I would like to be able to override the No Data message in DropDownList component when there are no elements in the Data.

 

--

ADMIN EDIT

Until this feature is implemented, here is a workaround.

If you already have localization in your project, just set "DropDownList_NoData" key to an empty string in your resources.

If you don't have localization, here are the steps you should do (shortened version of the documentation):

1. Create a class for your localizer: 

public class SampleResxLocalizer : ITelerikStringLocalizer
{
    public string this[string name]
    {
        get
        {
            return GetStringFromResource(name);
        }
    }

    public string GetStringFromResource(string key)
    {
        // this will override only DropDownList_NoData message and it will return other messages as they are
        if (key == nameof(Messages.DropDownList_NoData))
        {
            return string.Empty;
        }

            return Messages.ResourceManager.GetString(key, Messages.Culture); ;
        }
}

 

2. Override the existing Localizer. This step should be done when configuring your services after calling "AddTelerikBlazor()":

 

builder.Services.AddSingleton(typeof(ITelerikStringLocalizer), typeof(SampleResxLocalizer));

Creating custom filter descriptors requires setting the MemberType to match the type of the field they will work with. This should be something we can do through a constructor too, not just by setting the property after creating the instance.

I'm currently migrating a project from ASP.NET MVC to ASP.NET MVC Core.

In the server code I'm using a DataTable from the database which is converted to a DataSourceResult with ToDataSourceResult.

It worked fine in the ASP.NET MVC version, but the same code in the ASP.NET MVC Core version throws an exception when using aggregate functions.

System.InvalidOperationException: 'No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic. '

As we are porting many of our applications from Telerik MVC to Blazor, our clients are complaining about particular features no longer being available.

 

One of which is the multiline edit for incell edit that is available in Telerik-MVC.

 

This feature is nice as it allows the grid to have a very "excel - like" feel to it, with a small triangle in the corner to indicate the cell/view-model has been edited.

 

As is, the user is forced to edit the data line-by-line, and save per line.

In real client work, data is not necessarily modified in this linear/per-row fashion.

 

Take for example, a client has a list of delivery dates which need to be updated down 1 column, current functionality is painful, as you need to edit 1 date, click save, then move onto the next row instead of just moving down the rows and clicking save after you have finished your edits (like you can with Telerik MVC grid).

 

My rationale for this feature add: The "big data" age is upon us - and blazor is very well suited for these types of applications being strongly typed/c# etc; would be great to see Telerik lead in rich data input components for data heavy applications, and the grid is the most core UI component hence should be the most feature rich and performant.

Enable an option for notification/adorner/icon in the Tab Strip tab.  This would allow like a 'notification dot' to alert someone of key information.  The template approach may work, but nice to have a discreet API for this for databinding purposes.

Hello Team;

Is there plan to offer "Card" component where we can create a card with different parts and properties, i.e. Title, Sub-Title, Text, Image, Action buttons and etc.

Something like this:

https://vuetifyjs.com/en/components/cards/#grids

If my memory serves me right, I thought I had seen as part of 2021 R1 roadmap.

Thanks!

Hello team;

Can you please tell us in what version or approximate time of arrival of the new Toolbar?

Suggestion: It would be helpful if the roadmap list is sorted by "In progress" status. This way we can plan accordingly.

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.

In our application, we have the need for aggregate functions in the grid which are determined at runtime, not design time. We were able to get this working for Group footers using a combination of the GroupFooterTemplate element and determining the applicable aggregates in OnStateInit and OnStateChanged. When our team saw that the FooterTemplate element was added, we were excited to bring "Grand Summary" functionality to this grid on top of the existing group summaries. As far as we have been able to determine, however, there doesn't appear to be a way, currently, to add AggregateDescriptors dynamically for the entire grid like we can for groups. We can do the aggregate operations manually against the data source, but this doesn't take into account and filtering which is applied to the grid. We have been unable to find any way of adding AggregateDescriptors for the overall Grid like we can for groups within the GridState's GroupDescriptor property.

Attached are two files: StateInitializationC#Code and gridRazor.txt, which contain relevant snippets of what we are currently doing.

https://docs.telerik.com/blazor-ui/components/grid/filtering?_ga=2.198924911.1399219233.1601890390-1967950312.1584602021#toolbar-search-box

You can add a search box in the grid toolbar that lets the user type their query and the grid will look up all visible string columns with a case-insensitive Contains operator, and filter them accordingly. You can change the filter delay, and the fields the grid will use - see the Customize the SearchBox section below.

-----

I have an int and a string field and would love to be able to let the user search in both at the same time.

 

Workaround is now:

public int number {get; set;}

public string numberString => number.ToString();

public string name {get; set;}

 

But I would love to see it without the need to use the numberString

I would really be happy to see your WPF Diagram Control (https://www.telerik.com/products/wpf/diagrams.aspx) ported to Blazor. 

Do you have any plans to do so?

In a Telerik Grid, we had just implemented the new Grid Footer Template.  However, any built-in filtering (filterrow, filtermenu, searchbox) we use now will cause the grid/page to crash when the input we type does not exist for any row in the grid.  If the input we type does exist, the filtering works correctly.  For instance, if wanted to filter the name "John Smith" and a row exists with that name, then that row will be filtered.  If we typed in "John Smithasdf", then the grid crashes and we receive the following message from the DevTools window:

blazor.server.js:19 [2020-09-21T16:58:12.070Z] Error: System.InvalidOperationException: Nullable object must have a value.
   at System.Nullable`1.get_Value()
   at BudgetPak.Pages.User.Budgeting.HeadcountReview.<>c__DisplayClass0_4.<BuildRenderTree>b__43(RenderTreeBuilder __builder4)
   at Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.AddContent(Int32 sequence, RenderFragment fragment)
at Telerik.Blazor.Components.Grid.GridFooterCell`1.BuildRenderTree(RenderTreeBuilder __builder)
   at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.RenderInExistingBatch(RenderQueueEntry renderQueueEntry)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.ProcessRenderQueue()

From the highlighted text, we deduced the issue had to deal with the Grid Footer template.  Not all of our columns are aggregated on the footer row, so we were thinking that's what the "Nullable object must have a value" message meant.  When we removed the Grid Footer template, the filtering worked correctly.  With one of our other grids, we added a temporary footer grid, and the same crash would occur.

Is there a work-around for this?  The footer template otherwise is great, and we would like to use both that and filtering on our grids.  Please let us know if you need any more info.

Thanks,

Steve
