问题 I have a gridview to which I have created an Insert Template in the footer row. I have an ObjectDataSource which is bound to a business object.

问题 What is the correct way to do a row by row css expression. In Yii 1 is was rowCssClass. I couldn't figure out how to achieve this with Yii2. I had tried this, but wasn't sure I was on the right lines: 'rowOptions' => function($model, $key, $index, $grid){ if($data->option->correct_answer == 1){ return ['class' => 'danger']; } }, I'm unsure where to get the parameters for the function from when dealing with the dataProvider though. 回答1: Use $model instead $data.

问题 I used the following piece of code in the web.config in order to maintain the scrollbar position after a server postback: <pages maintainScrollPositionOnPostBack="true" > </pages> All is working fine, but now i have a gridview encapsuled within a div with a scrollbar in the div (internal scrollbar).
