Dear Telerik,

After opening a JPG file in the Kendo ImageEditor and selecting Save, the image is saved to a .jpg file but in the PNG format instead of the JPG format. This is quite annoying especially because of the increase in file size. For example, a 1MB JPG file is saved to a 6MB PNG file.

Question: How do I request the Kendo ImageEditor to save an image in the same format as the original ?

<div class="k-content">
  @(Html.Kendo ().ImageEditor ()
    .Name ("ImageEditor")
    .HtmlAttributes (new { @class = "w-100" })
    .Height (720)
    .SaveAs (PoSaveAs => PoSaveAs.FileName ("Image.jpg"))
    .Toolbar (PoToolbar => PoToolbar.Items (PoItem =>
    {
      PoItem.Add ().Name ("open") ;
      PoItem.Add ().Name ("save") ;

      PoItem.Add ().Name ("undo") ;
      PoItem.Add ().Name ("redo") ;
      PoItem.Add ().Name ("resize") ;
      PoItem.Add ().Name ("crop") ;
      PoItem.Add ().Name ("zoomIn") ;
      PoItem.Add ().Name ("zoomOut") ;
      PoItem.Add ().Name ("zoomDropdown") ;
    })))
</div>
 

Thanks for your help.

<div class="k-content">
  @(Html.Kendo ().ImageEditor ().Name ("ImageEditor").SaveAs (i => i.FileName ("Image.jpg")))
</div>

Steps to reproduce:

1. Open a JPEG file in ImageEditor.
2. Save the image.

Current behavior:

The image is saved to Image.jpg but the format of the image is the PNG format.

Expected behavior:

The image should be saved in the format of the loaded image. In the example above, the image should have been saved in the JPEG format instead of the PNG format.

This is very annoying especially because of the increase in file size. For example, a 1 MB JPG file is saved to a 6 MB PNG file.

At moment the "ForeignKey" method supports only predicates. Is it possible to implement a String overload (a screenshot is attached)?

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.

Hello,

When you add any kind of filter to the grid, he is wrapped inside span with class "k-filtercell". It would be very usefull to add HtmlAttributes to the html element. Last time i wanted to add class only on the filtercell so i can customize the ui to match our theme. The idea was to have expression for each filter type so i can create css only for the filters. Most of the expressions were ok, because they were wrapped inside Template. But in cases like enum i dont want template, i want only to add class to the filtercell, so i can change it. Its not ok for one types to do the changes with filter expression, for other types to make changes with column.HtmlAttributes(...).

If not HtmlAttributes, at least .Class(...).

Per the documentation for the Grid's Search Panel:

"When the server operations are enabled, you can search only by using string fields."

This is an oddly-specific limitation to have that causes an awkward user experience. Grids in some areas with limited data might use client operations and, as a result, the Search Panel is capable of searching all columns in a Grid. Other areas, however, might have grids with significantly more data and be using server operations for performance reasons. A side-effect of this would mean the Search Panel is incapable of filtering on non-string fields. This not only might lead to unexpected results to an end-user, but also requires the developer to explicitly list each string field that can be searched. If a developer forgets to list only string fields, the default action will be for it to attempt to filter on all fields. If any fields happen to not be strings, you still get a loading indicator as if it's attempting to filter, but the Ajax request silently fails and returns an error 500 behind the scenes.

There are some manual workarounds discussed here, as well as some information as to why this limitation exists. It seems like the problems causing these limitations are known, as are some rough workarounds to get around it. It would be great if we could get some official support to address this limitation so developers aren't left to either work around it on their own or avoid using this feature altogether. This feature would be great if it weren't for this limitation. A single place to quickly and easily type in something to filter on, and have that filter applied against all columns could definitely save some time and be very useful, but with this limitation with a pretty technical explanation (from an end-user perspective), the unexpected mixed results could instead lead to confusion and frustration, and distrust of this feature.

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

Hello,

I have a Gantt that only can have two levels. I guess drag&drop is the best and easiest way to do this (Is it a better solution like editing the order value directly in the TreeList area?)

I want to implement order change in the following way. 

1. If user changes parent task order, he has to drag that parent task (A) and drop on another parent task (B). This way, task A will take task B order value (Shall task B take task A order?). If user drops parent task A on any child task, no order change will happen.
2. Drag of any child task only will be valid in the same parent. I mean, dropping child task in any parent task or in other parent child task will do nothing.

Could you send me any example of this behaviour?

Regards!

Add support for hidden fields. There could be an alternative way of adding them to the Items collection, e.g.

.AddHidden()

Consider the cases when the hidden field is bound to a model field and when it isn't bound to the model. The latter could be a scenario involving antiForgeryTokens: 

<input type="hidden" name="__RequestVerificationToken" value="token" />

In both cases you should be able to set the value of the hidden field programmatically and submit it with the form.

Since support for cancellation token on user vote:

https://feedback.telerik.com/aspnet-core-ui/1357637-duplicate-kendo-mvc-extensions-support-for-cancellationtokens

https://feedback.telerik.com/aspnet-mvc/1357593-todatasourceresultasync-should-support-cancellation-token

was declined and is unplanned.

I would like to implement it by myself.

However most of methods used by code is private or internal, so extending current one is difficult to achieve without copying a lot of existing methods and marking them public. It would be good make them part of public api so implementing own extension to ToDataSourceResult and ToTreeDataSourceResult would be possible. Currently it is not.

Kind Regards

The Kendo Form should include native ListBox editor support including joining and swapping items between two ListBox's using ConnectWith.

To use a ListBox in the Kendo Form currently requires a custom editor which is overly complex.

Currently a DateTime property of a nested object does not get parsed when used as a column in the Grid:

public class MyClass
{
   public MyOtherClass Item{get;set;}
}

public class MyOtherClass
{
    public DateTime CreatedAt{get;set;}
}

and Formatting cannot be applied:

 columns.Bound(p => p.Item.CreatedAt).Title("Time").Format("{0:D}");

Please reference the support ticket number:

The radar chart needs support for 2 CategoryAxis similar to the line and column chart.  In the ticket above, I have shared a screenshot of how the radar chart would look like. Due to confidential reasons, I am not sharing it on the public Feedback portal.
