关于控件数组的一些操作

1.利用递归遍历所有控件

 1  // 递归遍历所有的控件(TextBox)
 2           public   static   void  LoopingControls(Control myControl)
 3          {
 4               foreach (Control frmcontrols  in  myControl.Controls)
 5              {
 6                   if (frmcontrols.GetType().ToString() == " System.Web.UI.WebControls.TextBox " )
 7                  {
 8                      ((TextBox)frmcontrols).Enabled = false ;                    
 9                  }
10                   if (frmcontrols.HasControls())
11                  {
12                      LoopingControls(frmcontrols);
13                  }
14              }
15          }    
16 
17  // 示例调用
18  LoopingControls(Page);        

2.控件数组的操作

 1  // 控件数组
 2     < asp:textbox id = " txtOpinion1 "  runat = " server "  Width = " 100% "  BorderStyle = " None "  Height = " 60px " ></ asp:textbox >
 3     < asp:textbox id = " txtOpinion2 "  runat = " server "  Width = " 100% "  BorderStyle = " None "  Height = " 60px " ></ asp:textbox >
 4     < asp:textbox id = " txtOpinion3 "  runat = " server "  Width = " 100% "  BorderStyle = " None "  Height = " 60px " ></ asp:textbox >
 5     < asp:textbox id = " txtOpinion4 "  runat = " server "  Width = " 100% "  BorderStyle = " None "  Height = " 60px " ></ asp:textbox >  
 6 
 7     // 对特定的控件进行操作
 8     int  i = 1 ;
 9    TextBox t = (TextBox) this .FindControl( " txtOpinion " + sLevNow); 
10    t.Enabled  = true ;
