Get values from dynamically created controls

Hi,

I have some problem to get values from the dynamic controls.(language: c#)

On my screen there is dropdown control(left side, name: cmbSelect) and a blank space(right side).
On selecting a value from cmbSelect, my controls are populating in the blank space(dropdown or textbox or listbox etc. based on the selected value from cmbSelect).
Now click on OK button I want to get the value from the dynamically created control.

How will i find the value?

Any help or guidance will be reliable.

Regards
Bikram
