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.

Count of total records in virtualized list

    Count of total records in virtualized list

    I can easily get a count of total records in a non-virtualized list.

    However, all I have tried in a virtualized list gives me the count of the page size, not the total number of records in the list.

    I see that there is a Defined Control:
    List-Record count

    That puts something like this in the UX:
    Records: <span id="{dialog.componentname}.MYLIST1.RECORDCOUNT"></span>
    That is not doing me any good.
    Thoughts?
    Thanks,
    Jay

    Re: Count of total records in virtualized list

    Adding the Defined Control List-Record count gives me the total count of records in the List... not the count of records in the current virtualized page.

    What do you want to do with the total record count... and where do you want it. Do you need it in Javascript code? XBasic code? You say "That is not doing me any good"... but you don't say if the List-Record count is wrong... or you just can't use it the way you want to. There are other ways at getting the List total record count... but a bit more info will help pinpoint a solution.

      Re: Count of total records in virtualized list

      David,
      I may have mis-spoken (mis-spooked?).
      I was working with a list based on a stored procedure. When I went back to a list with a SQL table, the defined list count control worked fine. My hope is to show the (total) count of records that falls within the current filtering. If there is no filtering applied to the list, I hope to show the total count of records. I think what I will have to do is get the count of records returned by the stored procedure for the initial count of the records in the list, and then from there it seems the defined list count control works.
      Thanks for your quick response.

        The List-Record control doesn't work with a List based on a SP? If that's the case I'll have a look.

        When you say "count of records that falls within the current filtering" does that mean SP filtering? Client-side filtering? Server-side filtering?

        Could you detail what doesn't work?

          David,
          I would like to put this topic into abeyance until I figure out what all is working and what is not working. I'll post a video later, when I fully understand what is and isn't working.
          Thanks for your help.

            If my CRS disease hasn't advanced too far, I seem to remember when list control first came out I noted to Selwyn that the count was not available from an SP. He pointed out why, which of course made plenty of sense. I don't remember the details or have more to tell you, but worth mentioning I think.

              Thanks, Steve. I'll look into this further.
              Sorry to hear about your CRS disease. I know that CR stands for Can't Remember, but I am not sure what the S stands for. <grin>

                Re: Count of total records in virtualized list

                I get the count using this code ...

                Code:
                var lObj = {dialog.object}.getControl('list3');
                var count = lObj._rData.length;
                $('REC_COUNT').innerHTML = count;
                In one of my apps I have a list control that is set to a static data source. An xbasic function is used to get SQL data, via a stored procedure, and populates the list. The above code is ran after the list populates. My list uses dynamic virtualization.

                Hope that helps.
