Default post back of an asp.imagebutton produce error

Hi all...
I have several buttons inside a repeater, they are links to external and internal pages. Some of the destinations are .htm pages. In this cases, the buttons are not working well, meaning that they are throwing errors. This can be solved if I add method="get" to the form, but the external link is still not working, forbidden by the external server, and other parts of the page start to thrown errors. This buttons are linked to data inside the database (the image and the postback url), so I'm looking for alternatives, any of them.. any ideas???

Can you post the errors you are getting as well as some samples of the HTML being generated for the buttons in question?

I can solve the internal error (just make the hmt page aspx on the fly)... but the other error (the external link) is a problem... maybe some code behind for that particular button will solve it??? maybe code behind for every button so i don't have problems with any button???

Sorry I can post the external error from here (proxy forbids the destination url from here... can't see the error)

The pages you're submitting to don't allow you to post to them.

Is there any reason you're doing this? Why not

a) Use server side logic that uses Response.Redirect(SomePage) or

b) Use a standard HyperLink with an ImageUrl set to your image.

Hope this helps,

Imar

Do you need to post something to the "alain_lipietz.htm" page? If not, you should just use a regular hyperlink.

If I browse directly to http://www.iniciativaverde.org.ar/alain_lipietz.htm it loads ok. But if I use the link on the home page I get the error you described:

HTTP Error 405 - The HTTP verb used to access this page is not allowed.
Internet Information Services (IIS)

If I look at the request details in FireFox/FireBug I see that the request is a post but the server responds with these this response header:

     Allow: OPTIONS, TRACE, GET, HEAD

which indicates that POST is not allowed. Is it possible that your server isn't configured to allow the POST verb for .htm files? This would make some sense because usually a regular .htm file can't do anything with a POST request.

This setting should be found in:
- IIS management console
- website or virtual directory properties
- "Home Directory" tab
- "Configuration..." button
- "Mappings"

I don't even see a application mapping for .htm which makes sense because IIS just delivers the htm file as is. It doesn't need to be mapped to any handler. But perhaps your configuration has this. It's also possible that there is a .NET setting that affects this as well, but I doubt that because in order for .NET to handle it, IIS needs to have a mapping for .htm to the ASP.NET ISAPI (aspnet_isapi.dll).

thanks peter and Imar... the idea of using an asp.hyperlink worked perfect :)

Peter: It was working before since they weren't any htm page on the site. Yesterday the guys add one and start crashing. Take in mind that the button bar is made on the fly by getting links from a table from the database, so my first idea was to use imagebuttons, but you are rigth I don't need to POST anything to the destination pages...

The 405 error is describe in the msdn, you need to add the page to the ISS to avoid it..

thank you (the two of you) very much
