I m trying to do a simple If Else within a foreach with this code      var count   0  foreach  var item in Model        if  count     2    0                   lt tr class  alt-row  gt        else               lt tr gt                 lt td gt               Html DisplayFor modelItem   gt  item Title           lt  td gt           lt td gt               Html Truncate item Details  75           lt  td gt           lt td gt               lt img src   Url Content    Content Images Projects    item Images Where i   gt  i IsMain    true  Select i   gt  i Name  Single                     alt   item Images Where i   gt  i IsMain    true  Select i   gt  i AltText  Single    class  thumb    gt           lt  td gt           lt td gt               Html ActionLink  Edit    Edit   new   id item ProjectId                   Html ActionLink  Details    Details   new   id   item ProjectId                   Html ActionLink  Delete    Delete   new   id item ProjectId             lt  td gt       lt  tr gt        I get a parse error  Encountered end tag  tr  with no matching start tag   Are your start end tags properly balanced    Seems like the if statement doesn t wanna  work

A little bit off topic maybe  but for modern browsers  IE9 and newer  you can use the css odd even selectors to achieve want you want   tr nth-child even       your alt-row stuff     tr nth-child odd       the other rows        or  tr      all table rows      tr nth-child even       your alt-row stuff

I would just go with    lt tr   if  count     2    0   lt text gt class  alt-row  lt  text gt    gt    Or even better    lt tr class  alt-row  count     2   gt    this will give you lines like    lt tr class  alt-row0  gt   lt tr class  alt-row1  gt   lt tr class  alt-row0  gt   lt tr class  alt-row1  gt

To get rid of the if else awkwardness you could use a using block          var count   0      foreach  var item in Model                using Html TableRow new    class    count     2    0     alt-row                                  lt td gt                   Html DisplayFor modelItem   gt  item Title               lt  td gt               lt td gt                   Html Truncate item Details  75               lt  td gt               lt td gt                   lt img src   Url Content    Content Images Projects    item Images Where i   gt  i IsMain    true  Select i   gt  i Name  Single                         alt   item Images Where i   gt  i IsMain    true  Select i   gt  i AltText  Single    class  thumb    gt               lt  td gt               lt td gt                   Html ActionLink  Edit    Edit   new   id item ProjectId                       Html ActionLink  Details    Details   new   id   item ProjectId                       Html ActionLink  Delete    Delete   new   id item ProjectId                 lt  td gt                      Reusable  element that make it easier to add attributes     Block is take from http   www codeducky org razor-trick-using-block  public class TableRow   Block       private object  htmlAttributes      private TagBuilder  tr       public TableRow HtmlHelper htmlHelper  object htmlAttributes    base htmlHelper                 htmlAttributes   htmlAttributes             public override void BeginBlock                  tr   new TagBuilder  tr             tr MergeAttributes HtmlHelper AnonymousObjectToHtmlAttributes  htmlAttributes            this HtmlHelper ViewContext Writer Write  tr ToString TagRenderMode StartTag               protected override void EndBlock                 this HtmlHelper ViewContext Writer Write  tr ToString TagRenderMode EndTag              Helper method to make razor syntax clearer   public static TableRow TableRow this HtmlHelper self  object htmlAttributes        var tableRow   new TableRow self  htmlAttributes       tableRow BeginBlock        return tableRow

Just use this for the closing tag        lt  tr gt    And leave your if else as is       Seems like the if statement doesn t wanna  work    It works fine  You re working in 2 language-spaces here  it seems only proper not to split open close sandwiches over the border
