ASP.NET Concatenate AppSetting Value with DataBinder Value In Markup Page

Question

Is it possible to concatenate AppSetting value in WebConfig with DataBinder value in markup page (i.e. .aspx page - not codebehind)

This does not work:

' NavigateUrl='<%$ AppSettings:NewsPressReleasesDefaultPage %> + <%# DataBinder.Eval(Container.DataItem, "ReleaseDate") %>'>

Answer 1

Use ConfigurationManager.AppSettings:

NavigateUrl='<%# System.Configuration.ConfigurationManager.AppSettings["NewsPressReleasesDefaultPage"] + Eval("ReleaseDate").ToString() %>'>
