C# - DropDownList Selected Item Incorrect When Using FindControl?

I have a number of dropdownlists embedded in a gridview. When I submit the page I loop through all the rows of the gridview and use the findcontrol method to get the dropdownlist e.g:

foreach (GridViewRow gvrItem in gvItems.Rows)
{
DropDownList ddlOption = gvrItem.Cells[2].FindControl("ddlOption") as DropDownList;
}

This works nicely, however when I try to get the selected item of the dropdownlist e.g:

ddlOption .SelectedItem.Text

It always returns the first item in the list rather than whats actually selecte din the page.
