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.

    Only add and edit new fields within a grid

    Good Afternoon,

    I have multiple grids linked together that require a login. When a user logs in they see all their information. What i want to accomplish is to allow the user only to add and edit new information without being able to edit any previous information within the grid. Anyone know how i can accomplish this.

    Re: Only add and edit new fields within a grid

    it is quite possible you may accomplish this.
    take a look at canUpdateRecord event
    and the datasubmitted.oldValues.your field name and datasubmitted.your field name
    you may be able to check if the old value does not exist then go ahead if not put a block
    I haven't tested this
    this is a thought process
    see if you can take it further.

      Re: Only add and edit new fields within a grid

      Another option would be to disable the field (enable/disable property) based on whether the field has any information in it (null, blank, 0, etc). Once they 'save' the record, the information would be locked.

      This of course assumes that by 'not edit previous information' means that once they've entered the new data, you don't want them to edit it after saving.

        Re: Only add and edit new fields within a grid

        Thanks for the input so far. However, i have come up with a solution that; i am just having trouble getting it to work. Whenever a user tries to update or input new information it will look at the date field and validate against it. Using a simple expression it works fine with one date for example Jun-30-2013. However, i need to include Dec-31-2013 and every time i use some syntax to include it validation doesn't work. Can someone please help me with getting the simple expression to work or how would i input the multiple date fields in a custom expression.


          Re: Only add and edit new fields within a grid

          why not post your expression and someone will correct it to proper one.
          more likely you are not referencing the date in both parts for example
          if some_date < reference1_date .and. some_date > reference2_date
          see some_date appears on both sides like that.
          thanks for reading
