Validator help 1

[Rexxx]

I'm using a panel form and if a certain textbox has an entry then I need for another certain textbox to require an entry. This validator is to be I believe a client side validator so that tabbing through the form will display the error (i.e.,not the need to display the error by submission of the form).

I've looked at compare validator and not sure that will do. May need a custom validator. Can anyone help? I've tried developing a custom validator but having trouble. Can someone provide an example (using ASPX VB not C#)?

To do true custom client side validation takes a bit of massaging. I would suggest you read Isadore's FAQ on the subject... hers is specifically pointed towards calculations, but the same methodology can be applied to validation:

Rexxx:

Isadore's faq is a great start, but the validator controls in asp.net have one benefit over simply using javascript:
they validate on the server as well as the client. This is important if your user has javascript turned off in his browser (which would mean the validation code would never fire).

Your best bet (although it would require a postback, but not necesarily a "submit" in the sense of a button click) might be to hide the second text box, and only show it if the first text box's TextChanged events shows that there is text in there.

Then, you could have a required validator for that text box (I 'believe' that the validator would only fire if the control is visible, but you'd have to prove that theory...I would, but I'm not at my work computer ).

Thats a start in the right direction anyway. Personally, I think you're definately better off with the validator controls.

Hey Rexxx,

I've posted a sample file showing a possible solution for your problem (or at the least a pointer to the right direction)

Just go to

http://www.gotdotnet.com/Community/Workspaces/Workspace.aspx?id=34310681-5344-4fdb-8825-cf1f736d1ab9

and join our forum workspace. Then go to the file download area (select the html version, NOT the windows version), and get the ValidatorEx files from the msmaxx folder.

I signed up and went to the site but cannot find the msmaxx folder (I see user folders but search found msmaxx). The only down load area I found was the .Net downloads and I don't see Windows or HTML there. ? Can you provide a more clear way to get there ? Thanks again.

Just click that, go through the steps, and as soon as i get the email from them and auth you, you'll be able to get to the download area

Sorry about that
