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.

  • custom control an javascript

    How can I add javascript to the oncklick-event of a custom control?
    Cannot find an example anywhere...
    Thanks for help,

    Re: custom control an javascript

    There's a property section named Custom Control Properties. In there, get into Definitions. Once in there you'll see, highlighted in yellow (thanks to Alpha - they're so good to us), the section you need to put your HTML code in. Here's a little sample that works well to create a button with an onClick event on it. What do you want to do in the onClick?

    <script type="text/javascript">
     function copyText()
    alert('hi there');
    <button onclick="copyText()">Copy Text</button>

      Re: custom control an javascript

      I have this in the onDblClick-event of a label control and want to do exactly the same in the custom control:
      when dblclick on the cell, set a variable and execute an action button.

      window['WelcheNummer'] = {Grid.RowNumber};
      var myPointer = {grid.componentName}_BUTTONS_KURZANZEIGE;

        Seems to be the right direction.
        But the problem I get is: if I put this code in the custom control it is working find in working preview.
        But when I put the grid on the a5w page, the javascript function is not executed when the button is clicked. Still it can be seen in firebug.
        Any idea?

          Not sure... but it's working here.

          I added a field to my grid (it was a textbox field, by default) and I changed it to a Custom Control field.

          In the Custom Control Properties Definition I put...

          <script type="text/javascript">
           function setWinVar()
          var rowNum = {Grid.Object}._selectedRow;
          window['WelcheNummer'] = rowNum;
          var myPointer = {grid.componentName}_BUTTONS_KURZANZEIGE;
          <label ondblclick="setWinVar()">Set Win Var and run Action Button</label>
          This code goes between the %html% tags.

          I created an Action button with the same name as yours. My action button just puts out an alert showing the window var.

          You'll notice that you can't use {Grid.RowNumber} in this case... you must use what's above in the code.

          I put this grid into an A5W page and all is well.

          The Custom Control Definition creates a label field, but you can create anything you want... you mentioned a label field... and it's running off an ondblclick event.

            Re: custom control an javascript

            As soon as I publish the page with the grid to the localhost I get this in firebug:
            ReferenceError: setWinVar is not defined

            But there migth be a completly different approach to solve my basic problem:
            I have a row-event that is fine in 5 of 7 cells. The two other cells show an image which has an event of its own. When I click on the image, its own event fires (which is ok) AND the row event fires (which I don't want in this case). Can I do anything to stop the row event?
            I already opened a new thread with this question, but no answer so far.
            Again, many thanks for your ideas!

                Re: custom control an javascript

                I found this one in a more sophisticated a5-sample, wich show how to use a pointer-var:
                onClick() calls the onclick-event.

                var myPointer = {grid.componentName}_BUTTONS_KURZANZEIGE;
                myPointer.html = 'New Button Text'
                myPointer.onClick = function() {alert('now say hello');}
                myPointer.layout = 'icon text';
                myPointer.icon = 'images/$$application.alpha.png.a5image';

                  Hey Andy... you'd think so, but; throws an error and myPoint.onClick(); doesn't.

                    oh, sorry, you're correct - i misread that it was the a5 element method being called.
