How to pass content of the editor to controller

Hi, I need help.

I'm working with asp.net Core 1.0 RC1 and the Telerik UI for ASP.NET MVC Q2 2016 with latest .714 patch

I would like to pass the content of an editor to my controller when clicking on a button without use of a model.

My View

<p>

<a asp-action="SaveScreen" asp-route-strValue="???????" asp-route-strMessage="My Message" id="#LINE1_SCR" SaveScreen" class="btn btn-primary">Save</a>

</p>

<div>

@(Html.Kendo().Editor()

.Name("LINE1_SCR")

.Tools(tools => tools.Clear().Bold().FontName().ForeColor().BackColor())

.Tag("DivLine")

.Value(@<text><p>Content of the editor</p></text>)

)

</div>

My controller

public async Task<IActionResult> SaveScreen(string strMessage)

    {

    var strControllerMessage = strMessage;

    return View();

    }

As you can see I pass parameters using the "asp-route..." razor syntax feature of asp.net core.

But I don't find any way to use the right syntax for passing the content of the editor in the "strValue" parameters of the push button.

Any help will be very appreciated.

Best regards.

But the validation error showing "The field Start Date must be a date.". The property StartDate is DateTime nullable field.

    .Update(update => update.Action("EditBHFormRR", "ReimbursementRequestProvider").Data("additionalInfoPath"))
    .Events(events => events.Error("errorpath"))
    .Group(groups => groups.Add(p => p.ExpenseTypeId))

    )
    )
   </div>
  </div>

now my requirement is to

change group client footer of group 1 to "Total Payment Requested"
change group clientfooter of group 2 to "Total Match Claimed"
TOTAL OF TOTAL AS "Total Billing Submitted" instead of ""

how to send GridSelectionMode.Multiple to the server

Hi,

I have a page with a grid with .Selectable(s => s.Type(GridSelectionType.Row).Mode(GridSelectionMode.Multiple)) and can select multiple lines. And I have a DropDownList.

What I want is to send an array of selected lines in the grid to the server AND the information of the dropdownlist.

If I want only one of this information I know how to do it but somewhere my ajax call gets corrupted.

If I have the following:

View:
var items= {};
var grid = $('#grid').data('kendoGrid');
var selectedElements = grid.select();
for (var j = 0; j < selectedElements.length; j++) {
var item = grid.dataItem(selectedElements[j]);
items['projectMoveModels[' + j + '].ID'] = item.ID;
items['projectMoveModels[' + j + '].DateString'] = item.Date;
items['projectMoveModels[' + j + '].EmployeeID'] = item.EmployeeID;
items['projectMoveModels[' + j + '].Hours'] = item.Hours;
}
$.ajax({
type: "POST",
data: items,
url: '@Url.Action("Move", "Project")',
}
})

And in the controller

public ActionResult Move(IList<ProjectMoveModel> projectMoveModels)

I do receive all selected lines in projectMoveModels.

But I want more data so I changed it to

var type = 1; //info from the dropdownlist
$.ajax({
type: "POST",
data: { projectMoveModels: items, type: type },

with in the controller

public ActionResult Move(IList<ProjectMoveModel> projectMoveModels, object type)

Now projectMoveModels will became null

How can I fix this error?

Thanks in advance

Grid inCell edit mode with server side validation.

Hi,

I search how to show server validation error in a Grid like the client validation (see image in attach file for example).

My grid is a InCell edit mode.

