Hi
I have an asp.net application in which I have a parent form and in that on load I am adding sub forms dynamically  having a submit image button..
When I am clicking the button of one form then I am able to read the hidden variables  using request under parent form .But on clicking the second button the hidden variables of parent form are having null value although i have assign the value to them using context variables.
Please help me out how can i handle mulitple form action for same page
