Composite Server Controls and Performance3/2/2005 9:44:04 AM

0/0

In the composite server control that I am developing at present, I am using web methods(Web Service methods) to populate few of the constituent dropdownList boxes.

When I am creating an instance of this composite server control in an ASP page, it seems to be very sluggish.

Are composite server controls themselves sluggish or am I doing something wrong here that is causing things to be so sluggish?

Would encompassing all the functionality into a composite server control that could otherwise be coded into the ASP page itself cause things to be sluggish?

Generally speaking, composite server controls are heavier than rendered ones. Now, that being said, both have their place. I make my decision based on how much use the control will get on a single web page. On my site (www.dotnetdude) I give away several controls one of which is called Web FormField. This one is a rendered control because chances are it will get heavy use in a single form. Another called Web EmailContact, is a composite control because chances are that it will be used once on a single form. The instantiation of controls within a composite control is what makes it heavier. Now, note I said "heavier", not heavy. I am making a comparison to a "rendered" control. In your case, I do believe your web service is causing the slugishness. I have never encountered any slugishness even in some pretty intense composite controls over the Internet. Like I said, when the comparison is made between the two types, rendered ones win out in overall performance. Composite controls still win in the code complexity arena. I think they are a lot more straight forward and easy to follow. If you're control is a custom dropdown, I would probably recommend that you write it as a rendered control since it would probably be used many times in a single page. As a composite control you're going to have two objects instantiated for every instance of your control, one for your control and one for the control inside it. As a rendered control, you bring that down to one. Still, with this example you should not be experiencing slugishness so I think your're problem is elsewhere. I hope this steers you in the right direction.
Good Luck
