Solution 1

Controls are page specific. If you want to expose a certain control values to other page then you can expose them using properties (get-set) .

Further, if you have page instance then you can use 'FindControl' method of the page to find a control of that page using control ID.

UPDATE:
You modified your question a little. Please don't delete once answered.
If you are looking to pass on the ID of control to various pages then you can use query string or sessions for the same.

Is these does not help, then it would be better to share the scenario you are working on.

UPDATE 2:
See, how answer can change as soon you tell your scenario. You simply need to design a User Control. Have the parameter controls in this user control and then use this user control on all the pages where you need.

I edited and answered this question. But can't find it anymore in your question list. Have you deleted it?

You cannot get the control id of a page in another page.
But there are ways you can get the value of a control.

Can you explain what you are trying to do?

It means that the PreviousPage property is not initialized.
Are you doing a cross page posting?
