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.

    semi-cascade dropdown

    How do I program a semi-cascading dropdown?
    I mean, I have a topic and a subtopic dropdowns. I want the subtopics to be able to be used at anytime, if the topic is not selected to show all subtopics, but if a topic is selected the subtopic then cascade based on the topic. Right now the if I cascade subtopic it is disabled until a topic is selected.

    Elliot,

    If you change your subtopic to a textbox control, then use an Auto-suggest list look-up and set a dynamic filter to equal the topic.

          Using an auto-suggest the user needs to know all the values, using dropdown the values are shown. The auto-suggest helps the user but does not explicitly shows all the values unless the user start typing.

            Use an Edit-combo like in the video then. The user can then push the down arrow to see the choices.

            I use auto suggest with the search type set to contains, then the user can start typing any letters in what he is looking for and it narrows down the more he types. It is a really quick method of finding the correct item of thousands.

              What I want is that the subtopics be shown (all of them) and be selectable without been completely dependent of the topics, but if the topics is selected then to filter the values.
