What does the dollar sign $ mean in <%$ %> in the ConnectionString property for SqlDataSource control. An example is below.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:LocalDB%>" SelectCommand="SELECT * FROM TableName"></asp:SqlDataSource>
Thank you.
It’s the expression builder syntax for ASP.NET, have a look at this question for more information asp.net <%$ … %> syntax
