I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Sample code here to highlight the last added row.

Protected Sub Page_Load(sender As Object, e As EventArgs)
	If Not IsPostBack Then
		Dim dt As New DataTable()
		dt.Columns.Add("Name", GetType(String))

		GridView1.DataSource = dt

		ViewState("data") = dt
	End If
End Sub

Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
	If e.Row.RowType = DataControlRowType.DataRow Then
		If e.Row.Cells(0).Text = TextBox1.Text Then
			e.Row.BackColor = System.Drawing.Color.Green
		End If
	End If
End Sub

Protected Sub btnAdd_Click(sender As Object, e As EventArgs)
	Dim dt As DataTable

	If ViewState("data") Is Nothing Then
		dt = New DataTable()
		dt.Columns.Add("Name", GetType(String))
		dt = DirectCast(ViewState("data"), DataTable)
	End If

	GridView1.DataSource = dt
End Sub
