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.

    Re: Get Record Count of List using javascript

    Is there a way to get the count of the number of records in a list AFTER it has been filtered?
    Thanks,

      Have you tried using the List-Record Count that is under Defined Controls on a ux component?

        I also use Selwyn's suggestion in this thread to get the count in order to use it in my code.

          Re: Get Record Count of List using javascript

          are you talking about a server-side filter or a client-side filter?

          if you are using a server-side filter then my post from 12/18/2014 applies

          Code:
          var lObj = {dialog.object}.getControl('ID_of_your_list');
          var count = lObj._state.recordCount;
          alert(count);
          if you are using a client-side filter then you can read the length of the _rData array property of the list. the _rData is the filtered data in the list

          Code:
          var lObj = {dialog.object}.getControl('ID_of_your_list');
          var count = lObj._rData.length;
          alert(count);

            Thanks, Selwyn and Carol. Answered in less than 15 minutes. Where else can one get that type of support?
            Selwyn, the client side is what I am interested in.
            Thanks again.

              Re: Get Record Count of List using javascript

              This is the code of Selwyn
              var lObj = {dialog.object}.getControl('ID_of_your_list');
              var count = lObj._state.recordCount;
              alert(count);

              How do I count the number of rows in a not yet synchronized data? The above code returns zero , when I tried to save and synchronize the data on a list control and then run the code above in a button the alert says 'undefined'.

                The code you are using is appropriate when you have applied a server-side query to List. Say for example you have a list that is based on a sql table. Say also that the list is paginated and you are displaying 10 rows of data per page. The query that the list is based on might have a large number of rows, but the List always only shows 10 record (unless you are on the Last 'page' of data - in which case the List might show less than 10 rows). But you want to know how many records are in the List query, not how many records the List is currently showing (which is 10). In this scenario, list._state.recordCount would give you the answer you want.

                But your scenario is completely different. You want to know how many rows are in the list. The list data is in an array called _data. So you just need to return the length of this array. For example:

                Code:
                var lObj = {dialog.object}.getControl('ID_of_your_list');
                var count = lObj._data.length;
                alert(count);

                In addition, the List documentation documents a method to get the number of unsynchronized updated, edits and deletes.

                  Thanks so much! Hope you can point me in the right direction to enable lookup items availability when offline on a list control. the data are available but the problem is that lookup list are not available when offline.what could be the right property setting that I missed here?
