C#2008与.NET 3.5 高级程序设计读书笔记(32) ASP.NET Web控件、主题和母版页

1.System.Web.UI.Control类型

遍历控件

string theInfo = String.Empty;
    theInfo = string.Format("Has controls? {0} <br/>", myPanel.HasControls());
    foreach (Control c in myPanel.Controls)
    {
      if (!object.ReferenceEquals(c.GetType(), typeof(System.Web.UI.LiteralControl)))
      {
        theInfo += "***************************<br/>";
        theInfo += string.Format("Control Name? {0} <br/>", c.ToString());
        theInfo += string.Format("ID? {0} <br>", c.ID);
        theInfo += string.Format("Control Visible? {0} <br/>", c.Visible);
        theInfo += string.Format("ViewState? {0} <br/>", c.EnableViewState);
      }
    }
    lblControlInfo.Text = theInfo;

动态添加控件

    for (int i = 0; i < 3; i++)
    {
      // Assign a name so we can get
      // the text value out later
      // using the incoming form data.
      TextBox t = new TextBox();
      t.ID = string.Format("newTextBox{0}", i);
      myPanel.Controls.Add(t);
    }
