asp.net - UpdatePanel + Validators works! Stops async requests for sometime after validation tho -

-

this not same old question validators , update panel compatibility.

here's scenario:

i have aspx page script manager. page has ascx user control functionality. in control, have few panels , areas enabled/disabled or visible/hidden according visitor selects clicking on of radio buttons control behaviour. fine until point. validators , updatepanel not fighting against each other, however, if try submit page without filling form, validation message on summary , it's validation itself.. here's problem, radio buttons, responsible set visibility areas stops working, starts working again after 2nd or 3rd click. it's not delay or anything.. seems handlers not bound control, click again, , cleans summary , error notifications , starts working again.. don't know if adds issue, both user control , page have telerik controls such combo box load on demand, tooltips , loading panel..

i have searched lot , find question regarding validation controls not working inside updatepanel or updatepanel not working validators.. in case, works, have problems after validation has been performed , page.isvalid set false..

to me sounds there server error in first request ajax sending. here recommendation:

open web page in firefox, open firebog , select "network" tab. tab shows every single request browser sends server (including request scripts, images, ... , ajax async requests).

so clear list under "network" in firebog , trigger ajax first time, see if there request sent server. if there can see if response ok 200 response or 500 server error , ofcourse can see full details of error.

hope helps.

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...
