Hello,

I'm encountering an issue with the autocomplete functionality in Kendo UI Grid. While the data selected through autocomplete is correctly added to hidden fields, it does not appear in the Grid.

Specifically, after using the autocomplete functionality, I checked whether the correct data was added to the respective hidden fields and found that the values I expected were indeed present in those fields. However, I noticed that these values were not visible in the Grid. This implies that the data selected by users is not being properly reflected within the Grid.

In summary, I am unable to display the data received through the autocomplete functionality within the Grid. I would appreciate any suggestions to resolve this issue.

The code structure related to the problem I mentioned above is as follows.

@(Html.Kendo().Grid(Model.Lines)
    .Name("OrderLines")
    .ToolBar(tools => tools.Create().Text("Add new product"))
    .Editable(editable => editable.Mode(GridEditMode.InCell).CreateAt(GridInsertRowPosition.Bottom))
    .Events(events => events
    .Change("onChange"))
    .Columns(columns =>
    {
        columns.Bound(p => p.Title)
        .ClientTemplate("#= Title #" +
        "<input type='hidden' name='Lines[#= index(data)#].Title' value='#= Title #' />")
        .EditorTemplateName("ProductTitleAutoComplete");

        columns.Bound(p => p.Title).Hidden().ClientTemplate("#= Title #" +
        "<input type='hidden' name='Lines[#= index(data)#].Title' value='#= Title #' />"
        );

        columns.Bound(p => p.Description).ClientTemplate("#= Description #" +
        "<input type='hidden' name='Lines[#= index(data)#].Description' value='#= Description #' />"
        );

        columns.Bound(p => p.Quantity).ClientTemplate("#= Quantity #" +
        "<input type='hidden' name='Lines[#= index(data)#].Quantity' value='#= Quantity #' />"
        );

        columns.Bound(p => p.UnitPrice).ClientTemplate("#= UnitPrice #" +
        "<input type='hidden' name='Lines[#= index(data)#].UnitPrice' value='#= UnitPrice #' />"
        );

        columns.Bound(p => p.TaxRate).ClientTemplate("#= TaxRate #" +
        "<input type='hidden' name='Lines[#= index(data)#].TaxRate' value='#= TaxRate #' />"
        );

        columns.Bound(p => p.DiscountRate).ClientTemplate("#= DiscountRate #" +
        "<input type='hidden' name='Lines[#= index(data)#].DiscountRate' value='#= DiscountRate #' />"
        );

        columns.Bound(p => p.PurchaseOrderId).Hidden().ClientTemplate("#= PurchaseOrderId #" +
        "<input type='hidden' name='Lines[#= index(data)#].PurchaseOrderId' value='#= PurchaseOrderId #' />"
        );

        columns.Bound(p => p.ProductId).Hidden().ClientTemplate("#= ProductId #" +
        "<input type='hidden' name='Lines[#= index(data)#].ProductId' value='#= ProductId #' />"
        );

        columns.Bound(p => p.Id).Hidden().ClientTemplate("#= Id #" +
        "<input type='hidden' name='Lines[#= index(data)#].Id' value='#= Id #' />"
        );

        columns.Bound(p => p.MeasureWeightId).ClientTemplate("#= MeasureWeightId #" +
        "<input type='hidden' name='Lines[#= index(data)#].MeasureWeightId' value='#= MeasureWeightId #' />"
        );

        columns.Command(command => command.Destroy()).Width(100);
    })
    .DataSource(dataSource => dataSource.Ajax()
    .Model(model =>
    {
        model.Id(p => p.ProductId);
        model.Field(p => p.ProductId).Editable(false);
    })
    .ServerOperation(false)
    ))

function onChange_ProductAutoComplete(e) {
    var dataItem = e.sender.dataItem(0);

    var grid = $("#OrderLines").data("kendoGrid");

    if (dataItem) {
        var el = $(e.sender.element[0]);
        const parent = el.closest("td");
        const inputs = parent.siblings().find('input');

        $(inputs).each(function () {
            var name = $(this).attr('name');
            if (name.endsWith("Description")) {
                $(this).val(dataItem.Notes);
            } else if (name.endsWith("ProductId")) {
                $(this).val(dataItem.Id);
            }
            else if (name.endsWith("Title")) {
                $(this).attr({ value: dataItem.Title });
                $(this).val(dataItem.Title);
            }
            else if (name.endsWith("MeasureWeightId")) {
                $(this).val(dataItem.MeasureWeightId);
            }
        });
    }
}

function onReadDataOnGrid_ProductAutoComplete(e) {
    let data = {
        title: $('#Title_ProductAutoComplete').val()
    };

    return data;
}

Thank you in advance for your support.

I had a request to change the filtering of a certain column from "Starts With" to use a multi-select checkbox type filter to facilitate selecting 5-10 random items.  Then of course some other users prefer the "Starts With" type of filtering.  My solution is to have dual columns for that particular field, one with each filter type.  

