c# - Preventing page from refreshing aspx.net -

मेरे पास एक एएसपीएक्स पेज है: 

  & lt;% @ पृष्ठ भाषा = " सी # "कोडबेहिन्ड =" xxxx.aspx.cs "इनहेरिट्स =" xxxx "% & gt; & Lt;; DOCTYPE HTML PUBLIC "- // W3C // डीटीटी एक्सएचटीएमएल 1.0 ट्रांसक्रिप्शन // एन" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> & Lt; html xmlns = "http://www.w3.org/1999/xhtml" & gt; & lt; head id = "head1" runat = "server" & gt; & Lt; title & gt; ड्रॉपडाउनलिस्ट ऑन-चुने गए इंडैक्स परिवर्तित ईवेंट का उपयोग कैसे करें & lt; / title & gt; & Lt; / head & gt; & LT; बॉडी & gt; & Lt; form id = "form1" runat = "server" & gt; & Lt; div & gt; & lt; h2 शैली = "रंग: लाल" & gt; ड्रॉपडाउन सूची: ऑन-चुने गए इंडेक्स बदल गए & lt; / h2 & gt; & Lt; एएसपी: लेबल आईडी = "लेबल 1" रनैट = "सर्वर" फ़ॉन्ट-बोल्ड = "सही" ForeColor = "डोडरब्लू" फ़ॉन्ट-आकार = "बड़ा" & gt; & Lt; / एएसपी: लेबल & gt; & Lt; asp: ड्रॉपडाउन लिस्ट आईडी = "ड्रॉप 1" रनैट = "सर्वर" ऑटोपॉस्टबैक = "सच" ऑन-चुने गए इंडेक्स परिवर्तित = "GetLocationDetails" बैकएंडर = "क्रिमसन" ForeColor = "FloralWhite" onclientselectedindexchanged = "वापसी झूठी;" & Gt; & Lt; / एएसपी: DropDownList & gt; & Lt; / div & gt; & Lt; / प्रपत्र & gt; & Lt; / body & gt; & Lt; / html & gt;   
 ड्रॉपडाउन सूची "drop1" के लिए मान "xxxx.aspx.cs" पृष्ठ से डेटाबेस से आबादी है। जब मैं ड्रॉप डाउन बॉक्स से मान का चयन करता हूं "GetLocationDetails" नामक एक समारोह को aspx.cs से कहा जाता है। जब मैं ड्रॉप डाउन बॉक्स से कोई मान दबाता हूं, तो पृष्ठ ताज़ा होता है और पहला मान केवल चयनित होता है पृष्ठ लोड इवेंट में अपनी ड्रॉपडाउन सूची बाँध:  
   
   
 
 सुरक्षित शून्य पेज_लोड (ऑब्जेक्ट प्रेषक, इवेंटआर्ग्स ई) {if (! (IsPostBack)} {// बाइंड करें या कॉल विधि जो ड्रॉपडाउन सूची से जुड़ती है}}   
  ऑटोपोस्टबैक  सेट है  true  जिससे पूरे पेज को सर्वर पर वापस पोस्ट किया जा सकता है यदि आप  IsPostBack  को  पेज  का ट्रैक नहीं करते हैं तो आपके ड्रॉपडाउनलिस्ट को फिर से बाँध दिया जाता है।

python - Writing Greek in matplotlib labels, titles -

-
Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

-
I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
