Codes in DataGridView form

Public Class Form3

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Close()
        Form1.Show()
    End Sub

    

    Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'DataDataSet.STORE' table. You can move, or remove it, as needed.
        Me.STORETableAdapter.Fill(Me.DataDataSet.STORE)

    End Sub

    
   
End Class
