If I put the code on the same form I have the Datagridview it is working. But if the put it on another form Datagridview items is now working.

   Private Sub frmUpdateStudent_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        For i As Integer = 0 To frmRecords.DataGridView1.Rows.Count - 2
            ComboBox1.Items.Add(frmRecords.DataGridView1.Rows(i).Cells(0).Value)
        Next
    End Sub

Hi raelkun00,
You could try putting the name of your form in front of the datagridview. Like (Form2.nameof datagridview)

I already did that but it didnt work. The datagridview is on form-frmRecords and the combobox is on another form which is frmUpdateStudent. What I want is to load the first column of Datagridview to Combobox.

Ok i think i get it now. (frmRecords) is the main form and when it loads you want to send the text from its DataGridView1 to Combobox1 on the secondary form (frmUpdateStudent). If that is correct did you try it this way? The code has to be on (frmRecords) form.

frmUpdateStudent.ComboBox1.Items.Add(DataGridView1.Rows(i).Cells(0).Value)

Sorry, i guess i didn`t get it untill i looked again. If you use this in the (frmRecords) form in the event that opens (frmUpdateStudent) it should work. Make sure you are showing frmUpdateStudent with "frmUpdateStudent.Show()" and not with "frmUpdateStudent.ShowDialog()" or it will not work.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        frmUpdateStudent.Show()
        For i As Integer = 0 To DataGridView1.Rows.Count - 2
            frmUpdateStudent.ComboBox1.Items.Add(DataGridView1.Rows(i).Cells(0).Value)
        Next
    End Sub

Thanks for your reply but that doesn't work.

Oh I am sorry that works but my problem is frmRecords is an MDIChild of frmMainForm. In frmMainForm there's a button that when clicked it will load the frmUpdateStudent.Thank you so much.
