  • How can I bind dynamic data to DataGridTemplateColun in code?

    - by TuomoT
    I'm using DataGrid from CodePlex. I have objects (ICustomTypeDescriptor) that have properties 'name' 'description' 'c' 'd' and so on (the names are dynamic, and so is the value) and they have information behind them. I have templates for different types. And if I have to list the properties of a single element I can just bind to the values in xaml and use datatemplateselector (in datagridtemplatecolumn) which will pick the correct template. However, when I'm listing several of the elements, how can I use the selectors and the templates? How do I get the correct property bound to the template (two-way)? When ignoring the need for different templates, using DataGridTextColumn with bindings is very simple (and works, see example below), is there any way to use similar approach with the DataGridTemplateColumn? foreach (String propertyName in listOfPropertyNames) { DataGridTextColumn textColumn = new DataGridTextColumn() { Header = propertyName, Binding = new Binding() { Path = new PropertyPath(propertyName) } }; DataGrid.Columns.Add(textColumn); }

  • How to respond to any kind of interruption?

    - by mystify
    My app is playing a pretty complex animation. It's like a flipbook. What I do is: I have a huge loop with selectors, and after every delayed call the next one is called. Now someone calls the user and the device suddenly shows up this fat green status bar and maybe some big pick-up-the-phone-call overlay. Or: The alarm clock rings, and a big alert sheet appears in front of just about everything. It would be great to just pause the whole animation in case of ANY interruption. Probably I've also missed like 5 more possible interruptions. How are you doing that? How do you get notified for all interruptions and then call one single -stopEverything method?

  • jQuery wildcard selection

    - by Yuval A
    Suppose you have some <div>s: <div id="div_num1"></div> <div id="div_num2"></div> <div id="div_num3"></div> You can select all those divs by choosing $("div[id^='div_num']"). How can you buld a function that references the number succeeding the prefix? For example, a function which will alert the number 3 for "div_num3". More generally, how can you use full-blown regex in jQuery selectors?

  • Dash surrounding text

    - by Brandon Hansen
    Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

  • What are the likely main reasons my website is very slow on IE?

    - by Bhupi
    Hi, I need to know what can be the main reasons (apart from the basics like grouping CSS selectors, reducing image size, using image sprite etc.) which makes a website slow on Internet Explorer, because my website works fine on the others like FF, chrome etc. Is it the huge use of Javascript framework (ie. jQuery, extjs, prototype)? Is it because of the use of plugins based on JS framework? Should I use core javascript and remove the use of any js framework? Should I try to avoid using jQuery(document).ready()? in case of jQuery framework? Above some of the questions which I know and please answer the questions which I couldn't ask because of lesser knowledge about these. I need to make my website perform well on IE (6,7,8) also please suggest. Thanks

  • Do I have to duplicate this function? - jQuery

    - by Josh
    I'm using this function to create an transparent overlay of information over the current div for a web-based mobile app. Background: using jQTouch, so I have separate divs, not individual pages loading new. $(document).ready(function() { $('.infoBtn').click(function() { $('#overlay').toggleFade(400); return false; }); }); Understanding that JS will run sequentially when i click the button on the first div the function works fine. When I go to the next div if I click the same button nothing "happens" when this div is displayed, but if i go back to the first div it has actually triggered it on this page. So I logically duplicated the function and changed the CSS selector names and it works for both. But do I have to do this for each use? Is there a way to use the same selectors, but load the different content in each variation?

  • Using custom HTML attributes for JavaScript purposes?

    - by user1103990
    One of my colleagues doesn't like to use HTML classes and ids for javascript/jQuery purpose. Therefore I've seen that he had created custom html attribute such as <div id="myid" class="cssClasses ..." [some-purpose-id]="mycustomId">...</div> I asked him if it was really a good idea and he replied that he considers that classes and Ids should be reserved for styling. Personally, I would have used classes. Some classes would have been used for styling, and some other classes would have been used for programming (jQuery selectors). The idea is to keep things appart also. And of course jQuery could set styling classes but if possible not use them for selection. Of course I also use id when appropriate but since an id is unique on a page, I like to do generic stuff using classes. I would like to know you opinions on the better approach (if there is one). Thank you.

I wrote selectors for both buttons.; But, I could not differentiate the buttons for each cell. How do I know which cell button was touched. What to do, to know that a particular cell's button was touched ? Thank you.

