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.

    Populating dropdown via variable

    I have a grid that contains muliptle contacts for a given company. The grid can contain as many as 10 contacts with five titles each. Each title field has a dropdown where the user can choose from around 1000 differnt titles. The title table that is currently dynamically populating the dropdown is a sql table.

    Needless to say this grid loads extremely slowly. Is there a way, since each dropdown is refering to the same title table, to prefetch that table (as opposed to it loading 50 or so times). If so, how do I go about doing this?

    Re: Populating dropdown via variable

    When you define your Dropdown, choose a List Type of "Dynamic", then a datasource type as a Variable.

    The variable should be a crlf()-delimited list of values. Walk your way through the setup dialog for this; the help at the bottom of the dialog is also somewhat instructive.

      Re: Populating dropdown via variable

      Is it possible to set an "initial_value" in this scenario? I've got my variable properly created, but I haven't found a way to modify "initial_value" in the code. It seems that any code I enter gets processed BEFORE the standard A5-generated stuff - which then blanks out any value I may have tried to set. I haven't been able to find any approach (ie: Activate event) that will cause my 'override' to process correctly and/or after the standard A5 template code.

      The code I'm experimenting with (this is for a dropdownbox on a v10 Web Dialog Component) is:

      CurrentForm.Controls.MyDDB.dropdownbox.initial_value = "DEFAULT"
      or
      CurrentForm.Controls.MyDDB.initial_value = "DEFAULT"

      all to no apparent avail, regardless of where I place them. Substituting "initialvalue" for "initial_value" seems to have no effect, either, although that seems to be the property name used in the generated code.

      I see Peter Wayne's post: http://msgboard.alphasoftware.com/al...=initial_value
      but, if that is the right approach, I'm afraid I'm unclear as to where to place his code (modified for my circumstances, of course).

      Is it possible that .initialvalue is disabled for population by Variable?

        Ok, I think I've learned that my InitialValue must be present in the list of choices - or all bets are off.

        But I still haven't managed to get any sort of code in place that results in success.

        Have been playing around with Activate event, Advanced Properties, entering
        with tmpl.Variable_Info[2] (that appears to be the correct field/object), and .initialvalue but to no avail.
