[CLOSED] MVC conditional validation not showing error

[susanz]

Hi, I have a grid that uses popup editor to insert new row. I created a RequiredIfValidator and attach it to model field :

public Class JobModel
{

        [DisplayName("Email")]
        public bool SendEmailFlag { get; set; }

        [DisplayName("Subject")]
        [StringLength(80)]
        [RequiredIf("SendEmailFlag", true, ErrorMessage = "You must specify the Email Subject if Send Email is true")]
        public string EmailSubject { get; set; }

}

cshtml:

@(Html.Kendo().Grid<JobModel> () 
         .Name("JobGrid")
         .HtmlAttributes(new { style = "height:700px;" })
         .Editable(editing => editing.Mode(GridEditMode.PopUp)
                                     .CreateAt(0)
                                     .DisplayDeleteConfirmation (false))
         .ToolBar(toolbar => toolbar.Create().Text("Add"))
         .Columns(columns =>
         {
             columns.Bound(e => e.JobID).Hidden(true);
             columns.Bound(e => e.JobDesc);
             columns.Bound(e => e.SendEmailFlag)
                  .HeaderTemplate(@<text>
                      <a href="#" data-toggle="tooltip" title="Email Notification Enabeld" tabindex ="-1" >
                           <img src = "Images/Email.icon.png" /> </a>                    
                      </text>
                  ).Width("4%")
                  .Filterable(false)
                  .ClientTemplate("<input type='checkbox' disabled='disabled' name='SendEmailFlag' #: SendEmailFlag? checked='checked' : '' # />")
                  .HtmlAttributes(new { style = "text-align:center" });
              columns.Bound(e => e.Runnable)
                  .HeaderTemplate(@<text>
                      <a href="#" data-toggle="tooltip" title="Ready to distribute -- has at least one group assigned." tabindex ="-1" >
                           <img src = "Images/ready.jpg" /> </a>                    
                      </text>
                 ).Width("4%")
                 .Filterable(false)
                 .ClientTemplate("<input type='checkbox' disabled='disabled' name='Runnable' #: Runnable? checked='checked' : '' # />")
                 .HtmlAttributes(new { style = "text-align:center" });
              columns.Bound(e => e.CreateBy);
              columns.Bound(e => e.LastModify).Format("{0:g}");
              columns.Template(x => { })
                .ClientTemplate("<a class='k-button' href='" + Url.Action("AddReport", "Job") + "/#=JobID#'>Assign Report</a> ");

              columns.Command(commands =>
              {
                  commands.Edit();
                  commands.Destroy();
                
              });
         })
        .Events (ev => 
            { ev.DataBound ("OnGridDataBound");
              ev.Edit("OnEdit");
            })
        .ClientDetailTemplateId("JobDetailTemplate")
        .DataSource(dataBinding => dataBinding.Ajax()
                .PageSize(20)
                .Model(model => 
                    { model.Id(p => p.JobID);
                      model.Field(p => p.JobID).DefaultValue(Guid.Empty);
                      model.Field(p => p.CreateTime).Editable(false);
                      model.Field(p => p.LastModify).Editable(false);
                    })
                .Read(read => read.Action("Job_Read", "Job"))
                .Sort(sort => sort.Add(job => job.JobDesc))
                .Update(update => update.Action("Job_Update", "Job"))
                .Create(update => update.Action("Job_Insert", "Job"))
                .Destroy(update => update.Action("Job_Delete", "Job"))
                )
        .Pageable(p => p.Enabled(true).ButtonCount(5).PageSizes(new int[] {20, 40, 60, 100}).Refresh(true))
        .Filterable(f => f.Extra(false))
        .Resizable(resize => resize.Columns(true))
        .Sortable()
        .Scrollable()
       )

The Validate() returns error but it never show the error under the filed like other Required validator.
Did I missed something? what is best way to do conditional validation? I am using MVC 4
Thanks

Hi @susanz,

Html.Kendo().Grid - is that Telerik?
