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.

Dialog lookup issue text area field

  • Dialog lookup issue text area field

    I have a dialog with several fields defined as a text area. I made one field a lookup field (looks up a grid component) and suddenly my text area field went from 15 rows in size to 1 row in size. The Rows property is still set to 15. If I remove the lookup the text area field sizes correctly.

    I've done the same type of thing with text area fields in a grid without issue.

    Is this a bug with dialogs?

    Re: Dialog lookup issue text area field

    The problem here is that the textarea control gets changed to an input control when you add the Lookup. If the control type was not changed then all would be ok. You could ask the kind folks at Alpha not to change the type. In the meantime, try this... I found this function, but I'm unable to give credit to the author... no name... so... thanks to all brilliant coders out there... 'cause this is brilliant. I knew we had to change the control type, but that's not strictly possible. So I thought we might be able to replace one section with another and so found this function.

    In your TextArea control, there is a property in TextArea Properties - Control Javascript. Get in here and enter this code...

    Code:
    function replaceWithTextArea(elId){
     var input = document.getElementById(elId);
     var text = document.createElement('textarea');
     text.setAttribute('name', input.getAttribute('name'));
     text.setAttribute('id', input.getAttribute('id'));
     text.value = input.value;
     input.parentNode.replaceChild(text, input);
    }
    replaceWithTextArea('DLG1.V.R1.TEXTAREA4');
    
    $('{dialog.ComponentName}.V.R1.TEXTAREA4').rows="15";
    $('{dialog.ComponentName}.V.R1.TEXTAREA4').cols="20";
    $('{dialog.ComponentName}.V.R1.TEXTAREA4').setAttribute("class", "GrGrayEdit");
    My TextArea control is named "TEXTAREA4" so change that to your control name. You'll need to adjust the rows and cols a bit, because the lookup part makes the control a bit bigger. Overall, we're replacing the input control with a new TextArea control, and then setting it's features.

    You can move the function to the Javascript Fucntions section if you like... I just left it here for simplicity.

    This is too cool. It doesn't really fix anything, but rather, at runtime, it shoves what you want, where you want it.
