How to use inserttemplate in gridview.

DataTable dt = new DataTable();

get data and assign dt from database Then write below code

Gv.DataSource = dt;
Gv.DataBind();

I assumed dt is having two columns EmployeeId,EmployeeName.

In button click you need to write below code

dt.Rows.Add(0,"Jagssidurala");
Gv.DataSource = dt;
Gv.DataBind();
