I dont know why my GridView.DataSource is become nothing when the Page.IsPostBack = true.What i did is bind the dataset to the GridView.DataSource when page load. Then when the button click event is trigger i need to get all the records from GridView. But when i debug and check i found that the GridView.DataSource is become nothing. Can someone tell me how should i get all records from the GridView and assign to dataset. I'm using VB.net to work on. Thanks.
