Question

我在button1点击事件中动态创建了一个复选框数组。现在我想在另一个button2点击事件中检查其已检查的属性。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 ******
}

您必须在Page_Init中创建这些复选框，并且应在回发时重新创建这些复选框。然后，您将能够获得Button2's click handler

中的值

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

如何在另一个eventhandler方法中访问动态创建的CheckBox事件状态
