c# - 动态控制无法正常工作

Question

问题:我有动态控制，我将把它放到 pnlGetValues 单击按钮后，我无法在循环中找到它。

string _name = Regex.Replace(_response.Name, @"\s+", "");
_dynamicTextbox.ID = "txtID";
_response.Required.ToString();
_dynamicTextbox.AutoPostBack = false;
_dynamicLabel.Text += "" + "<br><br>";
pnlGetValues.Controls.Add(_dynamicTextbox);
pnlGetValues.Controls.Add(_dynamicLabel);

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
        foreach (Control _control in pnlGetValues.Controls)
        {
            pnlGetValues.Controls.Count.ToString();
            if (_control is TextBox)
            {
                TextBox _value = (TextBox)_control.Findcontrol("txtID");
            }
        }
    }

Answer 1

试试这段代码:

if (_control is TextBox)
        {
            TextBox _value = (TextBox)_pnlGetValues.Findcontrol("txtID");
        }
