Sometimes when opening a form or when clicking on an object on the form, the form goes inactive or opens in the background. Is there a way to prevent this from occurring programatically?
I have seen this from time to time, but I don't have any documented solution.
You could try to clear the users AUC cache and see if that helps.
I have found the answer to this question. It is related to a 3rd party addition that we have installed (IEM). I had to remove some code that they have that sets forms as modal (which ends up putting them in the background because of the base timeout function in AX because the code to make the form modal takes too long to execute). I had to make a change to Classes/SysSetupFormRun: Below is the code and where it was changed
public void activate(boolean _active)
{
;
// if (_active)
// PUL_Modal::construct().hookModal(this);
super(_active);
/*
if (_active)
PUL_Modal::construct().checkModal(this);
*/
}
This returns the activate method to its previous state and prevents forms from going modal.

Please refer to the following https://github.com/CD1010/BlazorWizard.git for this question. The sample is in StepActivations Branch
I have a page called DemoWizard, which incorporates a 3 step wizard. When i click the "Toggle Enabled" button, the second and third steps links should go to enabled or disabled state. It seems however, that the first time takes 2 clicks to turn off the headers, and the state is always behind.
So it appears that StateHasChanged() is not refreshing child states properly.
Note that the refresh() method was an attempt to get at least step2 to refresh properly, but to no avail.
Any idea why?
the click handler that does toggle is below.
void OnClick()
{
step2Enabled = !step2Enabled;
step3Enabled = !step3Enabled;
StateHasChanged();
Step2.Refresh();
}
Your code isn't showing up exactly as advertised, but i think what you need to do is add an event callback to the Blazorize CheckEdit component:
<Blazorize.CheckEdit #bind-Checked="#Parent.IsValid" CheckedChanged="#VerifyEnabledTabs">Check Me</Blazorise.CheckEdit>
where VerifyEnabledTabs is a method on the top level Wizard that can assess where you are and what is complete / filled / checked / whatever, to allow certain links to be active.
So I would like to be able to have a print button for entries in our database so users can print an entry via a print friendly "form".
My thought was to create a separate page, add labels and have those labels pull the relevant information.
I know I can add the open widget information via this code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showPage(app.pages.TestPrint);
But I'm running into a few problems:
I can't get the page to open in a new window. Is this possible?
window.open(app.pages.TestPrint);
Just gives me a blank page. Does the browser lose the widget source once the new window opens?
I can't get the print option (either onClick or onDataLoad) to print JUST the image (or widget). I run
window.print();
And it includes headers + scroll bars. Do I need to be running a client side script instead?
Any help would be appreciated. Thank you!
To get exactly what you'd want you'd have to do a lot of work.
Here is my suggested, simpler answer:
Don't open up a new tab. If you use showPage like you mention, and provide a "back" button on the page to go back to where you were, you'll get pretty much everything you need. If you don't want the back to show up when you print, then you can setVisibility(false) on the button before you print, then print, then setVisibility(true).
I'll give a quick summary of how you could do this with a new tab, but it's pretty involved so I can't go into details without trying it myself. The basic idea, is you want to open the page with a full URL, just like a user was navigating to it.
You can use #TestPrint to indicate which page you want to load. You also need the URL of your application, which as far as I can remember is only available in a server-side script using the Apps Script method: ScriptApp.getService().getUrl(). On top of this, you'll probably need to pass in the key so that your page knows what data to load.
So given this, you need to assemble a url by calling a server script, then appending the key property to it. In the end you want a url something like:
https://www.script.google.com/yourappaddress#TestPage?key=keyOfYourModel.
Then on TestPage you need to read the key, and load data for that key. (You can read the key using google.script.url).
Alternatively, I think there are some tricks you can play by opening a blank window and then writing directly to its DOM, but I've never tried that, and since Apps Script runs inside an iframe I'm not sure if it's possible. If I get a chance I'll play with it and update this answer, but for your own reference you could look here: create html page and print to new tab in javascript
I'm imagining something like that, except that your page an write it's html content. Something like:
var winPrint = window.open('', '_blank', 'left=0,top=0,width=800,height=600,toolbar=0,scrollbars=0,status=0');
winPrint.document.write(app.pages.TestPage.getElement().innerHTML);
winPrint.document.close();
winPrint.focus();
winPrint.print();
winPrint.close();
Hope one of those three options helps :)
So here is what I ended up doing. It isn't elegant, but it works.
