In our UI for ASP.NET Core R3 2020 (2020.3.915) release, the Column menu message of unsticking a column is "null".

This bug will be resolved in our next official release.

In the meantime, as a workaround, manually set the Unstick Column menu message:

.ColumnMenu(c => c.Messages(m => m.Unstick("Unstick Column")))

I have a grid and I want to sum the number of true values in a boolean column. Is there a way to create a custom aggregate function to achieve this?

Hello,

Is it possible to have server filtering in Razor Net Core 3.1? We used the demo as our base and referred to the documentation for server filtering (https://docs.telerik.com/aspnet-core/html-helpers/scheduling/scheduler/server-filtering). However we cannot pass Data("getAdditionalData") and the Data("forgeryToken") at the same time. Does anyone know how we can go about doing this so we can filter the results on the database side? Without the forgeryToken in Data, the app does not trigger the Read method (OnPostMeetings_Read)

Any insight is appreciated.

Thank you!

I have a list of Countries in my Grid, a country has a Code, that is unique. The Grid is in EditCell mode. 

I need to perform a check, if newly inserted Country Code is Unique. 

So, on the controller I have

        [AcceptVerbs("GET", "POST")]
        public IActionResult KeyExist(string key)
        {
            if (_countryService.CodeExists(key))
            {
                return Json($"The Code '{key}' is already used, please try another one!");
            }

            return Json(true);
        }
how should I bind the KeyExist method to the grid's validation?

I have created a ViewComponet that contains a Kendo textbox.

		public async Task<IViewComponentResult> InvokeAsync(ModelExpression aspFor)
		{
			return View("MyView", new MyModel(){AspFor = aspFor ... });
		}

My AspFor when it gets to the view is an instance of a ModelExpression, but the Kendo controls are expecting a string for the "Expression()" method.

How do I bind this Kendo control to the instance of the ModelExpression?

The TextBoxFor isn't happy and attempting to convert the ModelExpression instance back to its string doesn't result in HTML that contains all of the proper attributes on it.

Thanks

The controller is definitely being hit and it is returning data in the format I was expecting. I have javascript in the "RequestEnd" and I am seeing data there. There are no errors or warnings (that pertain to the listview) in the browser's developer console. The pager shows up but says there are zero records. I have been tossing code at this for waaaaay too long.

Any suggestions? Please.....

 

Controller:

[HttpPost] [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)] public async Task<IActionResult> UserProfiles_Search([DataSourceRequest] DataSourceRequest request) { Logger.LogInformation("In UserProfiles_Search");

// dummy data var data = new List < UserProfile >(){ new UserProfile() { Title = "Mrs", FirstName = "Joanne", LastName = "Welch", EmailAddress = "joanne.welch@example.com", Id = Guid.Parse("3c7b201d-9744-4807-bd53-192251fb6e60") }, new UserProfile() { Title = "Miss", FirstName = "Florence", LastName = "Lawrence", EmailAddress = "florence.lawrence@example.com", Id = Guid.Parse("6691697e-faa5-41ec-89b0-b6a040be8d2d") }, new UserProfile() { Title = "Mrs", FirstName = "Stella", LastName = "Laurent", EmailAddress = "stella.laurent@example.com", Id = Guid.Parse("87cf6fef-0d9e-4fea-bbca-b48d9f478c61") }, new UserProfile() { Title = "Ms", FirstName = "Sharida", LastName = "Broeren", EmailAddress = "sharida.broeren@example.com", Id = Guid.Parse("d58fcf47-88ac-4753-8d08-3cbf0318c13d") }, new UserProfile() { Title = "Mr", FirstName = "William", LastName = "Liu", EmailAddress = "william.liu@example.com", Id = Guid.Parse("688fff10-e522-4267-a061-5553c627689e") }, new UserProfile() { Title = "Ms", FirstName = "Brielle", LastName = "Clark", EmailAddress = "brielle.clark@example.com", Id = Guid.Parse("00fa0fa0-494f-44e5-9bb2-5fbcea156eb7") }, new UserProfile() { Title = "Miss", FirstName = "تارا", LastName = "زارعی", EmailAddress = "tr.zraay@example.com", Id = Guid.Parse("3a7ddd17-33a3-489a-91b9-48055eefb55e") }, new UserProfile() { Title = "Mr", FirstName = "Necati", LastName = "Karadaş", EmailAddress = "necati.karadas@example.com", Id = Guid.Parse("33c54e50-7297-4af0-914c-484f182d0e52") }, new UserProfile() { Title = "Ms", FirstName = "Elizabeth", LastName = "Craig", EmailAddress = "elizabeth.craig@example.com", Id = Guid.Parse("6841bcec-6662-473e-9b1a-d5f533ab01d8") }, new UserProfile() { Title = "Mr", FirstName = "Karl", LastName = "Gordon", EmailAddress = "karl.gordon@example.com", Id = Guid.Parse("43ec6d51-5b3e-4e6d-ae78-4394234950b4") }, new UserProfile() { Title = "Mrs", FirstName = "Gretel", LastName = "Bender", EmailAddress = "gretel.bender@example.com", Id = Guid.Parse("54dab09c-1d6f-4544-aa23-0fb74f3f12c9") }, new UserProfile() { Title = "Mrs", FirstName = "Francelina", LastName = "Nunes", EmailAddress = "francelina.nunes@example.com", Id = Guid.Parse("3c62214b-c797-4cdb-9623-cbc51ec8a86f") }, new UserProfile() { Title = "Monsieur", FirstName = "Oskar", LastName = "Berger", EmailAddress = "oskar.berger@example.com", Id = Guid.Parse("4687147c-8630-4018-afb8-52cdb0e1937a") }, new UserProfile() { Title = "Miss", FirstName = "Emilie", LastName = "Carpentier", EmailAddress = "emilie.carpentier@example.com", Id = Guid.Parse("8b11fb43-93da-470c-bc1a-eddce87a3ecc") }, new UserProfile() { Title = "Mrs", FirstName = "Florence", LastName = "King", EmailAddress = "florence.king@example.com", Id = Guid.Parse("f203e0b7-ebe3-4a72-b82e-c910b9daa3fd") } }; var resultData = await data.ToDataSourceResultAsync(request); return Json(resultData); }
