  • In this example you can review how to use the editor's ToolProviderID property. The ToolProviderID property helps to significantly reduce the HTML markup and JSON(Javascript Object Notation) sent from server to the client when multiple RadEditor objects with the same tools are used on the same page. The ToolProviderID should be set to the ID of another RadEditor e.g.

    ASPX:

    <telerik:radeditor runat="server" ID="RadEditor1"></telerik:radeditor>
    <telerik:radeditor runat="server" ID="RadEditor2" ToolProviderID="RadEditor1"></telerik:radeditor>
    <telerik:radeditor runat="server" ID="RadEditor3" ToolProviderID="RadEditor1"></telerik:radeditor>
    ............

    Code-Behind:
    RadEditor2.ToolProviderID = "RadEditor1";
    RadEditor3.ToolProviderID = "RadEditor1";
    ............
