    <p>so after a few weeks, i have got my head around asp.net mvc and have converted two webforms sites over. In addition to just the port, did some refactoring to have clean seperate of model, controller and view code. </p> <p>One pattern that i see that i think still needs improvement is the following and i would like advice or feedback on these items as i am not sure how bad these smells are.</p> <ol> <li><p>Problem: HTML rendering knowledge in your controller - its very easy to have your business logic generate a bunch of HTML and shove it in ViewData and then have your view be a bunch of code that looks like this:</p> <p>`&lt;%= Html.Encode(ViewData["Title"]) %></p> <p>`&lt;%= Html.Encode(ViewData["Content"]) %></p> <p>`&lt;%= Html.Encode(ViewData["Footer"]) %></p></li> </ol> <p>What is the best solution for this? I obviously want to avoid this logic in my view? Should i shove the data down to the client and have this "rendering" logic in HTMLHelper classes</p> <p>I end up with code like this in the controller class that builds up HTML tables . .</p> <pre><code>Stringbuilder gridBuilder = new StringBuilder(); while (index &lt; objDS.Count) { // start of table row gridBuilder.AppendLine("&lt;tr align=\"center\"&gt;"); for (int column = 0; column &lt; numberOfColumns; column++) { if (index &lt; objDS.Count) { int record = (index) + ((objDS.CurrentPageIndex) * 12); DataRow dr = photosDataSet.Tables[0].Rows[record]; gridBuilder.AppendLine("&lt;td width=\"187.5\" valign=\"top\"&gt;"); int pictureNumber = Convert.ToInt32(dr.ItemArray[0].ToString()); string picnum = pictureNumber.ToString().PadLeft(3, '0'); int picNumberlink = pictureNumber - 1; string image = "/pics/" + AlbumName + "/Thumbnails/" + AlbumName + "-pic" + picnum + ".jpg"; gridBuilder.AppendLine("&lt;a id=\"picLinks_" + record + "\" class=\"picLinks\" href=''&gt;&lt;img class=\"instant ishadow50\" src=\"" + image + "\"&gt;&lt;/img&gt;&lt;/a&gt;"); gridBuilder.AppendLine("&lt;br/&gt;"); gridBuilder.AppendLine(dr.ItemArray[1].ToString()); gridBuilder.AppendLine("&lt;/td&gt;"); } index++; } gridBuilder.AppendLine("&lt;/tr&gt;"); } gridBuilder.AppendLine("&lt;/table&gt;"); ViewData["Content"] = gridBuilder.ToString(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
