• Disable shared tooltips. This will not negatively affect Sparklines with only one series.
  
  $("#hum-log").kendoSparkline({

Hello. I am using a custom column editor as shown in your example : https://docs.telerik.com/kendo-ui/knowledge-base/custom-editor-autocomplete. Even in the example that you provided, if I type a value that is not in the list, on focus out the field will display "undefined" and will remain this way even if i try to select another value. Is there a fix for this situation? Thank you in advance :)

I attached a screenshot from your working example.

Hi,

we want to persist the width of resizable columns, only.

We are aware of this article (https://demos.telerik.com/aspnet-mvc/grid/persist-state) and the getOptions() and setOptions() functions, but these get/set other options like sort and page.

We only want to persist the column width. Is there a supported way of doing this?

Kind regards.

Using the code below I can successfully update a gantt task (I'm using a custom edit screen + custom update function). It fires off my transport update handler and axios does the update just fine.

  var task = ganttdataSource1.at(0);
  ganttdatasource1.update(task, { title: "New Title" });
  ganttdatasource1.sync()

  var task = ganttdataSource1.at(0);
  ganttdatasource1.update(task, { 
        title: "New Title", 
        resources: {
            taskId: 111,
            resourceId: 222,
            value: 5,
        } 
    });

  ganttdatasource1.sync()

I want to make a grid with excel exporting feature which will export all data.

However, the grid might contain a massive amount of data that makes the export process spends lots of time.

I've found this that shows confirmation before exporting.

https://docs.telerik.com/kendo-ui/knowledge-base/export-the-grid-to-excel-only-after-confirmation

However, the confirmation popup window shows after loading all data (it popup after a few time after I click the export button, so I guess it loads all the data, or the excelExport event is activated after the excel file is well prepared to be exported).

Is it possible to show the confirmation window as soon as I click the export button?

Thanks.

I'm trying to make my grid be able to export its data as a CSV file, and I saw this:

https://www.telerik.com/forums/export-to-csv-also-collapse-data

which said that currently, Kendo UI does have only build-on support for export to PDF and Excel(xlsx).

However, after surveying on the internet I find another one:

https://feedback.telerik.com/kendo-jquery-ui/1359149-export-ability-to-export-the-grid-in-csv-and-xml-formats

It says that it's a completed feature, but I only find the sample using ASP.net:

https://demos.telerik.com/aspnet-mvc/grid/server-export

Since It's a completed feature, does it involve jQuery? or is it just support using ASP.net?

If it involves jQuery, can anyone provide a sample of it?

Thanks.

Hi,

I have added Kendo dropDownList as cell editor to Kendo Gantt. 

After some time, some users reported issue where doubleclick on cell randomly just opens and closes dropdown on its own. 

We did quite a lot of debugging until we were able to reproduce issue. 

It turns out that in some cases (not clear under which conditions) when doubleclick is either too fast or performed on laptop touchpad, it happens almost in 30% of cases.

(We are using kendo UI 2020 R2 version, but issue is reproducible even in latest version).

Issue was reproduced by developer on Dell Latitude 5580 (using touchpad doubleclick), while users reported on other systems.

Here you can find the dojo where issue is reproducible.

https://dojo.telerik.com/aHuDaYup/4

Also, we recorded video on the same dojo, where behavior is demonstrated. 

First 4 clicks are mouse, and next ones are with touchpad. (users were having issues even with mouse)

If there are any things we can do to help, please let me know.

Thank you and best regards.

I'm having a problem getting an MVC ListView to initially load via the model and then page using Ajax. I've configured a grid to do this without issues but the ListView datasource doesn't seem to support Ajax, although the documentation suggests it does?

https://docs.telerik.com/aspnet-mvc/html-helpers/data-management/listview/binding

I initiate the list with 10 records and then specify the total amount of records in the datasource. I then expect to see 10 records on the first page and to have the ability to click on the other pages. When I click on a page an Ajax call should be made to retrieve the relevant records. However all I see is the 10 records from the model and no paging. 

Here is my ListView:

   @(Html.Kendo().ListView<Feed>(Model)
        .Name("FeedList")
        .TagName("ul")     
        //.BindTo(Model)
        .ClientTemplateId("feed-detail-list-template")
        .DataSource(
            source => source                     
                //.Ajax() I get an error that there is no definition for Ajax if I uncomment this
                .ServerOperation(false)
                .Model(model => model.Id(p => p))
                .Read(
                    read =>
                    {
                        read.Action(action, controller, new { id = parentId });
                    }
                )                
                .PageSize(10)
                .Total(totalRecords) // appears to be ignore
                .Events(events => events
                    .Error("onDataSourceError")
                )
        )
        .Pageable()
    )
