Possible bug with for loop

[stsrki]

I have a SimplePagination component with just the basics:

<Pagination>
    @for ( int i = 0; i <= ( TotalItems / PageSize ); ++i )
    {
        <PaginationItem>@i.ToString()</PaginationItem>
    }
</Pagination>
@functions{
    [Parameter] int TotalItems { get; set; }

    [Parameter] int PageSize { get; set; } = 10;
}

Use case:

<SimplePagination TotalItems="5" />
<SimplePagination TotalItems="15" />
<SimplePagination TotalItems="45" />

When rendered I get this:

But if I store the page number inside of temp var I get the expected result:

<Pagination>
    @for ( int i = 0; i <= ( TotalItems / PageSize ); ++i )
    {
        var pageNum = i.ToString();
        <PaginationItem>@pageNum</PaginationItem>
    }
</Pagination>
@functions{
    [Parameter] int TotalItems { get; set; }

    [Parameter] int PageSize { get; set; } = 10;
}

I guess that ChildContent inside of my PaginationItem will only get the reference to the ToString() function instead of it's return value.

Is this expected behavior ?

Yes, this is expected. See https://github.com/aspnet/Blazor/issues/1402, https://github.com/aspnet/Blazor/issues/764, https://github.com/aspnet/Blazor/issues/665
