my problem was, when i am selecting the companies in the dropdownlist gridview user control is loading first and 2nd dropdownlist selected event is firing..

You should probably check the IsPostBack property and only populate the controls if it isn't a postback.

void Page_Load()
  if (!IsPostBack)
    // Populate the user controls.

But since you didn't show any code I'm just guessing.
