Hi, I am new to kendo grid and over all telerik, I am having issues populating the data.  

please check the code below. This is the simplest form.  

//cshtml view

@using Kendo.Mvc
@using Kendo.Mvc.UI
@model IEnumerable<Database.Station>
@{
    ViewBag.Title = "Records";
//    foreach(var v in Model)
//    {
//      var i=  v.Componenet;
//    }
}

@ViewBag.heading
<hr />


<hr />



@if (Model.Any())
{
    <div>

          @(Html.Kendo().Grid(Model) 
    .Name("grid")
    .Columns(columns => {
        columns.Bound(p =>p.ATA).Width(100);
        columns.Bound(p => p.Componenet).Width(100);
        columns.Bound(p => p.Description).Width(140);
        columns.Bound(p => p.DiskNumber);
        columns.Bound(p => p.SoftwareNumber).Width(150);
    })

    .HtmlAttributes(new { style = "height:430px;" })
    .DataSource(dataSource => dataSource
        .Ajax()

        .Read(read => read.Action("Main", "Station"))
     )
)
    </div>
    }

//controller

  public IActionResult Main()
        {
            var stationList = new List<Station>();
            var station = new Station
            {
                ATA = "22",
                SoftwareNumber = "check",
                DiskNumber = "1234",
                Componenet = "AC",
                Description = "Description"
            };
            stationList.Add(station);

            var station2 = new Station
            {
                ATA = "29",
                SoftwareNumber = "check2",
                DiskNumber = "1235",
                Componenet = "Bike",
                Description = "Description"
            };
            stationList.Add(station2);
            return Json(stationList);

        }
    }

I also noticed following the instruction. it does not tell me to include any css or javascript or any javascript code in script section. so nothing of that natrure is included.  Below is the outcome of the nuget.  I have no css or other js file from kendo. 

And this is what i get

Hi,

I would like to know if there's a way of displaying files that are already uploaded in the upload widget.
To make my inquiry clear, I want the upload widget to act as a table of the upload files it has already uploaded. The current behavior only shows the files that are added in the document at the moment  of uploading. Once you navigate out of the page and back the upload files array gets emptied.

Thanks in advance for any response!

Our customers using the spreadsheet copy/paste values in the Spreadsheet (ASP. NET CORE)

Sometimes pasted decimal separator is ".", sometimes is the ",".

Is there a way to search and replace the pasted values from "," to ".", or, if not, to search and replace in Spreadsheet ?

Hello,

I am working on an application that the client has just added additional filter criteria beyond what grid filter provides.

I believe I might be able to do this using the example here Create Filter Widgets with Multiple Filter Criteria | Kendo UI Grid for jQuery | Kendo UI for jQuery (telerik.com) - maybe. I'm using ASP.Net Core 5 Razor pages so sometimes examples don't always work.

All of the fields (except for a couple that are date fields) are char or text type columns in the database.  The client wants to be able to use functions like "greater than", "in",  and "Is one of".  (I know greater than is not going to give them what they think) but the In condition or the Is One of condition they say are needed.

The filter now for 2 items is not enough.

For example, they need to filter for several POs at once - as you might do with a sql query SELECT * FROM tableaname WHERE fieldname in ('po1', 'po1', 'po3', 'po4') as an example.  none of the data is sequential so the need for "IN" or "IS ONE OF" filtering conditions.

Is this possible?

How would it be coded and handled on the backend?

Are the available filters documented somewhere here on the site?

Can we use wild cards in the filter value?  As when the search condition may vary inside the string and not with the start or end with characters?

thanks!

Hello all,

Could someone point me to an example or suggest the best approach for this? The application is asp.net core 5 using Razor.

I am using GridColumnSettings in my grid because there is one SQL table to populate many different pages & we change elements based on the context of use.

On one page, we've added a custom function to the filtering for one column so that we can provide a SQL "IN" condition.  This is working great. However for that one column, can someone suggest how to provide a custom filter menu so that we restrict what options are provided. (Users are going to be confused if they have options on the filter menu that do not work as they expected...)

I've tried a few examples found from searching this site but none seem to work.  Either I got it wrong (for possible) or  because of the columns.LoadSettings<Model.columns> from the server side, it doesn't execute any client side code on the .cshtml page.

I've included the relevant code below.

Any suggestions or examples will be greatly appreciated.  Thank you.

This is the grid on the .cshtml page.

<div id="griddiv">
    @(Html.Kendo().Grid<HPK_DATA>(Model.testdata)    
    .Name("grid")
    .Columns(columns => {
       columns.LoadSettings(Model.columns);
    })
    .Events(ev=>{
        ev.Filter("onFilter");
        //ev.FilterMenuInit("filterMenuInit");
    })
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Read(read => read.Url(Url.Action()+"?handler=Read").Data("forgeryToken"))
     )
)
</div>

This is a portion of the gridcolumnsetting code for brevity.  The column that needs a custom filter menu is the SERIAL_NO.

What is required to filter a grid on a DateTime without specifying the time?
i.e.: I want to see all records for a date.  All for 2022-05-18 regardless of the time.

Or do you have to specify the date using identifying greater than and less than?  i.e.: > 2022-05-17 and < 2022-05-19

Is there a way to hide or prevent a tooltip from showing if there is no content?

What I'm trying to do is prepopulate fields in a View with Tooltips (so I don't have to code them in later).

Tool tips are then obtained in the Controller from a ToolTip File which would contain Content and Width.  If there is no content for the field in the ToolTip file, I don't want the tool tip to show.  Right now, if Content is NUL and Width is 0 (zero) then you get a small black box as shown in the attached picture

Hi there

I have a grid with draggable functionality but if I enable the default sort the drag & drop won't work any more.

I'm setting the default sort in jquery:

grid.dataSource.sort({ field: "Id", dir: "asc" });

I've tried to do it in C# code but got the same results.

Can anyone help me with it ?

Thanks

After updating a working .NET 5 project to .NET 6 and upgrading Nuget package Telerik.UI.for.AspNet.Core from 2021.2.511 to 2022.2.510, I am now receiving an error using IntegerTextBoxFor on an object property model. The error is

FileNotFoundException: Could not load file or assembly 'Microsoft.DotNet.InternalAbstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

Below are screen shots of:

1.  The exception
2.  The Nuget packages 1.) From the .NET 5 working solution and 2.) from the .NET 6 solution that crashes.
3. The line of code that causes the exception. Note that if I bind to a simple property instead of a complex object property, the error does not happen.

Nuget Package Telerik.UI.for.AspNet.Core

The Nuget package on the left is referencing version 2021.2.511. As you can see, that version includes a reference to the file that is causing the error, which is Microsoft.DotNet.InternalAbstractions. The package on the right is referencing the latest version 2022.2.510 and that package does not include the file that is causing the error.

@(Html.Kendo().IntegerTextBoxFor(x => x.Product.Odometer)
    .Min(0)
    .Culture(Localizer.CultureCode)
 )

If this file is still a dependency of that particular Telerik package, why is it missing? And please advise on how to fix this.

Thank You,
