问题 I'm using checkbox to select the rows in the gridview. How do I insert the muliple selected rows into the table opening the connection for only one time. 回答1: When you postback, read all the checked rows and put the data into a DataTable . You can then use a SqlBulkCopy object to push that DataTable into your database table. 回答2: Using JS to write into hidden field when user (un)checks a checkbox or to perform ajax call to server with id checked row. 来源： https://stackoverflow.com/questions