I added a Print Button to a Page Fragment that pops up when a user edits a database entry.
Database Edit Button code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showDialog(app.pageFragments.FragmentName);
That Print Button goes to a different (full) Page and closes the Fragment.
Print Button Code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showPage(app.pages.ModelName_Print);
app.closeDialog();
I made sure to make the new Print Page was small enough so that Chrome fits it properly into a 8.5 x 11" page (728x975).
I then created a Panel that fills the page and populated the page with Labels
#datasource.item.FieldName
I then put the following into the onDataLoad for the Panel
window.print();
So now when the user presses the Print Button in the Fragment they are taken to this new page and after the data loads they automatically get a print dialog.
The only downside is that after printing the user has to use a back button I added to return to the database page.
1.
As far as I know, you cannot combine window.open with app.pages.*, because
window.open would require url parameter at least, while app.pages.* is essentially an internal routing mechanism provided by App Maker, and it returns page object back, suitable for for switching between pages, or opening dialogs.
2.
You would probably need to style your page first, so like it includes things you would like to have printed out. To do so please use #media print
ex: We have a button on the page and would like to hide it from print page
#media print {
.app-NewPage-Button1 {
display : none;
}
}
Hope it helps.
1. Here is how it is done, in a pop up window, without messing up the current page (client script):
function print(widget, title){
var content=widget.getElement().innerHTML;
var win = window.open('', 'printWindow', 'height=600,width=800');
win.document.write('<head><title>'+title+'/title></head>');
win.document.write('<body>'+content+'</body>');
win.document.close();
win.focus();
win.print();
win.close();
}
and the onclick handler for the button is:
print(widget.root.descendants.PageFragment1, 'test');
In this example, PageFragment1 is a page fragment on the current page, hidden by adding a style with namehidden with definition .hidden{display:none;} (this is different than visible which in App Maker seems to remove the item from the DOM). Works perfectly...
2. You cannot open pages from the app in another tab. In principle something like this would do it:
var w=window.parent.parent;
w.open(w.location.protocol+'//'+w.location.host+w.location.pathname+'#PrintPage', '_blank');
But since the app is running in frame nested two deep from the launching page, and with a different origin, you will not be able to access the url that you need (the above code results in a cross origin frame access error). So you would have to hard code the URL, which changes at deployment, so it gets ugly very fast. Not that you want to anyway, the load time of an app should discourage you from wanting to do that anyway.
I have created some form in which it sended a few items to the sales lines in sales order detail form. What I need now is some logic to check if salesquotation detail form is open in the background then close it. Can anyone help.
It is not best practice to close forms by code, the user should be in control.
But if you insist:
void close()
{
if (formRun && !formRun.closed())
formRun.close();
super();
}
This closes a child form (if not already closed) when closing the current form.
Of course this requires you to open the child form by code as explained here.
I would like to open a document after my ASP.NET page loads in a separate window. I would like to do this with the document not attempt to be blocked by a pop-up blocked. I tried and I am getting the prompt to ask if I would like to allow the popup. Is the best way to do this using a timer control or is there a better way in the lifecylce?
I have tried several events, but they are all launching the document prior to page load.
Fundamentally what you're trying to do is exactly the thing that pop-up blockers are designed to prevent - load a pop-up window without an explicit user interaction. There may be various tricks you could use to get around certain particular pop-up blockers, but you'll never be able to solve this in the general case.
The best solution is to have a link on your page to open the document in question in a new window. Pop-up blockers do not prevent links targeted to a new window.
I use
function openpage(page) {
if (document.getElementById('hf_open').value == 1) {
openChild(page, 'nueva');
document.getElementById('hf_open').value = 0;
}
}
and in the body onload ="openpage('whateverpage.aspx');"
and in an ASP.NET event I set if I want the popup to be open or not a particular time by setting hf_open to 1 if the pop up has to be opened at that time.
In Internet Explorer 7 with pop up blocker: turn on checked - it works.
How are users getting to your page? You could place the popup JavaScript in the link that takes users to your page.
