When editing a form with data, when I click the control to "EDIT" my saved date range selection it's opening on Todays date instead of my date range selection.

Any idea how to resolve this?

How can I tell what input validator.validate() is failing on?

I have a form Razor in .NET Core that I have attached a Kendo Validator to. When I submit the form validator.validate() is returning false but none of the inputs on the form are displaying a validation error. How can I tell what validations are failing when validator.validate() returns false?

Razor Form

<form id="editQuestionsForm" method="post">

<input asp-for="Input.InspectionQuestionId" type="hidden" />

<div class="row">

<div class="col-md-12">

<div class="form-group">

<label asp-for="Input.InspectionSectionId"></label><br />

<kendo-combobox name="inspectionSection" style="width: 500px;"

for="Input.InspectionSectionId"

placeholder="Select Section"

datatextfield="Text"

datavaluefield="Value"

bind-to="Model.InspectionSections">

<popup-animation>

<open duration="500" />

<close duration="500" />

</popup-animation>

</kendo-combobox><br />

<span asp-validation-for="Input.InspectionSectionId" class="text-danger"></span>

</div>

<div class="row">

<div class="col-md-12">

<div class="form-group">

<label asp-for="Input.QuestionTextForForm"></label><br />

<textarea asp-for="Input.QuestionTextForForm" class="form-control-textarea"></textarea><br />

<span asp-validation-for="Input.QuestionTextForForm" class="text-danger"></span>

</div>

</form>

JavaScript

var validator = $("#editQuestionsForm").kendoValidator().data("kendoValidator");

function validateSave() {

if (validator.validate()) {

$('#editQuestionsForm').submit();

} else {

bootstrapWarningsMessage("There was an error submitting the form.");

}

return true;

}

Object does not support method kendoGrid

(It's a trial version)

Impossible to display data.

Data are correctly supplied in my form (see DOM capture)

But there is an error : L’objet ne gère pas la propriété ou la méthode « kendoGrid »

JS are the same than in examples.

[Solved] Initially hidden window causes flickering

I have a window in my _Layout.cshtml which I have initially set to visible="false". When I load or refresh the main page, I get a flickering, such that you can momentarily see the window text and button. I'm using a tag helper if that makes any difference.

The following is the _Layout.cshml file. The rest of the solution is just the standard Telerik ASP.Net Core template using ASP.Net Core 2019.2.514 controls on .Net Core 2.2.

Grid Background color

Currently my grid background is the light gray, and the rows alternate between light and dark. Is it possible to get the unused portion of the grid to be a different color, while leaving the row alternating colors alone?

Multi editor popup

Hello,

I have a grid with derived objects and I would like to open different edit popup for each type of child object.

I'll give a simplified example:

Models:

public class Product

{

public string Label { get; set; }

}

public class TypeA: Product

{

public string PropA { get; set; }

}

public class TypeB: Product

{

public int PropB { get; set; }

}

public class Order

{

public int Id {get;set;}

public virtual ICollection<Product> Products { get; set; }

}

Controller:

public async Task<Order> GetById(int id)

{

Order order = await webApi.GetById(id); // webApi is a private service who calls a json converter to return a strongly typed list with derived class

return order ;

}

At this point, the object order have a Products property which is a collection of TypeA, TypeB and Product

Views:

@model Order

<div>

@(Html.Kendo().Grid<Product>(Model.Products).Name("grid")

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

.Columns(columns =>

{

columns.Bound(p => p.Label);

columns.Command(command => { command.Edit(); });

})

)

</div>

I also create templates in Views\Shared\EditorTemplates

@model Product

<div>

<h1>Product</h1>

</div>

-------------------------

@model TypeA

<div>

<h1>TypeA</h1>

</div>

-------------------------

@model TypeB

<div>

<h1>TypeB</h1>

</div>

Only the Product template pops up. I guess it's because of Grid<Product> declaration.

How can I strongly typed each row and/or have different editor template? I don't want to show PropA and PropB in my grid but I want to allow to edit them in the popup.

Thanks

Grid
