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.

    How to get the value of a List Control Field?

    I have a button in a UX component and a List with Detail View, on the button click event I created a sample on how to run or call a stored procedure, the code is from the alpha documentation, I embedded the code in the Text mode of the Click Event of the Button

    dim cn as sql::connection
    cn.open("{A5API='SQLServer', A5DBVersion=2008, Server='(local)', A5ANSINullPadWarn=Default, Trusted_connection=yes, Database='Northwind'}")
    dim args as sql::arguments
    args.add("cityName","Paris")
    cn.Execute("exec MyStoredProc @whatcity = :cityName",args)

    Notice that the argument value is hard coded( i dont know how to term it exactly) , I want the value to be coming from one of the Detail field on the List.
    How do I get the value of a List Control Field so I can put it as a dynamic argument?

    {dialog.object}.getValue('list::NameOfList::FieldNameInList') is what I have used to get the selected value from a list.

      Hi, Thanks for the reply, I tried the code below and it has an error
      dim cn as sql::connection
      cn.open("{A5API='SQLServer',A5DBVersion=2014,Server='MYSERVER\SQLEXPRESS',A5ANSINullPadWarn=Default,Trusted_connection=yes,Database='MyDB'}")
      dim args as sql::arguments
      args.add("EmployeeId",{dialog.object}.getValue('list::EMPLOYEE::EmpId'))
      cn.Execute("exec MyStoredProc @whatcity = :EmployeeId",args)
      cn.close()

      Note: If I explicitly Identify the EmployeeId say "2" then the code runs correctly, I tried to embed your code but I am not sure if it is the way to do it

        Jetson, the code you've been given to access data from a List control is client-side code. It's a method you'd run in Javascript to get data from a control.

        Since your original post was all XBasic, a javascript only solution, without understanding the relationship between client and server side, isn't much help.

        There is a bucket of information missing from your post, but let's take a guess at a solution. You're executing an Ajax Callback. Let's assume the Detail View controls of your List control has data in it... that you've selected an item in your List, and the Detail View has populated.

        In your Ajax Callback XBasic function you have access to a ton of variables. One of these is e.dataSubmitted. You'll see, in the XBasic function heading you created... something like...

        function myXBasicFunction as c (e as p)

        e carries a lot of information.

        For each control in your Detail View (plus pretty much every other data control) e.dataSubmitted will have a property for that control.

        E.g. You're looking for EmpId. Your Detail View section will have a control... EmpId. So... you'll have access to e.dataSubmitted.EmpId.

        This means your argument setting will be... assuming you've checked that EmpId actually has a value you can use.

        Code:
        args.set("EmployeeId",e.dataSubmitted.EmpId)
        And... you want to use args.set... not args.add.
