Hi,

How can I get a label field in the Form ? 

Is it supported out of the box ? Or should I use a span for this ? Or a custom template ?

Hello and good day,

please help with the following problem: there is an ASP.Net MVC grid in use where one column is an enum column. Furthermore, the grid is filtered using row-filter. Now the default behaviour is that the combobox shows the discrete enum values. So far the expected behaviour. But this unfortunately does not allow to display end-user friendly strings, to supress specific values and certainly not to display localised strings. So the questions:

- how can localised values be set at runtime for the individual enum members in row-filter dropdown instead of the simple .ToString() values?
- how are individual enum values suppressed for row-filter? (not every value should be displayed)

To display localized values within the columns cells is no problem due to .ClientTemplate. Thats fair easy. Thanks!

Unfortunately, the documentation at https://demos.telerik.com/aspnet-mvc/grid/filter-row is rather thin and various API links from which one hoped for enlightenment lead to 404-nirvana: 

https://docs.telerik.com/aspnet-mvc/api/Kendo.Mvc.UI.Fluent/GridColumnFilterableCellSettingsBuilder#templatesystemfuncsystemobjectsystemobject
https://docs.telerik.com/aspnet-mvc/api/Kendo.Mvc.UI.Fluent/GridColumnFilterableCellSettingsBuilder#templatesystemstring

These are listed as links on https://docs.telerik.com/aspnet-mvc/api/grid and several others are dead, too.


I would be happy if you could provide me with some sufficient sample code that solves the two problems mentioned above for a grid created by @(Html.Kendo().Grid... within a .cshtml file.
Thank you very much!

Hi Telerik,

I was wondering how I can add custom buttons (serverside code) in the toolbar, with both buttons on the left side as right side (I used to do that with a cuistom class, but that doesnt work anymore since the Telerik update).

For example left a 'Button1' and 'Button2', and right a 'Add' button, and a 'Export Button'.

best regards,

Martin

 

Is it possible to bind a scroll view to an Ajax data source?

Good afternoon, I am not able to make my Html.Kendo (). DatePicker () stay with the date format in "dd / MM / yyyy"

 

            @(Html.Kendo().DatePicker()
                                  .Name("DataAdmissao")
                                  .Culture("pt-BR")
                                  .Value(ViewBag.Dataadmissao)
                                  .Format("dd/MM/yyyy")
                                  .HtmlAttributes(new { style = "width:220px;" }))

        </div>

he returns me the following message and does not show the date  " Index:34 The specified value "02/05/2019" does not conform to the required format, "yyyy-MM-dd" "

 

 

 

I've been trying to accomplish this following several forum threads and this guide: http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/templating/editor-templates but so far I can't make it work. I don't know what I'm doing wrong, since if I use my dropdown list outside the grid it works normally. I can't seem to understand how to bind the dropdown list to a grid column.

This is my grid:
@model IEnumerable<RECON.DAL.Models.Traducciones>
@(Html.Kendo().Grid(Model)
        .Name("Traducciones")
        .Columns(columns =>
        {
            columns.Bound(foo => foo.OrigenId).Title(Global.Origen).EditorTemplateName("_FiltrosTraducciones");
            columns.Bound(foo => foo.Campo).Title(Global.Campo);
            columns.Bound(foo => foo.ValorOrigen).Title(Global.ValorOrigen);
            columns.Bound(foo => foo.ValorDestino).Title(Global.ValorDestino);
            columns.Command(commands =>
            {
                commands.Edit().Text(" ").UpdateText(" ").CancelText(" ");
                commands.Destroy().Text(" ");
            }).Title("Acciones").Width(200);
        })
        .ToolBar(toolbar => toolbar.Create().Text("Nuevo"))
        .Editable(editable => editable.Mode(GridEditMode.InLine))
        .DataSource(dataSource =>
            dataSource.Ajax()
            .Model(model =>
            {
                model.Id(m => m.Id);
            })
            .Create(create => create.Action("Create", "Traduccion"))
            .Read(read => read.Action("Read", "Traduccion"))
            .Update(update => update.Action("Edit", "Traduccion"))
            .Destroy(destroy => destroy.Action("Delete", "Traduccion"))
        ))

 

This is my partial view with the dropdown list:
@model IEnumerable<RECON.DAL.ViewModels.TraduccionesOrigenes>

@(Html.Kendo().DropDownList()
        //.Name("origenes")
        .HtmlAttributes(new { style = "width: 250px" })
        .DataTextField("Descripcion")
        .DataValueField("Id")
        .DataSource(source => source.Read(read => read.Action("GetTraduccionesOrigenes", "Traduccion")))
)

I fill the dropdown list with a stored procedure and outside the grid it works fine.

