Scheduler Editor Model Valid Is False closes popup rather than keeping it open

Hey, On my schedule editor pop up I'd like to enforce the server side model validation, however currently, if ModelState.IsValid == false, rather than keeping the editor open and showing an error it closes.

Is there a way for the editor to stay open if the model validation returns false?

 

        public async Task<JsonResult> SchedulerCreate([DataSourceRequest] DataSourceRequest request, TaskViewModel task)
        {

            if (ModelState.IsValid)
            {
                await Persist(task);

            }
            return Json(new[] { task }.ToDataSourceResult(request, ModelState));
        }

Unable to display list of object in Kendo Grid Column

Hi there,

I have a hard time getting my grid displaying the data I want to see.

 

Main Object

public class CustomerViewModel
{
    [Key]
    public string Vin { get; set; }
    public List<Campaign> TechnicalCampaigns { get; set; } = new();
    public string? CustomerNumber { get; set; }
    public string? CustomerName { get; set; }
}


Campaign Model


public class Campaign
{
    public string Vin { get; set; }
    public string CampaignId { get; set; }
}


Grid


Html.Kendo().Grid<CustomerViewModel>()
                .Name("grid")
                .Columns(columns =>
                {
                    columns.Bound(p => p.Vin).Filterable(ftb => ftb.Multi(true).Search(true).CheckAll(true)).Width(100).Title("Vin").HtmlAttributes(new { style = "text-align: center" }).Locked(true);
                    columns.Command(command => { command.Edit(); }).Width(150).HtmlAttributes(new { style = "text-align: center" }).Locked(true);
                    columns.Bound(p => p.CustomerNumber).Filterable(ftb => ftb.Cell(y => y.Template("datePicker"))).Width(100).Title("Kundennummer").HtmlAttributes(new { style = "text-align: center" });
                    columns.Bound(p => p.CustomerName).Filterable(ftb => ftb.Multi(true).Search(true).CheckAll(true)).Width(100).Title("Kunde").HtmlAttributes(new { style = "text-align: center" });

                    columns.Bound(p => p.TechnicalCampaigns).Width(200).Title("Offene TA's").HtmlAttributes(new { style = "text-align: center" }).ClientTemplate("#=generateTemplate(TechnicalCampaigns)#");

                .ColumnResizeHandleWidth(20)
                .ColumnMenu()
                .Sortable()
                .Scrollable(s => s.Height("auto"))
                .Filterable()
                .Reorderable(reorder => reorder.Columns(true))
                .Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("CustomPopupTA"))                
                .DataSource(dataSource => dataSource
                    .SignalR()
                    .AutoSync(false)
                    .PageSize(10)
                    .Sort(sort => sort.Add("Vin").Descending())
                    .Transport(tr => tr
                        .Promise("hubStart")
                        .Hub("hub")
                        .Client(c => c
                            .Read("read")
                            .Create("create")
                            .Update("update")
                            .Destroy("destroy"))
                        .Server(s => s
                            .Read("read")
                            .Create("create")
                            .Update("update")
                            .Destroy("destroy")))
                    .Schema(schema => schema
                        .Model(model =>
                        {
                            model.Id(p => p.Vin);
                            model.Field(p => p.Vin).Editable(false);
                        }
                 )
              )
            )

I want to show the TechnicalCampaigns in a column. To be more specific: For each Campaign in List TechnicalCampaigns I want to display the string Campaign.CampaignId.

I have read every single thread in this forum regarding custom columns, customtemplates, using cshtml files as template, or forwarding the list in a customtemplate to a js function, iterating and returning values. 

Absolutely nothing is working. It can't be that hard to display a simple string, or a list of strings, in a column.

 

Any hint would be greatly appreciated!

 

Cheers

Tom

Aggregate problem in 2023.1.425

This is how my grid is defined - and was working before upgrading to 2023.1.425 (this is a Razor page):

@(Html.Kendo().Grid(Model.InvoiceList)
	.Name("ResultGrid")
	.Groupable(ga => ga.ShowFooter(false))
	.DataSource(ds => ds
		.Ajax()
		.ServerOperation(false)
		.Group(gr => gr.Add(gp => gp.CompanyName))
		.Aggregates(aggregates =>
		{
			aggregates.Add(field => field.CheckTotal).Sum();
			aggregates.Add(field => field.CheckTotal).Count();
		})
	)
	.Mobile(MobileMode.Phone)
	.Sortable(s => s
		.AllowUnsort(true)
		.SortMode(GridSortMode.Mixed)
		.ShowIndexes(true)
	)
	.Scrollable(s => s.Enabled(true).Height("auto"))
	.Columns(c =>
	{
		c.Bound(res => res.InvoiceID).Title("ID").ClientTemplate("<a href='/invoicesummary/#= InvoiceID #' target='_blank'>#= InvoiceID #</a>");
		c.Bound(res => res.CheckDate).Title("Check Date").Format("{0:MM/dd/yyyy}");
		c.Bound(res => res.CheckNo).Title("Check No");
		c.Bound(res => res.CheckTotal).Title("Check Amount").Format("{0:C2}");
		c.Bound(res => res.PayTo).Title("Payee");
		c.Bound(res => res.CompanyName).Title("Company Name")
			.ClientGroupHeaderTemplate("#= data.value # - Total: #= kendo.format('{0:C2}', data.aggregates.CheckTotal.sum) # in #= data.aggregates,CheckTotal.count # invoice(s)").Hidden(true);
	})
	.ColumnMenu(m => m
		.ComponentType("modern")
	)
	.Reorderable(r => r.Columns(true))
	.Resizable(rs => rs.Columns(true))
)

