RadButton ID="RadButton2" runat="server" Skin="Bootstrap" Text="Secondary" CssClass="RadButton_Bootstrap rbSecondary" />
<!-- Add more buttons as needed -->
By following these steps and increasing the specificity of your CSS selectors, you can successfully apply Bootstrap theme colors to Telerik RadButtons, ensuring a consistent and appealing design across your web application.
Here is the complete example
<style type="text/css">
/* Custom styles for Telerik RadButton */

color: #fff ;
padding-left: 0px;
}

- Consider using a CSS preprocessor like SASS or LESS for more dynamic and manageable styling.
