So my final goal is to take some columns from one form's datagridview (in form3) and place them into a seperate form's datagridview (form4). I started off by just trying to put all of the rows in there one-by-one. Later I will be moe picky about which rows I want. Below is the code I am using. The problem is that I am ending up with an empty form, but no errors. Thank you for your input.




Code:

VB.NET:
Public Class Form4
    Inherits System.Windows.Forms.Form
    Dim frmInstance As New Form3()

    Public Sub Populate_A1_Data()
        Try
            With Me.DataGridViewA1
                .Rows.Clear()
                Dim ColumnCount2 As Integer = frmInstance.DataGridView1.ColumnCount
                'MessageBox.Show(ColumnCount2) ' test to see if i counted the columns
                For i As Integer = 0 To ColumnCount2 - 1
                    .Columns.Add(frmInstance.DataGridView1.Columns(i).Name, frmInstance.DataGridView1.Columns(i).Name)
                Next
                .AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.ColumnHeader
                Dim RowCount As Integer = frmInstance.DataGridView1.RowCount
                For i As Integer = 0 To RowCount - 1
                    Dim objCells1 As DataGridViewRow = frmInstance.DataGridView1.Rows(i).Clone

                    .Rows.Add(objCells1)
                Next
            End With
        Catch ex As Exception
            MessageBox.Show("Error: " & ex.Message)
        End Try
    End Sub
