Can we have the Image Gallery control like the ASPX AJAX, please? The slide show feature with various transitions is very useful. Thanks.

 I would like to request drag and drop functionality for the Blazor Grid so that rows can be moved up or down with smooth animations. When virtual scrolling is enabled, and a row is dragged to the top or bottom of the grid, the grid should scroll to allow dropping the row to a location that was not initially in the viewport. Also, there should be all the standard drag and drop events that fire when starting, dragging, and dropping a row. Lastly, the drag handle icon should be customizable.

I currently have this functionality in an Angular application using ag-grid, but would like to rewrite the application using Blazor. The only limitation I have run into is this missing functionality in any Blazor grid. Even ag-grid falls short when it comes to nice animations. Here is an example of the animations and scrolling that I would like to have in a grid: https://autodesk.github.io/react-base-table/examples/draggable-rows.

The application is easiestbudget.com.

I hope I'm not the first person to request these features, and I would be delighted to see them in a future version of your Blazor grid.

With the default templates for a blazor project there are options for security.  

We really need this for the telerik blazor templates or a sample telerik blazor projects using the different types of security.

Rendering the TelerikCalendar control produces HTML with ARIA roles like so:

  • tbody - 'rowgroup'
    • tr - 'presentation' <--- this should be 'row'
      • td - 'gridcell'

 

Documentation: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/Gridcell_role

This seems small, but looks bad on accessibility reports, especially when a calendar has 42 'gridcells', The impact is significant when seen in summary.

Alternatively, or in addition, can ARIA roles be turned of for specific controls? In this case including role attributes in the markup is not actually necessary as the roles can be implied by the HTML tags. Including roles that are incorrect is more work for more confusion.

Sometimes it is helpful to allow the user to pick colors for various purposes.

This control can display the RGB value along with allowing them to change the hue/brightness along with the alpha component.

Also the ability to select from a set of predefined colors would be very nice.

Here is a sample project that showcases how you can use Kendo widgets in Blazor and also contains samples of color pickers: https://github.com/telerik/blazor-ui/tree/master/common/kendo-in-blazor

The demos and examples for storing and retrieving GRID state uses the JavaScript localStorage.setItem and localStorage.getItem that work great.  As part of .NET 5 there's a Microsoft equivalent for accessing Local Storage using Microsoft.AspNetCore.Components.Server.ProtectedBrowserStorage.  I've found the behavior of these demos and examples will not work by simply replacing the JavaScript with .NET equivalents.  My experience is getting Circuit Handler exceptions that make these example not work.  

Although not a requirement since there's a JavaScript solution for local storage, I would like to recommend that since you partner closely with .NET team at Microsoft.  That your GRID development team test and provide examples with the Microsoft .NET 5 out-of-the-box local storage solution and resolve any incompatibilities for developers not wanting to use 1st party local storage solutions embedded within Microsoft Blazor.

ADMIN EDIT

I made a sample test and things seemed to work for me, so I made a public example, you can find it in this pull request until it gets merged. I'm also attaching it to this post, but for anyone seeing this after a time - the public repository linked above is a better place to look for this in case more updates and information have been added since the time of writing this.

Hi,

If Telerik can, at some point, develop a design tool like the Radzen Design Time, that would really be nice!

Thanks

I'd like to bind a model with a different field name to the TelerikCheckBoxListFilter in the filter menu.  Currently, this does not work because the Data has to have a member with the same name as the Field, which is used to update the filter descriptors.

 

Current Situation:

I have a single API for retrieving lookup values for the filters, that are always called on-demand (when the menu displays). This also supports cascading filter menus. If I want to supply the values back to filter menu I have to make specific code for each field on the model that I want to filter. For example, if I have a FlightNumber column it looks something like this...

public async Task<IEnumerable<object>> FilterValues_FlightNumberAsync() =>
       (await Service.GetFilterValuesAsync(nameof(MyModel.FlightNumber), GetLastGridRequest()))
       .Select(v => new { FlightNumber = v.Value });

The results of FilterValues_FlightNumberAsync() are then passed in via FilterData below (where @Field would be set to "FlightNumber")

<TelerikCheckBoxListFilter Data="@FilterData" Field="@Field" @bind-FilterDescriptor="Filters" />

This leads to a bunch of tedious code that should not be needed... A specific FilterValues_ function is needed for every column that needs to be filtered

 

What would be preferable:

Being able to use a single method to retrieve filter values. e.g.

public async Task<IEnumerable<object>> FilterValuesAsync(string memberName) =>
       await Service.GetFilterValuesAsync(memberName, GetLastGridRequest()); // returns something like LookupValue[] which is a generic LookupValue { Value  =... } class

 

To not break backwards compat, maybe could have an optional DataField parameter...

<TelerikCheckBoxListFilter Data="@FilterData" DataField="Value" Field="@Field" @bind-FilterDescriptor="Filters" />

This would take in LookupValues and and produce FilterDescriptors with MemberName set to Field

Or maybe event better, use generics and allow a callback to extract the filter value...

<TelerikCheckBoxListFilter Data="@FilterData" GetFilterValue="GetFilterValue" Field="@Field" @bind-FilterDescriptor="Filters" />

where GetFilterValue is a Func<TData, string> for example. 

===========

ADMIN EDIT

===========

We will most likely keep the Field parameter as is (pointing to the field from the Grid data that will be used to take the distinct options) and expose something like TextField parameter that will point to the field form the TelerikCheckBoxListFilter data containing the distinct options/labels.

It would be very nice to be able to have a heatmap style chart where each cell is dependant on the matching x/y values.
In addition each cell is colored or styled based on the x,y combination.

Release 2.28.0

Optimise/Tailor inputs for screen reader users

globally for Telerik Blazor controls/inputs components we would prefer the ability to assign aria attributes. This will enable my organisation's user experience to improve for people relying on screen readers. 

aria-labelledby will enable us to stack labels for inputs in a group.

aria-describedby will enable us to provide additional information in context to an input, without the need for users to jump out of the input and find it.

<TelerikDropDownList Data="@myDdlData" TextField="MyTextField" ValueField="MyValueField" @bind-Value="@SelectedValue"  Width="100%"  />

        public string SelectedValue { get; set; }
        public class MyDdlModel
        {
            public int MyValueField { get; set; }
            public string MyTextField { get; set; }
        }
        protected IEnumerable<MyDdlModel> myDdlData = Enumerable.Range(1, 20).Select(x => new MyDdlModel { MyTextField = "item " + x, MyValueField = x });

I didn't extract this part, but if you make a button that sets SelectValue = null, then the dropdownlist keeps the same value displayed.

Hi,

I have a Blazor grid with multiple selection, and the selection is taken care of using the SelectedItemsChanged event. In that event, I want to check if the selected items satisfy certain criteria, and if not, ignore that particular selection change event.

In the attached sample project, if the EmployeeID is not 6, then the SelectedItems property would get updated. If you see the attached screenshot, that seems to almost work. Employee 6 is not highlighted like the other selected items. But the checkbox is still selected, and that would be confusing since the row is actually not a part of the selected items.

The sample project uses version 2.12, but in another project which runs 2.27, it happens there too.

Please let me know if there's something I missed.

Thanks!

Currently, any datepicker or dropdownlist works great in desktop, but when used in mobile, the dropdowns go off the bottom of the screen and don't fit the window correctly.  Could the dropdowns and datepicker type of the controls have a special "mobile mode" for smaller screen sizes to give a more native mobile feel?  Ex, the standard html select is handled much better by each device including wider options for fingers than the Telerik dropdownlist, but I'd like my site to be responsive for any screen size and not have to use two separate controls.
