Format not applying to column

I have the following code:

.Columns(columns => {

columns.Bound(c => c.CreatedDateTime).Width(180).Format("{0: dd MMM yyyy HH.mm}").Title("Date");

columns.Bound(c => c.Action.ActionDateTime).Format("{0: dd MMM yyyy HH.mm}").Width(280).Title("Action Date");

})

Both columns show the date and the JSON seems to have both dates correctly passed through.

However the 1st one displays the date correctly and the second one does not.

1st DateTime: 01 May 2018 08.45

2nd DateTime: 2018-06-01T13:01:05

Further details:

The data is obtained from two joined tables using EF Core.

I had to add the Json option Referenceloophandling.ignore to get the data to pass through, though I doubt this has anything to do with the problem as the Telerik Grid obviously has the correct data.

Can someone please help me format this date correctly.

Thanks,

Ricky

Unobtrusive Validation Fires Multiple Times

I am trying to use unobtrusive validation for an ajax form inside a window. However if the window is opened multiple times then closed the validation fires multiple times. If I move the script to the main page then the validation does not fire at all.

Where should I place the validation script and how do I get it to fire only once?

@model MyProject.Models.Input

@{

Layout = null;

}

<script src="~/lib/jquery-validation/dist/jquery.validate.js"></script>

<script src="~/lib/jquery-validation-unobtrusive/dist/jquery.validate.unobtrusive.js"></script>

<script src="~/lib/jquery.unobtrusive-ajax/dist/jquery.unobtrusive-ajax.js"></script>

@*<form asp-controller="Home" asp-action="Edit"

data-ajax-begin="onBegin" data-ajax-complete="onComplete"

data-ajax-failure="onFailed" data-ajax-success="onSuccess"

data-ajax="true" data-ajax-method="POST">*@

<form asp-controller="Input" asp-action="Edit"

data-ajax-complete="onComplete"

data-ajax-failure="onFailed" data-ajax-success="onSuccess"

data-ajax="true" data-ajax-method="POST">

<input type="hidden" asp-for="InputID" />

<input type="hidden" asp-for="TemplateID" />

<label asp-for="Input" class=""></label>

<input asp-for="Input" autocomplete="off" class="k-textbox" />

<br />

<label asp-for="Description" class=""></label>

<input asp-for="Description" autocomplete="off" data-val="true" class="k-textbox" />

<span asp-validation-for="Description" class="text-danger"></span>

<br />

<label asp-for="DisplayOrder" class=""></label>

<kendo-numerictextbox for="DisplayOrder" format="0" />

<br />

<label asp-for="Format" class=""></label>

<input asp-for="Format" autocomplete="off" class="k-textbox" />

<br />

<input type="submit" value="Save" class="btn btn-primary" />

</form>

preventDefault() in beforeEdit inserts a new row on Create

Hello,

we implemented an onBeforeEdit listener for our popup-editing-grid as follow:

this.beforeEditHandler = function (e) {
var isDirty = dataSourceIsDirty();
if (isDirty) {

...
e.preventDefault();
}
}

When dirty grid-items exist, the edit-popup should not appear. This works fine when trying to edit a row, the popup is not being shown. However, when we try to create a new dataItem, the popup does not appear also, but a new empty row is being added to the grid (see attachment).

Any idea of how to prevent the grid to insert an empty row?

Thanks.

ListBox with checkboxes in a form

I have a small list of items that i need to present on a form. The user can select multiple items with the help of checkboxes. And after the user is done he needs to save the form.

I have seen a similar example on telerik products but for ajax

https://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/checkboxes/defaultcs.aspx

Is there a way to implement the same functionality in Asp.Net Core?

Styling not working for Grid

I'm porting an MVC application that uses Kendo UI to .NET Core. The existing application has considerable styling created by another team and the ported application needs to look like the old one. The new application is not picking up the old styles (I've double checked the css files and I'm sure they're all in the right location). When I look at the source on the old code, I see:

Wrapping the kendoGrid object. When I look at the source for the new code, I see:

Around the grid. Is there a difference between the MVC and .NET Core products in the way the default styles are specified? Is there a way to explicitly state what styles are used? Any idea what I might be missing between the old and new versions?

Customize Scheduler

Hi,

I have to create a room reservation calendar,

I see this sample https://demos.telerik.com/aspnet-core/scheduler/timeline and have some questions :

1) Is it possible set ".Resources(resource => ..." server side ?

2) I need only MONTH view, so is possible don't have the HOURS row ?

3) When I drag an item from cell to enother or resize an item, is there a validation system ? (if can't be done, the operation must be canceled)

4) Scheduler can be exported (pdf/excel) like grid ?

Thank you

Any way to change Theme visually in VS2017?

Hi Team;

I have installed Kendo UI fpr ASP Core into my project. Is there anyway that I can change theme "Visually" like a drop down list of themes Kendo UI offers that would automatically changes inside _Layout or anywhere else related?
Or at least a doc guideline of exact changes to be made manually to ensure we can change to the list of Default themes or Bootstrap themes based on the attached pic?

Thanks

..Ben

Kendo UI R2 2018, what version of Bootstrap?

Hello Team;

For my new project, I'll be using MSFT ASP.Net Core 2.1. Unfortunately MSFT did not upgrade the bootstrap to V4.x and left the V3.x in ASP Core installation.

My first question is, in this latest version of Kendo UI R2 2018 (May), which version of Bootsrap does Kendo UI use?
If it uses V4.x, do you suggest that we upgrade our MVC project to Bootstrap V4.x to stay compatible with Kendo?

Or any other guidelines?

Thank you in advance!
..Ben
