GridView复选框检查限制和检索数据 [英] GridView Checkbox Check Limit & Retrieve Data

问题描述

我有一个带有附加数据源的gridview

I have a gridview with an attached datasource

in a multiview; view 2. I want to make the checking done within that view 2 and transfer the contents to view 3 as summary. One of my business logic states that only a maximum number of 3 child can be selected in the gridView in view2. I would want to know which event i should be using under gridview to let this work (Checking of checkbox and saving data. After google-ing for like 1-2 hours all of the codes i've found are either not what im looking for or too complicated =.=