Here is the error I am getting:

If I comment out the Aggregates key, everything works fine except I don't have my summarization I need to display.  Like I said, this worked right up until I upgraded the library to the new version.  I also made sure that all of the scripts and CSS are compatible versions.  I have no idea what this message is telling me.  I read something on StackOverflow that suggested adding a parameter-less constructor to the model, but that did not work.

Anything anyone can point would be much appreciated.

Scheduler Adaptive mode

Hi,

When I try to use the adaptive mode in your scheduler adaptive demo https://docs.telerik.com/aspnet-mvc/html-helpers/scheduling/scheduler/adaptive-rendering I can't figure out how to save a new appointment.

I am seeing the same behaviour in my application on mobile devices.

The form for a new appointment opens up but there doesn't seem to be any way to save it.

What am I missing?

Thanks,

Charlotte

Nested Grid Conditional Column

Hi,

I am successfully able to display a nested grid. However there is a new requirement and I need some help.

For simplicity, please consider the following.

Outer grid displays grade information with columns like Grade, Instructor, Room

Inner grid display student information with columns like Name, Race.

So far so good.

Now based a condition in outer grid i.e. if Grade is 12, I would like to add a column to the inner grid called SATAppeared. That is,  I would like a grid like the following

Grade   Instructor   Room

    3          Kelly            20

    Name   Race

      Bo         W

      Li           A

Grade   Instructor   Room

    12          Mac            34

    Name   Race   SATAppeared

      Sue        W            Yes

      Ken        W             No

 

To achieve this, in the template of inner grid, I have put a condition on SATAppeared column. Something like the following but it doesnt seem to work. SATAppeared column doesnt display for any of the grades.

.Columns(columns =>
 {

   columns.Bound(o => o.Name);

   columns.Bound(o => o.Race);

if (Model.Grade == "12")
{
      columns.Bound(o => o.SATAppeared);
}

}

Can you please help. Thank you!

Grid state persistance with column filters or search bar

Hi,

I have set up my grid table to save gridOption on certain events (etc., Sorting, column reorder, filter).

On the document ready, I will load the stringified JSON from the localStorage, and set that as the grid option.

However, I wasn't able to get the table to load properly in a few instances.

1.) When I enter something in the searchbar, the rows will be filtered via the searchbar. 

But if I do sorting to save the grid option and reload it, the following happens:
- The loaded table did not show the previous search item on the searchbar.
- The column filters (with checkbox) only show the filtered list, not the whole list.

I have to manually type in another placeholder text into the searchbar, then remove the placeholder text to "refresh" the table to get the whole list appearing in the column filter.

2.) When I filter some row via the column filter (with checkbox), the rows will be filtered.

But if I do sorting to save the grid option and reload it, the following happens:
- The column filters (with checkbox) only show filtered list, not the whole list.
- When I unselect, the table shows all the rows, but the column filter still doesn't show the whole list, only the previously preselected list.

Can you advise how to get state persistence working with searchbar and column filters with checkbox?

Thanks,
Luke

Problem with Telerik nuget for Asp.Net Core

Hi

After installing Telerik nuget package, my application stopped working.
I added lines to the csproj

<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="4.5.0" />

<PackageReference Include="Microsoft.CodeAnalysis.VisualBasic.Workspaces" Version="4.5.0" />
<PackageReference Include="Telerik.UI.for.AspNet.Core" Version="2023.1.314" />

When I run my application, I get log file looks like that:

2023-04-21 14:49:05.5881 INFO DEVELOPMENT Mode

Telerik Grid MVC

Hello,

Is there any way to change the <input> attr to <textarea></textarea> in popup?

I have gotten as far as doing some basic jquery removeClass and replaceWith. that seems to do the trick it to show the box,

but not the data. 

I know there is an example in how to do it in grid for jquery. But I am trying to see if there is another solution in mvc grid.

Any help is greatly appreciated. 

 

Thank you,

Andi.
