{
    //
}

why don't you just loop through your datasource ? – G-Man Oct 06 '12 at 17:28 — G-Man, Oct 06 '12 at 17:28

@just_name, you need to remember that any manipulation with server-side objects like GridViewRow is worst way to work with data. If you need any data-driven manipulations - do it in source of data, not with view.

@just_name you can't use binding to bind textbox values to model in source? Can you describe full problem, mb there are better way to solve it? – DrAlligieri Oct 07 '12 at 22:20

You can use Cast<T> or OfType<T> to convert to IEnumerable<T>:

foreach (GridViewRow oItem in GridView1.Rows.OfType<GridViewRow>())
{
}

Or:

foreach (GridViewRow oItem in GridView1.Rows.Cast<GridViewRow>())
{
}

In this case it is correct to use both because Rows only contains element of GridViewRow. But you should not notice the different between two methods:

Cast<T>: Casts the elements to the specified type.
OfType<T>: Filters the elements based on a specified type.
