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.

  • Hide field based on radiobutton selection in same grid

    I know grid components are not the most flexible but has anyone figured out a way to hide a row (field) or disable the updateable property of a field at runtime in response to a radio button selection in the same grid.

    Example: Radio button to input/select gender. Based on the gender selected some fields are not relevant to fill in so hide them or disable their update property.

    I just don't want to create two separate grids for something like this but also don't want accidental data entry into the wrong fields.

    Suggestions besides dialog component :-)

    Re: Hide field based on radiobutton selection in same grid

    After so long saying this would be difficult, I decided to see if I could make this work - I DID (at least for this test case).

    I used a checkbox in my example, but the same concept should work for any control field. My checkbox is named OMIT and the field I want to disable is named NAME. And the Grid is named OUT. Adjust your code to match your conditions.

    You have to modify the HTML at run time, and you have to deal with the multiple rows of a grid.

    Insert the rows I have in red at the appropriate place:

    dim rowcnt as n with tmpl
    rowcnt = rows
    componentName = componentAlias
    end with

    Then this just before the </head> tag

    for x = 1 to rowcnt
    x_OUT.Output.Body.Grid_HTML = stritran(x_OUT.Output.Body.Grid_HTML,"id=\"V.R"+x+".OMIT\"","id=\"V.R"+x+".OMIT\" onclick=\"this.form.elements['V.R"+x+".NAME'].disabled = this.checked\"")

      Re: Hide field based on radiobutton selection in same grid

      Thanks Steve. Without having tried it yet your example strikes me as a one way only process so that if the checkbox is clicked the field stays omitted even when the check box is unchecked. I guess you can just refresh the page to get back the default state.
      I will give your example a try Monday. This will give me something to start playing with this week. Assuming it works for me I will need to figure out how the radio button can be used so that the fields affected can be disabled and enabled in case the user clicks the wrong one the first time.
      I'll report back. :-)

        Nope, it toggles the target field off/on.
