There doesn't seem to be a way to deselect the selected row either by clicking on a selected row again or by two-way-binding and setting it to an empty list.

This would be pretty handy as currently the only way that makes sense for me is to make no use of selection mode at all.

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');
}

ADMIN EDIT

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");
    }
}
