1.textBox1.BackColor = System.Drawing.Color.Red
2.TextMode="multiline"时可以取代html中的textarea
3.RadioButton控件中,只需要将GroupName设置为相同就成了RadioButtonlist(该控件的格式:<asp:RadioButtonList ID="radlColors" AutoPostBack="True" OnSelectedIndexChanged="radlColors_SelectedIndexChanged" Runat="Server" > <asp:ListItem text="Red" value="R" /> <asp:ListItem text="Green" value="G" /> <asp:ListItem text="Blue" value="B" /></asp:RadioButtonList>)4.RadioButtonlist数据绑定实例:后台:void Page_Load(Object sender, EventArgs e) { ArrayList colArrayList = new ArrayList(); if (! IsPostBack ) { colArrayList.Add( "Red" ); colArrayList.Add( "Blue" ); colArrayList.Add( "Green" ); radlFavoriteColor.DataSource = colArrayList; radlFavoriteColor.DataBind(); }}前台:<asp:RadioButtonList ID="radlFavoriteColor" Runat="Server"/>
4.RadioButton的两种事件响应方法:1.OnCheckedChanged="City_Changed" (适合搭配属性AutoPostBack="True")
2.最后botton提交OnClick="Button_Click"(投票用这个好!)
5.强制转化类型,例如str转化成long,则long.Parse(strID),一个新闻详细页面总是提示request["id"]类型不一样,一个解决方案如下: private string strID = ""; protected void Page_Load(object sender, EventArgs e) { strID = Request["id"]; GetNews(); }
