extjs - Query for child component with a specific xtype -

-

Is there a method for querying a child component of xtype 'myxtype'? For example, you have a panel, and there is a custom proxy located on a toolbar inside this panel.

The searcher works great to type backups, but there is no method like FindBildType and the method below only works on the elements Ext.ComponentQuery is a singleton, but not for xtypes? Another way to ask about the component?

yourCt.down

yourCt .child will do the same, but is limited to children directly, the first example of a container with the specified type of component children and lineage will be found. Container.

yourCt.query will be all of matching components under the container as an array.

yourCt.up will be available to the guardian before the matching container.

Oh, and Ext.ComponentQuery.query can move an optional object that is used as the starting point for the query.

These are all basic (and clearly documented)

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
