public partial class MasterPage : System.Web.UI.MasterPage { protected void Page_Load(object sender, EventArgs e) { __________.Text = "欢迎您！"; } } public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { Label labelname = (Label)__________.__________("Label1"); __________.Text = "欢迎" + TextBox1.Text + "！"; } }
举一反三
- protected void Page_Load(object sender, EventArgs e) { if (Request.Cookies["password"] != __________) this.TextBox2.Attributes.Add("value", Request["password"]); } protected void Button1_Click(object sender, EventArgs e) { if (CheckBox1.__________) { Response.Cookies["password"]. __________= TextBox2.Text; Response.Cookies["password"]. __________= DateTime.Now.AddSeconds(20); } }
- .NET框架提供有专门的委托类EventHandler，原型如下： A: public delegate void EventHandler(object sender, EventArgs e); B: public delegate void EventHandler(EventArgs e, object sender); C: public event void EventDelegate(object sender, EventArgs e); D: public event void EventDelegate(EventArgs e, object sender);
- 双击一个名为btnCom的按钮，自动生成的鼠标点击事件处理方法为： A: private void btnCom_Click(object sender, EventArgs e){ } B: public void btnCom_Click(object sender, EventArgs e){ } C: private void btnCom(object sender, EventArgs e){ } D: public void btnCom(object sender, EventArgs e){ }
- protected void Page_Load(object sender, EventArgs e) { Response.Write(Server .__________("<h3>三级标题</h3>")); Response.Write("<__________>"); Response.Write(Server.__________("<h3>三级标题</h3>")); }
- 智慧职教: 阅读下面的程序，按照注释中的要求编写代码。 代码一： public partial class FormTest01 : Form { public FormTest01() { InitializeComponent()； } private void FormTest01_Load(object sender, EventArgs e) { //窗体加载时btnSecond按钮在窗体上消失 _______________________________ } private void btnFirst_Click(object sender, EventArgs e) { //单击btnFirst按钮时btnSecond按钮显示，btnFirst按钮消失 _______________________________ } private void btnSecond_Click(object sender, EventArgs e) { //单击btnSecond按钮时btnSecond按钮消失，btnFirst按钮显示 _______________________________ } }
