RadzenDataFilter numeric input suffers the same issues as RadzenDataGrid's AdvancedFilter on numeric columns as described in https://github.com/radzenhq/radzen-blazor/issues/1809 (that is, the issue is reproduced only on the hosted environments, influenced by Blazor server lag)

To reproduce

Negative case
Define a RadzenDataFilter with numeric column
Input a value and filter right away

Expected result
Input value is registered in the RadzenDataFilter<>.ToFilterString();

Actual result
Input value is NOT registered in the RadzenDataFilter<>.ToFilterString();

Positive case
Define a RadzenDataFilter with numeric column
Input a value and DO NOT filter right away
Focus something on the page
Do filter

Expected result = Actual Result
Input value is registered in the RadzenDataFilter<>.ToFilterString();

The following script helped to resolve the issue:

function forceUpdateNumericInputs() {
    document.querySelectorAll('.rz-numeric-input input').forEach(input => {
        input.blur();
        input.focus();
    });
}

async Task Submit() // whatever action that leads to reading RadzenDataFilter<>.ToFilterString();
{
    await JSRuntime.InvokeVoidAsync("forceUpdateNumericInputs");
    string filterString = @dataFilter.RadzenDataFilter<>.ToFilterString(); // returns current input
}
