update related data in razor pages
In the visual studio documentation, in "Working with Data in ASP.NET Core", section "Updating related data - EF Core Razor Pages (7 of 8)" I have some trouble trying to understand how the Html.Row() method works in this code:
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<table>
<tr>
@{
int cnt = 0;
foreach (var course in Model.AssignedCourseDataList)
{
if (cnt++ % 3 == 0)
{
@:</tr><tr>
}
@:<td>
<input type="checkbox"
name="selectedCourses"
value="@course.CourseID"
@(Html.Raw(course.Assigned ? "checked="checked"" : "")) />
@course.CourseID @: @course.Title
@:</td>
}
@:</tr>
}
</table>
</div>
</div>
How exactly does Html.Row() method work?
Is there an alternative in updating a related entity in a many to many relationsip?

By default, all strings rendered within an Razor Page (or View) are encoded as HTML - that is all HTML characters are converted to their HTML entity. This is a security measure to help the novice developer form introducing potential XSS attacks into their site.
The Html.Raw method does not encode the string. It is intended to be used for rendering HTML in a Razor Page. I don't understand it's use in the snippet you reproduced. It's pointless. The following will achieve the same thing:
<input type="checkbox" name="selectedCourses" value="@course.CourseID" checked="@course.Assigned" />
If the value of course.Assigned is true, the checked attribute is rendered. Otherwise it isn't.
