Multiline Textbox to Datagridview - vb.net

Question

I have a multi-line textbox with this appearance:
A#B
C#
D#E
and I want to populate my datagridview to something like this:
_________
|A|BC|D|E|
I mean, I want to split when there's a "#" , but I don't want multi-line cells in datagridview.
I tried this code:
Dim sup() As String = TextBox1.Text.Split(vbCr, vbLf, vbTab, " "c, "#")
DataGridView1.Rows.Add(sup(0), sup(1), sup(2),sup(3))
but it says it goes outta bounds ... Thanks!
edit:
"Index out of range exception" Error.
If i paste the textbox values to microsoft word they come like this:

Answer 1

If you are sure you will be splitting your textbox with 3 #'s, you could use something like this after creating 3 columns in your datagridview
Dim myStr As String
Dim substring As String
Dim strArray() As String
Dim columnInt as Integer = 0
myStr = Textbox1.Text
strArray = myStr.Split("#")
For i = 0 to strArray.Length - 1
Datagridview.Rows(0).Cells(columnInt).Value = strArray(i)
columnInt += 1
next
As I am not quite sure how you want this data to appear exactly, you may also need to declare the count of your columns should it be larger than 3. Add this code before the first For Statement:
For i = 0 to strArray.Length - 1
DataGridView.Columns.Add("YourText","YourText")
Next
Untested but it should get you in the right spot!

Answer 2

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer4.Tick
If DataGridView1.RowCount = 1 Then DataGridView1.Rows.Clear()
Call dgvstuff()
Timer1.Stop()
End Sub
Sub dgvstuff()
Dim sup2 = TextBox2.Text.Replace("#", "").Replace(">", " "c)
Dim sup() = sup2.Split(" "c, "#", vbCrLf, vbTab)
With DataGridView1
.Rows(0).Cells(0).Value = sup(1).ToString
.Rows(0).Cells(1).Value = sup(7).ToString
.Rows(0).Cells(3).Value = sup(4).ToString
End With
End Sub
I really don't know why but it works like this. Anyone knows a better/cleaner way? Tks
