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.

    Retrieving Values from a Grid Component

    Could somebody please let me know how I can retrieve values from a grid to use in a Dialogue component. The Dialog isn't linked to the grid, but certain fields are common and I would like to populate those within the Dialogue when openend.

    Hi Clive,

    Welcome to the Alpha forum.

    You will need to look at grid events to get e. values and set the values to session.variables.

      Maybe this will help.
      Go to: http://news.alphasoftware.com/V11Pre...s_v11.htm#Misc

      Look at the D21 video in the Dialog section of videos.
      There are also others about moving data from grids to dialogs.

      If I actually knew the answer, I would give it.

        Thanks Keith - I will play around with the session variables and see if I can get it to work.

          Thanks John

          I've watched the entire set of Dailog videos 3 times already and the problem with D21 is that the Dialog is bound to the Grid and the onclick event retrieves the Primary Key from the Grid specified in the Populate Dialogue with Data from the Table and then specifying the Primary Key field.

          I think somewhere between D21, D24 and D28 the answer lies, but I have spent close on 50 hours now and still can't get a basic value back from the Grid. I'll try Keith suggestion and see whether I can get the Grid Objetcs values for the current row into session variables and then update the Dialog component with these values.

          For a newbie this seems extremely difficult with very little actual examples around.....but hopefully once I've managed to do this I will be able to post the solution.

            Hi Clive,

            Sometimes people want to achieve a particular result and think there is only one way to do it. Perhaps trying to capture data from a grid to use in a Dialogue component is not the best way. Could you give us a better idea of what it is you actually want to do.

              Clive,

              What is your setup? You have a dialog & a grid on the same A5W page and then what is it you want to achieve?

                Clive,

                Take a look at video M41 (you will need prerelease build 3851 or above http://downloads.alphasoftware.com/A...easenotes.html )

                  Re: Retrieving Values from a Grid Component

                  I have Grid that contains a Song Code , Song Title and Composers (very basic) and a button - LOG A QUERY , which on click opens a Dialogue component for the user to log a query against the particular song record. The Query Dialog is not related / bound and I would like to populate the Dialogue component with the song code and will post this information to another Database table. User will then be able to view the queries logged against the particular song and it will function very much like this msgboard - A new query will be the THREAD and othe users can post against it...This is the easy bit - getting the Song Code into the dialogue is the problem.

                  Selwyn has provided me with a method that does work but involves two clicks and to streamline this I need global known variables. A rather tricky task for a novice A5 user.

                    I am curious about your statement: - and will post this info. to another DB table.
                    This sounds like something I am struggling with, I want to add data and save to a different table.
                    I'm just adding data to the original grid, where you are opening a dialog to enter the new data.
                    I'm guessing that if you bind the dialog to the grid, you would have to save to the original table
                    the grid data came from.

                    How would you save to another(different) table than the original table that populated the grid?

                    See my post Hijacking the ajax callback, started yesterday, it is still on the first page of this forum
                    at this time.

                    Thanks,
                    John

                      Did you look at the video M41? It is exactly what you are looking for.

                        Re: Retrieving Values from a Grid Component

                        Thanks for all the posts and help on this Thread and unfortunatrly M41 does not cater for what I wanted to do. I needed to get values from a GRID into a DIALOG which is not bound to the GRID containing the "onclick" event that opens the DIALOG, but is instead bound to another table which contains certain of the fields from the grid....it is sort of exactly what the messgae board does....but starting a new thread from within an existing thread....if that makes sense.

                        Compliments of Selwyn at Alpha Software, below are two very useful videos explaining exactly what it is that I wanted to achieve and how to get around this problem - achieve it. I trust that this will be very useful to many users.
