We can easily add a photo image with only face in it. 

The request is to add an option in the avatar to detect face from a full body image and auto zoom in to the face to create an avatar from the image provided. This can be controlled using an option in the avatar settings.

Would you be able to implement a more visual aspect for the FileManagement so it look close to this picture.

Attach is the modified Kendo.all.min.js file that you may want to alter so it becomes a permanent in you repository. Changes made for those following :

also here is the C# Thumbnail Class that can be modified if you intend to have you own fabrication of thumbnail as it use to be years ago :-)

using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;

public virtual IActionResult Thumbnail(string path)
    {
        var virtualPath = Path.Combine(_thumbnailFolderRoot);
        var physicalPath = Path.Combine(ConstantVar.webEnv.WebRootPath, virtualPath.Replace('/', '\\'));
        path = Path.Combine(physicalPath, path);
        FileInfo imageInfo = new FileInfo(path);

        int width = 75;
        int height = 75;
        bool KeepRatio = true;

        using (Image image = Image.Load(imageInfo.FullName))
        {

            // Figure out the ratio
            double ratioX = (double)width / (double)image.Width;
            double ratioY = (double)height / (double)image.Height;
            // use whichever multiplier is smaller
            double ratio = ratioX < ratioY ? ratioX : ratioY;

            int newHeight = height;
            int newWidth = width;

            if (KeepRatio)
            {
                // now we can get the new height and width
                newHeight = Convert.ToInt32(image.Height * ratio);
                newWidth = Convert.ToInt32(image.Width * ratio);
            }

            image.Mutate(s => s.Resize(width: newWidth, height: newHeight));
            using (var ms = new MemoryStream())
            {
                image.SaveAsJpeg(ms);
                return File(ms.ToArray(), "image/jpg");
            }
        }
    }

Currently, the Wizard displays any server-side errors that are added to the ModelState in the respective form fields within the Wizard steps (which is great).

The problem is that those errors are not "cleared" when the field is edited/changed. This prevent the form from being posted or the user to move to the next step if the form validation is enabled within the Wizard.

The only way to work with server-side error in the wizard form at the moment is to either disable form validation altogether or to attach an "onchange" event to each of the fields and clear any server-side errors manually once the field is changed.

Both solutions are far from ideal. It would be great if this was part of the default behaviour of the wizard form (like it already is for client-side errors).

Grid row drag and drop capabilities enhancement request.

Currently, in order to drop a row from one Grid into another empty Grid, adding a placeholder row to the empty Grid with custom logic is required: https://demos.telerik.com/kendo-ui/grid/drag-drop

It would be nice to have a more robust drag and drop functionality that doesn't rely on custom logic to such an extent.

 When uncheck "Use localization" while create project the Localization resources are still auto copied while publish the project.

The resources are part of the telerik.ui.for.aspnet.core.yyyy.q.mmdd.nupkg and therefore are copied to the bin folder regardless of the  "Use localization" option. The "Use localization" option controls the availability only of the messages files.

This a feature request for providing another lightweight NuGet which does not contain the localization dlls that could be used for non-localized projects.

Currently, the Gantt allows full customization of its Editing popup:
https://docs.telerik.com/kendo-ui/api/javascript/ui/gantt/configuration/editable.template

But I need to a built-in way to include a new field input only in the Other tab view:

Workaround provided by support team:

.Events(e=>e.Edit("ganttEdit"))

<script>
    function ganttEdit(e){
       var tabstrip = 
       e.container.find(".k-gantt-edit-tabstrip").data().kendoTabStrip;
       tabstrip.bind("activate",function(args){
           if(args.item.textContent == "Other")
           {
              var otherForm = $(".k-gantt-form-other").data().kendoForm;
              var newOptions = otherForm.options;
              
              if(newOptions.items.length < 3)
              {
              newOptions.items.push({
                "field": "Role",
                "type": "string",
               "defaultValue": ""
               });

              otherForm.setOptions(newOptions);
              }
           }
       })
    }
</script>

At this stage, the Serialize() method depends on Newtonsoft.Json:

using Newtonsoft.Json;

namespace Kendo.Mvc.Infrastructure
{
    public class DefaultJavaScriptSerializer : IJavaScriptSerializer
    {
        public string Serialize(object value)
        {
            return JsonConvert.SerializeObject(value).Replace(@"<", @"\u003c").Replace(@">", @"\u003e");
        }
    }
}

Is it possible to remove the dependency and use the System.Text.Json serializer instead?

Please ensure that FilterableMessageBuilder configurations are applied to the Filter's menu when it is placed within a ColumnMenu or expose configurations to control the messages of the Filter menu within the GridColumnMenuMessagesBuilder.

Here is an example REPL that showcases the configuration doesn't have effect

  .Filterable(f => f.Messages(m =>
    {
        m.And("Custom And");
        m.Or("Custom Or");
    }))

unless ColumnMenu() is commented out.

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.

It would be beneficial if the Grid exposes a built-in option for explicitly setting an arrow indicator for selected rows similar to the following:
