Tiny drips of Asp.Net juice

long time no see,

I've been a busy little bee working on a fairly large web site for online gambling (horse races), with some SERIOUSLY cool software/frameworks. Going from the outside in it's been jQuery, EPiServer 5, Asp.Net 3.5, WCF, SOA, NHibernate. And I have learned more from this project than any other. I'm going to publish reference code (for my own later googling pleasure) from this project for quite a while I reckon. I'm starting easy with some webcontrols we have used throughout the solution. using our own has made it possible to enable/utilize jQuery very easily.

to ensure the ID of controls are fixed, we have used this little trick:

public class ClientIdHiddenField: HiddenField

{

public override string ClientID{ get{ return ID; } }

}


This enables us to be certain that the jQuery selectors all work as expected

similarly we have overridden labels/buttons/etc to enable us to give the webcontrols a TextKey property (e.g. TextKey="/app/game/gamewindow/buygame" ) declaratively, the TextKey is then used to lookup the correct text from the Translate function in EPiServer


public class TranslateButton: Button

{

[DefaultValue("")]

public string TextKey{ get; set; }

protected override void OnPreRender(EventArgs e)

{

if (!string.IsNullOrEmpty(TextKey) && string.IsNullOrEmpty(Text))

{

Text = LanguageUtil.TranslateOrBlank(TextKey);

}

base.OnPreRender(e);

}

}



As these are all just Custom Controls (no code-front file) we can specify their namespace in web.config:


[pages validateRequest="false" enableEventValidation="false"]

[controls]

...........

[add tagPrefix="cc" namespace="OurNamespace.CommonUC" assembly="OurAssemblies.Web" /]

[controls]

[pages]


(couldn't get < to work properly in markup here ...)
