and here codebehind cs file

using system; using system.configuration; using system.data; using system.linq; using system.web; using system.web.security; using system.web.ui; using system.web.ui.htmlcontrols; using system.web.ui.webcontrols; using system.web.ui.webcontrols.webparts; using system.data.sqlclient; using system.collections;  public partial class _default : system.web.ui.page {       dataview todo = new dataview();      protected void page_load(object sender, eventargs e)     {          if (calendar1.selecteddate == datetime.minvalue)             calendar1.selecteddate = calendar1.todaysdate;     }       void page_prerender()     {         todo = (dataview)calendarsrc.select(datasourceselectarguments.empty);         todo.sort = "date";       }      protected void calendar1_dayrender(object sender, dayrendereventargs e)     {         if (todo.findrows(e.day.date).length > 0)             e.cell.backcolor = system.drawing.color.aqua;      }      protected void calendar1_selectionchanged(object sender, eventargs e)     {         formview1.changemode(formviewmode.edit);      }      protected void butaddnew_click(object sender, eventargs e)     {         formview1.changemode(formviewmode.insert);       }   }

do want text directly in cell of target day?

use ondayrender method have add literal control:

protected void calendar1_dayrender(object sender, dayrendereventargs e) {     if (todo.findrows(e.day.date).length > 0)         e.cell.backcolor = system.drawing.color.aqua;      if (e.day.date.day == 18)         e.cell.controls.add(new literalcontrol("<br />test show on calendar.")); }

good luck,

patrick

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.

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...
