将所有数据从DataGridView的一种形式传递到另一种vb.net

Question

So i am trying to pass all rows from a DataGridView on a Button Click from one form to another. Which is from grd_order in frm_1.vb to grd_invoice in frm_2.vb

This is as far as i can go since i am stil new to vb.net

frm_1.vb

Private Sub btn_purchase_Click(sender As System.Object, e As System.EventArgs) Handles btn_purchase.Click
      Dim newForm As New frm_2
      newForm.AllRows = grd_order.DataSource
      'what should i put here because the above line is wrong
      newForm.Show()
End Sub

frm_2.vb

Public Class frm_2
      Public Property AllRows As DataGridViewSelectedRowCollection
      'I know that DataGridViewSelectedRowCollection is used for the specific row but what about all rows?

      Private Sub frm_2_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
      'grd_invoice.DataSource = PassText
      'what should i put here
      End Sub
End Class

Answer 1

try this

Private Sub btn_purchase_Click(sender As System.Object, e As System.EventArgs) Handles btn_purchase.Click
      Dim newForm As New frm_2
      For Each col As DataGridViewColumn In grd_order.Columns
        newform.grd_invoice.Columns.Add(col)
      Next
      For Each row as DataGridViewRow in grd_order.rows

       newForm.grd_invoice.Rows.Add(row)

      next
     newForm.Show()
End Sub

hope this helps.

Answer 2

The most simple way would be passing the DataSource of your first DataGridView to second one.

Public Class frm_customer_invoice_a153834
    Public Property Data As Object

    Private Sub Form_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Me.grd_invoice.DataSource = Data
    End Sub
End Class

You can also define the Data property as DataTable and pass the data table that you have on your first form, to the second form.
