[CLOSED] How to View and Get Dynamically loaded user controls
Hi all,
We are working on the following requirement,
In a user control we have a gridpanel. In a page we are loading that user control many times and assigning data to each user control's store.
Here my issues are
1. with the following code we are unable to view the gridpanels
2. How to get/find dynamically created gridpanels from code behind?
3. How can we find the selected rows from each gridpanel ?
Here is the sample code to reproduce the issue,
Aspx code
========

Thank you
