When a model property is decorated with data annotation attributes, the RadioButton HtmlHelper does not properly render the data-val and data-val-required attributes on the element.

Expected behavior:  Data attributes should be successfully rendered on the <input> element.

I am looking for an extension to the Grid Columns fluent api that adds .Exportable(true or false).  Exportable(true) would be the default and indicate that this column does get exported when exporting to Excel (or PDF).  Exportable(false) would indicate that the column does NOT get exported.

Imagine the following Grid Definition:

@(Html.Kendo().Grid<Services>
    ()
    .Name("gridMain")
    .Columns(columns =>
    {
        columns.Bound(p => p.ServiceId).ClientTemplateId("rowNumTemplate").Title("Row").Width(50);
        //columns.Bound(p => p.ServiceId).ClientTemplateId("cmdsTemplate").Title("Cmds").Width(125).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceCode).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("xsTemplate").Title("Service / Desc / Code").Media("(max-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("serviceTemplate").Title("Service / Desc").Media("(max-width: 992px) and (min-width: 768px)");
        columns.Bound(p => p.ServiceName).Media("(min-width: 992px)");
        columns.Bound(p => p.ServiceDescription).Media("(min-width: 992px)");
        columns.Bound(p => p.ServiceActive).ClientTemplateId("activeTemplate").Width(60).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("btnsTemplate").Title("View/Edit/Del").Width(150);
        //columns.Bound(p => p.ServiceId).ClientTemplateId("xsCmdsTemplate").Title("Cmds").Media("(max-width: 768px)");
    })
    .Scrollable(scrollable => scrollable.Endless(true))
    .Pageable(p => p.Numeric(false).PreviousNext(false))
    .ToolBar(t => t.Search())
    .Search(s => { s.Field(c => c.ServiceCode); s.Field(c => c.ServiceName); s.Field(c => c.ServiceDescription); })
    .Resizable(resize => resize.Columns(true))
	.ToolBar(t => t.Excel().Text("Excel"))
    .Excel(excel => excel
		.FileName("ABT_Services.xlsx")
		.Filterable(true)
	)
    .DataSource(dataSource =>
    dataSource
    .WebApi()
    .PageSize(Model.GridPageSize)
    .Model(model =>
    {
        model.Id(p => p.ServiceId);
    })
    .Events(events => events.Error("errorHandler").RequestEnd("gridMainRequestEnd"))
    .Read(read => read.Action("Get", "Services"))
    )
)

What I would like to do is define a column like the following:

        columns.Bound(p => p.ServiceId).ClientTemplateId("rowNumTemplate").Title("Row").Width(50).Exportable(false);

In the case above, the "Row" column would not be Exported to Excel.

If you take a closer look at the Columns definition above you will see that the configuration is implemented to support responsive page sizing.  Because the current implementation of Export to Excel does not allow an Exportable(true/false), I get these columns that I don't want in the exported Excel.

Although there appear to be workarounds (like keeping a second hidden grid -- a poor solution at best), none would be as useful to a Developer as defining an Exportable(true/false) as part of the Column configuration.

Thanks for considering my request.

I`m working development and produced I4.0 devices as well app systems since 3 years.  Are Telerick involve in this applications. 

Hello,

We want to create a custom Material theme for our ASP.NET Core web application. We are using the Sass Theme Builder but can only select predefined color swatches for the "Material" base theme. We would like to be able to set custom colors per "subject" just like you can with the "Default" and "Bootstrap" theme. 
Is this possible or are you blocking this on purpose for some reason?

Thank you in advance.

Hi, Any plan to release asp.core with angular 2 template like mvc5 with angular . 

Even when using server side paging some requests can be very long, and may be canceled by the user.  Adding a CancellationToken parameter to the ToDataSourceResultAsync.

I want to design a web page with text and signature input. In Tablet I need to enter the text fields and signature fields using touch pen. I want the web page to allow the touch pen to write comments and signature and save into database

I have a donut chart which represent as a circle and in middle of cricle there is some text, which needs to drilldown, hence click event need which is very necessary

Need support for DataTable in Grid in ASP.NET Core 2.0

Allow general configuration of SuggestionOperator, as is available for Operators.

I can do something like this in GridFilterableSettingsBuilder --

  filterable.Operators(operators => operators
    .ForString(str => str
      .Clear()
      .Contains("contains"))

I would like to also be able to do this -- 

  filterable.SuggestionOperator(FilterType.Contains)

Hi,

We have  a requirement for circled progress bar. Need to know whether you have specifications regarding the requirement or any optimization need to be done within the given framework to get the desired result. Please find the attached file for reference.

Hello,

I'm already using UI for ASP.NET Core, but want to use the OrgChart. I see that it's only in UI for ASP.NET AJAX. Can I get OrgChart to work in my ASP.NET core project?

Thank you.

ToDataSourceResult raises an exception if the DataSourceRequest has Aggregates

the exception says that there is no constructor with the following signature:

Void Microsoft.CodeAnalysis.CSharp.CSharpCompilationOptions(
	Microsoft.CodeAnalysis.OutputKind, 
	Boolean, 
	String,

I traced the error down to the method that causes it :

CSharpCompilation CreateCompilation(SyntaxTree syntaxTree)

Due to changes in the ASP.NET Core framework and how the Authentication is implemented the MVC5 implementation of the SecurityTrimming option became obsolete. 

It would be helpful if the following two options are added to the Telerik ASP.NET Core MVC Application VS template:

1. An option to enable Authorization in the project. It can be enabled in the default ASP.NET Core Web Application, but there is no option to do so in Telerik's template.

2. An option to choose whether CDN will be used for the Kendo UI client resources, or the required files will be registered locally.
