datagrid has a property for sorting and paging

Answer / sunil

In a simple method,

DataSet ds = new DataSet();
// you must populate the dataset
DataTable dt = ds.tables[0];
DataView dv = new DataView(dt);
dv.Sort = dt.Columns[0];
// This will sort first column in ascending
dv.Sort = dt.Columns[0] + " DESC";
// This will sort first column in descending

OleDbDataAdapter ole=new OleDbDataAdapter(new OleDbCommand ("select * from login",oleDbConnection1)); OleDbCommandBuilder cmd=new OleDbCommandBuilder(ole); ole.Fill(dataSet11,"login"); DataRow drow=dataSet11.Tables ["login"].NewRow(); drow[0]=textBox1.Text; drow[1]=textBox2.Text; drow[2]=textBox3.Text; dataSet11.Tables["login"].Rows.Add (drow); ole.UpdateCommand=cmd.GetUpdateCommand(); ole.Update(dataSet11,"login"); MessageBox.Show("one row added"); this gives exception.how to solve it
