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.

    linking field(s) are not updateable???

    I call grid 2 via a button on grid 1 (an onclick event to open a grid component). I use the link fields function to carry over a username field from one table to a child table.
    The fields get filled in properly, but when I submit, I get the (infamous) error:
    "Record cannot be inserted because the linking fields (s) are not updateable" .... etc.
    Both grids are updateble and the fields are of Control Type textbox. [Now this is where it gets interesting.] In a previous post from Selwyn, he mentioned looking at the xbasic of the grid to really see how the fleld is defined. I did, and, even though it's defined as an editable textbox, xbasic shows it as updateable = .f.

    Actually, this is what you want for this operation since we're copying a field from a master table to a child table and don't want it to be edited..... BUT why do we get the error about fields NOT being updateable. Is this a bug?? and if it is, it's been around a good while. I saw the exact same error message posted over 4 years ago.

    So...... is there a solution to get the child record submitted???

    TIA.. Joe

    Is this a bug??
    doubt that.
    "Record cannot be inserted because the linking fields (s) are not updateable
    probably correct.
    if you tell the grid1 and the fields it is based upon
    and the grid2 and the fields it is based upon
    someone may be able to find what is wrong and help you.

      I don't understand why you need to know the fields so perhaps a running example will help. http://162.226.17.60/index.a5w
      Click on "Button", then dirty the message field and click submit. You'll then see the error message.

      The userid is linked to useridemailto. All are Character fields (except the date). Both files use an autonumbered index field.

      I think you get the idea. On a particular record, click a button and send an email to that person. Anyway, that's where I'm heading.

      I hope this helps. I look forward to your thoughts. Thanks

        ok you can keep the fields.
        but why you need another grid to send email?
        can you not just open a dialog and send the email?
        the dialog can be populated with fields from the grid and email can be sent.
        do you need a record of all the emails sent?

          Re: linking field(s) are not updateable???

          I agree that there's always another way to skin the proverbial cat, but a record of the email is one reason I chose to do it this way.

          Now... don't lose the main subject. Why the error message? and if it's not a bug, how do I fix it??

            it is not a bug.
            when you have a linked grid the child grid is synchronized with the parent i.e
            when you bring out a child grid it show all the records that are related to the parent grid via the linking field.
            when you add a child record the linking field is automatically inserted so the child grid will be in sync with the parent. you cannot manually insert the linking field.
            as far as your grid, this is what I gather.
            you have or you are representing a real estate (hope so, from the example ) company. and the people sign in ( let's call them intruders)and they select a particular listing and they want more information ( since the example says the sign in name is the email to field ) if correct so far, then
            the grid should be read only, the intruders should not be allowed to modify any field. even if you think that you are copying the email address to the first field people can manipulate easily to damage your database or do unwanted stuff. if the function of the button is to send email to the signed in person then just write a code to do that than build another grid or dialog. all the information that is present in the grid should be available to harvest and send.
            also you are in version 11 and possibly move on to version 12. Arizona css is legacy, if you are using that may be consider the newer ones. for improved look and easy migration to the future.

              DAMMIT.... you are replying for the sake of a reply. Everything you said is all just rhetoric without substance of an answer to the original question !!

              If you can't answer the question, then shut the hell up

                Joe, I'm a beginner here (having misspent my youth on the desktop side) but when you populate the fields in the new child record are you trying to populate the "link" field in that record? If so, this may be unnecessary. I'd suggest NOT populating the link field in the new child. Perhaps Alpha will do this for you automatically.

                  well duh....
                  Nevermind. JUst ignore this thread and go on.

                  It's got to be a bug !!! I created another new grid and did everything one step at a time; watching very closely the "updateable = " in the xbasic code. This time around they all stayed to be = .t. and it all works as it's supposed to with no error message..... go figure...

                  If I can reproduce what I did, I'll submit it to Alpha
