  You achieve this by doing like so:
  
  

  @( Html.Telerik().Grid(Model)

      .Name("Grid")

      .ToolBar(commands => commands.Insert())

      .Columns(columns =>

      {

    

          if (item.Prop == DateTime.MinValue)

          {

              columns.Bound(o => o.prop);

          }

   

      ...

      }

  ...

  )

  Thanks for the reply, but apparently the item element its not available at that point:
  
  Compiler Error Message: CS0103: The name 'item' does not exist in the current context 
  
  here's my code
  
      Html.Telerik().Grid((IEnumerable<Movies>)ViewBag.MoviesSet)
          .Name("grid")
          .DataKeys(dk => dk.Add(k => k.Id))
          .Columns(columns =>
                       {
                           if (item.State == "x")
                           {
                               columns.Bound(pp => pp.State);
                              
                           }
                           columns.Bound(pp => pp.Id).Hidden(true);
                           columns.Bound(pp => pp.Name);
                       })
          .Pageable()
          .Sortable()
          .Selectable()
          .Groupable()
          .ClientEvents(events => events.OnRowSelect("onRowSelected"))
          .Render();

  I see now what you're trying to do, but i dont understand why. But in the spirit of answering your question, this is how I think you'd answer it.
  
  

  .Columns(columns =>
           {
                 columns.Bound(pp => pp.State);
           })
.CellAction(cell =>

          {

              if (cell.Column.Title == "State")

              {

                  if (cell.DataItem.State != null)

                  {

                      if (cell.DataItem.State != "x")

                      {

                          cell.HtmlAttributes["style"] = "display:none";

                      }

                  }

              }

          })

  what i was trying to accomplish was showing some data depending on a condition:
  
  

  Id	Name	State
  1	Terminator	Active
  2	Terminator 2
  3	Terminator 3	Inactive

  
  I think the best way it to sue the hidden() method, am i right ??

  Using the .CellAction didn't work?
  
  If it broke your grid, try using "visibility:hidden" instead of "display:none"
