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

    Sorry... can't resist... is Aloha the Hawaiian office of Alpha?

    var countRec = parseInt($('{dialog.componentname}.LIST1.RECORDCOUNT').innerHTML);

    The Defined Control, List-Record count, is a static text control, with data being rendered inside a <span> tag. So you need to get the innerHTML of the tag... where the value it. Then use parseInt to convert it to an integer.

    The List control, when "pageinated" holds that number of records... there are no more records in the list. You say you have a defined control that displays the total count... grab that.

    Re: Get Record Count of List using javascript

    The list control is paginated to 50 records at a time, but the deffined control for record count shows the total of records in the query, the 25,000. I need to get the total count of the records because the report is based on CurrentListFilter and I don't want it to have too many records .... So that code I used is just returning the total of the paginated records?

    Re: Get Record Count of List using javascript

    First of all... yikes... 25,000 in the List control. How long does that take to load?

    Anyway... I just tried this with your code... and if countRec is set below the threshold being tested, then the logic is ok. Do you have your List control set to Page data? Do you actually have 25,000 records loaded?

    Re: Get Record Count of List using javascript

    Thanks, David, but I just tried the code below when 25,000 records were in the list control, and it ignored the count and just ran my action to open the report. This is being called by a button outside of the list control:

    Code:
    var countRec = {dialog.Object}._listViewData.LIST1.length;
    
    if(countRec > 5000){
    	alert('The report would have '+countRec+' records based on your search.  To prevent server overload, reports cannot be opened if they have more than 5000 records.  Please narrow down your search.');  
    } else {
    	if(countRec > 1000){
    		var answer = confirm('The report requested has over 1000 records and will take several moments to open.  Is it OK to continue?');
    		if(answer == true) {
    			{grid.object}.runAction('ReportPayrollLedgerByEmp');
    		} else {
    			alert('The action to open the report has been cancelled.');
    		}
    	} else {
    		{grid.object}.runAction('ReportPayrollLedgerByEmp');
    	}
    }

    Re: Get Record Count of List using javascript

    I can never remember if there is a method to get a list count... however, here are a couple of ways to do this...

    Your code does work...

    Code:
    var myOb = {dialog.Object}.getControl('LIST1');
    var countRec = myOb._data.length;

    Outside the List control...

    Code:
    var x = {dialog.Object}._listViewData.LIST1.length;
    where LIST1 (I believe in caps) is the name of your list control.

    And inside the List, in the onListDraw event you could save the count into a {dialog} namespace variable, and then use it elsewhere.

    Code:
    {dialog.Object}._myListCount = data.length;

    In case someone is curious, here is the whole thing I am trying to run...

    Code:
    //the following one is from copying the one supplied by the defined Control to get record count 
    var countRec = {dialog.componentname}.list1.RECORDCOUNT;
    
    //I made the following one up
    var count = {dialog.Object}._getListRecordCount('LIST1');
    
    //I tried the following based on a thread in the forum
    var myOb = {dialog.Object}.getControl('LIST1');
    var countRec = myOb._data.length;
    
    if(countRec > 5000){
    	alert('The report would have '+countRec+' records based on your search.  To prevent server overload, reports cannot be opened if they have more than 5000 records.  Please narrow down your search.');  
    } else {
    	if(countRec > 1000){
    		var answer = confirm('The report requested has over 1000 records and will take several moments to open.  Is it OK to continue?');
    		if(answer == true) {
    			{grid.object}.runAction('ReportPayrollLedgerByEmp');
    		} else {
    			alert('The action to open the report has been cancelled.');
    		}
    	} else {
    		{grid.object}.runAction('ReportPayrollLedgerByEmp');
    	}
    }

    Get Record Count of List using javascript

    I am trying to get the record count in a List Control using javascript before opening a report. This is because I want to prevent opening a report if there are over a certain number of records. I have tried the following 3 things and none of them work...

    Code:
    //the following one is from copying the one supplied by the defined Control to get record count 
    var countRec = {dialog.componentname}.list1.RECORDCOUNT;
    
    //I made the following one up
    var count = {dialog.Object}._getListRecordCount('LIST1');
    
    //I tried the following based on a thread in the forum
    var myOb = {dialog.Object}.getControl('LIST1');
    var countRec = myOb._data.length;
Working...
