Regency Software | Sort BlogEngine.net Link List by Title

Here is a code snippet to sort Blogengine.net link list.

You want to modify the following C# file: BlogEngine\BlogEngine.NET\Custom\Widgets\LinkList\widget.ascx.cs

Listed below is the original code from the method: LoadWidget()

//-----------------
//Orginal code
//-----------------              
foreach (XmlNode node in links)
{
    var a = new HtmlAnchor();

    if (node.Attributes != null)
    {
        if (node.Attributes["url"] != null)
        {
            a.HRef = node.Attributes["url"].InnerText;
        }

        if (node.Attributes["title"] != null)
        {
            a.InnerText = node.Attributes["title"].InnerText;
        }

        if (node.Attributes["newwindow"] != null &&
            node.Attributes["newwindow"].InnerText.Equals("true", StringComparison.OrdinalIgnoreCase))
        {
            a.Target = "_blank";
        }
    }

    var li = new HtmlGenericControl("li");
    li.Controls.Add(a);
    this.ulLinks.Controls.Add(li);
}

Replace the code above with the following:

The updated code starts at...

//--------------------------------------------------
//1. Put links in a table, the sort and process
//--------------------------------------------------

public override void LoadWidget()
{
    var settings = this.GetSettings();
    var doc = new XmlDocument();

    if (settings["content"] != null)
    {
        doc.InnerXml = settings["content"];
    }

    var links = doc.SelectNodes("//link");

    if (links == null)
    {
        return;
    }

    if (links.Count == 0)
    {
        this.ulLinks.Visible = false;
    }
    else
    {
        //--------------------------------------------------
        //1. Put links in a table, the sort and process
        //--------------------------------------------------
        DataTable DtLinks = new System.Data.DataTable();
        DtLinks.Columns.Add("URL", typeof(String));
        DtLinks.Columns.Add("Title", typeof(String));
        DtLinks.Columns.Add("Target", typeof(String));

        //--------------------------------------------------
        //2. Add to table
        //--------------------------------------------------
        DataRow dr = DtLinks.NewRow();

        foreach (XmlNode node in links)
        {
            if (node.Attributes != null)
            {
                //Create Row and Default Values
                dr = DtLinks.NewRow();
                dr["URL"] = string.Empty;
                dr["Title"] = string.Empty;
                dr["Target"] = string.Empty;

                if (node.Attributes["url"] != null)
                {
                    dr["URL"] = node.Attributes["url"].InnerText.ToString();
                }

                if (node.Attributes["title"] != null)
                {
                    dr["Title"] = node.Attributes["title"].InnerText.ToString();
                }

                if (node.Attributes["newwindow"] != null &&
                    node.Attributes["newwindow"].InnerText.Equals("true", StringComparison.OrdinalIgnoreCase))
                {
                    dr["Target"] = "_blank";
                }

                DtLinks.Rows.Add(dr);
            }                    
        }                

       DtLinks.AcceptChanges();

       //--------------------------------------------------
       // 3. Loop through table and add to list item.
       //--------------------------------------------------
       DataView View = DtLinks.DefaultView;
       View.Sort = "Title";

       foreach (DataRowView row in View)
       {
           var a = new HtmlAnchor();
           a.HRef = row["URL"].ToString();
           a.InnerText = row["Title"].ToString();

           if (row["Target"].ToString() != string.Empty) a.Target = row["Target"].ToString();

           var li = new HtmlGenericControl("li");
           li.Controls.Add(a);
           this.ulLinks.Controls.Add(li);
       }            
    }
}
