  You can identify control using sender argument.

  like as

   

  public function values()
  {
  string DropDownList_ID=((DropDownList)sender).ID;
  }

  best regard

  Instead of Passing the name of the dropdown, pass the control to the function and in that function directly do the databinding. By this approach there is no need of passing the name of control.

  (This below is sample example only for understanding puposes)

  For eg

  Function  BindDropDown( ddState  System.webcontrols.dropdownlist )

  { ddState.DataBind();

  }
