Hi friends,
I working in a module which would look like Windows Explorer, a Folder tree on the left and a File and folder list on the right.
Loading the folder is working fine and loading the right pane to the selected tree node is also done. The right pane data are loaded dynamically. Each files and folders are Linkbutton generated on runtime. I am not able to retain that controls when any of the link button is clicked. I have added a Click event for the Linkbutton which would open that folder and loads the inner data. When the page postbacks, this linkbuttons are cleared and the Click event is not called since the Page lost that control.
Anybody have an idea to solve this problem?
Thanks in advance...

No Vasu. I have tried it.
The sad part is when the Page is postbacked all the Link Buttons created dynamically are cleared.

I am calling a method getDirectories() present in an Applet which returns a string value, am calling this from the javascript. When I run this script from the Internet Explorer, the getDirectories() returns “C:, D:” but when I am calling this method from the Firefox it returns [Object Event] but I am expecting “C:, D:”. Can you please help me what should I do to get the correct string value.
Thanks in Advance

If i disable cache will it work, if yes how to disable cache. The whole thing is in an .ascx (user control) page.

There is nothing like disabling cache. With so many cache tiers at IIS, Proxy, Upstream servers and Web browser level, you can not expect a perfect disabling of cache though. You can of course direct the element to expire from cache or not to be cached by a suitable (pragma) or other directive.

I have a page which adds a record to the database when I Click the submit button and it stays in the same page showing all values from the database in a datalist. My problem is that if I refresh the page, the last event fired , that is btnSubmit_Click is fired again and yet another a record is added to database. What will be the solution. Thanks in advance
