ToString("N2") and gridview

[mrp9090]

I've been working with the gridiview control for a few weeks now, and I saw some code like this :

<ItemTemplate>
<asp:Label ID="lblTarget" Text='<%# GetTarget(decimal.Parse(Eval("Target", "{0:###0.00}").ToString())).ToString("N2") %>' runat="server"></asp:Label>
</ItemTemplate>
<FooterTemplate>
<%# GetTargetTotal().ToString("N2") %>
</FooterTemplate>

What I want to know is, what does ToString("N2") mean? And why is it used?

Have you tried it and looked at what it produced?

It produces exactly what I would expect ToString() to produce.

It is a formatting string. ToString() has 4 overloaded methods.

it can be used for a numeric formatting for decimal places...

'Produces 1.000 for example, N2 would result in 1.00
checkTbNull(txtIDMM, ds.Tables(0).Rows(0).Item("IDMM"), "N3")

    Sub checkTbNull(ByVal tb As TextBox, ByVal item As Object, ByVal round As String)
        Dim tbVal As Double
        Try
            tbVal = item
            tb.Text = tbVal.ToString(round)
        Catch ex As Exception
            tb.Text = ""
        End Try
    End Sub
