Module Walkthrough: Dialog Content Management in Advantage CSP



AdvantageModule is an user-control referred to as a "Module" that inherit from the specific class.  These controls provide the front-end expression of content.  When working with page-based "unstructured content", the information is supplied to the control based on an associated user-control that is registered with the module.

The associate control is referred to as a "Dialog".  A dialog is an usercontrol that inherits from "AdvantageAttributeControl".  Information is passed between the objects using the "Attributes" property of the controls of type "AdvantageAttributes".  

Dialog control

  • Information is stored to the "Attributes" property
  • Information is saved to the dialog using the "SaveDataToObject()" method.
  • Information is loaded into the dialog using the "LoadDataFromObject(AdvantageAttributeArgs e)" method.


  • Information is retrieved using the "Attributes" property

Steps Intro

This guide provides a step-by-step walkthrough for creating an "AdvantageModule" with an associated dialog (AdvantageAttributeControl) designed to manage page-based content. This content refers to any data that is not used elsewhere in your application and only available in the page it has been created.

1. Create an AdvantageModule

The first step in the process is to create a front-end expression user-control that inherits from AdvantageModule.

2. Develop a Dialog Control

The first step in the process is to create an admin data entry user-control that inherits from AdvantageAttributeControl.

3. Binding information that needs to be passed from Dialog to Module

  • Using the control.ascx file create the html control elements
  • In the control.ascx.cs file complete the methods "LoadDataFromObject(AdvantageAttributeArgs e)" and "SaveDataToObject()" storing/retrieving the "Attributes" information to be passed to the expression module.

4. Retrieving Information stored from Dialog to Module

  • Using the control.ascx file create the html display elements
  • In the control.ascx.cs retrieve the "Attributes" information to be passed from the dialog module and bind to the appropriate element.


5.Register the Module/Dialog

The final step in creating an module  is to register within the system. Registration makes the mdoule available for use, linking it with the system's backend and frontend components.

By following these steps—you can effectively set up an AdvantageModule for managing page content.


Storing Data - Attributes

Understanding AdvantageAttributes

methods & properties

Passing data between the administrative portal and the front end expression is used via the AdvantageAttributes. 

  • Storing information is done via the "Add" method.  This method is overloaded allowing for native datatypes, as well as any class object that is serializable.
  • Information is retrieved via the "GetAttribute" method.  This method is overloaded allowing for native datatypes, as well as any class object that is serializable.

Storage Object (Optional)

The attributes from the dialog may be stored directly, however developers may find it coinvent and easier to code if you store to a class.  The class must be serializable to be used.


namespace AdvantageClient

    public enum eContentCardLayout
    {   //If french, it will pickup the Localized entry, otherwise default
        [Description("Side by Side")]
        [LocalDescription("fr", "Côte à côte")]
        SideText =0,
        [LocalDescription("fr", "Below")]
        BelowText = 1,
        [LocalDescription("fr", "Superposition-petit")]
        OverlayTextSmall = 2,
        [LocalDescription("fr", "Superposition-grande")]
        OverlayTextLarge = 3


    public class ContentCard
        public string Content { get; set; }
        public int Id { get; set; } 
        public string Category { get; set; }
        public eCategoryDisplay CategoryDisplay { get; set; }
        public string Heading { get; set; }
        public string SubHeading { get; set; }
        private AdvantageImage _image = null;
        public bool IsActive { get; set; } = true;
        public int SortOrder { get; set; }

        /// <summary>
        /// Get the image, and create a default with correct sizes if it doesn't exist
        /// </summary>
        /// <value>The image.</value>
        public AdvantageImage Image
                if (_image == null) _image = LoadAdvantageImage();
                return _image;
                _image = value;

        public eContentCardLayout CardLayout { get; set; } = eContentCardLayout.SideText;
        public string Url { get; set; }

        private AdvantageImage LoadAdvantageImage()
            var advantageImage = new AdvantageImage();
            advantageImage.AddImageElement(new AdvantageImageElement()
                ImageName = "Card Image",
                ImageSizeName = "Content Card"
            advantageImage.DefaultElementName = "Image";

            return advantageImage;


Create A Dialog Control

The dialog control provides the data-entry screen for the AdvantageModule front-end display.

