//Following function will return Distinct records for Name, City and State column.
public static DataTable GetDistinctRecords(DataTable dt, string[] Columns)
{
DataTable dtUniqRecords = new DataTable();
dtUniqRecords = dt.DefaultView.ToTable(true, Columns);
return dtUniqRecords;
}

2. Search Field

DataSet ds = new DataSet();
DataRow[] foundRows;
foundRows = ds.Tables[0].Select(“MerchantName LIKE ‘%'”, “MerchantName”);

DataTable DataTable2 = new DataTable();
DataTable2 = ds.Tables[0].Clone();
foreach (DataRow dr in foundRows)
{
DataTable2.ImportRow(dr);
}
ds.tables[0].rows.add(DataTable2); // error table already exists.
Loadimages(ds);

3. Dataset Min and Max Values

string DSMIN= (string)DS.Compute(“Min(Year)”, null);
string DSMAX= (string)DS.Compute(“Max(Year)”, null);
