UserControl as unit of reuse - problems

Oliver

hi all -
- I'm probably a) completely wrong b) the umpteenth person too
mention it - but I'm struggling to identify how to best work with
re-usable units of UI on an ASP page.

the problem is really:
1) UserControl - perfect *but* can't be re-used site wide - I *must*
be wrong on this surely...

2) Custom Control - perfect for some things - like sophisticated
controls, but I don't want to use these for everything - I'd like my
site(s) to be build almost entirely of re-usable components

any hints appreciated
Oliver

Oliver,

I think you've got it about right. You are wrong about user controls. They
can be used site wide, but the key here is that they are application
specific. If you site is broken up into multiple applications you'll want to
use server controls instead. Yes, they are more complex, but you can use
them anywhere. That's the trade off.

Another option to create controls quickly is to use inheritance. For
example, if you need a text box to do something special, create a class
library, inherit the text box control already built into .Net and then
modify it.

Sincerely,

Other key differences are:
- Custom Controls can raize their own events
- Custom Controls can be added to the toolbox, both in VS.NET and
Web Matrix.
- The custom properties for Custom Controls can also be set from the
Properties pane in these editors.
For User Controls you'll have to hand-code these properties.

Usercontrol not rendered in table

by: Anon | last post by:

I am programmatically populating a asp.net table control with my usercontrol (PictureBox.ascx) which is basically an assortment of an imagebutton, Label and a Linkbutton. Now while debugging the application i can see that the control is being initialized properly (by setting the imgurl and text values from the db), but for some reason the usercontrol does not show up in the table. Here is the code for the Page: (test.aspx)

Weird difference between UserControl and Form

Hosting the WebBrowser control is easy. Customising it is not.

With aid from around the world I did just that, and put together a comprehensive set of interfaces and enumerations, and I used them on my forms to set up the form as the client site for the browser object implementing...

How do I make a C# UserControl into an OCX file for VB6 use?

by: Dennis Burdett | last post by:

I have a pretty complex control which use to be a C# windows form that I am trying to make into a control that can be dragged onto a VB6 form. I was able to make it into a com class that I could then go to VB6 and add the reference and call the object there without any problems. When I try to make it into a UserControl, I get it to build and it registers itself during the build with no errors BUT I can not add the dll to the vb6...

Reusable UserControl Library in ASP.NET 2.0 RC1

by: Guenter | last post by:

In a blog from Scott Guthrie (http://weblogs.asp.net/scottgu/archive/2005/08/28/423888.aspx) I found a sample to build a UserControl Library inside one ASP.NET project and then deploy it to other projects and reuse it. He suggests that you "publish" the web site to a directory and include this directory into your (second) web site. I tried this but VS (and the aspnet_compiler) complains that my user control now is implemented twice. When...

Loading UserControl using New Contructor

by: Joe | last post by:

Hello All: Do I have to use the LoadControl method of the Page to load a UserControl? I have a class which contains three methods (one public and two private). The class acts as a control server. It "serves" back the required control (either WebControl or UserControl) based on the contents of an xml file. The code in the webform places each control in a TableCell. My problem is that the control server works as far as returning the...

Usercontrol Property loses value at runtime - I don't get it?

by: Johnny Jörgensen | last post by:

Hi y'all I've got a custom control that is inherited from a normal TextBox. To that, I've added a new property that I call "Units", Which is a collection class containing members of a "Unit" class. When I put my Textbox on the form, I can access the "Units" property from the IDE's property grid, use the collection designer and add new "Unit" members to the class.

How to create UserControl as webpart at runtime.

by: =?Utf-8?B?QWtzaGF5?= | last post by:

I'm adding UserControls as WebPart at runtime to a WebPartZone. This is working fine but when I add two or more UserControl instances, the UserControls are overlapping each other i.e. When I add first UserControl it gets added successfully but when I add another UserControl to the same zone, this new UserControl overlapps the first UserControl and it gives a confusing look to the user. Also, the Title area of these webparts shows at...