Since my grids save user preferences in local storage between sessions, the users can hide whichever column has the filtering they don't prefer and just use the other one.  When they reload the page, their choice of column persists and their filtering is how they like it.

Is it possible to extend the Telerik MVC Grid toolbar to include custom commands? I'm looking to add my own functionality to the toolbar, and I'm wondering if there's a way to create a method within the toolbar command factory to generate buttons with specific functionality that I want to apply across all grids in my application.

For example, I have these three methods I have added using the toolbar template.


instead of using the template every time I would like to add custom command like save or excel.

I'm trying to export a grid to Excel, and I have followed the Telerik example:

https://demos.telerik.com/aspnet-mvc/grid/excel-export?autoRun=true&theme=default-main

But what I cannot manage to do is to prevent a call to excel_export_read when clicking the Export to Excel button. In Chrome Devtools I can see that also the official Telerik example calls this method a second time when clicking, but I was under the impression that the component would try to create the excel file client side. Is this not possible?

Here is my code:

 

@(Html.Kendo().Grid<CampaignSimulationResult>()
    .Name("SimulateResult")
    .ToolBar(tools => tools.Excel())
    .DefaultSettings()
    .Columns(column =>
        {
            column.Bound(m => m.Region).HeaderHtmlAttributes(new { style = "text-align:center" })
                .HtmlAttributes(new { style = "text-align: center" });
            column.Bound(m => m.ParameterID).Format("{0:##,#}").HtmlAttributes(new { style = "text-align: right" }).HeaderHtmlAttributes(new { style = "text-align:center" });
            column.Bound(m => m.Parameter).HtmlAttributes(new { style = "white-space: nowrap;" }).HeaderHtmlAttributes(new { style = "text-align:center" });
        }
    ).Excel(excel => excel
        .FileName("Kendo UI Grid Export.xlsx")
        .Filterable(true)
    )
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("ExcelExportRead", "Campaign", new RouteValueDictionary { { "area", "Admin" } }))
    )
)

I've been working with the Kendo DatePicker UI component and I really like the masking and validation it provides if a user wants to manually enter a date when DateInput() is applied. However, it also adds segmentation which means a user either needs to click or use arrow keys to move on to edit other parts of the date like month, day or year. If I remove DateInput() there is no more segmentation, but also no validation or masking. Is there a way to keep validation and masking in the date input field without the segmentation and keep the date picker functionality? My other option is to remove .DateInput() along with the messages and manually apply validation and masking, but if there is a solution within the component itself, that would be ideal. Below is what we currently have.

                                                       @(Html.Kendo().DatePicker()
.Format(Model.DateMask)
.Name("DateStart")
.DateInput()
.Messages(m => m.DateInput(d => d.Day("__")))
.Messages(m => m.DateInput(d => d.Month("__")))
.Messages(m => m.DateInput(d => d.Year("____")))
.Culture(UICulture)
.Footer(false)
                          )

From https://www.telerik.com/download/custom-download# I tried to download the latest version 2024.1.130 kendo.custom.min.js file in order to upgrade the kendo plugin  from Kendo UI 2022.1.412 version to the latest. 
I use Asp.Net MVC and I have a custom bundler where I reference all the js files like this

 bundles.Add(new ScriptBundle("~/bundle/kendo").Include( "~/Scripts/kendo/kendo.custom.min.js"));   

Then in Razor Layout page I register bundles like this

@Scripts.Render("~/bundle/kendo")

but whenever I run the application I always get a NullReferenceException at the line that registers the bundle with the message "No object reference is set to an object instance."

Whenever I downgrade the kendo version or return to the previous one the application runs properly.

Any ideas why is this happening? Would you please help me solve this issue? 

Thanx in Advance.

Can we change the starting day of the week from Sunday to Monday? i.e. MO, TU, WE, TH, FR, SA, SU

Or Sunday to Saturday? i.e. SA, SU, MO, TU, WE, TH, FR

Instead of the current: SU, MO, TU, WE, TH, FR, SA

Is it possible to make it so if a user clicks a day it selects the whole week, like clicking the week number does? Then is it also possible to capture multiple selected weeks (not necessarily concurrent weeks or in the same month), even if all the dates in those selected weeks are the output that would be fine

My page has a combo box. As the user selects an ID from the dropdown list, the page populates with information corresponding to the entry. It is an AJAX bound combo box. I am trying to make the combo box get auto populated with an ID from my query string on initialization. 

I've tried setting the .Value field of the combo box. This works to automatically select the correct ID and populate the rest of the page, but only when the ID exists in the data source. My AJAX call returns data based on the partial/full ID passed in, and a list of a few most recent ID's if no input ID is specified. 

I believe this will work if the ID exists in the data source prior to setting the value field of the combo box. But for that to happen, the combo box must use the ID from the url to fetch the data source, similar to what happens when a user manually types that ID into the combo box. However, I am struggling to figure out how to pass in a specific ID when the combo box is responsible for making the AJAX call. 

I would appreciate any advice or other suggestions to getting the intended behavior.
