    variabelSearch++;
}

<td>
    <a asp-page-handler="League" asp-route-varLgPlayerId="@itemP.id">@itemP.naam</a>

Answer 1

首先，您需要一个包含属性的表

variabelSearch

：

public class SearchCount
{
    // Other properties...
    public int VariabelSearch { get; set; }
}

然后在你的后端代码中：

public async Task OnGetLeagueAsync(Guid? varLgPlayerId)
{
    HttpContext.Session.SetString("SessionLgPlayerId", varLgPlayerId.ToString());

    // Assuming _context is your database context, 
    //and you have a known ID for the row you're updating. e.g. your passing varLgPlayerId
    var searchCount = await _context.SearchCounts.FindAsync(knownId);
    if (searchCount != null)
    {
        searchCount.VariabelSearch += 1;
        await _context.SaveChangesAsync();
    }

    Response.Redirect("/LeaguePlayerDetails");
}
