The controls refers to a function in the backend by the name of TruncateString.

Source:

<asp:TemplateField HeaderText="Desc2">

<ItemTemplate>

<asp:Label ID="Label1" runat="server" 

Text='<%# TruncateString(DataBinder.Eval(Container.DataItem,"Description").ToString()) %>'>

</asp:Label>

</ItemTemplate>

</asp:TemplateField>

Code:
Protected Function TruncateString(ByVal TheText As String) As String
        If TheText.Length > 50 Then
            Return TheText.Substring(0, 50) & " ..."
        Else
            Return TheText
        End If
    End Function

Format currency in GridView

Set the DataFormatString property of the Gridview field to:
