引用动态添加的控件
我在form_load里动态添加一控件:
if(tableName   ==   "CostInvoice ")
{
ArrayList   list   =   new   ArrayList();      
list.Add   (new   DictionaryEntry   ( "1 ", "日期 "));      
list.Add   (new   DictionaryEntry   ( "2 ", "货号 "));      
list.Add   (new   DictionaryEntry   ( "3 ", "品名 "));      
list.Add   (new   DictionaryEntry   ( "4 ", "规格 "));      
list.Add   (new   DictionaryEntry   ( "5 ", "单位 "));  
list.Add   (new   DictionaryEntry   ( "6 ", "总成本 "));      
list.Add   (new   DictionaryEntry   ( "7 ", "零售价 "));      
list.Add   (new   DictionaryEntry   ( "8 ", "等级 "));      
list.Add   (new   DictionaryEntry   ( "9 ", "审核 "));
this.comboBox1.DataSource   =   list;
this.comboBox1.DisplayMember   =   "Value ";
this.comboBox1.ValueMember   =   "Key ";
if(colsIndex   ==   "Date ")
{
this.comboBox1.SelectedIndex   =   0;
System.Windows.Forms.DateTimePicker   DateTimePicker1   =   new   System.Windows.Forms.DateTimePicker();
DateTimePicker1.Parent   =   this.groupBox1;
DateTimePicker1.Name   =   "DateTimePicker1 ";
DateTimePicker1.Location   =   new   Point(88,48);
DateTimePicker1.Size   =   new   Size(121,20);
this.Controls.Add(DateTimePicker1);
DateTimePicker1.BringToFront();
DateTimePicker1.Value   =   DateTime.Now;
}
然后在form里的button_click事件里想引用这个textbox，请哪位大侠指点下```

------解决方案--------------------
1、textbox设置为全局变量
2、me.controls........找到该控件


------解决方案--------------------
Control.FindControl是BS下专有的。 System.Web.UI 命名空间


实际上用全局变量最为简单的；
