Hi, 

could you help me about following calculations in the grid for telerik asp.net core (C#)

IN - OUT = SALDO (for row index 0)
IN - OUT = SALDO (for row index 1) + SALDO from previous row

image example attached

My grid only show max 20 row

It does not matter if paging is disabled

<kendo-grid name="grdAfdeling" selectable="true" on-change="onChangeAfdeling" deferred="true">
            <datasource server-operation="false" type="DataSourceTagHelperType.Ajax">
                <transport>
                    <read url="/Medarbejder/Hent_Medarbejder_Afdeling" data="hentAfdID" />
                </transport>
            </datasource>
            <scrollable enabled="false" />
            <columns>
                <column field="ID" hidden="true" />
                <column field="Navn" title="Navn" />
                <column field="Lokalnr" title="Lokalnr." width="80" />
                <column field="Mobilnet" title="Mobil Lokalnr." width="90" />
                <column field="Mobilnr" title="Mobilnr." />
                <column field="Email" title="Email" />
                @if (User.IsInRole("w_Paaroerende"))
                {
                <column field="Familie" title="Familie" encoded="false" />
                }
                <column field="BilledUrl" title="Billed" template="<img src='#= BilledUrl #' alt='image' width='70' />" />
            </columns>
        </kendo-grid>

I using VS 2017 15.9.3 + asp.net core + mcv ( + razor )

created the project with telerik Project Asp.net core + Grid selection.and created 3 times with the sass theme generator a template and replaced in

_Layout.cshtml the stylesheet

<environment names="Development">
    <link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" />
    <!--link rel="stylesheet" href="~/css/site.css" /-->
    <link rel="stylesheet" href="~/css/all.css" />
</environment>
<environment names="Staging,Production">
    <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.6/css/bootstrap.min.css"
          asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css"
          asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" />
    <!--link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" /-->
    <link rel="stylesheet" href="~/css/all.css" asp-append-version="true" />
</environment>

but anyhow the Grid looks ugly in the footer any time.

i found this blog https://www.telerik.com/blogs/getting-started-telerik-ui-for-asp-net-core-and-bootstrap-4

but i do not understand how to do the update

>>No matter how you choose to manage your dependencies, the default layout (i.e _Layout.cshtml) should contain references to them. The default layout >>defines a top level template for views in your web application. These references include the following:

where to store the references , where to reference them etc..

it´s a little bit confusing me so please is there some better help tan this how to update or maybe it´s not needed anyhow to solve the grid ui problem ?

thanks br thomas

I am having some strange issue with cascading binding.

This code here does work:

But this one does not:

I don't know why I cannot se the tag helper here. 

The first dropdown I got to work with tag helper but the second one not. 

As you have read the title. I want to add a variable in my title. When I put a property in my model, and also define the model in my div. It still gives me the error:

The name 'property' does not exist in the current. But when I add series for example I can do Model => Model.propname Why is it not possible to do this? sTotalCount is in Model2
The code:

Hello,

I want for my bar to have a Y-axis line. Just the same as this Dojo Example

I have removed the first plotband so only the line will be visible. But then I see this:

Is there a way to just set it at 30000 and not to 35000? 

Kind regards

Hi! I'm using IFrame windows for modal forms and want to be able to resize the modal window dynamically, based on the size of the calling parent.

Here is the calling parent:

And here is the window page:

I am able to get the width and height to set to static values (400x400) and recenter, but I'd like to get the height dynamically, as in the commented lines. 

Any help would be much appreciated!

I cannot figure out how to color the background of the Toolbar in a Kendo UI Grid.  I can style the buttons but I want the <div> or panel behind the buttons to be a different color that what you see in the attachment, white.

Thanks

Dear,

Firstly, I downloaded the test grid file with https://www.telerik.com/forums/razor-pages-grid-binding-with-ajax-support, I tried, the grid works.

when I added "services.AddAntiforgery(o => o.HeaderName = "XSRF-TOKEN");" to ConfigureServices,the dome of grid doesn't work， it is no response to call the read and update handler.

Test Env:VS2017 .net core 2.1 Razor, Telerik:Ver 2018.3.1017

I would appreciate it if you can give me some ideas.

thanks.

        ......

          services
                .AddMvc()
                .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
                .AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
                
            services.AddAntiforgery(o => o.HeaderName = "XSRF-TOKEN");

            services.AddKendo();
        }

razor page code

<h2>TestGrid</h2>

@inject Microsoft.AspNetCore.Antiforgery.IAntiforgery Xsrf

@(Html.Kendo().Grid<WebApplication8.Models.Customer>().Name("grid")
                                            .AutoBind(false)
                                            .Groupable()
                                            .Sortable()
                                            .Columns(x =>
                                            {
                                                x.Bound(c => c.Address);
                                                x.Bound(c => c.Name);
                                                x.Command(c => c.Edit());
                                            })
                                            .DataSource(d => d.Ajax()
                                                   .Read(r => r.Action("Pages", "Contact", new { handler = "ReadRecords" }).Type(HttpVerbs.Post))
                                                   .Update(u => u.Action("Customer", "Index", new { handler = "UpdateRecord" }).Type(HttpVerbs.Post))
                                                   .Model(m => m.Id(id => id.CustomerId))
                                                .PageSize(10)
                                            )
                                            .Pageable()
)



<script>
    $(function () {
        var grid = $("#grid").data("kendoGrid");

        grid.dataSource.transport.options.read.beforeSend = function (req) {
            req.setRequestHeader('RequestVerificationToken', $('input:hidden[name="__RequestVerificationToken"]').val());
        };

        grid.dataSource.transport.options.update.beforeSend = function (req) {
            req.setRequestHeader('RequestVerificationToken', $('input:hidden[name="__RequestVerificationToken"]').val());
        };

        grid.dataSource.read();
    })
</script>

second, If I removed "services.AddAntiforgery(o => o.HeaderName = "XSRF-TOKEN");" from ConfigureServices, The Grid can work fine, but the ajax event doesn't work, I really don know the why.

<input asp-for="SearchString" onchange="HandlerTest()" class="form-control" />

<script>
    function HandlerTest() {


        $.ajax({
            type: "POST",
            contentType: "application/json",
            url: "About?handler=LoginIn",
            beforeSend: function (xhr) {
                xhr.setRequestHeader("XSRF-TOKEN",
                    $('input:hidden[name="__RequestVerificationToken"]').val());
            },
            //data: { UserName: $("#UserName").val(), PassWord: $("#PassWord").val() },
            success: function (response) {
                console.log(response);
            },
            failure: function (response) {
                alert(response);
            }
        });
    }


</script>