  • load data from external file jQuery

    - by bah
    Hi, I need to take data from external file and format it, the problem is, i want to have that data stored into a variable. Load method works for me, because i need to load not the whole document, but just a part of it, but then again, i want to load to variable and not to some dom element. $.get can do this, but it doesn't support selectors. Is there any way I could make this? Now examples: Mine external file consists of a table, which has format like this: <table><tr><td><img /></td></tr><tr><td><a></a></td><td><span></span></td></tr></table> I need to extract img, a and span tags because I need them to be displayed in different order than they're now. So, is there any chance for me that i could make this work? Thanks.

  • iPhone/iPad fatal error in C++ code produces no output in the log

    - by morgancodes
    I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

  • Raphael how to get last path and last circle, if i have 2 elements in the paper?

    - by 3gwebtrain
    I need to find the last path or circle in a paper, in order to perform further calculations to draw more elements, and calling 'paper.bottom' only gets the last element. Is there any way to get shapes of specific types, e.g. bottom.path, bottom.circle or traverse for the n'th child? I want to avoid using jQuery selectors, as i can't retrieve any properties from those. An example of a paper populated with shapes: var paper = Raphael('paper',500,500); var c1 = paper.circle(100,100,50) var p1 = paper.path("M10 20l70 0") var c2 = paper.circle(200,100,50)

  • Patterns for avoiding jQuery silent fails

    - by Matias
    Is there any good practice to avoid your jQuery code silently fail? For example: $('.this #is:my(complexSelector)').doSomething(); I know that every time this line get executed, the selector is intended to match at least one element, or certain amount of elements. Is there any standard or good way to validate that? I thought about something like this: var $matchedElements = $('.this #is:my(complexSelector)'); if ($matchedElements.length < 0) throw 'No matched elements'; $matchedElements.doSomething(); Also I think unit testing would be a valid option instead of messing the code. My question may be silly, but I wonder whether there is a better option than the things that I'm currently doing or not. Also, maybe I'm in the wrong way checking if any element match my selector. However, as the page continues growing, the selectors could stop matching some elements and pieces of functionality could stop working inadvertently.

  • Seek a jQuery-based inplace HTML editor

    I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings.

Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx

  • an array of strings as a jQuery selector?

    - by dalbaeb
    I have an array of strings that are valid jQuery selectors (i.e. IDs of elements on the page): ["#p1", "#p2", "#p3", "#p4", "#p5"] I want to select elements with those IDs into a jQuery array. This is probably elementary, but I can't find anything online. I could have a for-loop which creates a string "#p1,#p2,#p3,#p4,#p5" which could then be passed to jQuery as a single selector, but isn't there another way? Isn't there a way to pass an array of strings as a selector? EDIT: Actually, there is an answer out there already.

  • What is the REGEX of a CSS selector

    - by user421563
    I'd like to parce a CSS file and add before every CSS selector another selector. From: p{margin:0 0 10px;} .lead{margin-bottom:20px;font-size:21px;font-weight:200;line-height:30px;} I'd like: .mySelector p{margin:0 0 10px;} .mySelector .lead{margin-bottom:20px;font-size:21px;font-weight:200;line-height:30px;} But my CSS file is really complex (in fact it is the bootstrap css file) so the regex should match all CSS selectors. For now I have this regex: ([^\r\n,{};]+)(,|{) and you can see the result here http://regexr.com?328ps but as you can see there are a lot of matches that shouldn't match for example: text-shadow:0 -1px 0 rgba(0, matchs positive but it shouldn't Does someone have a solution ?

  • Can we use (id) in if- else condition ?

Should not we use (id) in if condition ? I want to get called two selectors by using the if- else condition. How can I make it ? Thank You.

  • Pulling .live() functionality out of jQuery

    - by Daniel
    I am writing a Firefox Add-On that currently is depending on jQuery for the following things: Selectors Animations A special .live("focus") hail-mary event-catching maneuver that happens to work with jQuery 1.4.2 (but not 1.4.4) jQuery isn't well suited for functioning inside XUL, and it's a miracle we've gotten this far with it. We're trying to remove the jQuery requirements, the first two are easy (animations are simple, and we can use .querySelector() instead of jQuery), but the .live has proven impossible to do on our own. I've tried reading the source code, but I haven't been able to piece it apart. What is the jQuery .live function doing? There's clearly a lot more going on than document.addEventListener("focus"/"focusin",function_to_pick_apart_events). What else is going on here?

