c# - Remove Items From a CheckBox List -

here main form:

<%@ page language="c#" autoeventwireup="true" codefile="checkdelete.aspx.cs"  inherits="checkdelete" %>   <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org  /tr/xhtml1/dtd/xhtml1-transitional.dtd">    <html xmlns="http://www.w3.org/1999/xhtml">   <head runat="server">   <title></title>  </head> <body> <form id="form1" runat="server"> <asp:checkboxlist id="chkitems" runat="server" style="width: 37px">     <asp:listitem value="a"></asp:listitem>     <asp:listitem value="b"></asp:listitem>     <asp:listitem value="c"></asp:listitem>     <asp:listitem value="d"></asp:listitem>     <asp:listitem value="e"></asp:listitem>     <asp:listitem value="f"></asp:listitem>     <asp:listitem value="h"></asp:listitem> </asp:checkboxlist> <asp:button id="button1" runat="server" onclick="button1_click" text="delete" /> <br /> <br /> </form> 

code in form:

protected void button1_click(object sender, eventargs e) {     (int = 0; < chkitems.items.count; i++)     {         if (chkitems.items[i].selected == true)         {            chkitems.items.removeat(i);         }     }  } 

in form, want delete items user has checked off. however, if select 3 items, @ least 1 item remain on form after user hits delete. missing?

you'll need make list of items want remove , remove them 1 one.

e.g.

list<listitem> toberemoved = new list<listitem>(); for(int i=0; i<chkitems.items.count; i++){     if(chkitems.items[i].selected == true)         toberemoved.add(chkitems.items[i]); }  for(int i=0; i<toberemoved.count; i++){     chkitems.items.remove(toberemoved[i]); } 

in example, remove items go change index of remaining items you've yet loop through. result "missing" items loop through. imagine that's cause of problem.
