the techinques used to take the query from the dataset..

grddata.DataBind();
}
public DataTable registertable()
{
dt = new DataTable();
dt.Columns.Add("sno");
dt.Columns.Add("name");
dt.Columns.Add("salary");
dt.Columns.Add("designation");
dt.Rows.Add("1001", "sharth", "100000", "dotnet");
dt.Rows.Add("1002", "ramesh", "40000", "java");
dt.Rows.Add("1003", "rakesh", "100000", "testing");
dt.Rows.Add("1004", "shiva", "100000", "java");
DataTable dt2 = new DataTable();
dt2 = dt.Select("salary=100000").CopyToDataTable();
ViewState["datanew"] = dt2;
grddata2.DataSource = dt;
grddata2.DataBind();
return dt2;
