How to get Values from Dynamic generated Textbox

[musicazx]

I'm new to Visual Basic.
I have a little program look like this.
https://www.dropbox.com/s/xr44pxp3n79atkk/wall.png <Please have a look

It will calculate the total area by adding up all wall area.

 Public Sub btnWallAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWallAdd.Click
        FlowLayoutPanel1.Controls.Clear()
        FlowLayoutPanel1.AutoScroll = True

        For i As Integer = 1 To Val(txtWallNo.Text)
            Dim Width As New TextBox()
            Dim Height As New TextBox()

            Width.Name = "Width" & i
            Width.Text = Width.Name
            Height.Name = "Height" & i
            Height.Text = Height.Name

            FlowLayoutPanel1.Controls.Add(Width)
            FlowLayoutPanel1.Controls.Add(Height)

        Next
    End Sub

Been a long time since I touched VB.Net,

A quick google showed the following as a way to do it, however I have not confirmed this myself.

TabPage.Controls.Find("ControlName", true)

Where the true options also searches child controls.
