The upload status hangs on "Uploading..." if the Upload component is hosted in a Dialog and the OnSuccess event is used.

<AdminEdit>

As a workaround, you can host the Upload in a Window, where this issue is not present

</AdminEdit>

I would like to have my users click my own button or element to trigger the file select dialog that you get from clicking the "Select Files..." button on the Upload component.

A workaround is to use a function like this

window.customUploadClick = function () {
    $('.k-upload-button input').trigger('click');
}

Completed with 3.0.0 release

If you are not using jQuery already, you don't have to add it for this, standard browser API can do this too:

@inject IJSRuntime _js

<script suppress-error="BL9992">
    window.customUploadClick = function () {
        document.querySelector(".k-upload-button input").click();
    }
</script>

<TelerikButton OnClick="@InvokeSelectClick">invoke click</TelerikButton>

<TelerikUpload></TelerikUpload>

@code{
    async Task InvokeSelectClick()
    {
        await _js.InvokeVoidAsync("customUploadClick");
    }
}

Please provide item templates for the file list, similar to:

• https://www.telerik.com/kendo-angular-ui/components/uploads/upload/templates/
• https://demos.telerik.com/kendo-ui/upload/templates

I am trying to upload files to an URL that is not in my control and it requires the PUT HTTP method. The Telerik Blazor Upload always uses a POST.

I imagine API like this would be nice:

        <TelerikUpload SaveUrl="@SaveUrl" SaveMethod="PUT">

        </TelerikUpload>

ADMIN EDIT

In the meantime, there are two possible solutions:

• Upload the file to your own server that can accept POST and use that server to upload to the third party. This can help hide URLs and security from your end users as well.
• Implement a FileSelect type of component to get the file in code and upload it with your own HTTP request from C#.

<TelerikUpload SaveUrl="@SaveUrl"
                               RemoveUrl="@RemoveUrl"
                               AllowedExtensions="@( new List<string>() { ".pdf", ".docx" } )"
                               OnSelect="@OnSelectHandler"
                               OnCancel="@OnCancelHandler"
                               OnRemove="@OnRemoveHandler">
                </TelerikUpload>

When the AllowedExtensions is set for the Telerik Upload control, it is expected that the File selection dialog box should filter the files by the file types in the Allowed extensions only. However, the dialog shows all files.

ADMIN EDIT

This will likely be exposed via the accept attribute the <input type=file> exposes. Note that it requires MIME types, not extensions.

At the moment, the extension can be filtered only after the file is selected: https://docs.telerik.com/blazor-ui/components/upload/validation.

-----

I would like to have the upload component but change the text on the button (or maybe its entire content through a render fragment template) through a Parameter on the component level.

At the moment I can only do this through localization for all components.

Is it possible to programmatically perform actions on the uploader, such as to remove files, rather than having to click on the remove button on each uploaded file?

ADMIN EDIT

Might be related to the ability to have initial files shown in the list: https://feedback.telerik.com/blazor/1485660-initial-files-in-blazor-upload.

At the moment, you could try using JS Interop to loop over the list, determine which file you want to remove and .click() its remove button. Here is a basic example of getting the buttons to click the second one. You could traverse the DOM to get the file name, or you could keep a collection of the files to use indexes in a fashion similar to this example.

@inject IJSRuntime _js

@* move this script to a correct location it's here as ahack to make the snippet shorter and easy to copy  *@
<script suppress-error="BL9992">
    function removeSecondFile(){
        var deleteButtons = document.querySelectorAll("li.k-file button span.k-delete");
        if(deleteButtons && deleteButtons.length > 1){
            deleteButtons[1].click();
        }
    }
</script>

<TelerikUpload AutoUpload="false" SaveUrl="my-endpoint"></TelerikUpload>
<TelerikButton OnClick="@RemoveSecondFile">Remove second file</TelerikButton>

@code{
    async Task RemoveSecondFile()
    {
        await _js.InvokeVoidAsync("removeSecondFile");
    }
}
