I have the Id of an object(a DropDownList web control) as a string of
course and I want to get the object based on this Id. Is there a way to
do this in C#?

Hi Eugene,

Have a look at the FindControl() method. It's a member of the Control class,
so it exists on the Page object and all the controls in the page. You'll
probably just want to do FindControl(controlName) from your code behind.

note that FindControl isn't as cool as it used to be, in that it doesn't =
search beyond the current INamingContainer. So Page.FindControl will =
only look at Page-level controls, and nothing inside a UserControl or =
DataGrid or any other INamingContainer.

This is true, but since these controls do implement INamingContainer
themselves, you could say
Page.FindControl(controlOnPage).FindControl(controlYouWant);
