rendering

问题 I know how to do this in MVC: <title> <%= Model.Title %> </title> I also know how to bind a SQLDataSource or ObjectDataSource to a control on a form or listview. But how do I render a field from my SQLDataSource or ObjectDataSource directly into the HTML? 回答1: You can declare a property and set its value using your desired field's value. Code-behind: private string myTitle; protected string MyTitle { get { return myTitle; } set { myTitle = value; } } protected void Page_Load(object sender,

问题 In order to not repeat myself, I would like to create a function that render a form block (text field or text area) in a specific way. I want a result like this one (using Haml, and twitter-bootstrap): .form-block.input-prepend %span.add-on> %i.icon.icon-home = f.text_field :name, :value => @store.name, :placeholder => 'Company Name' To do that, I created a file views/layouts/_form-block.html.haml where I inserted the following code: .form-block.input-prepend %span.add-on> %i{ :class => "icon

问题 I have created a Ext.Panel object, it rendered properly to specified div element on my page. I want to replace the panel object underlying element(previously rendered div element) to another div which will be identified dynamically. Here I don't want to create the Panel object once again by specifying identified div element, I need to make use of existing panel object and need to show the panel in the place where the identified div exists. Can any one helps me regarding this. Thanks Venkat

问题 I would like to build somthing like the chart in the sample: barLineAnimated.html. my problem is; i have more then 1 series, which i like to render as bars, and one should be rendered as line. I can't undestand the sample: one the 2 series in the sample will be rendered in different way. How can i set the kind of rendering for the single series? 回答1: Try this inside the jqplot constructor: seriesDefaults : { renderer: $.jqplot.BarRenderer, rendererOptions : { barWidth: 30 } }, series : [{}, {

问题 I'm making a 2d game, where blocks are falling down ( tetris style). I need to render alphabets on these blocks. This is how I am creating blocks: var geometry = new THREE.BoxGeometry( this.BLOCK_WIDTH, this.BLOCK_WIDTH, 4 ); var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); this.blocks = []; for (var i = 0; i < rows * columns; i++) { cube = new THREE.Mesh( geometry, material ); cube.visible = false; cube.letter = letterGenerator.getNextLetter(); this.blocks[i] = cube; scene

问题 Here is very simple code .. Only thing is I repeated same code manytimes for detail debug. Detail info: OpenGL version 3.3.0, Window 7 OS and VS2008, OpenCV 2.2.0. RenderObject(); //glPushClientAttrib(GL_CLIENT_ALL_ATTRIB_BITS); Mat image; image.create(screenHeight,screenWidth, CV_8UC3); glReadPixels(0, 0, screenWidth, screenHeight, GL_BGR, GL_UNSIGNED_BYTE, (uchar*)image.data); int error_code1 = glGetError(); // Error Code: 0, NO Error, Also output is good/as expected! glBindFramebufferEXT

问题 Can somebody please explain why rendering with premultiplied alpha (and corrected blending function) looks differently than "normal" alpha when, mathematically speaking, those are the same? I've looked into this post for understanding of premultiplied alpha: http://blogs.msdn.com/b/shawnhar/archive/2009/11/06/premultiplied-alpha.aspx The author also said that the end computation is the same: "Look at the blend equations for conventional vs. premultiplied alpha. If you substitute this color

问题 ok here is my issue... user habtm groups(roles) i have views for admins, boardmembers, managers, and vps. so when an user have just one role the app reads the role and we're going fine... BUT when he/she/it have two or more roles it just take the first one and dissmiss the others... the questions how should i manage those role so the user can choose what view to see? should i tell the user what role he wants to play after login? Ex: made him decide (want's to play admin, want's to play

问题 I use LWJGL to render everything in my game I am making, and I use it to render backgrounds, which is okay, but when I render things less than the full size of the display, it shows random lines and the image is slanted. Here is a screenshot picture; See the split line about a third of the way across, and the line on the left hand side. http://i.stack.imgur.com/6O9dI.png And here is my code; ImageLoader.STAT_BAR.bind(); GL11.glBegin(GL11.GL_QUADS); GL11.glTexCoord2f(0,0); //TOP LEFT GL11

问题 Is there a way to get notified (e.g., by an event) when a Visual has been (re-)rendered? Basically, I would like to take a screen shot whenever a Visual's appearance has changed. I assume the rendering thread is taking care of this in the background. I am trying to avoid grabbing a screen shot periodically since I am only interested in changes (e.g., hovering the cursor over a button would change its appearance). Any hint is highly appreciated! 回答1: The best way I've found is to add an empty
