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.

  • AJAX callback - how to update fields on an independent GRID?

    I have two independent grids GRID_A and GRID_B. They are independent to each other as they have NO link or parent/child relationship.
    When GRID_A is updated on the page, I have some calculations that need to update the summary rows (multiple rows) in the GRID_B.
    Both GRID_A and GRID_B are on a single a5w page - PAGE_AB.a5w.

    I have a button on GRID_A where I do a AJAX Callback to do this
    --Javascript on the Button.
    {grid.Object}.ajaxCallback('G','ALL','myfunction_123','','',{});

    The xbasic code need to do this
    1) Verification of displayed data on GRID_A
    2) Updates few fields on GRID_A
    3) Updates/recalculate values in multiple rows on GRID_B.

    I am able to do 1) and 2) above using the e._setRow... and e.V.R1... notation on the xBasic code based on earlier help - So No problem,
    but unable to do 3) how do I access GRID_B on the server code to read and update its rows/fields in the xBasic Code? - Help!

    Thanks.

    Re: AJAX callback - how to update fields on an independent GRID?

    I saw that there are various placeholders in java that can be used for Ajax Callbacks - Example: {Grid.object} and {dialog.object}.
    What is a lowest level (similar to root level or window level) placeholder that I can use for the Ajax Callback (also need a way to access it, if that exists)?
    My idea is to go to the lowest level object that I can access and then access the other objects on the windows (various Grid/UI/pages/etc) using their hardcoded names of those objects that I already have - once I am at the root. (Example: GRID_B in my example).
    {grid.Object}.ajaxCallback('G','ALL','myfunction_123','','',{})
    {dialog.Object}.ajaxCallback('G','ALL','myfunction_123','','',{})
    {LOWERT_LEVEL_OR_ROOT_NEED_HELP.Object}.ajaxCallback('G','ALL','myfunction_123','','',{})
    Please help!

      Just posted a similar problem. I will let you know if find a solution.

      Have you tried setting the grid to auto-refresh and then adding any xbasic that you would need to the initialize method of Grid B?

        Thanks.
        "Have you tried setting the grid to auto-refresh and then adding any xbasic that you would need to the initialize method of Grid B? "
        If I do the above then I may have access to displayed data from Grid B, but then will not have the displayed data from Grid A.
        I need both the displayed data from Grid A and Grid B at the same time to calculate the new (multi-row summary) values that will appear in GRID B.

          Re: AJAX callback - how to update fields on an independent GRID?

          I know Alpha Anywhere can do this but just not sure how, especially with the object oriented technology and having the right handle (pointer) to the objects that I do (see below).

          Using the http://www.screencast.com/t/ZTQxMGJhO where following what Jeff Cogswell has suggested, I am saving the name of a {Grid.object} placeholder to a global variable.
          Grid1 - onGridRender Client Side Event
          window['GRID_A']={Grid.object};
          Grid2 - onGridRender Client Side Event
          window['GRID_B']={Grid.object};

          Now, how do I send/post both these objects to the XBasic Code on the Server using the Ajax Callbacks - at the same time!
          I need data from all these rows in the GRID_A and also GRID_B on the server side code to do my processing/business logic.

          I am able to successfully send just the GRID_A data using
          window['GRID_A'].ajaxCallback('G','All','myfunction3','','',{});
          OR send just the GRID_B data using
          window['GRID_B'].ajaxCallback('G','All','myfunction3','','',{});

          But not both?

          How do I send All rows from both the GRID_A and GRID_B at the same time.
          Note: As you see I am not sending just one or two argument/value from the second GRID - need to send all the rows/fields from the second Grid.
          Help!
