Hello,

We want to "freeze" the first line of scheduler for scrolling.

It's possible? If don't, have you a workaround to make that?

Thanks

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.

Problem Statement: Unable to set the Filterable operators instead of default's in Tree List .Net Core.

When i add the below to the TreeList :

  .Filterable
          (f => f
              .Operators(op => op
                  .ForString(str => str.Clear()
                      .Contains("Contains")
                      .DoesNotContain("Does not contain")
                      .StartsWith("Start with")
                      .EndsWith("Ends with")
                      .IsEqualTo("Is equal to")
                      .IsNotEqualTo("Is not equal to")
                  )))

Error: 

Severity Code Description Project File Line Suppression State
Error CS1061 'TreeListFilterableSettingsBuilder<dynamic>' does not contain a definition for 'Operators' and no accessible extension method 'Operators' accepting a first argument of type 'TreeListFilterableSettingsBuilder<dynamic>' could be found (are you missing a using directive or an assembly reference?)

Hi

Would like to request to bind Treelist from Datatable with dynamic type

And Totreedatasocure to accomidate for dynamic datatable rather tha at row of static table.

Thank you

Hi there

I am using MongoDb database and storing much of the data as complex objects.

Like this

Company

string     Name

string     Phone

object[]    Addresses

                   object Id

                   string name

                   string line2

                   string town

So the addresses are not stored in normalised tables such as you would have in a typical sql setup

Also I am using Razor pages and not using view models but binding to page model properties

mostly matching the database document. 

One thing I am wanting to do is make the best of such a plan as it saves a lot of coding time.

If I have a telerik control such as a dropdownlist you would typically return an Id and keep the Id

in the database table.  However in the new style of document database it is common to store

the entire object and not just the Id so the problem is if the control returns only the Id then

the developer has to obtain the rest of the object to store away adding the the complexity of the code.

Telerik allows very easy binding of an object to a control and the whole object remains available to use

such as in a dropdownlist to show a name and return say the Id.

An improvement for those using Document style databases with denormalised data would be the option

to simply return the whole object.

@(Html.Kendo().DropDownList()
                .Name("ToBranch") 
                .DataValueField("Id") 
                .DataTextField("Name") 
                .BindTo((Company.Addreses) 
)

So in addition to DataValueField have something like DataReturnObject(true) or something like that

which would send back all the data for the item which you already have sitting right there.

This would very nicely serialise into the pagemodel complex object property and allow proper model validation

which is a problem when you return an Id but the property expects the full object.

I understand all this can be overcome but just a little tweaking by Telerik would be a significant benefit

where your customers are using document style databases such as MongoDb and Azure Cosmos

So..

1 That is my suggestion.

2 Can I currently achieve this somehow?

Implement Recurrence Rule Parser helper that uses the Scheduler recurrenceRule string and parses it in a usable format on the server.

There is already a similar helper for Telerik UI for ASP.NET Ajax.

I was wanting to create a multiselect filter inside the kendo grid that will filter an array column, NOT a simple string column.  Just adding the .Filterable(ftb => ftb.Multi(true)) does display a basic 'multiselect' with just checkboxes in it, which is not ideal , but does work.  But, when you click filter, the grid becomes empty.  I had to use a clienttemplate() function, to return an html object like so:

My column is:

the code for the foreign key doesn't make much sense as it's an array column, but that was pointed to by telerik support on other forum posts.  

So, there must be a way to hook into that column and run some custom code to return to the grid the filtered values?  i've seen examples for jquery, and mvc, but theres nothing for .net core.  This should just work out of the box, as I don't think this is an uncommon need.  Could you give me an example or point me in the right direction?

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;
    using Microsoft.AspNetCore.Mvc.Rendering;

    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;
        }

        public Func<TModel, object> Value
        {
            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();
        }
    }
}

I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.

At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.

What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:

I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode

I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.

Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.

For computations in a custom aggregate function it would be very helpful to have the start and end DateTimes for the current category at hand.  Right now the category parameter just provides a single DateTime which is the start DateTime of the category.  The end DateTime can only be calculated with a workaround provided by Tsvetina

(see this ticket: https://www.telerik.com/account/support-tickets/view-ticket/1386149)

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,

Hello,

Object doesn't support property or method 'syncReady' I am getting this error and not able to resolve that issue. I am using visual studio core and imported Telerik.ui.for.aspnet.core.trial. I also imported the js of Kendo.Ui.Core . but not able to resolve the issue. Please help

Thanks

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.
