Thanks a lot for both Wajahat and Brock's informative suggestions.
Seems I've really missed such a great feature. I'll keep this in mind and
have some further investigate in the
asp.ne whidbey.
Thanks again for your contribution.

| Yes, these can be customized. They're called expression builders. I
posted
| in the past month an example, but here's another:
|
| using System.Web.Compilation;
| using System.CodeDom;
|
| public class AppSettExBld : ExpressionBuilder
| {
| public static string GetVal(string param)
| {
| return
System.Web.Configuration.WebConfigurationManager.A ppSettings[param];
| }
| public override System.CodeDom.CodeExpression
GetCodeExpression(BoundPropertyEntry
| entry, object parsedData, ExpressionBuilderContext context)
| {
| CodeMethodInvokeExpression ex = new CodeMethodInvokeExpression(new
CodeTypeReferenceExpression(typeof(AppSettExBld)),
| "GetVal", new
CodePrimitiveExpression(entry.Expression.ToString( ).Trim()));
| return ex;
| }
| }
|
|
| The method you should customize is GetVal. This sample simply reads from
| <appSettings> but you could read from a database. To configure you need
to
| modify the <compilation> section in web.config:
|
| <compilation debug="true" defaultLanguage="C#">
| <expressionBuilders>
| <add expressionPrefix="AppSet" type="AppSettExBld, __code"/>
| </expressionBuilders>
| </compilation>
|
|
| And now you can use <%$ AppSett:SomeKeyToTheGetValMethod %> in your ASPX
| pages.
