请问我自已新建的控件如何取得style属性？(100分)

[weilt]

我自已建的一个控件，加入了table固定格式，有DropDownList,ListBox,和Button和连接数据库等等，我现在就是不知道如何把我新建的控件加入一些如style属性，以及设置bgColor等属性的设置等等。
请问哪位可以帮帮我呀！
以下是代码：
public class Compontision:Control, INamingContainer
{

private DropDownList DDLCOMP = new DropDownList();

private DropDownList DDLDept = new DropDownList();

private DropDownList DDLSECTION = new DropDownList();

private ListBox SelectUnit = new ListBox();

private ListBox SelectedUnit = new ListBox();



public string Value
{
get{return SelectUnit.SelectedValue;}
}

public override string ID
{
get
{
return base.ID;
}
set
{
base.ID = value;
}
}

public override Page Page
{
get
{
return base.Page;
}
set
{
base.Page = value;
}
}

public override bool Visible
{
get
{
return base.Visible;
}
set
{
base.Visible = value;
}
}

protected override void OnInit(EventArgs e)
{
base.OnInit (e);
}

public override Control FindControl(string id)
{
return base.FindControl (id);
}

public override ControlCollection Controls
{
get
{
return base.Controls;
}
}




protected override void CreateChildControls()
{
this.Controls.Add(new LiteralControl("<table cellSpacing='0' cellPadding='0' border='0' style='LEFT: 100px; POSITION: absolute; TOP: 100px'>"));
this.Controls.Add(new LiteralControl("<tr>"));
this.Controls.Add(new LiteralControl("<td style='HEIGHT: 19px'>"));



DDLCOMP.AutoPostBack = true;
DDLCOMP.SelectedIndexChanged += new EventHandler(this.DDLCOMPSelectedChanged);

this.Controls.Attributes.Add("onmouseup", _
"this.style.backgroundColor='Gainsboro';" + _
IIf(isIE, "this.style.borderStyle='outset';", "").ToString())

是不是用这种方法有使用此自建控件时可以临时再定义其style 属性？

[bitsbird]

你的意思是不是重写这些控件样式?
override protected void OnPreRender(System.EventArgs e)
{
base.OnPreRender(e);
this.CssClass = "classTextNotEmpty";
}
.classTextNotEmpty
{
border : solid 1px #E4EAF2;
border-bottom-color:1F4D75;
color : Black;
font-size:11px;
height : 18px;
width:100%;
font-family:Tahoma;
background : #E4EAF2;
}

[weilt]

是的，我想我自已做的控件能够像.NET自还的控件一样的控制它的STYLE 属性，而不像现在 一样只能在控件里面写好了它的大小，位置，什么的

[leoAAAA]

例如,
Lable l1 = new Lable();
l1.BackColor=Color.Red;

TableCell tc=new TableCell();
tc.BorderColor=Color.Blue;

Table t1=new Table();

t1.BorderColor=Color.Blue;
//t1.BorderStyle=BorderStyle.Solid;
t1.GridLines=GridLines.Both;

或者用css

[bitsbird]

Button1.Style=""
