Add a field to the arguments of the OnXRender events for applying Inline styles

I would like to add inline styles to different elements across the components, for example - the Grid Rows and Cells.

<AdminEdit>

The implementation of this might be by adding an args.InlineStyles (this is a sample name, it might not be the same when this is implemented) like the args.Class for the OnRow and OnCellRender events for the Grid.

Title parameter for Update and Cancel GridCommandButtons does not work in Popup edit

<GridCommandButton Command="Save" Icon="save" ShowInEdit="true" Title="Some text here">Some text here</GridCommandButton>

Update and Cancel GridCommandButtons do not honor Caption when using PopUp edit forms.

The "Some text here" will show up as name of button in Inline editing but not in Popup form editing where the default Save button will instead be shown.

If you are in edit mode using InCell, clicking somewhere else inside or outside the Grid should fire OnUpdate if the item is valid. However, if you click on some customly added element in the Grid (e.g. button, icon, dropdown) this will not fire OnUpdate for a valid item.

In Incell edit, clicking anywhere besides the edited cell should fire OnUpdate for a valid input.

---

ADMIN EDIT

---

A possible workaround for the time being - in the OnClick handler of the custom element get the edited item from the Grid State. Update the item and programmatically close the edit mode.

Hello

Telerik.DataSource.Extensions ToDataSourceResultAsync (https://docs.telerik.com/blazor-ui/api/Telerik.DataSource.Extensions.QueryableExtensions) should support Cancellation token as well as https://docs.telerik.com/aspnet-mvc/api/Kendo.Mvc.Extensions/QueryableExtensions.
It would be useful.

Scheduler Appointment Sizing - Event/Appointment Height parameter

Greetings,

I am curious if you intend on offering any means of control for the height of an appointment cell within the scheduler. For us it is in the Timeline view with Resources. I have downloaded the source code and implemented the functionality myself and am willing to share my changes. It ultimately performs three functions:

1. Creates a new parameter on the SchedulerTimeViewBase.cs so that it is end user facing.

2. Alters the code in the ContentTableBase.cs to assign the AllDayAppointmentOuterHeight property with this new parameter's value (plus 1).

3. Alters the AppointmentRendererBase.cs to assign the AllDayAppointmentHeight property with this new parameter's value.

Additional changes are necessary to the Models and Interfaces.

We have used the JS version of this for several years and need the additional real estate on the scheduler. This is the only means that I could figure to alter the height as the position of the cells and resource rows are computed on the back end. Any alterations using a CSS class during OnItemRender will produce cells that overlap each other and/or overflow to subsequent rows.

Customize Upload Text and Icon for Telerik Upload Blazor Component

Customize Upload Text and Icon for Telerik Upload Blazor Component

It is impossible to customize the Text and Icon for the Telerik Upload Blazor Component. It always sans "Select Files". This is not easy to see at a glance.

Requests:

Add a Title attribute to the upload component that lets you change the text from the default "Select Files".
Add the ability to set the Icon on the upload button.

Proposed Code:

<TelerikUpload Title="Upload Files" Icon="@SvgIcon.Upload" ... />

I had to write some hacky JavaScript interop to accomplish this:

function setTelerikUploadButtonText(text) {
    // Finds all the telerik blazor upload components on the page and changes the text of the upload button.

    let replaced = 0;

    const defaultText = "Upload";

    // Find all the buttons with class "k-upload-button". There should be one for each upload component.
    const buttons = document.getElementsByClassName("k-upload-button");

    for (let i = 0; i < buttons.length; i++) {
        // Find the span with class "k-button-text" and change its text.
        const spans = buttons[i].getElementsByClassName("k-button-text");

        if (spans.length > 0) {

            // Add horizontal padding to the span.
            spans[0].classList.add("px-2");
            
            // Change the text.
            spans[0].innerHTML = text ?? defaultText;