Now, I don't know if I have to use the EditorTemplateName in the column I want the dropdown list or not, I'd just would like a step by step how to do it so that I can achieve what I want.

Thanks in advance.

Hey all I am very new to Kendo UI but am trying to remake the layout of my companies listbox over to treeview so that I will be able to categorize the items coming in from the api call.

The current code is this:

The above produces the attached image screenshot.95.png.

All that works just fine. I am able to drag over any item and also use the buttons to do the same.

Now here is the problem and where I am currently stuck at not knowing how to go about doing it.

I am wanting to use the treeview with checkboxes so that i am able to put items that are currenbtly in the list into items under their category name.

The api json looks like this:

Hi

I'm trying to set up group management in a grid.
In my case, I'm  

• in ASP.NET MVC
• with dynamic grid (Html.Kendo().Grid<dynamic>)
• full server side operations :

 grid.DataSource(dataSource => dataSource
        .Custom()
        .Type("aspnetmvc-ajax")
        .Transport(t => t.Read(read => read.Action("ReadData", "Grid").Type(HttpVerbs.Post)))
        .GroupPaging(true)
        .Batch(false)
        .AutoSync(true)
        .PageSize(10)
        .Schema(s => s.Data("Data").Total("Total").Model(model => ...))
.ServerFiltering(true)
.ServerGrouping(true)
.ServerPaging(true)
.ServerSorting(true)

I read the following thread which looks a bit like my problem:
https://www.telerik.com/forums/how-do-i-perform-server-side-grouping-and-aggregating

and the answer :
https://demos.telerik.com/aspnet-mvc/grid/customajaxbinding

I was inspired by this to make a POC.
In my grid/ReadData(request), I have something like that

DataSourceResult result = <get data>;
if (!request.Groups.Any()) return result; // No Group
// One group
return newDataSourceResult{
Data=new List<AggregateFunctionsGroup>{
new AggregateFunctionsGroup
{
Key = "Value", Member = request.Groups[0].Member, Items = result.Data
}},
Total=result.Total;
}

Of course, in my test, all rows have the value "Value" in the grouping column.

At runtime, the first time, without group, everything is OK : I have my first 10 records from the table (which has several thousand records)
I drag and drop the column in the grouping bar, and it's ok too : I have my accordion bar with the good column/value
But, when I open the accordion, I have an issue :
Uncaught TypeError: Cannot read property 'notFetched' of undefined
 kendo.all.js:8374  if (lastItem.notFetched) {
 
 I tried again by not returning the Items in AggregateFunctionsGroup
 On open, I receive a readata with a filter corresponding to my column / value and I return my data 
 (the same as during the first execution because all my rows have the same value in the grouping column)
 And I have the same issue.
 
At start, I was with Kendo 2021 R2. But as I saw that there was a fix on this subject, I preferred to install the latest version (R3),
but of course with the same result.

Can you tell me if I am returning bad Data (or Total ?), or if the bug (of R1) is still there?
Unless groups don't work with grid<dynamic>?

Maybe it is necessary to return all the records in the "Item", and not just the first 10? (in my case, several thousand)

Hi,

How can I achieve calling a custom javascript post call (jQuery) when a user enters the Enter key ? (actually independent of which field has the focus at that moment).
Just like with a classic button submit button, but instead calling a custom js function.

Hi,

I get a error message 'The field StartDate must be a date.' when I try to set the DatePicker dateformat, like this:

It seems something goes wrong by validating the date value, because of the format.

My code snippet:

   items.Add()
                            .Field(propInfo.Name)
                            .Label(propInfo.Label)
                            .Editor(e =>
                            {
                                e.DatePicker().Format("dd-MM-yyyy");
                            });

How can I solve this easily, on the server side (preferably not jQuery / javascript fix).
