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.

Pass data among panels in the same UX component

    Re: Pass data among panels in the same UX component

    Understood... me too... Access, VB6, early (and very messy) .NET... and old.

    Getting and setting values is accomplished with the getValue and setValue methods.

    You're setting the text of a label so it's a bit different.

    Have a look at a couple of really good sections of the documentation...

    Getting and Setting Values and Attributes Core.JS
    Alpha Five Javascript Libraries

    There's a lot of handy stuff in there. Specially the a5.msgBox.show function.

    If you want to pass data around the client side then you would use the {dialog.Object} namespace instead of global javascript variables.

    E.g. Let's say you want to grab the value of a control... and keep it around for use in a bunch of other javascript functions

    Instead of saying

    myVar = {dialog.Object}.getValue("myControlName");

    You'd use...

    {dialog.Object}.yourUniquePropName = {dialog.Object}.getValue("myControlName");

    Now you can reference {dialog.Object}.yourUniquePropName in any client-side event or function within that UX component.

    yourUniquePropName becomes a property of {dialog.Object}.

    I usually name these something like {dialog.Object}.__myUniqueName

    putting the __ in front reminds me that it's mine... that I created it... and not Alpha's.

    Re: Pass data among panels in the same UX component

    Thanks for the explanation David. I'm, totally new to Alpha. Trying to figure out how can I do things that I used to do in VB6 (yes, I'm old). I have an idea or a application and I need to pass variables among screens/panels. I was trying to understand better what is the way to go forward about it.

    Re: Pass data among panels in the same UX component

    To take your example, you'd use the same button click event.

    If I understand... you want to click a button... read the value of a control and use that value to set the label of another control.

    So... in the same click event of your button you'd have the "get" and "set"... so to speak.


    Code:
    var myValue = {dialog.Object}.getValue(UXControlName);
    $('{dialog.Object}.V.R1.UXControlName').innerHTML = myValue;
    Just curious... why do you want to do this? Perfectly ok that you want to... just wondering.

    Re: Pass data among panels in the same UX component

    Thanks David. Where should I write the second line of code you have given above?

    If I understood correct, the first line goes as an inline-javascript for the button click event.

    Re: Pass data among panels in the same UX component

    So you want to change the "label" of a control to the "value" of a control... is that right?

    To get a value in a UX you will use the method...

    Code:
    var myValue = {dialog.Object}.getValue(UXControlName);
    To set the label you'd probably do something like...

    Code:
    $('{dialog.Object}.V.R1.UXControlName').innerHTML = myValue;

    Pass data among panels in the same UX component

    I looking for a way to pass data among panels in the same UX. Let's say I have a test box and a button in the first panel and a label in the second panel. What I want to do is populate label (on the second panel) with the text I put in the text box (first panel) after the button is clicked. Could anyone please guide me to the right direction on this?
Working...
