c# - jQuery Calling an ASMX Web Service that Returns Data -

-

i using jstree organize pages created users. upon right-clicking , pressing "rename" want fire js function hits function in code behind without post (if possible). want grab whichever item's i'm on id , rename in database , update jstree.

here sample code-behind function:

[system.web.services.webmethod] protected void renamepage(object sender, eventargs e) {     datatable dt = new datatable();     using (sqlconnection con = new sqlconnection(global.constring))     {         con.open();         using (sqlcommand cmd = new sqlcommand("contentpageupdate", con))         {             cmd.parameters.add("@title", sqldbtype.varchar).value = global.safesqlliteral(txtpage.text, 1);             cmd.commandtype = commandtype.storedprocedure;             cmd.executenonquery();         }         con.close();          //update content page repeater         using (sqlcommand cmd = new sqlcommand("contentpagegetall", con))         {             using (sqldataadapter da = new sqldataadapter(cmd))             {                 da.fill(dt);             }         }     } }

don't think of jquery hitting c# functions, rather jquery hitting resource identified uri.

when make ajax request jquery, give url of destination , standard httprequest url. can page (webforms) or controller action (mvc).

since looks you're using webforms, make new page handle request. if put breakpoint in page_load method you'll see gets fired when invoke ajax method:

in javascript right click can use jquery's ajax method so:

$.ajax('mypage.aspx');

in mypage.aspx:

public void page_load(object sender, eventargs e) {     response.write("you called me!"); }

you can response written adding few arguments $.ajax call:

$.ajax('mypage.aspx', { success: function(data, textstatus, jqxhr) {     alert(data); }});

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
