Is there an alternate third party tool to build custom server controls graphically, like building a user control?
In fact VS can do this.
1) You can create a Customized Control (*.ascx), this is much more easy, because you do that just developing a normal aspx page by dragging and dropping the normal controls onto the page...
2) Then convert the ascx control into a standard customized control by refering this article, and you can dowlonad the sample there：
