Also, I really appreciate the download in vb.net: it's not often that I find tutorials in vb when it comes to the latest .net subjects.

Even these tutorials are well explained and to the point, but some knowledge of ASP.Net controls, their events, relational database concepts and even LINQ concepts.

I come to microsoft with the idea of doing things quicker and I find an abstruse language that makes no sense to me, a destruction of the DBMS model, a bunch of artificial entities and controls adding more complexity to everything, SQL queries that are completely upside down starting with from and ending with Select, I find this completely rubbish, overcomplicated and does not spare me anytime at all.

This is very typical from American schooling, they get you to copy and paste to speed up productivity, but if one does not understand the molecular structure of what he is doing, his web is going to get hacked by those of the countries where they understand the very roots of what they are doing. So, we cannot just copy and paste to make it look quick and easy because we get lost and dont know anymore what we are doing. The very least a detailed comment of every line should be here for those who come here to learn.

thanks

protected void InstructorsGridView_SelectedIndexChanged(object sender, EventArgs e)

{

}

protected void InstructorOfficeTextBox_Init(object sender, EventArgs e)

{

instructorOfficeTextBox = sender as TextBox;

}

AND THIS TOO:

protected void InstructorsGridView_SelectedIndexChanged(object sender, EventArgs e)

{

ClearStudentGradesDataSource();

}

I have ended up completely confused about so many entities, controls, I am completely lost and cant remember what entity was for or what its name was or to which control it related. A nightmare.

We have seen so far a dozen entities plus controls and about 300 lines of code spread across many pages. All this can be accomplished with less than 10 lines using a JQUERY plugin for datatables which already sorts, filters, and edits and paginates. Then on clicking on the row you pas the ID to the other table and that is it. I am not any of those anti microsoft at all, in fact i was very excited in trying to learn visual studio, but I am desillusioned at seeing how complicated it gets to do simple things. In fact the first tutorial had 21 different comments, and by now just 3 persons are still here and by the end of the tutorial only one person has made it to that.

Also, I liked that LINQ queries were part of the example too. This tutorial is turning out the be very comprehensive.

This is because the first <DIV> must have the following attributes:

<div style="float: left; margin: 20px")>

I'll use the ideas of this tuturial for my project. I also want to make a note of LING using.

This tutorial neglected to mention that.

It is a fantastic brief and well explained tutorial with a very good practical example. Can I claim that I have developed a better and featured database oriented app than Entity framework?

My database oriented application maps database entities to c# objects. It creates better facilitated input forms. It provides extended searching and reporting features with efficiency.

Saying after being familiar with EF. Can you help me to make my app recognized if it would really deserve.

I'm having some trouble with this step though, when I add the first parts of code to instructors.aspx my OfficeAssignments doesn't have definitions for AddObeject, CreateOfficeAssignment or Delete Object.

Not sure if it is a result of me missing something or because I am running in Vis2012. (Is there good updated tute anywhere yet for VS2012 and the new EF yet?)
