How do I associate event code with a Web control that Iveplaced on a Web Form? Can I always just double-click the Web control in thedesigner?

Hi Professor,
The most important thing to consider when developing a webcontrol is that it is located in the proper area of the code and associatedwith the correct event handler. For example, any code that is placed in thepages LOAD event and PAGE_LOAD event handler will execute any moment that thepage is loaded. In the example in the book, we will want the event for thecalculation to be executed when the end-user clicks submit after they haveinput the information. For this reason the code will not be placed in thesection, instead, we create a new event handler for the submit button andassociate the code with that one. (Mitchell, 2010)

The event handler for a Web Control is pretty easy to addand there are a few ways to accomplish this. You do not have to always justdouble-click, but it is the easiest way to accomplish the task.
One of the ways is to go to the design view and double-clickthe page or control for where you want to create a default event handler.Visual Web will automatically create it for you.
The other way to do this is to go to the code editor andmanually place it there. Here you will find two drop down options where youwill select the web control and select the type of event you want to add. Thiswill automatically add the event handler.
According to an article on Microsoft.com, there is anotherway to add an event handler. You can navigate to the design view and select theWeb Control you want to add it to. Then you will go to the properties windowand find the “lightening” symbol. In the box next to the event nameyou can either: double-click for it to auto name it, manually type the name, orclick the drop down to use an existing handler. (How to: Create event handlersin ASP.NET web pages 2014)
The “event code” itself will appear with thelanguage for example:
Partial Class FinancialCalculator
Inherits System.Web.UI.Page
Protected Sub PerformCalcButton_Click(ByVal sender AsObject, ByVal e
As System.EvenArgs) Handles PerformCalculator.Click
End Sub
End CLass
Event Handler ex
(Mitchell, 2010)
You see where it says “handles” that is thegiveaway in the code.

A good database design consists of relational databaseintegrity rules. Data Integrity is important in that it makes sure data staysaccurate and consistent over its life-cycle. These rules are composed of entityand referential integrity. Entity Integrity describes a condition in which alltuples (or rows) within a table are uniquely identified by their primary key.This unique value requirement for the primary key does not allow it to be nullbecause nulls are not unique. Null means invalid, no value, or no bindingforce. For instance, say you make a table with all the names of students inthis class. You have three attributes for every student: first, middle, andlast name. Not all students have a middle name so the value entered for thesestudents would be a null value. An example of entity integrity would be Noinvoice can have a duplicate number, nor can it be null; in short, all invoicesare uniquely identified by their invoice number (Coronel, 2016). Referentialintegrity describes a condition in which a foreign key has a match in acorresponding table or in which the value of this foreign key is null. A nullforeign key makes it possible to not have a corresponding value, but thematching values that are not null make it impossible to have an invalid value.An example of referential integrity would be A customer might not yet have anassigned sales representative (number), but it will be impossible to have aninvalid sales representative (number) (Coronel, 2016).
