Kendo Grid Server Side Paging With Model Binding

Hi I have a kendo grid in my partial view.
And I have bind a model as the grid data source. And mention that my grid don't have a Read method. Instead of read method I have use the model.
Here is my view..
@model Project.MVC.Areas.Razor.Models.CustomerListModel

<div id="dvResultGrid">
@(Html.Kendo().Grid<Portal.Application.BoundedContext.ScreenPop.Dtos.Customer>(Model.CustomerList)
.Name("grdWindowResults")

.Columns(columns =>
{
columns.Bound(x => x.Name1).Visible(true);
columns.Bound(x => x.Name2).Visible(true);
columns.Bound(x => x.ContactName);
columns.Bound(x => x.BillingAddress1);
})
.Pageable()
.Sortable(x => x.Enabled(false))
.Scrollable(x => x.Height("auto"))
.Selectable(selectable => selectable.Mode(GridSelectionMode.Single))
.Reorderable(reorder => reorder.Columns(true))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(false)
.PageSize(5)
.Model(model =>
{
model.Id(p => p.CustomerId);

})
)
)
</div>
And what I have to do is, I need to do server-side paging for my grid. How can I do that with out a read method. Is there any option?

EditorFor Validation Styles

I am using the Kendo.EditorFor() control to display editors as I loop through a List of objects. I have server-side validation in play and when I submit the form, it correctly identifies that the fields are not filled in. However, the appropriate classes are not added to any of the HTML elements that are returned back to the browser, and therefore there is no visual indicator of which editor(s) have not been filled in.

Here's a copy of my HTML:

    @using (Html.BeginForm("SaveSelfAssessment", "Accreditation", FormMethod.Post, new { id = "form", enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(false, "The following errors occurred:", new { @class = "error_box" })

        <input type="hidden" id="Id" name="Id" value="@Model.Id" />
        <input type="hidden" id="StartingId" name="StartingId" value="@Model.StartingId" />

        for (int i=0; i<Model.ApplicationSelfAssessments.Count; i++)
        {
            @Html.HiddenFor(m => m.ApplicationSelfAssessments[i].Id)
            @Html.HiddenFor(m => m.ApplicationSelfAssessments[i].Type)

            <div class="@Model.ApplicationSelfAssessments[i].Type">
            @if (Model.ApplicationSelfAssessments[i].Type == "supplementalinformation")
            {
                <h2>Supplemental Information</h2>
            }
                @Html.Raw(Model.ApplicationSelfAssessments[i].Text)
            </div>

            if (Model.ApplicationSelfAssessments[i].Type == "question")
            {
                <div>@(Html.Kendo().EditorFor(m => m.ApplicationSelfAssessments[i].Answer)
                          .Encode(false)
                          .Tools(tools => tools
                                  .Clear()
                                  .Bold()
                                  .Italic()
                                  .Underline()
                                  .InsertUnorderedList()
                                  .InsertOrderedList()
                                  .Indent()
                                  .Outdent()
                            )
                        )
                </div>
            }
        }

        <p>
            <input type="button" class="k-button k-button-icontext" value="Previous" onclick="window.location = '@Model.PreviousUrl';" />
            <input type="submit" class="k-button k-button-icontext" value="Next" />
        </p>
    }

And my model contains the following Validate method:

        public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
        {
            if (Type == SelfAssessmentType.Question.ToString().ToLower() && String.IsNullOrWhiteSpace(Answer))
            {
                yield return new ValidationResult("Answer is required", new [] { "Answer" });
            }
        }

If I turn the editor into a textarea, the input-validation-error class is added to the textarea. Is there a way I can get this to work using the Kendo.EditorFor tool?

Thank you,

Rachael

Problems with Q1 2014 upgrade

I just installed Q1 2014 of the MVC controls. Ran the wizard to update my project and received no errors. (the app was previously running Q2 2013)

Groups doesn't work for grid with VS 2013

Hi guys,

I simply modified the last version of samples (grid/index.chtml), in order to test a grouping configuration as described in documentation.
But the Groups property does not exist.
Here the code below:

@model Kendo.Mvc.Examples.Models.HeaderTemplateViewModel
@{using (Html.BeginForm())
{
    @(Html.Kendo().Grid(Model.Products)
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Template(@<text>
                     <input name="selectedProducts" type="checkbox" title="select product" value="@item.ProductID"
                     @{
                         if (Model.SelectedProducts.Any(p => p.ProductID == item.ProductID))
                         {
                            @("checked=checked")
                         }
                     }/>

Four grids on Page

And I have controller with four actions

public ActionResult GetNewSuppliers([DataSourceRequest] DataSourceRequest request)

{

var data = service.GetSuppliersByStatus(SupplierStatusEntity.SavedDraft).Where(s => string.Equals(s.PINUserName, User.Identity.Name, StringComparison.OrdinalIgnoreCase)).Select(SupplierConverter.Convert);

return Json(data.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

public ActionResult GetSubmittedSuppliers([DataSourceRequest] DataSourceRequest request)

