c# - What .net data technology is best enabling user def fields via XML in this project -

-

i new asp.net / .net, have designed screens , database structure side project webapp , ready start coding it. needed user defined fields , after deliberation on pros , cons of options decided implement them xml blob.

im looking @ 3 options data access:

1) entity framework: havnt found in on how id go ef

2) dynamic data: create custom field template produces label / textbox pairs, under 1 column header if viewed in (eg gridview)

3) coding dal / bll myself, using sql connections. objectdatasources give enough flexibility in ui hopefully. (i split fields in bll here take it?)

i want stick ms tech, rather nhibernate or such, learning mcts cert (also why im not using mvc need know both it). also, perhaps wrongly, think in using solution no. 3 gaining least relevant experience in terms of employers want. guys think solution newbie skill level here?

edit

once got implementation decided against using xml blobs, opting instead spare fields , meta table.

if goal gain valuable skill employers want code dal / bll yourself.

the wcf data services has blob support. example msdn uses ef might start.

also check out msdn section on ado.net

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...
