User Controls

Introduction

Him will you have a website which you need to repeatedly use a group of controls that record layout that group of controls on these pages may be copying and pasting from one page to the other that work for one of that group of controls had some code it needed to run in reaction to some user of it in that case what you really need is some way to create your own single control that contains all those controls that.

 You could then drop onto a webpage and have it run some code like a normal control what you can do that you can create a user control that is basically a conglomeration of other controls in addition you can also create a custom control which is a control like those you find a little box in this section will investigate user controls in the next section will investigate creating custom controls.

User Control      1

First are user controls these are really like a little page that you embed within other pages these must have a.ASC X extension and you design them as if they were a normal page you can add code to react to events and then you can treat them as a reusable entity there really are intended for use within a single site however that you can create a custom control a custom control is created from scratch these acts and feel like built-in server controls because they are the same thing as built-in server controls all.

 The server controls that are built in to the toolbox are actually Microsoft provided custom controls these each inherit from a base class and that added members as necessary the result is an assembly which contains the control of a custom controls only job really is to render output just like a standard built-in control its job is to spit out HTML when the page is rendered in this section will begin by looking at creating a simple user control imagine that you want some standard user interface design.

 And you liked implemented across all the pages in your website perhaps your standard menu or footer or hitter on every page you could of course critical master page but that's not the point here let's take a look of example I've already created where I have thought of information in a user control how does get there by right clicked on my project chose add new item and then shows Web user control I'm a bit footer is CX 40 Dundas was canceled for now here is forgot is the X if I look at this markup you'll see that it looks like a page really is very much like a page except that has a control directive instead of a page directive all we have on your right now is a style sheet link and then a horizontal rule and some text for looking design it's not totally overwhelming it's just text okay.
