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)

As mentioned in this feature request for area-range chart series: "having area 'scatter' support, such as 'scatterArea', and 'scatterAreaRange', like the existing 'scatterLine', is also desirable".

Please see this forum post for details.

Hello,

When I try to create a Telerik UI project for .NET Core 3.0 using menu and grid options the project gets created and runs correctly, however when I try to add a new view or controller there appears to be an issue with the scaffolding (even when creating a partial view) and the creation fails.

Note: I was able to get the project to sort of work only when I added a bunch of libraries it was complaining about (see attached), however the views do not update when I make changes except only when rebuilding which does not seem correct.

Hi!

We're using a drop down list as a grid cell's edit template, but.. our users are unable to properly edit the rows at the bottom of the grid due to drop down list going off the page, and closing when they attempt to scroll.

any ideas?

There is an issue when you copy /paste a bullet list from a Microsoft word document.

• The numbers are not correct (See attached screenshot)
• If you started a new line you don't get a new number for that hierarchical level. Instead, you just get a new line.

Add an option to configure a separate custom editor to be used when the Scheduler's mobile mode is enabled. This would make possible using two different templates at the same time, for example:

.Editable(editable => {
	editable.TemplateName("CustomEditorTemplate").MobileTemplateName("CustomEditorMobileTemplate");
})

This is actually a request for ALL PivotGrid Controls across the Telerik family. Currently only numeric values can be used in a PivotGrid. There are many instances when it can be really useful to perform Pivots on string values. Currently Telerik does not support this feature and I need to use the DevExpress PivotGrid to accomplish my use case. I would like to see Telerik adopt this same functionality.

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.

When you create a Grid using a TModel that inherits from DynamicObject, a type cast exception is thrown when setting the DataSource Model Id property.

public class Metadata : DynamicObject
{
    ...
}  

...
.DataSource(dataSource =>
{
    dataSource.Ajax()
      .Model(model =>
      {
          model.Id("Id");
      });
})

A type cast exception is thrown by the following line in Kendo\AspNet.Core\Kendo.Mvc\UI\DataSource\Fluent\DataSourceModelDescriptorFactoryBase.cs because ModelDynamicDataKey is not generic, so it cannot be cast to IDataKey<TModel>

dataKey = (IDataKey<TModel>)new ModelDynamicDataKey(fieldName, lambdaExpression);

The following code changes fix the issue:

DataSourceModelDescriptorFactoryBase.cs

namespace Kendo.Mvc.UI.Fluent
{
	using System.Reflection;
	using Extensions;

	/// <summary>
	/// Defines the fluent interface for configuring the <see cref="DataSource"/> Model definition.
	/// </summary>
	/// <typeparam name="TModel">Type of the model</typeparam>
	public abstract class DataSourceModelDescriptorFactoryBase<TModel> : IHideObjectMembers
        where TModel : class
    {
        protected readonly ModelDescriptor model;

        public DataSourceModelDescriptorFactoryBase(ModelDescriptor model)
        {
            this.model = model;
        }

        /// <summary>
        /// Specify the member used to identify an unique Model instance.
        /// </summary>
        /// <param name="fieldName">The member name.</param>
        protected void Id(string fieldName)
        {
            IDataKey<TModel> dataKey;
            if (typeof(TModel).IsDynamicObject())
            {
                var lambdaExpression = ExpressionBuilder.Expression<TModel, object>(fieldName);
                dataKey = new ModelDynamicDataKey<TModel>(fieldName, lambdaExpression);
            }
            else
            {
                dataKey = GetDataKeyForField(fieldName);
            }

            dataKey.RouteKey = dataKey.Name;

            model.Id = dataKey;
        }

        protected IDataKey<TModel> GetDataKeyForField(string fieldName)
        {
            var lambdaExpression = ExpressionBuilder.Lambda<TModel>(fieldName);
            var fieldType = typeof(ModelDataKey<,>).MakeGenericType(new[] { typeof(TModel), lambdaExpression.Body.Type });

            var constructor = fieldType.GetConstructor(new[] { lambdaExpression.GetType() });

            return (IDataKey<TModel>)constructor.Invoke(new object[] { lambdaExpression });
        }
    }
}

ModelDynamicDataKey.cs

namespace Kendo.Mvc.UI
{
    using System;
    using System.Linq.Expressions;

    internal class ModelDynamicDataKey<TModel> : IDataKey<TModel>
        where TModel : class
    {
        public ModelDynamicDataKey(string memberName, Expression<Func<TModel, object>> expression)
        {
            RouteKey = "id";
            Name = memberName;
            Expression = expression;
            Value = expression.Compile();
        }

        public string Name
        {
            get;
        }

        public string RouteKey
        {
            get;
            set;
        }

            get;
        }

        public Expression<Func<TModel, object>> Expression
        {
            get;
        }

        public object GetValue(object dataItem)
        {
            try
            {
                return Value((TModel)dataItem);
            }
            catch (Microsoft.CSharp.RuntimeBinder.RuntimeBinderException)
            {
                return null;
            }
        }

        public string HiddenFieldHtml(IHtmlHelper<TModel> htmlHelper)
        {
            return htmlHelper.Hidden(Name, null, new { id = "" }).ToString();
        }
    }
}

Hi,

We have a property EnableHeaderContextAggregateMenu in Radgrid. By enabling this, we can aggregate any column in the Radgrid and show the result value in the corresponding column footer at runtime by the end user.

Do we have similar property in Kendo UI Grid? We need to implement this in Kendo UI Grid which has dynamic column data binding. We had attached a sample code here. Can you please implement the same in the code and revert?

Thanks & Regards,
Shivakumar. K

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.

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

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.

Provide support for the asp-page-handler attribute to call a handler in an ASP.NET Core 2.1 Razor page in addition to supporting controller/action methods.
