Use Place holder control to place the user control dynamically.
Here is some lines:

    string userControlName = "UserControl1.ascx"; 
 
    Control control1 ;
    control1 = LoadControl( userControlName );
    placeHolderControl1.Controls.Clear();
    placeHolderControl1.Controls.Add( control1 );
