c# - Show query values in a form of list using li tag -


i have following c# code: 

try {     conn.open();     string sql = "my query returns n rows";      oraclecommand cmd = new oraclecommand(sql, conn);     cmd.commandtype = commandtype.text;      oracledatareader dr = cmd.executereader();      while (dr.read())      {         mylistbox.items.add(dr.getstring(0));     } } catch (exception ex) {     label1.text = "## error: " + ex.message; }

on .aspx page, instead of using listbox, want each value in list item using li tag. i've been searching can't find if it's possible using loop , if it's possible, don't have idea on how .

note: honestly, requirement, need use li tag this.

option 1:

better way user datarepeater control.

somewhere have class:

class item {     public string description { get; set; }      item(string description)     {         this.description = description;     } }

here prepare list of objects(item):

list<item> items  = new list<item>(); while (dr.read())  {     items.add(new item(dr.getstring(0))); }  repeater1.datasource = items; repeater1.databind();

and here datarepeater code:

<ul> <asp:repeater runat="server" id="repeater1">    <itemtemplate>        <li>'<%# eval("description") %>'</li>    </itemtemplate> </asp:repeater> </ul>

option 2:

you can prepare custom html , assign control display.

change while loop:

while (dr.read())  {     mylistbox.items.add(dr.getstring(0)); }

to this:

string html = "<ul>"; while (dr.read())  {     html += "<li>" + dr.getstring(0) + "</li>"; } html += "</ul>";  divlist.innerhtml = html;

where divlist regular div can place on .aspx page , add attribute runat="server".

<div id="divlist" runat="server"></div>

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
