Webpart to show Sitecollections/Subwebs

This Webpart will show Sitecollections from the current Webapplication or Subwebs from the current web.

In the Webpart properties you can choose what the Webpart will show.

It uses the Logo URL of websites, if they are specified. The description of the website will show up as tooltip.

I am using the RepeatedControls class to build the items. This class really makes it easy to add entries by moving the layout functionality into an own class.

Create a new class

class Links : RepeatedControls

 private readonly Table _Table;


Add a default constructor

In the constructor, you can modify the header, footer and separator for the entries.

public Links()

 HeaderHtml = "
FooterHtml = <span class=str>"</div>"</span>;
 SeparatorHtml = string.Empty;
 _Table = new Table {CssClass = "ms-itemstatic", CellSpacing = 0};
_Table.Style.Add(<span class=str>"padding"</span>, <span class=str>"3px 0px 3px 4px"</span>);


Add elements to the class

public void AddHyperLink(string text, string toolTip, string url, string imageUrl)

 var row = new TableRow {Height = Unit.Pixel(16)};
row.Attributes.Add(<span class=str>"title"</span>, SPHttpUtility.HtmlEncode(toolTip));
 row.Attributes.Add("onmouseover", "this.className='ms-itemhover';MMU_PopMenuIfShowing(this);");
row.Attributes.Add(<span class=str>"onmouseout"</span>, <span class=str>"this.className='ms-itemstatic';"</span>);
 row.Attributes.Add("onclick", "window.navigate('" + url + "');");
 var imageCell = new TableCell();
imageCell.HorizontalAlign = HorizontalAlign.Center;
 imageCell.Style.Add("padding-top", "1px");
var image = <span class=kwrd>new</span> Image
AlternateText = <span class=kwrd>string</span>.Empty,
 ImageUrl = (!string.IsNullOrEmpty(imageUrl) ? imageUrl : "/_layouts/images/setrect.gif")
var linkCell = <span class=kwrd>new</span> TableCell
VerticalAlign = VerticalAlign.Top,
 Width = Unit.Percentage(100),
CssClass = <span class=str>"ms-descriptiontext"</span>
linkCell.Style.Add(<span class=str>"padding-left"</span>, <span class=str>"3px"</span>);
 var link = new Label {Text = SPHttpUtility.HtmlEncode(text)};


Now that we have our own class to deal with navigation entries, we will use it.


var links = new Links();



To add items, simply type:

links.AddHyperLink(objects.Title, objects.Description, objects.Url, objects.ImageUrl);


Why would you use your own class derived from RepeatedControls?

  • don’t mix functions and layout
  • keep you code small
  • improve the readability of your code

If you want to use this solution, you have to install the WSPBuilder Visual Studio extensions!
