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.

  • Skip Deleted Rows from Repeating Section during Iteration

    I'm repeating this as my attempts to find a work around are not ideal. If you iterate through a repeating section to do something, the deleted rows are still there with data in them. How do I exclude those rows from being counted when I iterate throught the repeating section?

    Thanks

    I've tried all afternoon to figure this out but need some help. I'm iterating through a repeating section to do some stuff and that is working fine. However, I need to skip any edited rows that were deleted. I've tried to figure out the e.repeatingSectionInfo[].deletedRows array by telling it not to perform on those, but to no avail. The iteration works except that I cannot figure out how to exclude any deleted rows.

    Thanks

    Here is what I'm basically doing:
    dim i as n
    dim count as n

    count=e.datasubmitted.MyField.size()
    for i=1 to count

    if e.datasubmitted.MyField[i] <> ""
    "do stuff a bunch of stuff"
    end if

    next i

    Anyone done this? I just do not know how to compare or exlude the deleted rows from the non deleted rows.

      Re: Skip Deleted Rows from Repeating Section during Iteration

      I have dealt with something similar by creating my own Delete image and then on its OnClick event, I do an ajax callback to a function that sets the value in my Amount field to zero. In a later Xbasic function that loops through the repeating records to submit them, I ignore any rows that have a zero in the Amount field. I'm 95% sure the following Xbasic could also be written in javascript and that is probably what I should do, but I'm so much more comfortable with Xbasic. Here's my Xbasic function if that helps:

      Code:
      function DeleteRow as c (e as p)
      
      'get the number of repeating rows on acreen
      dim n as n = e.dataSubmitted.PAYOR_ID.size()
      
      if n = 1 then 'do not let them delete the row.
      	'NOTE:  This will only work if trying to delete the first row when no other rows have been deleted.
      	'Alpha holds on to deleted rows so deletions of rows after this will always detect more than one row.
      	'But at least this will cut down some on having a user delete s row meaning no rows are displayed.
      	DeleteRow = "alert('Since there is only one row it cannot be deleted.  Make changes on this row as needed.');"
      	exit function	
      end if
      
      if n > 1 then 'there is more than one row so let them delete the current row
      	e._set.AMOUNT.value = 0	
      	DeleteRow = "{dialog.Object}.deleteRepeatingSectionRow('CONTAINER_1');"
      	exit function
      end if
      
      end function

        Re: Skip Deleted Rows from Repeating Section during Iteration

        Hey Carol-
        Thanks for the input. I'm iterating through the line items when they are submitted so if the user has deleted a line using the provided delete button, it is still there but of course the user believes it's gone. What I was trying to do was to exclude any deleted lines during iteration. I still don't know how to do that. I can exclude line based on a criteria such as a blank field but not if it's filled in then deleted. My current solution is to provide my own delete button so when the user presses it I can set values such that the line will be ignored during iteration and then deletes the line.

          Sounds like concept of your current solution is same as mine. It would be good to know how Alpha marks those lines as deleted so that we could refer to that during our iterations. I too wrestled with trying to figure that out and could not.

            It seems that you would want it to work like it does with a grid. When you delete a record from the grid the record is permanently deleted from the table and the grid is refreshed with the current data.

            Unless there is a reason that you do not want the records to be permanently deleted I would remove the record from the table then refresh the repeating section with the current data.

              Re: Skip Deleted Rows from Repeating Section during Iteration

              Frank, in my case I am submitting new records with the dialog and do my own insert via Xbasic. The dialog is not bound to tables. When you delete a record in a repeating section of dialog it is not really deleted from dialog, just hidden. Therefore, if you loop through repeating records to post them, those deleted ones get included in the loop. I think this is also what Chris is trying to avoid.

                OK I see,

                I do not use dialogs often as I have not found a reason to use that instead of a grid for data entry. There is probably something in the e object like e.isDeleted?

                  Hi Carol,

                  Can you please tell me what PAYOR_ID is referring to in your xbasic code? Is this from a linked table primary key?
                  I am trying to adapt this to work in my component.

                  Thanks,

                    Stephen, you can use the name of any field on your row to count the number of rows in the repeating section. PAYOR_ID is just one of my field names. It is not a primary key.

                        Re: Skip Deleted Rows from Repeating Section during Iteration

                        Try using this function

                        {dialog.object}._repeatingSectionLogicalToPhysicalRow(RepeatingSectionName,logicalRow);

                        If you read the documentation it gives you the row count with deletes and without.

                        It is useful for this type of problem
