जब मैं कोशिश करता हूँ: 

  $ (MyGrid) .jqGrid ('getGridParam');  
 यहां छवि विवरण दर्ज करें

 ग्रिड का पैडमीटर  डेटा  होल्ड  स्थानीय  डेटा। यदि आप  रिमोट स्रोत  ( डेटाटाइप: "जेसन"  या  डेटाटाइप: "xml" ) का उपयोग करते हैं, तो यह (खाली सरणी से) खाली नहीं होगा  loadonce: true  विकल्प मामले में jqGrid बस सर्वर से लौटाए गए डेटा के  पेज  के साथ ग्रिड (HTML तालिका) भरें। मामले में सर्वर केवल डेटा को पकड़ता है और यह सॉर्टिंग, पेजिंग और फ़िल्टरिंग / डेटा की खोज के लिए ज़िम्मेदार है।  
 यदि आपके पास कोई बड़ी डाटासेट नहीं है (कम से कम 1 लाख या कम 10000 पंक्तियों के रूप में) एक का बेहतर प्रदर्शन आमतौर पर  loadonce: true  विकल्प के उपयोग से होता है मामले में सर्वर केवल  सभी  आइटम के साथ सॉर्ट किए गए डेटा वापस कर सकता है JqGrid इस तरह के डेटा का पहला पृष्ठ प्रदर्शित करेगा और  डेटा  और  _index  पैरामीटर में सर्वर से लौटा  सभी  डेटा धारण करेगा। पहली लोडिंग के बाद jqGrid  डेटाटाइप  को  "स्थानीय"  में बदलता है और बाद में सॉर्टिंग, पेजिंग और डेटा की खोज / फ़िल्टरिंग सर्वर से कोई भी संचार किए बिना किया जाएगा।

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...
