Front Controller / IHttpModule

[moid]

Sir we are implementing front controller in asp.net.
we implement three event-handler
1. PreRequestHandlerExecute
2. PostRequestHandlerExecute
3. BeginRequest

we just want to initialize the page, but dont want to load it.
After BeginReq the page should Load.

becuse we need to fill Datagrid through Command
and then load it.

is there any event in httpmodule that initialises page init events
or is there some thing we are missing in whole here
please help me.

Thanks and Regards.
Moid

Try
Dim command As Command = CommandFactory.Make(context.Request.RawUrl)
If Not (command Is Nothing) Then
command.Execute(context)
Else
