    RadSpell v3.x.x

    .NET version

    .NET 1.x, .NET 2.x

    Visual Studio version

    RadSpell offers an ButtonType property which specifies the type of the button that will start the spellcheck. Setting the ButtonType property of RadSpell 3.x to ImageButton will render the spellchecker button as an Image button with hover effect as well as a localization string over it:

    <asp:textbox runat="server" id="TextBox1">thiz iz miztacken</asp:textbox> 
    <rads:radspell runat="server" skin="Default" buttontype="ImageButton" id="RadSpell1" controltocheck="TextBox1"  />

    In some scenarios, however, it is required to render the "SpellCheck" button as an image without the hover effect as well as hide the localization string. Here is the steps providing guidance how to replace the ImageButton with your own image, remove the hover effect and hide the Spell Check string:
    1. You should open the ~/RadControls/Spell/Skins/<used_skin>/RadSpell.css file and modify the following classes. Change the background property with the url of the chosen image in the .RadSpell_Default_Ext.spLinkImg class:

      /*image link*/
          /* Change this url in order to modify the image when ButtonType='ImageButton'. The button will still be rendered as anchor! */
          background:url(Img/SpellCheck.gif) 0 0 no-repeat;

      and change the width and height dimensions in the following class to be identical to these of the Img/SpellCheck.jpg, or the image of your choice

          /* Change these dimensions to be the same as Img/SpellCheck.jpg, or the image of your choice. */

      Delete the following class to remove the image hover effect:

          background-position:0 -22px;/*the same as background images' height*/

      Note that you will need to explicitly set the skin of the control if you are using the Default skin and also that the Skin property is case sensitive!

      The provided example is made with the Default skin of RadSpell.
    2. To hide the button "Spell Check" localization string set the following code in the codebehind:
    C# code:

    protected void Page_Load(object sender, EventArgs e)
        RadSpell1.Localization["SpellCheckButton"] = string.Empty;

    VB.NET code:
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        RadSpell1.Localization("SpellCheckButton") = String.Empty
    End Sub

    Hi aadil,

    The code library above is for RadSpell for ASP.NET, while I assume you are using RadSpell for ASP.NET AJAX.
    In RadSpell for ASP.NET AJAX, the ImageButton value of the ButtonType  property renders a link with assigned .spLinkImg class that can be used to modify the look of the rendered control. You can see it in action in this demo.

    Best wishes,

    Hi Geller

    The CSS can just be in your own style sheet, this is what I have, I'm using 2009.1.527.35 but I would think the newer release is much the same.