            // Insert a font awesome icon.
            spans[0].insertAdjacentHTML('afterbegin', '<i class="fas fa-upload"></i>&nbsp;');
            
            // Track how many buttons were updated.
            replaced++;
        }
    }
    
    console.info("setTelerikUploadButtonText: " + replaced + " buttons updated.");
    
    return replaced;
}

/// <summary>
    /// Finds all the telerik blazor upload components on the page and changes the text of the upload button.
    /// </summary>
    /// <returns>The number of upload components button text that were found &amp; replaced.</returns>
    public static async Task SetTelerikUploadButtonText(this IJSRuntime jSRuntime,
        string text = "Upload Files")
    {
        await jSRuntime.InvokeVoidAsync("setTelerikUploadButtonText", text);
    }

Keyboard keys (left, right arrows, Home, End) not working in GridSearchBox anymore

Hi,

I noticed that using left or right arrow to position yourself between typed text does not work anymore in the GridSearchBox. Neither does SHIFT+left for selecting parts of typed text. Home or End key is also not working.

In previous versions this was still possible.

Can be estabished on the demo pages as well:

Add Ranged Bar/Column Chart Component

Is there any scope to add a Blazor Ranged Bar/Column Chart component as seen in other products:

We attempted to work around this by adding an invisible stacked series underneath our dataset. However, without the Ability to customize the highlighted/hovered series item (telerik.com), we are not able to effectively hide the invisible series from the user. We will have to fall back into the jQuery Kendo UI components once again. Alternatively, are there any other known work arounds to achieve this in Blazor?

Support strict CSS CSP compliance

Telerik UI for Blazor requires unsafe-inline styles in order to render style attributes from the .NET runtime.

Please add support for strict CSS CSP without the need for unsafe inline styles.

===

TELERIK EDIT:

Due to the complexity and required effort to add strict CSS CSP support:

The feature request must gather enough votes.
We may implement it gradually. That's why, everyone who is interested, please specify the exact components and features that you need to be compliant sooner.

date picker invalid

Created by: Joe

Category: UI for Blazor

Type: Bug Report

date picker invalid

There is a date picker bug where if you change the value to something invalid (ex: backspace the date or a portion of it), it will still be bound to the previous date value selected. If you click the picker and select the same date again, it will not register it as a date change and will not fire the value changed event. This causes the field to still show as invalid. To the end-user, it looks as if there is a problem and is telling them it is invalid. I had a customer notice this and they kept trying to reselect the date but nothing would happen.

They eventually typed it manually to fix, which is one way that I agree can be used to resolve. You can also select the wrong date, followed by the right date to get around, but that is a horrible workaround.

What I believe the experience should be is that when selecting the value in the date picker, regardless of what it thinks is in the field, it should fire the change event and update the text of the field to the date selected (and clear the validation message). That is what I'd like to see as a future change. Note that this happens on ValueChanged, but not OnChanged. OnChanged fires too late though, and doesn't work for most workflows.

We put in a hack solution in some operator UIs where it is very important to not have this happen, but it is a pain to do this for every picker, so most in the system are unhandled.

The solution was to have OnOpen and OnBlur both manually trigger ValueChanged (which ends up sending default - 1/1/1901) using a reference for the control. This helps us differentiate if it is these events vs an actual date change. When it is OnOpen/OnBlur, we then reupdate the value in the reference and refresh. Note that you end up having to do this twice to "trick" the telerik logic. So we change to default, refresh, and then change to the correct (or last good value - what is already bound) and refresh. Basically now when they leave the field or click the picker, if there is an invalid value and message, it clears and gets replaced with the last good date. If there is a valid date, it does nothing from the user perspective.

Fields of type long cause errors in the grid editing or when filtering is enabled

If filtering is enabled, the error may prevent the view from rendering similar to NotImplementedException: Unexpected frame type during RemoveOldFrame: None.

Without filtering, an exception is thrown when you attempt to edit a field, similar to Error: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Nullable`1[System.Int64]'.
