How do I load a datagridview on a from from another form?

I have a form that contains a datagridview.  The user can manually load the datagridview or they can click a button that will launch another form that will browse for a file, read the data from the file and post it to the datagridview on the original form.  Within the button_click event on Form2 I have tried to add rows to the datagridview on Form1 to no avail.  I have stepped through the code on Form2 and it is executing the DataGridView1.Rows.Add statement but nothing appears in the datagridview when Form2 closes.  Any thoughts?

can we have a look atyour code? There may be something that may seem correct to you BUT turn out to be wrong. Otherwise, the code logic you describe above SHOULD do what you want.

Hi,

How are you accessing the Datagridview in form1?

I assume that in your form1 you are calling the form2, so you can pass it the instance of form1 so you can access the datagridview, something like this

Dim f2 as New Form2
f2.Owner = Me 'Here you are passing the instance of Form1 to Form2
f2.ShowDialog

Inside the Form2 button_event you use the Owner property to get the instance of the Form1

dim f1 as form = Ctype(Me.Owner, form1)

And to access the Datagridview

f1.Datagridview1.Rows.Add(yourrow)

Hope that helps

I'm getting a "dgvGreigeGoodsRolls is not a member of System.Windows.Forms.Form" build error on the ".Rows.Add" statement.

'Form 1 Button_Event
        Dim frmOrderEntryGreigeGoodsImport As New Order_Entry_GreigeGoods_Import
        frmOrderEntryGreigeGoodsImport.Owner = Me
        frmOrderEntryGreigeGoodsImport.ShowDialog()

'Form 2 Button_Event
        Dim strReadBuffer As String
        Dim intGreigeGoodsRollNumber As Integer
        Dim intTotalYards As Integer
        Dim frmOrderEntryGreigeGoods As Form = CType(Me.Owner, Order_Entry_GreigeGoods)
        FileOpen(1, "..\Imports\GreigeRolls.txt", OpenMode.Input, OpenAccess.Read, OpenShare.Shared)
        While Not EOF(1)
            strReadBuffer = LineInput(1)
            frmOrderEntryGreigeGoods.dgvGreigeGoodsRolls.Rows.Add(intGreigeGoodsRollNumber, Mid(strReadBuffer, 12, 9), dReader1("ConstructionID"), "", Mid(strReadBuffer, 22, 4), Mid(strReadBuffer, 29, 4), 0, CInt(Mid(strReadBuffer, 36, 4)))

Ok, change this line

Dim frmOrderEntryGreigeGoods As Form = CType(Me.Owner, Order_Entry_GreigeGoods)

For this one

Dim frmOrderEntryGreigeGoods As Order_Entry_GreigeGoods = CType(Me.Owner, Order_Entry_GreigeGoods)

Also the dgvGreigeGoodsRolls in Order_Entry_GreigeGoods should have set the MODIFIERS property to PUBLIC
