can someone help please
my platform is asp.net mvc 5 using razor pages in vs 2019 using telerik latest controls.
in my patient page I have a kendo listivew inside of a kendo TileLayout.
datasource is a list of patient name populating the listivew 
listView generate the listing of items just fine.
however, when I select on the listivew i can not get the current selected item number, 

which will generate an action
no index number, no way to find where to get the selected item.

Hi guys! I really need your help!

It is necessary to make a dynamic grid with the ability to edit cells. The grid layout appears. Column names are visible. Data is not loaded into the grid. There is an error in the browser console:"Uncaught SyntaxError: unexpected token: numeric literal" kendo.all.js:63353:40. I can’t cope with this error ...

View:

Controller:

In debug mode, the Read method does not enter ...

kendo ver. 2018.1.221.545

Please tell me what to do. 2 days I can not solve this problem

Hi Team,

I am using the Kendo Grid ASP.NET MVC. Please find the column code below. I want to do few things.

1) Edit button is position in the last column for each row having its own. Once the Edit button is being clicked, I want Edit button to be replaced with "Update and Cancel" button.

2) After clicking the edit button, the First column of the whatever row's" Edit" button being clicked will be able to editable by the user. User can type what they wanted to.

3) Once the user clicks on the "Update" button, the first column should be updated (what a user has changed) and become noneditable, and Edit button will replace the "Update and Cancel" button. If user clicks the Cancel button, then the first column would not be updated and Edit button will replace the "Update and Cancel" button. 

4) Grid rows (all data) should remain same as they were before. Refresh function would wipe out the previous data which I do not want it to happen. I want to update a specific row's first column when a user clicks the Edit button of that row. After editing and clicking the update button, the rest of the rows must remain same as they were before.

columns.Bound(p => p.ClickStatus)
        .Title("Action")
        .ClientTemplate("<button type='k-button' class='btn btn-link' id='editComment'>Edit</button>")
        .Groupable(true)
        .Width(120)
        .Locked(false)
        .HtmlAttributes(new { style = "text-align: center;" });

Please guys let me know if you know ways to do it. I have been researching this but not able to succeed. Please get back to me as quickly as possible since I am working on the project. 

Best,

I am using Telerik MVC. Is there a way to have my own look when using grouping in a dropdownlist.

I would like to have different look in the grouping dropdownlist to sowh the group value on the right for each row in the selectbox. 

Is it a way to do it?

the attached file Current.png is what I have now. the HopeToHave.png is what I was asked to do. 

It seems I can not find any document on how to do it.

The code I have is

 @(Html.Kendo().DropDownListFor(m => m.CompetencyName)
                 DataValueField("CompetencyName")
                .DataTextField("CompetencyName")
                .OptionLabel("Select...")
                .DataSource(source =>  source
                    .Custom()
                    .Group(g => g.Add("CompetencyType", typeof(string)))
                    .Transport(transport => transport
                      .Read(read => read.Action("GetAllCompetencies", "Method", new { posTitle = ViewData["Title"] }).Type(HttpVerbs.Post))
                     )
                )
    )

Thanks.

I'm trying to use this basic TabStrip example:

TabStrip Basic Usage

I can see that the first tab for "Paris" is automatically activated by specifying `.Selected(true)`.

I have done similar in my code, and my first tab is automatically activated.

But, nothing happens whenever I select different tabs.

I click Tab 2 and Tab 1 is still showing.

What am I missing?

Hi everyone,

after troubles with Telerik, I tried to re-install the ASP.NET MVC module I have a licence for, the install went well but now I cant create a Telerik app nor upgrade an MVC app. I have also de-installed VS2019 and reinstalled, no more luck.

I get the following error:

An error occurred while running the wizard.

Error executing custom action Telerik.VSX.Actions.UpdateReferencesDataAction: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\username\AppData\Local\Temp\Telerik\ShadowCopy\Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml, Version=2020.2.615.40, Culture=neutral, PublicKeyToken="**the token**"\Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.dll'.

I have not been able to find a solution at that time, have you any thought

thanks
