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.

  • Linked content grid total

    I need to calculate the sum of the total summary values of the linked contents grids and show the result on the parent control.
    Any chance to do this?

    Re: Linked content grid total


    Check the id of the total using Firebug in Firefox, will look like "GRID1.SUMM.YOURFIELDNAME.TOTAL" then get a pointer to it using getElementById and get the innerHTML value (you mee need to do some parsing to take care of decimal & thousands separators.

    Tell me and I'll forget; show me and I may remember; involve me and I'll understand

      Re: Linked content grid total

      I got it, Frank. I can take the totals and sum them. I have a little problem yet. I can`t take the total if the grid is colapsed. I have not found any option to expand all rows. Do you know how can I do that?

      For anyone who has the same problem:
      var num_obj = document.getElementById("GRID_DEVIZE_DET_DEVIZ_DET_FQHF_GRID_LISTA41.RECORDCOUNT.TOP");
      var tmp = 0;
      var total = 0;

      num_obj = parseInt(num_obj.innerHTML);
      if (isNaN(num_obj)) num_obj = 0;

      for (var i=1; i<=num_obj; i++)
      var str_obj = "GRID_DEVIZE_DET_DEVIZ_DET_FQHF_GRID_LISTA41_R" + i.toString() + "G1.SUMM.TOTAL_LINIE.TOTAL"
      tmp = parseFloat(document.getElementById(str_obj).innerHTML.split(",").join(""));
      if (!isNaN(tmp)) total += tmp;

        In fact I would like to have all rows collapsed, but as I have no alternative.

          Re: Linked content grid total

          The row expander grid initially does not exist so that's probably why you can't get a pointer. You could try to call a method to expand & collapse them upon grid render but that probably will result in some strange visual effects. I actually don't know if this whole approach is the smartest thing to do. If you are using SQL you may want to think of joining tables. The SQL query builder in Alpha is very powerful.

            Re: Linked content grid total

            Hi Frank,
            I made an ajax callback that return me the total and you have right, is the best solution. Only I disagree that sql builder in Alpha is powerful. I have a lot of SQL query that's work fine in MySQL Query Browser but Alpha is not able to interpret them, not know to show me the columns. When it is queries with subqueries.

            Thanks again for you help.
