[RESOLVED] Calling MDI Child Sub

Hi

I have a MDIParent Form named "frm_discipulus.vb" which opens a MDIChild Form named "frm_gestionare_cursanti.vb"

Code:

---

    Private Sub tsm_cursanti_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsm_cursanti.Click

        Me.Cursor = Cursors.WaitCursor

        Dim frm_mdi_gestionare_cursanti As New frm_gestionare_cursanti
        frm_mdi_gestionare_cursanti.MdiParent = Me
        frm_mdi_gestionare_cursanti.Show()
        frm_mdi_gestionare_cursanti.txt_cautare_cursanti.Select()
        frm_mdi_gestionare_cursanti.txt_cautare_cursanti.Focus()

        Me.Cursor = Cursors.Arrow

    End Sub

---

On MDIChild "frm_mdi_gestionare_cursanti" i have:

1. A DataGridView named "dgv_note" populated by the Public Sub named "afisare_note_obtinute"

Code:

---

Public Sub afisare_note_obtinute()

        Try

            conectare_db()

            data_table = New DataTable
            data_adapter = New SqlClient.SqlDataAdapter("SELECT lista_note_obtinute.id, nomenclator_discipline.denumire_disciplina, lista_note_obtinute.id_clasa, lista_note_obtinute.nota_obtinuta, lista_note_obtinute.id_cursant, lista_note_obtinute.data_notei FROM lista_note_obtinute, nomenclator_discipline WHERE lista_note_obtinute.id_disciplina = nomenclator_discipline.id AND lista_note_obtinute.id_cursant='" & Me.dgv_lista_cursanti.CurrentRow.Cells(0).Value & "' AND lista_note_obtinute.id_clasa='" & Me.dgv_clase.CurrentRow.Cells(1).Value & "' ORDER BY nomenclator_discipline.denumire_disciplina;".ToString, conexiune)

            command_builder = New SqlClient.SqlCommandBuilder(data_adapter)
            data_adapter.Fill(data_table)
            Me.dgv_note.DataSource = data_table

            Dim coloana_1 As DataGridViewColumn = dgv_note.Columns(1)

            Me.dgv_note.Columns(0).Visible = False
            Me.dgv_note.Columns(1).HeaderText = "Disciplină"
            Me.dgv_note.Columns(2).Visible = False
            Me.dgv_note.Columns(3).Width = 90
            Me.dgv_note.Columns(3).HeaderText = "Notă"
            Me.dgv_note.Columns(4).Visible = False
            Me.dgv_note.Columns(5).Width = 90
            Me.dgv_note.Columns(5).HeaderText = "Din data"

            coloana_1.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill

            deconectare_db()

        Catch ex As Exception
        End Try

    End Sub

---

2. LinkLabel named "lkl_adaugare_nota" which opens a Form named "frm_adaugare_nota_cursant"

Code:

---

    Private Sub lkl_adaugare_nota_LinkClicked(sender As System.Object, e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles lkl_adaugare_nota.LinkClicked

        frm_adaugare_nota_cursant.ShowDialog()

    End Sub

---

On that form (frm_adaugare_nota_cursant) users had to input some datas and after it's finishing and closing the form the data must be visible on MDIChild DataGridView.

I have tried to call the "Public Sub frm_gestionare_cursanti()" by using the code

Code:

---

frm_gestionare_cursanti.afisare_note_obtinute()

---

And nothing hapends.

Why ?
What shold i do to refresh the DGV on MDIChild?

don't call it from you other form... call it from the LinkClicked event:

Code:

---

    Private Sub lkl_adaugare_nota_LinkClicked(sender As System.Object, e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles lkl_adaugare_nota.LinkClicked

        frm_adaugare_nota_cursant.ShowDialog()
        afisare_note_obtinute()

    End Sub
