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.

    Window Position relative to other control in grid

    I have a v11 grid with a button that opens a dialogue.

    Due to the width of the dialogue I need to position it relative to another item on the grid row. The item that I want to align to is: DD_TITLE

    I have this working: {grid.componentname}.TD.R1.DD_TITLE

    The only problem is that the row is hardcoded - I need to make this dynamic so that it opens in line with each row.

    I have tried:

    But nothing seems to work.

    It must be easy to pass in the row number dynamically but I just can't figure it out - Any suggestions please ;-)


    Re: Window Position relative to other control in grid

    Hey Kevin,

    You have to be really, really specific in this case... we need more information. The solution, so some degree, depends on where you're using this code... in a client-side event or a server-side event... and which event.

    Post the Event, and/or where you're trying to do this. You can make it dynamic.

    Answers here are tested before posted (except by those who dont' need to 'cause they've memorized all of Alpha :) ). We need to match your conditions in order to test and then provide the best answer.


      Re: Window Position relative to other control in grid

      Hi David

      Sorry for the lack of detail.

      I have a v11 grid attached to a mysql table.

      I have added a button to each row in the grid. On the button I have an OnClick javascript event to open a grid component (Action Javascript) in a modal-popup. Everything works fine but I would like to position the popup just below the row I am on and under the client name. The client name field is DD_TITLE.

      Using {grid.componentname}.TD.R1.DD_TITLE in the window position relative section the modal popup opens perfectly for the first row button but because R1 is 'hardcoded' the window opens just beneath row 1 for all the same buttons on each row. I would like to know how I can make the popup open beneath the row that I click the button on.

      Thanks for all your help.


        Re: Window Position relative to other control in grid

        Thanks Kevin... that is a perfect question. And a really cool one too.

        There are two ways to get a row number in Alpha... depending on where you are. In a "local" javascript function... like a Button Click... {Grid.RowNumber} will get replaced with the row number and all is fine. However, in a global javascript function, the functions under Code, Client-Side Events, and for example afterGridSubmit, {Grid.RowNumber} won't work. In this case, if you want the rowNumber then you do this...

        //place this Javascript in your code, and then reference the rowNum variable.
        var rowNum = {Grid.Object}._selectedRow;
        So, when I run into a problem where one type of code won't work, I try the other. In this case it works... almost.

        {Grid.Object}._selectedRow does return the select row, when used in a Relative Position Control ID, but not fast enough. So, we need to set focus to the row you're on before calling the dialog.

        In your button call, the relative postion Control ID needs to be

        {grid.componentname}.TD.R' + {Grid.Object}._selectedRow + '.DD_TITLE
        Be aware of the single quote marks. When you're typing in your Control ID, it will seem that the quotes are not balanced, but note that Alpha5 puts in it's own quotes and so the result is balanced. Also be aware, that if you edit your ControID your single quote marks will be lost.

        Now, to get the row focused before the dialog call add another Action Javascript to the Button Click. Choose Inline Javascript and put this code in.

        And now move this Action Javascript line to the top, to be run before the dialog call.

        I hope that works for you.

          Hi David

          That is excellent. Thank you so much for the solution but more importantly for the full explanation. As they say: "Teach a man to fish..."

          I really appreciate your time and effort on this.
