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.

    I would do this as a javascript loop through the list.
    Here's the pseudocode:
    get a pointer to the list
    get the count of the items in the list
    set two variables: checkCount and cashCount
    set each variable = 0
    loop through the list
    add one to checkCount for each check, and add one to cashCount for each cash transaction
    display the results, either as an alert or stuff the values into fields on the form

    Something like this

    var lObj = {dilog.object}.getControl('list1');
    var _d = lObj._data;
    var len = _d.length;
    var checkCount = 0;
    var cashCount = 0;

    for (i=0;i<len;i++){
    if (_d[i].TransactionType == 'Check') {
    checkCount = checkCount + 1;
    {
    if (_d[i].TransactionType == 'Cash') {
    cashCount = cashCount + 1;
    {


    }
    {dialog.Object}.setValue('CHECK_COUNTER','This deposit has ' + checkCount + ' check transactions.');
    {dialog.Object}.setValue('CASH_COUNTER','This deposit has ' + cashCount + ' cash transactions.');

    You will need to adjust the text in red to match your controls.

    (by the way, I use single quotes in Alpha when writing javascript, but that may be a personal preference, not a requirement)

    Hope that helps.

    There are different ways to do this. Are you looking for a client-side count, or a server-side count?

    Perhaps an arbitrary column can be added to your list's SQL statement. You can use CASE in the SQL statement to set a 1 if it's a check. Then in the list control turn on the summary values and add up the new column.

    Here is the SQL example...

    Code:
    SELECT
        *,
        CASE
            WHEN Payment_Type = 'CHECK' THEN 1 ELSE 0
        END AS Check_Count
    FROM
        dbo.Invoice_Payments
    For counting and totaling based on data in a list control check out the list event afterClientSideSummaryCompute.

    This would likely have to be a separate SQL query, irrespective of the list itself (as an ajax callback) where you insert the count into whatever control you'd like. You can link the ajax callback to one of the list events so that they populate around the same time, or in the same setTimeout function that you already have.

    I'm sure there is also a way to conditionally loop through your entire dataset in the list clientside so you don't have to make another callback, but it isn't easy, and a quick count query costs virtually nothing.

    UX List "Count if"

    I feel like this is something easy, but I just can't seem to figure it out.

    Have a list control in a UX. It's showing transactions on a deposit (filtered by deposit date and deposit number). Wanting to display a count of checks vs cash. We have a field in the list that shows payment type.

    I can get a count of records in the list

    Code:
    var count = {dialog.object}.getListServerSideSummaryValue('CONTRIBUTIONS','ID_NUMBER','COUNT');
    
    setTimeout(function() {
    {dialog.Object}.setValue('COUNTER',"This deposit has "+count+" transactions.");
    },100);
    with COUNTER being a label control that is updated by the javascript. The Timeout was to give the list time to populate.

    Is there a way to conditionally count? i.e. count where payment_type = "Check"
Working...
