Hi,

I have a form in usercontrol and add this control on runtime when user click "add more option".

There is product section where user enter product details but when they need to enter more product features then need to click on "add more option", after clicking on add more option usercontrol form is added to the page. But after entering data when I try fetch the vale from the control getting null error. I could get ascx user control controls value in my aspx code behind.

If any have any idea please reply.

Thanks
Rajesh

Can you show some relevant code showing you usercontrol, how do you add it to the page and how do you try to read from it?

Not enough detail, but I think you're adding user control at runtime, not declarative in as?x.
In that case on post-back you need to make an instance of your control again and add it to the page before you can read from it. Best place to do this would be in OnInit or Page_Load.

through code behind I have added usercontrol in page_load()

Try to add it page OnInit override. That's earlier in page life-cycle so runtime will have a chance to parse values from request for you.
The other option is to read values by id directly from Request.Form[].
Without exact code I can't help you more.
