title: When grid enters edit mode DateTime picker clears value
body: <p>I have a DateTime field bound to a grid. When the grid enters edit mode the date/time picker displays, but the value is cleared from it.  This forces the user to re enter the date/time.  Any idea why it value is cleared when the edit mode is triggered?</p>
  
  <pre><code>@(Html.Telerik().Grid&lt;ExpenseGridModel&gt;()
      .DataBinding(dataBinding =&gt; dataBinding.Ajax()
          .Select("ExpenseAjaxBinding", "ExpenseEntry")
          .Update("ExpenseUpdate", "ExpenseEntry")
      )
      .Name("ExpensesGrid")
      .DataKeys(keys =&gt; keys.Add(r =&gt; r.id))
      .Columns(columns =&gt;
          {
              columns.ForeignKey(o =&gt; o.categoryId, Model.expenseCategories, "Id", "Name");
              columns.ForeignKey(o =&gt; o.typeId, Model.expenseTypes, "Id", "Name");
              columns.Bound(r =&gt; r.date);
              columns.ForeignKey(o =&gt; o.classId, Model.expenseClasses, "Id", "Name");
              columns.Bound(r =&gt; r.description);
              columns.Bound(r =&gt; r.amount);
              columns.Command(commands =&gt;
                      commands.Edit()                                          
              );
          })
           )
