How can i get the sum from datagridveiw column

[Joe_28]

I have a datagridveiw with 6 differnet columns. I got 2 columns with the header names, "In" and "Out".

So my question is, how can i get the sum of each showing in a seperate textbox. Not by the # of columns there are but by the name of the header?
Example:

Textbox1.text= the sum of the column named "In"

Textbox2.text= the sum of the column named "Out"

Go through the rows , pick and add your desired cell values.

Dim x As Double = 0.0#
Dim y As Double = 0.0#

For i As Integer = 0 To DataGridView1.Rows.Count - 1
    x += CDbl(DataGridView1.Rows(i).Cells(4).Value)
    y += CDbl(DataGridView1.Rows(i).Cells(5).Value)
Next

TextBox1.Text = x
TextBox2.Text = y