This is my grid code :

@(Html.Kendo().Grid<Mentorat.Models.Intervention>()

.Name("grid")

.Columns(columns =>

{

columns.Bound(c => c.Date_Intervention).Title("Date").Format("{0:yyyy/MM/dd HH:mm:ss}").Width(130).ClientGroupFooterTemplate("#= count # intervention(s)").ClientFooterTemplate("#= count # intervention(s)");

//columns.Bound(c => c.Date_Intervention).Width(130).Title("Date").ClientGroupFooterTemplate("#= count # intervention(s)").ClientFooterTemplate("#= count # intervention(s)").HtmlAttributes(new { @class = "templateCell" }).ClientTemplate((

//    @Html.Kendo().DateTimePicker().Name("date_#=No_Intervention#").Format("{0:yyyy/MM/dd HH:mm}").HtmlAttributes(new { data_bind = "value:Date_Intervention" }).ToClientTemplate()).ToHtmlString()

//);

columns.Bound(c => c.Duree_Intervention).Title("Durée (min.)").Width(70).ClientGroupFooterTemplate("Total : #= kendo.format('{0:0.00}', sum/60)# hrs").ClientFooterTemplate("Total : #= kendo.format('{0:0.00}', sum/60)# hrs");

columns.ForeignKey(c => c.No_Mentore_Intervention, (System.Collections.IEnumerable) ViewData["ListeMentor"], "No_Mentore", "NomComplet_Mentore").Title("Mentoré").Width(160).ClientGroupHeaderTemplate("#= getHeaderMentores(value,data)#");

columns.Bound(c => c.Description_Intervention).Title("Description").Width(300);

columns.Command(command => { command.Destroy(); }).Width(65);

})

.ToolBar(toolbar =>

{

toolbar.Create();

toolbar.Custom().Name("RepartirTemps").Text("Répartir").HtmlAttributes(new { id = "RepartirTemps", @class = "k-plus" }).Url("#");

toolbar.Save();

toolbar.Excel();

})

.Editable(editable => editable.Mode(GridEditMode.InCell))

.Pageable()

.Filterable(ftb => ftb.Mode(GridFilterMode.Menu))

.Groupable()

.Events(events => events.DataBound("onDataBound"))

.Events(events => events.Edit("onEdit"))

.DataSource(dataSource => dataSource

.Ajax()

.Events(e => e.Change("onChange"))

.Events(e => e.Error("onError"))

.Batch(true)

.PageSize(100)

.Model(model => model.Id(p => p.No_Intervention))

.Read(read => read.Action("Interventions_Read", "Interventions"))

.Create(create => create.Action("Interventions_Create", "Interventions"))

.Update(update => update.Action("Interventions_Update", "Interventions"))

.Destroy(destroy => destroy.Action("Interventions_Destroy", "Interventions"))

.ServerOperation(false) //nouveau....

.Aggregates(ag =>

{

ag.Add(p => p.Duree_Intervention).Sum();

ag.Add(p => p.Date_Intervention).Count();

})

)

This is my controller update code :

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult Interventions_Update([DataSourceRequest]DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<

Intervention> interventions)

{

var entities = new List<Intervention>();

if (interventions != null && ModelState.IsValid)

{

if (ValiderGrid(interventions))

{

foreach (var intervention in interventions)

{

var entity = new Intervention

{

No_Intervention = intervention.No_Intervention,

Date_Intervention = intervention.Date_Intervention,

No_Mentor_Intervention = (int) Session["intNoMentor"],

No_Mentore_Intervention = intervention.No_Mentore_Intervention,

Duree_Intervention = intervention.Duree_Intervention,

Description_Intervention = intervention.Description_Intervention

};

entities.Add(entity);

db.Interventions.Attach(entity);

db.Entry(entity).State = EntityState.Modified;

}

db.SaveChanges();

}

var resultData = new[] { interventions };

return Json(resultData.AsQueryable().ToDataSourceResult(request, ModelState));

}

private Boolean ValiderGrid(IEnumerable<Intervention> interventions)

{

foreach (var intervention in interventions)

{

if(intervention.Date_Intervention == null)

{

ModelState.AddModelError("Date_Intervention", "Vous devez inscire une date.");

}

return ModelState.IsValid;

}

I add in attach file a capture of my action error return.

i tried lot of solution with the error events. Each solution have a loop with this property "e.errors.length" but .lenth is undefined.

it is posible to show server error in the gird like client side error? Or i can only print a error message in a popup or in a div?

Thank for your help!

