c# - Sitecore sorting by created date issue -


i having trouble figuring out how can sort list of items in descending order according created date (i know sitecore allows sorting items in ascending order created date). i'm still pretty new sitecore, i'm not sure do...any suggestions helpful!

 item[] blogposts = homeitem.axes.selectitems(@"child::*[@@templatename='blogcomment']");              if (blogposts != null)             {                  dataset ds = new dataset();                 datatable posts = ds.tables.add("posts");                  posts.columns.add("postname", type.gettype("system.string"));                 posts.columns.add("datecreated", type.gettype("system.string"));                 posts.columns.add("postcomment", type.gettype("system.string"));                  foreach(item postitem in blogposts)                 {                     datarow dr = posts.newrow();                      dr["postname"] = postitem.fields["name"].value;                     dr["datecreated"] = postitem.statistics.created;                     dr["postcomment"] = postitem.fields["comment"].value;                      posts.rows.add(dr);                 }                 commentslistrptr.datasource = ds;//this repeater i'm using show data                 commentslistrptr.datamember = "posts";                 commentslistrptr.databind();             }

you can sort items using linq:

var items = sitecore.context.database.selectitems("/sitecore/content/home/*"); items = items.orderby(x => x[sitecore.fieldids.created]).reverse();

obviously change query or item list fit requirements.

edit following addition of code:

set repeater in ascx, we'll use sitecore fieldrenderer disable webediting in control:

<asp:repeater id="rptblogposts" runat="server" onitemdatabound="rptblogposts_itemdatabound">     <headertemplate><table></headertemplate>     <itemtemplate>         <tr>             <td><sc:fieldrenderer runat="server" id="postname" fieldname="name" disablewebediting="true" /></td>             <td><asp:literal runat="server" id="postdate"></asp:literal></td>             <td><sc:fieldrenderer runat="server" id="postcomment" fieldname="comment" disablewebediting="true" /></td>         </tr>     </itemtemplate>     <footertemplate></table></footertemplate> </asp:repeater>

and in code behind on page_load bind control, bind datasource of repeater , set fieldrenderer item , display created date in format suit.

private void page_load(object sender, eventargs e) {     item[] blogposts = homeitem.axes.selectitems(@"child::*[@@templatename='blogcomment']");     if (blogposts.any())     {         rptblogposts.datasource = blogposts.orderby(x => x[sitecore.fieldids.created]).reverse();         rptblogposts.databind();     } }  protected void rptblogposts_itemdatabound(object sender, repeateritemeventargs e) {     if (e.item.itemtype == listitemtype.item || e.item.itemtype == listitemtype.alternatingitem)     {         var currentitem = e.item.dataitem item;         var scpostname = e.item.findcontrol("postname") fieldrenderer;         var litpostdate = e.item.findcontrol("postdate") literal;         var scpostcomment = e.item.findcontrol("postcomment") fieldrenderer;          scpostname.item = currentitem;         litpostdate.text = currentitem.statistics.created.tostring("h:mm:ss mm/dd/yy");         scpostcomment.item = currentitem;     } }

your sitecore query can expensive performance wise depending on how content have how deep content tree is, i'm not sure version of sitecore using, in case index content (with lucene) , use retrieve posts. if using sitecore 7 take @ post linq sitecore

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
