The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

working with usercontrols dynamically

Asked by sagir in .NET Framework 2.x, Microsoft Visual C#.Net, Visual Studio

Tags: asp.net c#

Hi,

After switching to ASP.NET 2.0 and understanding the fact that each user control is not a known type as it created and hence the parent which adds the control dynamically can't edit it's properties (since it's not a type) I've figured a way to achieve normal work with user controls (which are added dynamically).

For now I just add a Class to the APP_CODE for each usercontrol which I add to my project and make this class inherit from System.Web.UI.UserControl. Lets say this (app_code) class is called _behindControl and the usercontrol's codebehind class is called usercontrols_behindControl. Then I set the ascx.cs (code behind of the usercontrol on the project - usercontrols_behindControl) to inherit from this _behindControl class.
Then I have to set abstract properties for each webcontrol on the usercontrol inside the _behindControl app_code class. and then override them in the usercontrols_behindControl class itself.

This way when I add the behindControl.ascx dynamically I can edit it's webcontrols (which are strongtyped because of the inheritance through a code inside app_code). This method works. Though it is very not comfortable to add all of this abstract properties for each webcontrol that I want to work with dynamically and then override these properties on the codebehind also.

My question is whether there is a better way to achieve working with usercontrols and modifying their webcontrols and public variables dynamically?

This is a sample code to the way I work now for a simple usercontrol containing a Label.

Thanks,