[Solved] Splitter not initial/work well in panelbar when using partial view

hello,

I am drawing one page like this: In panelbar, load Splitter widget. When I put Splitter in partial view and use LoadContentFrom to load this partial view. Splitter will not initial/work well.

Here is part code:

1. PanelBar

      @(Html.Kendo().PanelBar()
          .Name("Panelbar1")
          .ExpandMode(PanelBarExpandMode.Multiple)
          .Items(panelbar =>
          {
              panelbar.Add().Text(N5Default.LABEL_MASTER_STRUCTURE).ImageUrl(@Url.Content("~/content/images/controltesting_panel1.png"))
                  .Expanded(false).LoadContentFrom("SplitterPartial", "Admin");
          })
)

2. Splitter

@(Html.Kendo().Splitter()
      .Name("SplitterSample")
      .HtmlAttributes(new { style = "height:700px;top:-9px;" })
      .Orientation(SplitterOrientation.Vertical)
      .Panes(verticalPanes =>
      {
          verticalPanes.Add()
              .HtmlAttributes(new { id = "location-structure-top-pane" })
              .Scrollable(false)
              .Collapsible(true)
              .Content(
                Html.Kendo().Splitter()
                    .Name("LocationStructureHorizontalSplitter")
                    .HtmlAttributes(new { style = "height: 100%;" })
                    .Panes(horizontalPanes =>
                    {
                        horizontalPanes.Add()
                            .HtmlAttributes(new { id = "location-structure-left-pane" })
                            .Size("200px")
                            .Collapsible(true)
                            .Content("");
                        horizontalPanes.Add()
                            .Collapsible(true)
                            .HtmlAttributes(new { id = "location-structure-right-pane" })
                            .Content("");
                    }).ToHtmlString()
              );
          verticalPanes.Add()
              .HtmlAttributes(new { id = "location-structure-bottom-pane" })
              .Size("320px")
              .Collapsible(true)
              .Content("");
      })
   )

Anybody know why it does not work?

After I use Content to load Splitter and not use LoadContentFrom by partial view, it works.

The below code works well:

@(Html.Kendo().PanelBar()
          .Name("Panelbar1")
          .ExpandMode(PanelBarExpandMode.Multiple)
          .Items(panelbar =>
          {
              panelbar.Add().Text(N5Default.LABEL_MASTER_STRUCTURE).ImageUrl(@Url.Content("~/content/images/controltesting_panel1.png"))
                  .Expanded(false).Content(@<div>
                      @RenderSplitter()
                  </div>);
          })
)

@helper RenderSplitter()
{

@(Html.Kendo().Splitter()
.Name("SplitterSample")

.......

}

Anybody can help? Because I am drawing one complex page. I cannot put all widgets in one page. It will be hard to view. So I want to use partial view to load. Thanks in advance.

Mark

Does Kendo Validator exist as a replacement or supplement to jQuery Validator?

Does Kendo Validator exist as a replacement or supplement to jQuery Validator?

It feels wrong to have to instantiate a kendo validator whenever a form contains kendo form elements, as well as the default jQuery validator which contains some special rules associated with the form elements that Kendo doesn't provide.

Grid().DataSource

Hi,

I've over 500+ pages that almost has common DataSource definitions like:

......

.DataSource(dataSource => dataSource
.Ajax()
.PageSize(Constants.UI.GridPageSize)
.Events(events => events.Error(Constants.UI.GridErrorMethod))
.Model(model => model.Id(p => p.ID))
.Create(update => update.Action(Constants.UI.GridMethods.Create))
.Read(read => read.Action(Constants.UI.GridMethods.Read))
.Update(update => update.Action(Constants.UI.GridMethods.Update))
.Destroy(update => update.Action(Constants.UI.GridMethods.Delete))
)

I've made an extension (defined in here: http://www.telerik.com/forums/define-a-custom-html-kendo-extension-helper), but I also want to say .CustomDataSource() and manage in one place. How I can do that?

Thank you.