  • How to have a javascript callback executed after an update panel postback?

    - by TNunes
    I'm using a jQuery tip plugin to show help tips when the user hovers certain elements of the page. I need to register the plugin events after the page is loaded using css selectors. The problem is I'm using an ASP.NET Update Panel and after the first postback, the tips stop working because the update panel replaces the page content but doesn't rebind the javascript events. I need a way to execute a javascript callback after the Update Panel refreshes its content, so I can rebind the javascript events to have the tips working again. Is there any way to do this?

  • Using dd-wrt Dynamic DNS client with CloudFlare

  • AWS Cloud Formation.Requires capabilities : [CAPABILITY_IAM] (Child Stack)

    - by Drew Khoury
    I'm running a CloudFormation template in the AWS Console. Running Stack Directly I started with a template that used IAM resources, and the console prompts me to acknowledge IAM capabilities when running the stack directly. Running Stack as a child I then tried to call the same stack from a parent stack and did not receive the same prompt. The stack then failed with the message: Requires capabilities : [CAPABILITY_IAM] Research The docs indicate that I can run CF scripts in a number of ways. There's plenty of docs around CLI/API and supplying the capability parameter, but there appears to be no information about how to make sure it's applied when running through the console. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html IAM Resources in AWS CloudFormation Templates CF Console CLI API What I've done / What I think I've raised an issue via the forum for now, but no response (yet): https://forums.aws.amazon.com/thread.jspa?threadID=139160 I suspect this is a bug in the Console, as there doesn't appear to be any documentation of how to change the behaviour via the console and as far as I'm aware this should just work. Anyone came across the same problem, or can report that it's working fine for them?

  • Exchange 2010 add mailbox server to DAG error

    - by Michael
    Hello, i'm having some problems when adding a second mailbox server to my DAG in Exchange 2010. The test setup goes like this: 1x windows server 2008 (DC/DNS) 2x windows server 2008 (Exchange 2010) I have made sure all services are up and running and that the "Exchange Trusted Subsystem" account is set as a local admin. When i create a DAG i can add the first mailbox server (A) without any problems, but when i go to add the second (B) it gives me an error saying "Unable to contact the Cluster service on 1 other members (member) of the Database availability group. It does the same if i add (B) first and then try to add (A).

  • certutil -ping fails with 30 seconds timeout - what to do?

    - by mark
    The certificate store on my Win7 box is constantly hanging. Observe: C:\1.cmd C:\certutil -? | findstr /i ping -ping -- Ping Active Directory Certificate Services Request interface -pingadmin -- Ping Active Directory Certificate Services Admin interface C:\set PROMPT=$P($t)$G C:\(13:04:28.57)certutil -ping CertUtil: -ping command FAILED: 0x80070002 (WIN32: 2) CertUtil: The system cannot find the file specified.

C:\(13:05:28.79)set PROMPT=$P$G C:\ Explanations: The first command shows you that there are –ping and –pingadmin parameters to certutil Trying any ping parameter fails with 30 seconds timeout (the current time is seen in the prompt) This is a serious problem. It screws all the secure communication in my app. If anyone knows how this can be fixed - please share. Thanks. P.S. 1.cmd is simply a batch of these commands: certutil -? | findstr /i ping set PROMPT=$P($t)$G certutil -ping certutil -pingadmin set PROMPT=$P$G EDIT1 I have succeeded to pin down the single windows API that causes the problem - DsGetDcName According to the windbg, the certutil -ping invokes it like so: PDOMAIN_CONTROLLER_INFO pdci; DWORD ret = ::DsGetDcName(NULL, NULL, NULL, NULL, DS_DIRECTORY_SERVICE_PREFERRED, &pdci); On my workstation it times out for 30 seconds and then returns error code 1355, which is ERROR_NO_SUCH_DOMAIN No domain controller is available for the specified domain or the domain does not exist. On another machine, which is accidentally a windows server 2003, it returns almost immediately with the correct domain controller name inside the returned DOMAIN_CONTROLLER_INFO structure. Now the question is what is missing on my workstation for that API to find the correct domain controller?
