如何在另一个事件处理程序方法中访问动态创建的CheckBox事件状态

Question

我已经在button1的click事件中动态创建了一个复选框数组。现在我想在另一个button2点击事件中检查它的checked属性。由于复选框控件是在运行时动态创建的，因此我无法在button2单击事件中访问它。请有人帮我解决这个问题。

public void Display(ref string[] strDmn, ref string[][] strAvblty) 
{ 
    ch = new CheckBox[cntExt/2]; 
    strDomInfo = new string[cntExt/2]; 
    Table t = new Table(); 
    t.Caption = "Domain Availablity"; 
    t.BorderWidth = 1; 
    TableRow tr; 
    TableCell tc; 
    System.Drawing.ColorConverter colConvert = new ColorConverter(); 

    for (int i = 0; i < (strDmn.Length); i++) 
    { 
     for (int l = 0; l < ((strAvblty[i].Length)/2); l++) 
     { 
      tr = new TableRow(); 
      tr.BackColor = (System.Drawing.Color)colConvert.ConvertFromString("#F0E8FF"); 
      for (int j = 0; j < 4; j++) 
      { 
       //string k = strAvblty[i][(i * 2 + 1)]; 
       tc = new TableCell(); 
       tc.Width = 300; 
       switch (j) 
       { 
        case 0: 
         ch[k - 1] = new CheckBox(); 
         strDomInfo[k - 1] = strDmn[i] + "." + strAvblty[i][(l * 2)]; 
         if (strAvblty[i][(l * 2) + 1] == "available") 
         { } 
         else { ch[k - 1].Enabled = false; } 
         tc.Controls.Add(ch[k - 1]); 
         break; 
        case 1: tc.Text = strDmn[i]; 
         break; 
        case 2: tc.Text = strAvblty[i][(l * 2)]; 
         break; 
        case 3: tc.Text = strAvblty[i][(l * 2) + 1]; 
         break; 
       } 
       tr.Cells.Add(tc); 
      } 
      t.Rows.Add(tr); 
     } 
    } 
    // desiredPanel is your panel 
    Panel1.Controls.Add(t); 
} 

protected void btnAdd2Cart_Click(object sender, EventArgs e) 
{ 
    //******I have get the boolen check property here ****** 
} 

Answer 1

你必须创建在Page_Init这些复选框，他们应该在回发重新创建。然后你将能够得到Button2's click handler的值

protected void Page_Init(object sender, EventArgs e) 
{ 
// Create here 
}
