  • Can't access UI from a delegate?

    - by Nick Brooks
    I got this code: GrooveOnDownload *dlg = [[GrooveOnDownload alloc] init]; NSURLDownload *dw = [[NSURLDownload alloc] initWithRequest:request delegate:dlg]; It starts the download in a delegate class with outlets for UI controls. But for some reason controls don't respond to direct messages from the delegate. //Header of the delegate @interface GrooveOnDownload : NSObject { IBOutlet id downloadButton; //... //Implementation //... [downloadButton setEnabled:FALSE]; // Doesn't work //... Any ideas?

  • Coloring Default Buttons - color filter only on unfocused state

    - by rlo
    I want to buttons of different colors, but I want to do so while using the default button background resource in order to preserve the onfocus and onclick states. This is because I want to use the default highlight color of the OS for my app, which is NOT always orange (HTC Sense makes it green). I found that adding a color filter to the button's background drawable works great (in this case, blue): myButton.getBackground().setColorFilter(Color.parseColor(this.getString (R.color.button_blue)), Mode.MULTIPLY); BUT, when the button is focused or clicked, it turns a nasty orange_blue because it mixes the color filter with the orange of the background drawable. I want to ONLY set this color filter for the unfocused/unclicked nine- patch drawable within the default button's statelistdrawable. I'm not sure how else to do this. I see a similar solution here: http://stackoverflow.com/questions/2065430/fixed-android-detecting-fo... but I have some concerns with that solution, mainly what if the OS changes the graphic of the default button? Since the normal unfocused/ unpressed graphic is now hardcoded into the app, it would break the flow. Maybe can someone comment on whether it would be good or bad practice to hardcode the default graphic into the app? What are the chances of the OS completely changing the graphic? Any help please? Thanks very much!!

  • Best way to do client/server validation in ASP.NET in 2010?

    - by punkouter
    First there was the ASP.NET validators and we used them... Then some people on the team did things manually in javascript... Then a bunch of jquery validation libraries came out... Then MVC2 came out with attributes as validators.. I work with apps that have alot of forms with alot of various validation (Some fields needs to be compared with other values in a DB so a postball/ajax call is required) .. Right now I have a mess of ASP.NET custom validators and functions that calculate on the server side as well. Can I get some opinions on the best tool/combination to approach this job that can create the smallest/most elegant code? Pure server side solution? AJAX/Jquery? A certain plugin for jquery? For example, I have 2 dates.. I want to make sure that the 1st date is less than the 2nd date... Are there jquery validators that encapsulate this? My feeling is if I can get jquery plugins to handle half the more basic validation for my that could cut my code in half.

    - by paul
    I have a hidden DIV which contains a toolbar-like menu. I have a number of DIVs which are enabled to show the menu DIV when the mouse hovers over them. Is there a built-in function which will move the menu DIV to the top right of the active (mouse hover) DIV? I'm looking for something like $(menu).position("topright", targetEl);

    Hello, I was making a small thing in HTML and basically I have some "frames" like <div id="frame_1"> ... </div> <div id="frame_2"> ... </div> ... Basically what I want is for only one frame to be visible at one time and to navigate between frames easily with previous and next buttons (navigation by frame number a plus, but not required) Before I set out to write it myself I figured someone had already done it so has it been done?

  • Jquery .html replacer just empties my selector, what's wrong!?

    - by jphenow
    $("#autoNames").html(function (index, html) { var begin = "<script language='javascript' type='text/javascript'> var names = ["; var end = String('];' + '<' + '/' + 'script' + '>'); var result = begin.concat(jsonService, end); $("#autoNames").html(result); return false; }); I can't figure out for the life of me why this doesn't work. I've gotten the html function to work before, but for some reason this just leaves my autoNames tag empty... and i've called an alert() on the result variable and things exist in that string... any clues?

  • How can I refresh a page via jQuery and ensure that there's a connection?

    - by Steve
    Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later. I'm using the jQueryTimers plugin. this is my code so far: //reload trigger $(document).everyTime('60s', 'pagerefresh', reloadPage, 0, true); //refresh function function reloadPage() { $.ajax({ url:'index-1.php', type:'HEAD', success: location.reload(true) }) } I have no idea how to tell jQ what I want. any hint appreciated.

  • Error message: "$(window).width is not a function"

    - by Crippletoe
    Hi all, i am trying to use a jQuery scrollbar called "Jscrollhorizontalpane". when i am trying to use it i get the following error message: "$(window).width is not a function" in firebug's console. i am new to jQuery do this might be very basic but still, i dont know what that means and why there is a problem. the scroller comes in a bundle with a few files, one of which is called "jScrollHorizontalPane.js" and i believe it holds the code for the scroller. i tried replacing $ signs there with the word "jQuery" (in case there is a conflict) but it didnt seem to help. also important to add that on the same page i am using another jQuery scroller (a vertical one as opposed to the horizontal on mentioned above) which works just fine and when i examined it's .js file, i could spot lines with "$(window).width". any ideas?

  • best method in jquery for replacing rows in a table after server side processing such as mysql sorti

    - by Kevin J
    What is the 'best practice' when returning dynamic data for a table (server side sorting, filtering etc from a db) ? Do you return just the data in json, and repeatedly clone a row element, replacing the values in each row (thus decreasing the size of the ajax call, but increasing the client side processing), or return the full html, and replace with .html or .append? Or is there another method I'm missing? This is a frequent situation in my app, and in some cases a bottleneck, and I am unsure if what I am doing is the best solution. Currently, I return the row html and use a single .append call, after emptying all the rows except the header.

  • JQUERY - how to get updated value after ajax removes data from within it?

    - by Brian
    I have a an element with thumbnails. I allow users to sort their display order (which fires off an update to the DB via ajax). I also allow them to delete images (which, after deletion, fires off a request to update the display order for all remaining images). My problem is with binding or live I think, but I don't know where to apply it. The array fired off upon delete contains ALL the ids for the images that were there on page load. The issue is that after they delete an image the array STILL contains the original ids (including the one that was deleted) so it is obviously not refreshing the value of the element after ajax has removed things from inside it. I need to tell it to go get the refreshed contents... From what I have been reading, this is normal but I don't understand how to tie it into my routine. I need to trigger the mass re-ordering after any deletion. Any ideas gurus? $('a.delimg').click(function(){ var parent = $(this).parent().parent(); var id = $(this).attr('id'); $.ajax({ type: "POST", url: "../updateImages.php", data: "action=delete&id=" + id, beforeSend: function() { parent.animate({'backgroundColor':'#fb6c6c'},300); $.jnotify("<strong>Deleting This Image & Updating The Image Order</strong>", 5000); }, success: function(data) { parent.slideUp(300,function() { parent.remove(); $("#images ul").sortable(function() { //NEEDS TO GET THE UPDATED CONTENT var order = $(this).sortable("serialize") + '&action=updateRecordsListings'; $.post("../updateImages.php", order, function(theResponse){ $.jnotify("<strong>" + theResponse + "</strong>", 2000); }); }); }); } }); return false; }); Thanks for any help you can be.

  • InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

    - by marcinn
    The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)
