将所有数据从DataGridView的一种形式传递到另一种vb.net

Question

所以我试图将DataGridView上的所有行从一个按钮单击传递到另一种形式。 从frm_1.vb中的grd_order到frm_2.vb中的grd_invoice

因为我是vb.net的新手，所以这是我所能做的

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

尝试这个

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

希望这可以帮助。

Answer 2

最简单的方法是将第一个DataGridView的DataSource传递给第二个。

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

您还可以将Data属性定义为DataTable ，并将您在第一个表单上拥有的数据表传递给第二个表单。
