c# - Dynamic created radio buttons wont execute event on click -


i have button named "add radio button" in form, , text box named texbox1.

i've written code when click "add radio button", generates radio button; it's own name:

c#:

using system; using system.collections.generic; using system.linq; using system.web; using system.web.ui; using system.web.ui.htmlcontrols; using system.web.ui.webcontrols;  public partial class default2 : system.web.ui.page {     protected void page_load(object sender, eventargs e)     {         if (!ispostback)         {             viewstate["counter"] = 0;         }     }     protected void button1_click(object sender, eventargs e)     {         (int = 0; <= convert.toint32(viewstate["counter"]); i++)         {             htmlgenericcontrol div = new htmlgenericcontrol("div");             radiobutton rb = new radiobutton();             rb.id = i.tostring();             rb.text = "button" + i.tostring();             rb.groupname = "rb";             rb.checkedchanged += radiobutton_checkedchanged;              div.controls.add(rb);             panel1.controls.add(div);         }          viewstate["counter"] = convert.toint32(viewstate["counter"]) + 1;     }     private void radiobutton_checkedchanged(object sender, eventargs e)     {         radiobutton btn = sender radiobutton;         textbox1.text = btn.text;     }  }

asp

<%@ page language="c#" autoeventwireup="true" codefile="default2.aspx.cs" inherits="default2" %>  <!doctype html>  <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server">     <title></title> </head> <body>     <form id="form1" runat="server">     <div>          <asp:panel id="panel1" runat="server">         </asp:panel>         <br />         <asp:textbox id="textbox1" runat="server"></asp:textbox>         <br />         <br />         <asp:button id="button1" runat="server" onclick="button1_click" text="add radiobutton" />      </div>     </form> </body> </html>

the problem after several radio buttons being created, want program work if each of them checked, textbox1.text gets radio button's text string (the name of button) function radiobutton_checkedchanged doesn't execute.

you missed think

rb.checkedchanged +=new eventhandler(rb_checkedchanged);

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