{

var data = service.GetSuppliersByStatus(SupplierStatusEntity.Submitted).Where(s => s.PINUserName == User.Identity.Name).Select(SupplierConverter.Convert);

return Json(data.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

public ActionResult GetApprovedSuppliers([DataSourceRequest] DataSourceRequest request)

{

var data = service.GetSuppliersByStatus(SupplierStatusEntity.Approved).Where(s => string.Equals(s.PINUserName, User.Identity.Name, StringComparison.OrdinalIgnoreCase)).Select(SupplierConverter.Convert);

return Json(data.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

public ActionResult GetRejectedSuppliers([DataSourceRequest] DataSourceRequest request)

{

var data = service.GetSuppliersByStatus(SupplierStatusEntity.Rejected).Where(s => s.PINUserName == User.Identity.Name).Select(SupplierConverter.Convert);

return Json(data.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

But It does not work.

Is it possible to implement this variant?

Multiselect and form, not sending values back

Hi guys,
I have a mvc view (still a pretty standard one) to edit one of my entities..

@using (Ajax.BeginForm("Edit", "Role",

new AjaxOptions() { HttpMethod = "POST", UpdateTargetId = "ajaxRoleEditForm", OnSuccess = "OnRoleUpdated" }))

{

@Html.AntiForgeryToken()

@Html.ValidationSummary(true)

<fieldset>

<legend>ROLE_T005</legend>

@Html.HiddenFor(model => model.ID)

<div class="editor-label">

@Html.LabelFor(model => model.Name)

</div>

<div class="editor-field">

@Html.EditorFor(model => model.Name)

@Html.ValidationMessageFor(model => model.Name)

</div>

<div class="editor-label">

@Html.LabelFor(model => model.Description)

</div>

<div class="editor-field">

@Html.EditorFor(model => model.Description)

@Html.ValidationMessageFor(model => model.Description)

</div>

<div class="editor-label">

@Html.LabelFor(model => model.Functions)

</div>

<div class="editor-field">

@Html.EditorFor(model => model.Functions)

</div>

<p>

<input type="submit" value="Save" />

</p>

</fieldset>

}

the model is a view model because the actual table (using EF) has a cross table to a child entity and I dont want to bother with it.
so my wiew model is:

public class RoleViewModel

{

public int ID { set; get; }

public string Name { set; get; }

public string Description { set; get; }

[UIHint("FunctionMultiSelectTemplate")]

public IList<FUNCTION_T008> Functions { set; get; }

}

and the custom template for the list of functions is:

@model IList<Lme.WQ2.AccessControl.Dal.FUNCTION_T008>

@(Html.Kendo().MultiSelect()

.Name("FunctionMultiSelectTemplate")

.Placeholder("Select functions...")

.BindTo(ViewBag.Functions)

.Value(Model)

.DataTextField("NAME")

.DataValueField("ID")

)

at last my action looks like:

public ActionResult Edit(int id = 0)

{

ROLE_T005 role_t005 = db.ROLE_T005

.Include(x => x.ROLE_FUNCTION_T010)

.Include(x => x.ROLE_FUNCTION_T010.Select(y => y.FUNCTION_T008))

.SingleOrDefault(x => x.ID == id);

RoleViewModel roleViewModel = new RoleViewModel()

{

ID = role_t005.ID,

Name = role_t005.NAME,

Description = role_t005.DESCRIPTION,

Functions = role_t005.ROLE_FUNCTION_T010.Select(x => x.FUNCTION_T008).ToList()

};

ViewBag.Functions = db.FUNCTION_T008.AsEnumerable();

if (role_t005 == null)

{

return HttpNotFound();

}

return View(roleViewModel);

}

now, when I hit the save button of the view, the function list is always null or empty...
What am I doing wrong?
Thanks
Fabio

[Solved] Use <span> in a grid column value

I'm trying to change the color of some column values by setting the data value of these to "<span class='redcolor'>value</span>"

This doesn't work as it just displays the span and everything as text in the column even though the table element renders as
<td role="gridcell"><span class='redcolor'>value</span></td>

Is there a different way to accomplish this? Thanks.

[Solved] MVC Timepicker

All,

Is it possible to have a time picker with more than one column? My time selection can run all day, normally at 30-minute intervals and I would hate to have to scroll down like that. With the asp.NET version there is a property I can set, but not so here. I imagine it would be done with templating, but I am not sure how that would work.
I have the following definition:

<label for="TxtCloseTime">Close:</label>
@(Html.Kendo().TimePicker().Name("TxtCloseTime")
.Events(e => e.Change("VerifySelection"))
.Interval(30)
.Animation(a => a.Open(o => o.Expand(ExpandDirection.Vertical))))

Thanks,

Sean~
