Hi,

Im not sure if it is possible to call an ASP sub procedure in javascript, but i know vice versa is possible. Thanks

It's not possible to do either way natively. They run on entirely seperate platforms (The ASP Script executes on the server, and the JavaScript is executed by the browser on the client machine) so calls between the two won't work just like that.

You can however use ASP to write out bits of JavaScript to the response stream, and the browser will then execute it.

As for the other way round, you will have to get the JavaScript to make a request to the server in some way (Either changing the page location, submitting a form, or using the XmlHttp object). Parameters can be passed with query strings or form post values. The ASP Script can then handle the request, and execute the desired function or procedure.

Hi,

Thanks for your reply. Well, i am currently working on a user control (.ascx) file in Asp.net. What i want to do is to create an image list box using <div> tags to expand and collaspe whenever user clicks on the "more" or "close" link/button.

The above i have already settled it, the only problem i have now is to allow user to select image and display the selected image upon clicking. Which means i must have a postback to ensure that the selected image is updated and to display other images besides the selected image displayed, when user expand the <div> tags.

My user control is something like a dropdownlist, but instead of text able to display images. Currently, I am using server-side coding to generate the images. It is dynamic because it will create the number of <img> tags according to how many image files i have in the provided directory of folder.

What do you suggest i should do to go arround this problem?
