将用户控件添加到用户控件时丢失样式

Question

In my project, I am trying to add a button collection user control to an input based user control. The button uc is going to be added to numerous other controls. The problem that I've encountered is that the button uc is losing whatever css styles that I've attach to it, once it is added to the parent uc. Initially, I had a panel on the parent that would add the button uc when the page was loaded, then I would add the button uc to the panel:

(panel.controls.add(uc)

This did not work, the styling of the buttons were lost. Next, I tried to set the positioning to the button uc and add it directly to the form:

static void SetLocation(Usercontrol uc) {uc.Attributes.add("style","left:425px;top:420px;"); }   
public void SetPage() { button = (uc)LoadControl(button.ascx); SetLocation(buttonuc); this.Controls.Add(buttonuc); }

But, this did not work either, it did not even locate the control properly. My style sheet is already added to the parent uc, and the button uc to be added has its style on that sheet. I don't want to have to manually add the buttons to each uc parent. Thank you for any help. I sure I'm just missing something obvious, but I've yet to come upon a similar issue in a search. Thank you.

In general it is good practice to keep your styles separate from the markup. This makes maintenance easier and it also saves yourself from searching for the reason one of your elements appears a pixel away from where you are expecting (for example... Similar issues can be exasperating).

Do you have the same issue if you set the CssClass attribute for your button(s) and set the styles in a css file for the class?
