Dictionary Mode

To enable spell checking in your web application you need to accomplish the following three tasks:

  1. Copy the needed dictionary files in your project's App_Data folder:
    The files are located in your <Telerik UI for ASP.NET AJAX installation folder>\App_Data\RadSpell. Create a RadSpell folder in your project's App_Data folder and copy the dictionaries there.
  2. Add the SpellCheck handler in your web.config file. This can be done by using one of the following approaches:
    1. Manually add the handler in your web.config file (in the httpHandlers section):
      <addverb="*"validate="false"path="Telerik.Web.UI.SpellCheckHandler.axd"type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI"/>
    2. Use the RadEditor's Smart Tag in Visual Studio. Note that the smart tag will appear only if you have the Telerik.Web.Design.dll file in your project's bin folder or in the GAC.
  3. Set the Language property of the RadEditor (by default it is set to "en-US"). If you want to change the language, you can do this by
    1. declaring the property in the RadEditor's declaration:
      <telerik:RadEditor runat="server" ID="RadEditor1">
      <telerik:SpellCheckerLanguage Code="fr-FR" Title="French"/>
    2. adding the language in the RadEditor's Languages collection. It is recommended to add the language in Page_Load:
      protected void Page_Load(object sender, EventArgs e)
      if (!Page.IsPostBack)
      new SpellCheckerLanguage("fr-FR", "French"));

      Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
      If Not Page.IsPostBack Then
      RadEditor1.Languages.Add(New SpellCheckerLanguage("fr-FR", "French"))
      End If
      End Sub
