It would be VERY helpful if you integrated "Prevent the Grid from wrapping text in multiple lines and show ellipsis" into grid as an option (so we would not have to write separate code and style).

I think this is one of the most needed features since grids almost always have data that wraps line.

At the moment, typing with the keyboard focuses the first item that starts with the last letter you pressed. To focus the next one you should either use Down Arrow, or type the same letter again.

I would like it to behave like the regular <select> or like a combo box with filtering - typing characters quickly should highlight the item that begins with all those characters, instead of using only the first letter.

When using the OnRead event of the ComboBox there is no way to retrieve the selectedItem because the list of items that is populated is internal.

There are 2 workaround but they are not ideal:

- Saving the list of items returned by the OnRead event into a parallel list and then retrieve the selectedItem from it -> the problem is that there will be 2 identical lists in memory and, if scaled, might cause problems:

CachedSitesList = result.Items;

args.Data = result.Items;
args.Total = (int)result.TotalCount;

- Retrieving the selectedItem by calling the DB using the Id of the item -> the problem is that it's one more request to add to the DB and the performance is going to decrease if scaled, also it seems useless as the item is already present in memory.

We suggest adding a function to return the selectedItem to improve performance and scalability of the component.

We are looking to port an angularjs web application to Blazor and I didn't see the diagram component similar to the one found in Kendo UI. It would be nice to see a viso-like component in UI for Blazor.

Thank you.

We have a form with multiple TelerikEditor controls bound via @bind-value. The issue arises when there are more than 2 TelerikEditors; the performance is significantly impacted for all input fields. Typing experiences delays, making fast typing impractical.

This performance degradation is attributed to the fact that the page undergoes frequent re-renders when typing into the input fields. Interestingly, this behavior does not occur when TelerikEditor is excluded from the form or page.

While the DebounceDelay property in TelerikEditor helps improve its performance, it does not extend its influence to other input fields in the form or page. Are you familiar with this issue, and do you have any recommendations for addressing or mitigating it?

I would like the TreeList to support row virtualization. It will be useful when working with large data.

I would like to be able to optimize the rendering of the TreeView component with a feature similar to the Row Virtualization in the Grid.

When scrolling up in a virtual Grid, the rows "above" are not be kept or loaded like when scrolling down, and it takes a while before they get loaded and shown. This behaviour is not very user friendly and should be corrected.

Create a word style component.

Currently my wpf desktop app uses a editor style component and refreshes a crystal reports window component to show edits made to a pre created document. We use this to create quote letters using custom legal jargon.

I am in the process of moving that program to Blazor. A word component that i can wrap our custom texts around and buttons in the title bar for pasting our prefomatted text would be so much better than our current setup. 

Could this be added to the roadmap?

Looking through the examples I can't find one with SelectionMode="GridSelectionMode.Multiple" and using a RowTemplate.

ADMIN EDIT: This is not a bug in the component, an example of how this can be implemented by the app is available in the comments.

I'm not sure what I should be binding my checkbox to so it accurately reflects selection state.

From the RowTemplate Example adding SelectionMode:

<TelerikGrid Data=@GridData


SelectionMode="GridSelectionMode.Multiple" Height="@Height">

<RowTemplate Context="product">  @*Trying to inspect what is generated in the examples I came up with this, but not sure what to bind to checked*@

<td role="gridcell" colspan=0 data-col-index="0">
                        <input class="k-checkbox k-grid-checkbox telerik-blazor" type="checkbox" />

<td> <img class="rounded-circle" src="@($"images/{product.ProductId}.jpg")" alt="Alternate Text" /> @product.ProductName </td> <td> @(String.Format("{0:C2}", product.UnitPrice)) </td> </RowTemplate> <GridColumns> <GridColumn Field=@nameof(Product.ProductName) Title="Product Name" /> <GridColumn Field=@nameof(Product.UnitPrice) Title="Unit Price" /> </GridColumns> </TelerikGrid>

I am using Telerik Grid in our project and I have enabled the feature Reorderable="true". At GridColumnMenuSettings I am getting the following options:

Set column position :

  • Move Next 
  • Move Previous

Those options are commonly showing for all columns but I want to disable "Move Next" option for the last column and "Move Previous" option for the first column as these options are not applicable to the corresponding columns.

Type: Feature Request


I would like to add a CSS-Class to some items in my TelerikDrawer control. Since the ItemTemplate only controls the contents and the Template is overkill as it overrides the rendering for the entire drawer contents, I was wondering whether there was any support for adding custom CSS classes to items (similar to how it is described for Angular here:

Category: Grid
Type: Feature Request

The request targets a hierarchical Grid where some items are expanded - when I edit a parent item and then update it, all the respective detail items collapse.

Please add support for persisting the expanded state of the items.




The feature applies to the other data operations as well (for example, paging, sorting, filtering etc.).

Would be great to have the ability to customize the text of the Dialog Factory buttons, especially for Confirmation. We could use a Custom window but all we need to do is change the buttons and the Dialogs feature is perfect.

Category: FileSelect
Type: Feature Request

UI for Blazor version 5.0 improved the FileSelect Stream performance by removing legacy code that meant to support older .NET versions.

However, the Stream performance is still worse and the component works slower, compared to the standard Blazor InputFile.

Category: RadioGroup
Type: Feature Request

I would like to be able to disable one or more radio buttons in the RadioGroup.



The CSS workaround below uses the nth-child selector. In the example, I have disabled the third and fourth options and you can use it as a base and extend that sample in your own application.

    .disabled-items li:nth-child(3),
    .disabled-items li:nth-child(4) {
        outline: none;
        cursor: default;
        opacity: 0.6;
        -webkit-filter: grayscale(0.1);
        filter: grayscale(0.1);
        pointer-events: none;
        box-shadow: none;

<TelerikRadioGroup Data="@GenderOptions"

    TelerikRadioGroup<GenderModel, int?> RadioGroupRef { get; set; }

    int ChosenGender { get; set; }

    List<GenderModel> GenderOptions { get; set; } = new List<GenderModel>
        new GenderModel { GenderId = 1, GenderText = "Female", isEnabled = true },
        new GenderModel { GenderId = 2, GenderText = "Male", isEnabled = false },
        new GenderModel { GenderId = 3, GenderText = "Other", isEnabled = true },
        new GenderModel { GenderId = 4, GenderText = "Prefer not to say", isEnabled = true },

    public class GenderModel
        public int GenderId { get; set; }
        public string GenderText { get; set; }
        public bool isEnabled { get; set; }

Expose an OnItemRender event, which is raised for each menu item. The args will allow setting a Class, that will be applied at the topmost element of the item iteself, allowing full customization, as well as PopupClass, which is applied to the topmost element of the item popup.
