Hi Alan,
Yeah, it's a difficult problem, because the functionality is embedded in User Controls. To promote reuse, you can't strongly couple the controls. So, although you technically could, you shouldn't find a reference in control A to control B and call some method.
Instead, you should base this on Events. The BlogEntry control should fire an Event called OnBlogEntrySaved (or whatever you want to call it). The containing page handles this event (similar to how it handles a Button's click) and then calls RefreshGridView on the other user control.
For an implementation of this, look at the WebShop chapter. The ShoppingCartView.ascx control defines an event called CartUpdated that is used to signal other parts of the application that the shopping cart has changed.
However, if you want to do this much and much simpler, simply redirect to:
Response.Redirect(Request.CurrentExecutionFilePath )
In addition, to preserve the querystring, look at GetNavigateUrl in the BlogEntriesFilter control.
Hope this helps,
Imar
