Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • a5_AJAX_window()

    Can you make a floating window by using the a5_AJAX_Callback(), with something like this on the callback page? My calling page has a <div> with ID="StatusContainer". This is a starting point, but nothing's happening.

    Code:
    <%A5
    ' Callback Page script:
    DetailViewFloatingWindow()
    
    function DetailViewFloatingWindow as c (vars as p)
    with vars 
    
    DetailViewFloatingWindow = <<%txt%
    	StatusContainer_FLOATING_WINDOW = new a5_AJAX_window({
    			title: {
    				html: 'Detail View'
    			},
    			body: {
    				contentId: 'StatusContainer',
    				className: 'WindowBody  __styleName__PageBODY'
    			},
    			footer: {
    				buttons: []
    			},
    			modal: false,
    			autoShow: false,
    			onClose: function(buttonPressed) {
    				//this does nothing, because this window does not specify any buttons in the footer section.
    				return true;
    			}
    		});
    %txt%
    
    ?DetailViewFloatingWindow
    
    end with 
    end function 
    
    %>

    Re: a5_AJAX_window()

    Try changing "autoShow: false," to "autoShow: true,".

    Also, be aware that the variable "StatusContainer_FLOATING_WINDOW" will only exist in the scope of the ajax response handler - therefore you will not be able to access it in the page after the ajax response has been handled.

    An alternate way of getting a window to be shown on a response is to create the window when the page is initially loaded (leaving "autoShow" to be "false"), and then to insert the code to show the window on the callback response. In this case:

    Code:
    StatusContainer_FLOATING_WINDOW.show();
    The window has two ways in which it can get its content: from an HTML string paced in, or from an HTML element already on the page (as you are currently doing).

    If "StatusContainer" is being filled with differnt HTML on the response, you could possibly switch to feeding the "StatusContainer_FLOATING_WINDOW" object that HTML. For example:

    Code:
    StatusContainer_FLOATING_WINDOW.body.html = 'Hello world';
    StatusContainer_FLOATING_WINDOW.show();
    Also, if you merely wish to display a message to the user, you might consider using the "a5_msg_box.show()" function, that wraps a window control, and provides a quicker way of genreating generic message boxes (you can still place any HTML in the message box, so INPUTs, TEXTAREAs, and SELECTs should work).

    Hope that helps,

      Re: a5_AJAX_window()

      Thanks Eavan -

      Been teaching all day so will get back to this later.

      What I'm looking to do is take a couple pieces that are taking up too much grid space and put them into a popup window. Sort of like the Detail component in the Web Apps samples, but not exactly.

      The popup window will have fields with checkboxes and a Submit button as would any other dialog to record the user input to the appropriate record.

      I think I'm on the right track but will have to fiddle some more...

        Re: a5_AJAX_window()

        Well, finally back to this one. It seems clear to me that the button I've devised isn't even calling the AJAX page. What's wrong with this:?

        Code:
        <button id="windowFromContent" onclick="a5_AJAX_Callback('A4_ContentWindow.Ajax.A5W','');" > Test Button</button>

          I don't see anything wrong - might be something in you AJAX A5W page.

          If you are not already, you'll want to use a combination of FireFox, and FireBug (debug for firefox). FireBug will show you pretty much everything that goes on in the browser - specifically what is getting sent to the server, and what is being returned. It is probably the best thing since sliced bread.

            Well, Eavan, you can see the button I'm using to call the page.

            And I've shown you the A5 script and made the change you suggested to get the window.

            Nothing. Nada.

            And I'm using FF3 and Firebug. Guess I'll resume digging with my teaspoon...

              Re: a5_AJAX_window()

              Let me start this one afresh maybe. I need to display, effectively, a dialog component or grid in an AJAX Window.

              How? The sample code that comes with A5 is just simply daunting and my customer needs something now. I have neither the time or money to invest in trying to modify the sample code to fit my needs. But the AJAX window appears to be a relatively simple construct that is worth pursuing. Or maybe I oughta be taking another approach?

                $('form1').style.display = '';
                
                //-->
                </script>
                A5W page named "__ajax_windowExp.ajax.a5w":

                Code:
                <%a5
                
                dim __action as c = default ""
                
                if __action = "loadForm" then
                	' code that actually fills in the form with useful values here - currently I hard coded it.
                	' '$svs' is used to set the value of a form control - if you are setting multiple values (i.e. select list, checkbox group), then use JSON array syntax (['value1','value2','valueN']).
                	?"$svs('firstname','Eavan');"
                	?"$svs('lastname','Chambliss');"
                	?"formWindow.show();"
                else if __action = "saveForm" then
                	dim firstname as c = default ""
                	dim lastname as c = default ""
                	
                	' code to save value here
                	
                	
                	' obviously not required - but just to prove it got here.
                	?"alert('You\'ve save the form...\nName: "+firstname+" "+lastname+"');"
                end if
                
                %>

                Basically, we create the form initially, place it in the window by using "contentId", and then fill in and save the values in the form via callbacks.

                For a grid, it would probably be easier to not use the "contentId", but rather construct the HTML for the grid on the server. Opening the window would then be like this:

                Code:
                formWindow.body.html = '{Grid HTML Here}';
                formWindow.show();
                You could still use "contentId", and just fill in the "innerHTML" of the DIV you are using for the "contentId" - this would allow you to navigate the grid via AJAX, and not close the window:

                Code:
                $('form1').innerHTML = '{Grid HTML Here}';
                formWindow.show();
                And on a navigate just do:

                Code:
                $('form1').innerHTML = '{Grid HTML Here}';
                Hope that helps,

                  Thanks Eavan - that does help. Finally gives me a workable, understandable base. I need to show a form with several logical/checkboxed fields, filled with values appropriate to a particular record ID - I think I know how to run with what you've supplied.

                  I appreciate your extra effort, and as others work to learn this, what you've just offered will have lasting value.

                      Re: a5_AJAX_window()

                      The a5_AJAX_window() takes a javascript object containing settings that define the window. These properties can include style information. Below is a mock-up of a window with just the style properties in the settings object:

                      Code:
                      a5_AJAX_window({
                      	className: '', // ClassName for the DIV that contains the entire window
                      	lockUIClassName: '', // ClassName for the DIV that will be used to lock the UI if the window is modal
                      	title: {
                      		className: '', // ClassName for the title element
                      		imageClose: '', // Close button image URL
                      	},
                      	body: {
                      		className: '' // ClassName for the DIV that contains the "body" of the window
                      	},
                      	footer: {
                      		className: '' // ClassName for the DIV that contains the footer (i.e. buttons)
                      	}
                      });
                      Just create a stylesheet with classes for each part of the window you would like to style, and then place those class names in the corresponding property in the window settings object.
