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.

  • Offline lists and view boxes

    I have a list of wine, 7,000 rows.

    I am using the suggested method of reducing the number of rows before I save the list.
    My client wishes to use the application offline.

    From the list of wine, I have created a child list of wine to be "Moved" from one location to another. This list has a detail view and the user goes through the list of wine and flags the wine as Moved. This works well.

    My question is how do I display All wines that are to be moved? I imagine a viewbox or list to display this data. I know it must be on the device but how do I access it?Offline Question..png

    Currently I am online and it is no problem going back to the server.

    I am using the suggested method of reducing the number of rows before I save the list.
    Without some details about this, it could mean several things. What are you doing as the "suggested method..."? You mention you want to be offline... so... "before I save the list" where?

    Is this a web app or a PhoneGap Build app? What version/build of Alpha are you using?

      Your image shows 3 lists. Isn't list 2 a list of all wines to be moved? What am I missing?

        David, I am using 4346.

        Suggested method, filter the list before starting. So I think the user will have a maximum of 1,500 rows.

        The list is being stored to local storage on an iPad. Currently, the program is browser based.


        List one is all wines (Moved or not moved)

        List three is a list of all Wines that have been moved.

        List two is the detail view of the selected row in List one.

        It is possible when the user moves wine, the wine is moved to multiple locations.

        So 3 bottles to Location A
        3 bottles to location B
        6 remaining bottles are not moved.

        So list one remains unchanged.
        List 2 has 2 entries. For the selected row.

        Loc a and loc b

        List 3 shows all movements. ("Saved")

        So by Saved I mean persisted on the iPad but not Synchronised to the server.

        In the database, I have 2 tables.

        Wine a list of all wine (Moved or unmoved)
        Wine_Moved details of the Qty wine name and new location.

          Michael, I'm sure you can but you may have to be creative.

          Here is some sample code for writing to a custom list.

          var data = {};
          data.Num = {dialog.object}._ListNum;
          data.Revenue_Type = {dialog.Object}.getValue('Revenue_Type');
          data.Revenue = {dialog.Object}.getValue('Revenue');
          //define optional settings
          var ops = {};
          ops.setFocusToTargetRow = true;
          //get a pointer to the List control and then call the .addTableRow() method
          var listObj = {dialog.Object}.getControl('Revenue');
          There is also: listObj.updateTableRow(primaryKey,data,ops);

          But I'm not sure you even need that. You can read from list one and write to list 3 using regular UX list methods. I guess that I don't see this as a big problem.

            Thanks, Peter I was so focused on the save to the detail view (List 2) that I overlooked the simplicity of appending a row to list 3. List 3 is only for display until it can be updated by the server.
