后台用C#中的Attributes

第一种写法：控件ID名.Attributes.Add(“事件名称”，“JS方法”);

如：一个按钮控件Button1.Attributes.Add(“onclick”，“return confirm('确认？')”);

另外还可以控制某一个文本框的属性，比如文本框的大小，宽度等。

如：TextBox1.Attributes.Add(“width”,“80px”);

this.Panel1.Attributes.Add("style","display:none");
this.Panel2.Attributes.Add("style","display:block");

在gridview中行中：

row.Cells[this._page.Unit.ProgUnit.FieldList.GetIndexByKey("CJZTBH")].Attributes.Add("style", "font-size:16px");
row.Cells[this._page.Unit.ProgUnit.FieldList.GetIndexByKey("CJZTBH")].BackColor = Color.LightSteelBlue;
