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.

    Getting list data in Xbasic function

    Hello All,

    I'm trying to get record id from a list and use that id in a stored procedure.

    I have done it many times using e.dataSubmitted.Fieldname what is the e. data for a list?


    Re: Getting list data in Xbasic function

    The for a list is the same as for any control, provided there is a value in the list selected.

    If none of the list rows have been selected, then it won't have a value.

    If you are doing it by clicking on the list, make sure you use the right event. For a list, I think the select event is your best bet, but not sure.


      Re: Getting list data in Xbasic function

      Hello Larry,

      Thanks for the reply. I was using e.dataSubmitted.List::TrainLink::trnid instead of e.dataSubmitted.TrainLink

      It works. Thanks :)


        Hi larry

        Hope you are well

        I noticed you replied to this post and I wonder if you advise on my issue around lists

        I have a list called Enquires and when a user presses a button I need to get a value from the first field in the list of the row selected and pass this to a SQL arguement

        Would you know I use e.datSubmitted or do have to do something the JSON e.__listdata

        thanks in advance



          If the value of the list is the same as the value of the first field, then you can use the value of the list. (You can set the list value in the properties.)

          If it is NOT the same as the value of the list, you have some choices.

          If the value of the list is the ID of the record, you could simply look up that value or any other value you want using SQL.

          OR, if you setup the list with a detail view, you can have any value in the detail view available with e.datasubmitted.fieldname. (This is the easiest way, and also the easiest to debug)

          Finally, I believe that in recent versions of Alpha, you can even submit the list values when make an Ajax callback. I haven't done that yet, but it is probably easy enough to learn.


            Hi John,

            if you are going to set an argument, you need to pass the list value into an object and have it set server side. Like mentioned above, if the value is the return value of the list (primary key likely), then you can just reference the list itself. If it’s a column in list, you can identify it.
            I think the cleanest is pass that value to a state variable and then grab it on the server side and set the argument using an xbasic method. State variables are available both client and server side. Arguments have to be set server side.

            Handy state reference:

            server-side (Xbasic)
            Set state variable - e._state.myvar1 = "alpha"
            Read state variable - myvar1 = e._state.myvar1

            Client side
            var myvar = {dialog.object}.stateInfo.myvar1;


            I can give you one of my template UX’s that I use as a starting place to mess with things in Alpha if you want. It’s based on northwinds and you can watch how values pass around. I have a text box in it that shows the values in your arguments and state as they change.



              I'm going to push my luck here. Is there a method to open a UX and populate it based on a value from the list control or a state variable?
     is a great site to test and share sql code


                Yes. Easiest way is to make the value of the field you want be the value of the list. (Generally the Primary Key of the record in question.)

                Then set an argument to the list value and use that argument when you open the UX.


                  Hi Wayne

                  Sorted thanks just needed the primary key so all good

                  it ended up being a typo :-(
