C # One-time data storage in the datagridview

 namespace datatest {public partial class formmain: FORM {public formmain () {initializecomponent ();} private void button#click (Object sender, eventargs E) {mytabletableadapter. Update (mydbdataset); // save all the content here.} Private void formmain_load (Object sender, eventargs e) {// todo: This line  Code  loads data to the table "mydbdataset. mytable. You can move or remove it as needed. This. mytabletableadapter. fill (this. mydbdataset. mytable) ;}} my practice is: use dataset control, and datagridview, all are controls, the code is this private void button#click (Object sender, eventargs e) {mytabletableadapter. update (mydbdataset); // save all the content here.}
