Hi All
Run this code

SqlDataAdapter da = new SqlDataAdapter("select * from item ", con);
con.Open();
try
{
DataSet ds = new DataSet();
da.Fill(ds);
SqlCommandBuilder cb = new SqlCommandBuilder(da);

DataRow row1 = ds.Tables[0].NewRow();

row1[0] = txtaccno.Text;
row1[1] = txtname.Text;
row1[2] = txtsalary.Text;
ds.Tables[0].Rows.Add(row1);
da.Update(ds);
gvShow.DataSource = ds;
gvShow.DataBind();
