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.

    Using SQL data in a Google Chart: How to add a buttonlist control in a UX component to change the SQL Query used

    Hello,
    This is really puzzling for me, and I wonder if anyone can help. I have reviewed the message board and the documentation but can not find the answer.

    The video called "Using SQL data in a google chart" is very good although it does not give details on how to include a control to change the actual SQL query used.
    This are the links to the videos:
    http://www.ajaxvideotutorials.com/V1...tingData_1.swf
    http://www.ajaxvideotutorials.com/V1...tingData_2.swf
    http://www.ajaxvideotutorials.com/V1...tingData_3.swf

    In this set of videos, they propose to use the server-side "OnDialogInitialize" event - to run the query and get the data. and after that to use the client-side "AfterGooglevisualization" event to run a javascript function and show the chart in the browser.

    My problem is the following:

    Together with the chart I have included buttonlist for the user to change 1 parameter ( for example the client code) and then through the "On click event" I make an ajax call back to the server in an attempt to modify the query and run the javascript function again to show the chart.

    The result is that the chart gets displayed again fine, however the actual data remains the same. I�m unable to change the data set.

    Can anyone help with this?

    Many thanks in adavanced!!!
    Best,
    Javier

    Javier,
    It sounds like you want to use a variable in your sql statement. Is that correct? If so, the Ajax callback should be almost identical to the initial Xbasic, with the exception/addition of a variable in the SQL statement. If so, you should set up an argument, populate it with the desired value, and run the debug to see what is happening.
    Sorry if this sounds vague, but you should try and break this down to the most simple process.
    I might even put three buttons on the UX, and hard code the values for the buttons. When you get that to work, swap out the hard coded values with the variables.
    Hope this helps.

      Thanks Jay.
      As sugested I run a debug to see what is happening and I get the array wanted for the chart.
      However, right at the end of the server side function and also get a message saying: "Delete p.aArgumentsboundtocontrols"
      I�m not sure if this is correct,
      Cheers,
      Javier