Create new User control that inherits from AdvantageAttributeControl

  Add a html binding in the .ascx file.



<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ContentCardDialog.ascx.cs" Inherits="AdvantageClient.Modules_ContentCardDialog" %>

    <div class="form-row">                
        <label>Text Layout</label>
        <asp:DropDownList ID="ddlLayout" runat="server">
    <legend>Content Card</legend>

    <div class="form-row">    
        <asp:TextBox runat="server" ID="txtCategory"></asp:TextBox>
    <div class="form-row">                
        <label>Category Color</label>
        <asp:DropDownList runat="server" id="ddlCategoryColor"/>               
    <div class="form-row">    
        <asp:TextBox runat="server" ID="txtHeading"></asp:TextBox>
    <div class="form-row">    
        <asp:TextBox runat="server" ID="txtSubheading"></asp:TextBox>
    <div class="form-row btnAvailable">
        <label>Navigation Url</label>
        <advantage:AdvantageSelectorLink runat="server" ID="lnkUrl" />

    <div class="form-row btnImageAvailable">
        <advantage:AdvantageSelectorImage runat="server" ID="imgSelector"  />
    <div class="form-row">    
        <Advantage:AdvantageEditor runat="server" id="edtContent" UseFieldSet="False"  Height="300px"></Advantage:AdvantageEditor>


Bind html control content to the attributes.


namespace AdvantageClient

     public partial class Modules_ContentCardDialog : AdvantageAttributeControl

        /// <summary>
        /// Loads the data from object if it has been set, otherwise creates a new object.
        /// </summary>
        /// <param name="e">AdvantageAttributeArgs containing system information about the domain, language, etc.</param>
        protected override void LoadDataFromObject(AdvantageAttributeArgs e)
            var myObject =(Attributes.GettAttribute<ContentCard>("ContentCard"));
            if (myObject == null)
                myObject = new ContentCard();
                myObject.CardLayout = eContentCardLayout.SideText;
            ClientHelper.Enum_SetDropDownList<eContentCardLayout>(ddlLayout, myObject.CardLayout);
            ClientHelper.Enum_SetDropDownList(ddlCategoryColor, myObject.CategoryDisplay);
            txtCategory.Text = myObject.Category;
            txtHeading.Text = myObject.Heading;
            txtSubheading.Text = myObject.SubHeading;
            edtContent.Content= myObject.Content;

        /// <summary>
        /// Converts to object and saves it for later use in the front-end
        /// </summary>
        protected override void SaveDataToObject()
            var myObject = new ContentCard();

            myObject.CardLayout = ClientHelper.Enum_GetDropDownList<eContentCardLayout>(ddlLayout);
            myObject.CategoryDisplay = ClientHelper.Enum_GetDropDownList<eCategoryDisplay>(ddlCategoryColor);

            myObject.Category = txtCategory.Text;
            myObject.Heading = txtHeading.Text;
            myObject.SubHeading = txtSubheading.Text;
            myObject.Image = imgSelector.GetAdvantageImage();
            myObject.Url = lnkUrl.GetAdvantageLink();
            myObject.Content = edtContent.Content;

            Attributes.Add("ContentCard", myObject);

        public override bool ValidateSave(out string message)
            bool retval = true;
            message = string.Empty;

            if (string.IsNullOrEmpty(edtContent.Content))
                message = "Please enter Content.<br/>";
                retval = false;

            return retval;


Create Module

The module control retrieves data set in the dialog and provides the front-end display.

Create new User control that inherits from AdvantageModule

  Add a html binding in the .ascx file.
