Please correct the requirement, its not understandable. On what event you need to perform operation on that and what that label contains

You're probably trying to call FindControl on the DataList itself.
That is not possible because there is no item of type Label with the given ID. Instead there are a lot of templated DataList items each containing 2 labels with the IDs "Label1" and "Label2". Due to that you have to call FindControl on the DataList's items.

C#

foreach( var item in DataList1.Items )
{
    Label label1 = (Label)item.FindControl( "Label1" );
    ...
}
