Am considering use of server side filtering and paging for combobox because expecting large number of dropdown values.

What would be  the recommended number of values count for which the use of server side filering/paging is recommended?  When would one start seeing performance issues with large number of dropdown values?

Thnks.

Is there a guide for creating a Asp.Net core application on Mac OS X using kendo.ui for asp.net core ?

Or just using OS Windows and IDE VisualStudio ? 

Hello,
I'm new to Telerik and I'm trying to run your Scheduler demo for Core in my Visual Studio 2017. I installed Telerik.UI.for.AspNet.Core(2019.1.115) in my VS 2016.
But when I copy the code from your demo I get an error in: @(Html.Kendo().Scheduler<Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel>()

Under Kendo.Mvc.Examples it cannot find "Models". Did the dll changed? How can I get to Kendo.Mvc.Examples.Models.Scheduler.TaskViewModel ?

I am using a DateTime column with filterable options enabled. When I apply a filter on this column, the request.Filters has a valid DateTime but it is applying an incompatible format when it calls SQL Server. Here is my code:

    public async Task<JsonResult> OnGetDataAsync([DataSourceRequest]DataSourceRequest request, CustomFilterModel customFilters)
    {
        IQueryable<DAL.Product> products = this.productService.GetByCriteria(customFilters);

        JsonSerializerSettings jsonSettings = new JsonSerializerSettings()
        {
            ContractResolver = new DefaultContractResolver()
        };

        return new JsonResult(await products.ToDataSourceResultAsync(request), jsonSettings);
    }

This is what EF generates: (abbreviated for clarity)

    SELECT ....
    WHERE [p].[DateAdded] <= '2018-10-01T00:00:00.0000000'

**Error:** System.Data.SqlClient.SqlException (0x80131904): Conversion failed when converting date and/or time from character string.

Basically, the generated SQL query does not work when I run it directly in SMMS. It only works if I convert the date to **'2018-10-01T00:00:00'**

Tech stack: .NET Core 2.2, Razor Pages, Kendo 2018.3.911, SQL 2018

I have two auto completes working on the main page of this application.  One on the header and one that appears when the user resizes the browser down to a smaller screen width/

Both use the same controller ajax action.  It seems the first time the user types in the values it take about 5 seconds to render matches.  And subsequent searches are instant.  

Is there a way to optimize that so that that first search is instant?  Please note that the dataset is large.  Over 10,000 products.  But that data is cached in .NET Core at application startup so it is not hitting the database again on each search or a web service, rather reading from the same cached list.  And that list is optimized to contain only two fields, the product name and primary key.

Is there a way to pre-read the data for the list to make it faster?

 

Thanks

Wanting to add tooltips to column headers on the grid.

Trying:

$(document).ready(function () {
    //grid header tooltip
    $('thead [data-title]').kendoTooltip({
        content: function (e) {
            return $(e.target).text();
        },
    });
})

 

Seems to work except there appears to be spurious tooltips.  Please see attached 1.png and 2.png.

These appear to be from title attributes from within child elements.  Please see 3.png and 4.png.

In the case of 3.png the title="" attribute appears to be dynamically added.

Would like to remove the empty title="" tooltip and convert the column menu tooltip due to title="Column Menu" to be of kendoTooltip as well (preferably using single initialization step).

 

 

     Hi;

I'm newbie to core and trying progress controls. I'm using razor pages and i couldn't find any sample about selecteditemchanged event usage for filling other controls from db. 

Is it possible to give a short sample? If filling can be done serverside will be more happy :) 

 

Thanks

How do you remove the "Add Task" button?  My Gantt chart is completely driven from database values, so I don't want my users to be able to add tasks to the Gantt, they only need to see schedule.

Thanks
