Creating a Custom Skin

Creating RadSocialShare Custom Skin

Each of the controls included in the Telerik® UI for ASP.NET AJAX suite is styled by two CSS files that are loaded in a certain order. The first one - ControlName.css, also called the base stylesheet contains CSS properties and values that are common for all skins, i.e. it is layout-specific, not skin-specific. These are CSS float, padding, margin, font-size, font-family, etc. In the general case, when creating a custom skin for a control this file should not be edited, unless the custom skin needs different sizes, paddings or margins. The second file represents the actual skin of the control, and its name consists of the control name plus the skin name, i.e. SocialShare.Default.css. Upon creating a custom skin for the control, one should edit that particular file, as it contains skin-specific CSS properties, and references to images, colors, borders and backgrounds.

Creating a Custom Skin for RadSocialShare for ASP.NET AJAX from an Existing One

  1. In your project, create a new directory named Skins

  2. In the Skins folder create a new directory MyCustomSkin

  3. Go to ~/[TelerikControlsInstallationFolder]/Skins/Default and copy SocialShare.Default.css and the Skins/Default/SocialShare folder in your Skins folder.

  4. Rename SocialShare.Default.css to SocialShare.MyCustomSkin.css and the folder Default to MyCustomSkin

  5. When you are finished you should have Skins/MyCustomSkin/SocialShare.MyCustomSkin.css and Skins/MyCustomSkin/SocialShare. The last folder contains the images for MyCustomSkin

  6. In order to support multiple skins of RadSocialShare on a single page, the wrapping skin-specific class is coined by the name of the control, RadSocialShare plus underscore ("_") plus SkinName, i.e., .RadSocialShare_Default, so in order to create a custom skin out of the Default skin, we should rename all occurrences of "Default" in SocialShare.MyCustomSkin.css to "MyCustomSkin" as shown below:


  7. Add a new server declaration of RadSocialShare on your page, and set Skin="MyCustomSkin" and EnableEmbeddedSkins="false":


    <telerik:RadSocialShare RenderMode="Lightweight" ID="ssh1" runat="server" EnableEmbeddedSkins="false" Skin="MyCustomSkin">
  8. Register SocialShare.MyCustomSkin.css in the <head>…</head> section of your webpage.In order to have the CSS applied correctly, the base stylesheet should come first in the DOM:


    <link href="Skins/MyCustomSkin/SocialShare.MyCustomSkin.css" rel="stylesheet" type="text/css" />

    Make sure the path to the files is correct; otherwise the skin will not apply.

  9. Reload the page, and if the steps 0-8 have been followed correctly, you will see RadSocialShare running a custom Default skin set as an external resource

Modifying the Image Sprites to Achieve Totally New Looks for the Skin

Each skin of RadSocialShare consists of one image sprite common for all embedded skins which is placed in Skins/Common/SocialShare/SocialShareSprite.png . In order to override it for the custom skin, you will need to do the following steps:

  1. Copy the sprite from Skins/Common/SocialShare/ and paste it to Skins/MyCustomSkin/SocialShare folder.

  2. As in the embedded skin the background image URL is set in the base stylesheet, you have to override it in SocialShare.MyCustomSkin.css:


    .RadSocialShare_MyCustomSkin .sshIcon

Explained below is a simple method for modifying the image sprites of RadSocialShare with Adobe© PhotoShop to achieve new looks without creating a new design:

  1. Drag SocialShareSprite.png in Adobe© PhotoShop

  2. From the menu bar select Image » Mode » RGB Color to prepare the images for editing (convert from optimized Indexed Color to RGB Color):


  3. Press Set Foreground Color in PhotoShop's toolbox to invoke the color picker dialog:


  4. Select a color that you like from the color dialog and then close it:


  5. Choose the image you will modify, and select Image » Adjustments Hue » / Saturation to open the Hue / Saturation dialog of Adobe© PhotoShop:


  6. Check the colorize checkbox in the Hue / Saturation dialog, and the image you have selected will be immediately colorized in the hue you have selected from the toolbox:


    You may then play with the Hue, Saturation and Lightness sliders to fine tune or further modify the image

  7. Press "OK" when you are finished

  8. Select Image » Mode » Indexed Color to flatten the layers of the image

  9. Save and close the image

  10. Repeat Steps 5 - 9 for each of the remaining images

  11. Once you are ready, save your work and reload the page. You will have a brand-new skin based on Telerik's Default skin of RadSocialShare

  12. This is not mandatory, but you could decide to change RadSocialShare background and border colors to match the newly colorized sprite
