Clearing CGridView filters and sort orders from the web pages, is usefull for the end user. Yii does not seem to propose a standard method. Furthermore, this is especially usefull when filters are "remembered" in the user's session.

I assume you are familiar with accessControl standard filter. It allows you to separate privileges to run some action from action code itself. There is however one problem with most common usage - you cannot use bizRules, at least based on some parameters passed to 'checkAccess' just because it is hard to pass them in accessRules() result.
A big problem I've hit with the Yii-Bootstrap extension is that all AJAX requests are initializing Bootstrap because of preload. This is a huge waste of resources, especially when using AJAX-based file uploaders that split the file into chunks. Large file uploads using that method could be initializing bootstrap hundreds of times.
CGridView (or CListView) together with CActiveDataProvider is a very powerful combination of the built-in tools of Yii. But how do they work together to accomplish their fantastic functions? And what are you expected to do to use them and to customize their behaviors? This article explains the very basics of them.
In SQL, wildcard characters can be used in "LIKE" expressions; the percent sign (%) matches zero or more characters, and underscore (_) a single character. Sometimes users are not familiar with these or they are using different ones like (*) and (+) similar to regular expressions. My colleages do so and then i decided to add this feature by extending CbCriteria. Especially adding a new parameter $...
class Post extends CActiveRecord {
...
}
`
When you list Authors in grid you would like to print the count of posts in column, allow sorting on this column and probably filtering by the count.
We can use a CJuiDatePicker for a CGridView inline filter.
You can find the reason why I wrote this article here.
Using filters on CGridView with CActiveDataProvider is easy, but with CArrayDataProvider it is a bit tricky.
This is what I did. Its the EASIEST solution that I know of. I just reused the advanced search done in CGridView.
I ran into a problem and on irc we worked it out. Since there is a lack on information on filters in genral i thought i'd start sharing all my findings, might be usefull for other people.
