Grid Question

[chadbrown]

Hi everyone i have a script that i want to run on a Grid before the user starts to enter information into the grid, how would I do that? or maybe use a button. I cant figure out how to add the xbasic code to a button?

Thanks in advance.

Re: Grid Question

I'm not clear enough on what you want to do to be sure what to suggest.

A couple ideas maybe:

Every .A5W page can have or call XBasic right on the page. But that runs when the page loads (generally speaking) so I dunno if that's what you want.

Is it OK if the user presses a button before entering data? In which case, you could add a dialog component with an Advanced button onto the same page as your grid.

I think we'll need a little more explanation to hit the nail squarely for you.

Re: Grid Question

I want to have a page that when the user clicks an advanced button it runs a script. That script is an import function that I already have. After that script is run there is a field with a lookup which they can then select the record that they just imported and then the fields will be filled in. It wouldnt matter to me if it was a dialog or a grid. I just seems to be so much easier to use a grid. On submit it would then just redirect to itself. Or the page could call the script upon arrival to the page I tried this but it gave me a stack underflow error, and I am not sure what that means.

Steve,
I'm not sure if the import I have set up will look for the file located on the server, Its a mapped drive but maybe I have to change the import to look for it in the webroot directory. I am posting the import code for you all to have a quick peek.Thanks I hope this helps.

Re: Grid Question

I did not read through the entire script, but you have to change your approach. You cannot use ANY function that calls a dialog, such as the UI_...() functions. Most likely you would start out with a Dialog, not a grid. Ask your questions in the Dialog, use the AfterValidate event to do whatever your script does.

If you are trying to import a file from the users computer to a database on your server, you can't. You first have to UPLOAD any file (or use FTP, or other functions, but you cannot "import".). That and all the "topparent" references have to go, there isn't any parent. Review each of the functions you use in the Help documentation and confirm they can be used on the web.

Re: Grid Question

Thanks Steve for the post, the import file is already on the server through another program so there is no upload needed. My original thought was to do a straight import but from your earlier post I realize thats not going to happen and its easy for me to get the files put on the server being that they are such a small file.

Steve did you get my private message in regards to working on this and some other stuff for me or are you to busy?
