I want to know if it is possible to extend the properties of a button and possibly override the render() method?I know how to create a custom server control and that is not what I want to do.I have a lot of web application that need to inject some java script on the button render event based on a new properties value.So what I want to do is extend the properties and hook into the Render method of the button control that ships with .net, I want to do it this way then I can still use the default button control but am able to effect all of the buttons in all of the web applications by simply re-publishing them.Inheriting from the System.Web.UI.WebControls.Button class enables me to add the property but then I have to register the "new" control and I have to go and change all of the buttons in all of the web applications.

I am trying to extend the TreeView and TreeNode class and use it in an .aspx page. My development environment is VS 2005. I put the following code inside of a single .cs file in my App_Code folder:
public class MyTreeview : TreeView {
protected override void TreeNode CreateNode() { return new MyTreeNode(); }
}
public class MyTreeNode: TreeNode { public MyTreeNode():base(){} }
I want to now use my inherited Node and TreeView in my .aspx file. I have the following directive, which is throwing an error -> File is in the special directory App_Code which is not allowed. I tried putting everything into an .ascx file, but I think I am not specifying the class and inheritance directives correctly.

View 4 RepliesHOWTO create ASP.NET C# controls on server side for posted data that had no runat=server on the client.
I have processes needing to post files to a ASP.NET application. These processes must post without runat=server as such:
<form ~~~~ to some ASP.NET/C#/aspx page>
<input type=file name=MY_FILE ~~~>
</form>
On the ASP.NET page, in the Page_Load I would code somethign like this:
[URL]
Here is the trick, the control "fileLIST_FILE" does not exist because the HTML does not have runat=server on it.
If the client did have runat=server the designer.cs would have somethign liek this:
System.Web.UI.HtmlControls.HtmlInputFile fileLIST_FILE;
With all that said, I want to make "fileLIST_FILE" on the fly inside Page_Load fromt he posted name of "MY_FILE".
do not focus on the fact that this is a file upload. I would like to know how to do this for any posted FORM data.

View 1 RepliesI am going to create some custom controls to use them in different projects. Therefore I found some helpful content on microsoft's support sites. These again dealt with overriding the html-render-method, but I am still wondering if this is the most elegant way, because in my opinion this just means outsourcing of some code from the view to the class file.Do I misunderstand the way of how custom controls should be used?
View 2 RepliesI am obviously missing something here and it is driving me batty. I am trying to implement a custom role provider so that I can add some of my own custom code to it. I have created my CustomRoleProvider class, I have inherited the RoleProvider base class and implemented its members. I have made the required changes to my web.config so that my CustomRoleProvider is used. This is all working great.
All of this is wrapped up in a wrapper class as provided by the MVC Membership Starter Kit that I am using and wish to extend.
Now I want to add my own custom functionality.
When I add a function to my CustomRoleProvider I cannot see it or access it.
How do I add functionality to my CustomRoleProvider so that I can use it?
