When specifying a custom format for a numeric text box, like Format="######0", the format is not applied when initially rendered. it seems that it is only applied after updating a bound value.
code snippet:
<SfNumericTextBox TValue="int" @bind-Value="@myInt" Max=1000000 Min=-2 Step=1 Format="######0" Width="200px">
</SfNumericTextBox>
@code{
int myInt = 99999;
}
see example below. See attached solution for full working example.
