Hello Kendo Experts,

I'm currently working on integrating a Kendo JQuery Grid with an ASP.NET Core server-side setup that utilizes Fluent Validation for data validation. When submitting data via the grid, the server responds with a structured error message in case of validation failures, following this format:

My goal is to handle these validation errors and present them to the user in a user-friendly manner within the Kendo Grid interface. This involves processing the error messages received from the server and displaying them near the corresponding input fields for easy identification and correction by the user.

Could you kindly provide guidance or suggestions on how to achieve this? Any insights or examples on how to format and display these error messages effectively within the Kendo Grid would be greatly appreciated.

Thank you for your assistance.

I have a model DateTime property called CreatedDate and If I try to filter by date  using the filter 'Is equal to' for a single date, it will not filter the records for the given date due its time part in it filter checking. So How can I make it filter truncating the time part from the filter ?
Pol

public class EmployeeViewModel

{

public string Name{get; set;}

public DateTime  CreatedDate{get; set;}

}

In Kendo Grid
column.Bound(c=>c.CreatedDate).Title("Created Date")

I am trying to sort alphabetically string values inside the multi filter combobox in Kendo Grid to filter. Now it shows randomly there is no any order in mvc. Here is the code

columns.Bound(c => c.EmpName).Title("Employee Name")
.Filterable(filterable => filterable
.Multi(true)

I am trying to create a multifilter from enum data type column using the ItemTemplate. But ItemTemplate Javascript function is not being called and data is not being shown in combobox. Please can you give me a help. Here is the code

Enum Records

public enum EmpTypes
{
    [Display(Name = "Service")]
    Service = 0,
    [Display(Name = "Sales")]
    Sales = 1,
    [Display(Name = "Purchase")]
    Purchase = 2,
    [Display(Name = "Office")]
    Office = 3
}

Kendo Grid

columns.Bound(c => c.EmpTypes).Title("Type")
        .Filterable(filterable => filterable
            .Multi(true)
            .UI(“”).DataSource(s=>s.Read(r=>r.Action(“GetEmpTypes”,”Report”)))
            .ItemTemplate(“typetemplate”));
<script>
 function typetemplate(e)
{
  alert('Test');
}

</script>

Public ActionResult GetEmpTypes()
{
 List<EmpType> emptypes = new List<EmpType>();
emptypes.Add(EmpType.Sales)
emptypes.Add(EmpType.Report)
return Json(emptypes,JsonRequestBehavior.AllowGet);
}

Does anyone have any idea on how to create a chart with Axis like this with the Kendu UI for JQuery?

Specifically I'm trying to recreate the Y Axis.

You use it to bind to a viewModel:

viewModel.bind("change", function( event ){
    console.log("BIND:", event.field, "=", this.get(event.field));
});

this.get(event.field)
has the data just modified.

Is there a way to get the old data, before change?

Many thanks

Given this code:

cols - API Reference - Kendo UI TextArea - Kendo UI for jQuery (telerik.com)

If I change the cols from 30 to 3 it doesn't seem to change the width of the textarea? Isn't the width of the textarea supposed to decrease?

<textarea id="description"></textarea>
<script>
    $("#description").kendoTextArea({
        rows:20,
        cols:30,
        resizable: "vertical"
    })
</script>

Is this a bug?

Thanks!

Hello,

I am currently using Kendo version 2024.1.130 with ASP.NET core Razor Pages.

In this version I am unable to get a sum aggregate to show. Nothing woks, not even a "ABC" string. The footer is visible and all columns contain a  

Relevant Code:

@(Html.Kendo().Grid<ItemViewModel>()
    .Name("grid")
    .Filterable()
    .Sortable()
    .Scrollable()
    .Columns(columns =>
    {
        //...
        columns.Bound(c => c.ExtendedPrice).Title("Extended Price").Format("{0:n0}").ClientFooterTemplate("#=sum#");
        //...
    })
    .DataSource(dataSource => dataSource
        .Ajax()
        .Aggregates(aggregates =>
        {
            aggregates.Add(p => p.ExtendedPrice).Sum();
        })
        .Read(read => read.Action("GetList", "Bom").Type(HttpVerbs.Get).Data("getParameters"))
        .Events(e => e.Error("showSimpleModelStateErrors").RequestStart("clearErrors").RequestEnd("gridDataLoaded"))
    )

Is there a way to expand disabled nodes in the treeview component? There was a solution (https://www.telerik.com/forums/expand-disabled-nodes) but with the current version of kendo-ui it does not work anymore.

It seems that the expand/collapse icon is now disabled as well and it does not fire any event. Is there another solution to make this work again?