You could use the onload JavaScript event.
function open_page()
{
popupWin = window.open('windowURL','windowName', ' resizable,dependent,status,width=500,height=400,left=0,top=0')
}
Then have the following body tag
<body onload="open_page()">
However, this won't get around your popup blocking issue.
Scenario is : old site which has lots of JS code already written. If user want to change all the alert messages to new age jazzy Div based alert which are very common using JQuery, YUI, Prototype... etc.
There are mainly tree JS dialogs
1. alert
To changes this its simple we just have to write new function which will show the div popup and show the message, after that override the window.alert
function showDivAlert(strMessage){
//div popup logic and code
}
window.alert = showDivAlert;
2. prompt
This too look easy to write function to accept the string and show the text box for input value. Now as return action is based on the click of "OK" button life is easy here.
function shoDivPromp(strMessage){
//div pop up to show the text box and accept input from the user
}
window.prompt = shoDivPromp;
3. confirm
Now above two were easy to override and modify the default dialogs but there is complication with the confirm.
However default JS confirm dialog stops JS execution and when user click OK or Cancel execution is resumed by determining the return value (true/false). But if we user div popup the execution is not stopped which is problem. We can still implement the confirm but in that case we have to bind methods for OK and CANCEL case which will be attached to OK and CANCEL button. With this function signature will be like.
function newConfirm(msg, fun OkAction(), fun CancelAction)
Now this is problem that this cant help me change the confirm dialog across the site as we did with alert();
Question
I am not sure whether its possible or not to achieve but i think can be using some JS pattern. So let me know if its possible.
Now this is problem that this cant help me change the confirm dialog across the site as we did with alert();
That's correct. It's not possible to reproduce the synchronous nature of the alert/confirm/prompt functions in native JavaScript. There is the non-standard method showModalDialog which can do it using a separate pop-up document, but it's not supported by all browsers and it's generally considered highly undesirable.
So the plug-in-replacement strategy isn't going to work. You are going to have to change every place you called these methods in the rest of the script.
The usual pattern is to do it using inline anonymous functions, to preserve the local variables using a closure, eg. replace:
function buttonclick() {
var id= this.id;
if (confirm('Are you sure you want to frob '+id+'?'))
frob(id);
wipe(id);
}
with:
function buttonclick() {
var id= this.id;
myConfirm('Are you sure you want to frob '+id+'?', function(confirmed) {
if (confirmed)
frob(id);
wipe(id);
});
}
If you need this to be preserved you would need to look at a further nested closure or function.bind to do it. If you have your call to confirm in a loop things get considerably more difficult.
Obviously you also have to ensure that critical global state doesn't change whilst the confirm box is up. Usually this risk is minimised by greying out the rest of the page with an overlay to stop clicks getting through. However if you have timeouts they can still fire.
All 3 methods actually stop js execution, not just the confirm, because they're all modal dialogs. Personally, I would try to keep everything as asynchronous as possible as modal dialogs prevent interaction with the current document.
Your best bet is to use callback functions from the new confirm popup as you suggested yourself.
I'm having a hard time understanding exactly what you want to achieve. It sounds like you want to do something like the following:
Run some javascript code
Display a "confirm" box
Wait until the ok button or cancel button is clicked
Continue code when user clicks ok, return when user clicks cancel.
The reason you want to do this is that overriding the function with something that makes use of callbacks would require rewriting each section of code that uses the confirm function. If you want my advice, I would go ahead and rewrite the code so that it performs asynchronously. There's no way you can delay script execution without locking up the document which includes the OK and Cancel actions of your dialog.
if you changed the roles Alert / Prompt / Confirm. slows the execution pending user interaction to run the following code.
Overriding these functions, the code continues its execution.
To achieve this you have to modify each part of the code and work as if you were with asynchronous functions.
Then you can use any plugin for windows as sexy-alert-box, and overwrite Alert / Prompt / Confirm
The function signature would simply be:
function newConfirm(msg, okAction, cancelAction);
and would be used as:
function newConfirm(msg, okAction, cancelAction){
var ok = doWhateverPromptIsNecessary();
if (ok) {
okAction();
} else {
cancelAction();
}
}
That is, to pass function "pointers" in to a function as arguments, simply pass in the function name without the (). The function signature is the same.
