Command Execution

[Niggy]

I think I'm missing an execute command here. Please help.

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Me.Label1.Text = ListBox1.SelectedItem.Value()
Me.DataGrid1.Visible = False
Me.MySqlCommand2.CommandText = "select * from filename where
Customer_id=" + ListBox1.SelectedItem.Value
Me.MySqlDataTable2.SelectCommand = Me.MySqlCommand2
Me.DataSet11.Reset()
Me.MySqlDataAdapter2.Fill(DataSet11)
DataGrid1.DataSource = DataSet11
DataGrid1.DataBind()
Me.DataGrid1.Visible = True
End Sub

..NET 2.0, I assume?

Since you are not using one of the new DataSource objects, I would venture
that you need to open the connection before the Fill() and then close it.

Thanks. I've done as you suggest, however, I still need to execute the
command text. How do I do this within the context of my existing code?

My code so far is:

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Me.Label1.Text = ListBox1.SelectedItem.Value()
Me.DataGrid1.Visible = False
Me.MySqlCommand2.CommandText = "select * from filename where
Customer_id=" + ListBox1.SelectedItem.Value
Me.MySqlDataTable2.SelectCommand = Me.MySqlCommand2
Me.DataSet11.Reset()
Me.MySqlDataAdapter2.Fill(DataSet11)
DataGrid1.DataSource = DataSet11
' DataGrid1.DataBind()
Me.DataGrid1.Visible = True
End Sub

But my datagrid remains the same. Any ideas?

The correct code is:

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim Cust_id As String
Cust_id = "select * from filename where Customer_id=" +
ListBox1.SelectedItem.Value()
Me.DataGrid1.Visible = False
Me.MySqlConnection1.Open()
Me.MySqlCommand1.CommandText = Cust_id
Me.MySqlDataTable1.SelectCommand = Me.MySqlCommand1
Me.MySqlDataAdapter1.Fill(DataSet11)
Me.MySqlConnection1.Close()
DataGrid1.DataSource = DataSet11
DataGrid1.DataBind()
Me.DataGrid1.Visible = True
End Sub
