In your Razor Page .cshtml file, define a form with checkboxes inside a loop that iterates over a list of items:


    @for (int i = 0; i < Model.Items.Count; i++)
    {
        
            
            @Model.Items[i].Name
        
    }

the corresponding .cshtml.cs file, handle the form submission in the OnPost method:

public IActionResult OnPost()
{
    // Retrieve the selected checkbox values
    string[] selectedItems = Request.Form["selectedItems"];

    // Iterate over all items and check which ones were not selected
    foreach (var item in Model.Items)
    {
        bool isSelected = selectedItems.Contains(item.Id);
        
        if (!isSelected)
        {
            // Do something with the unchecked item
            // For example, add it to a list or perform any desired logic
            // item is not selected
        }
    }

    // Redirect or return a view
    return RedirectToPage("Index");
}

In the code snippet above, Model.Items represents the list of items you want to display checkboxes for. The checkbox values are submitted in the selectedItems array. By comparing the submitted values with the original list, you can determine which checkboxes were left unchecked. In the example, the unchecked items are processed inside the if (!isSelected) block, but you can modify it according to your needs.
