There's - at least - few ways to achieve that...
1) using Linq:

C#

//returns the list of rows which meet some criteria
var resultRow = dt.AsEnumerable()
                  .Where(x => x.Field<int>("CompanyID") != hidSelectedSupplier.ClientID)
                  .ToList();</int>

2) using Filter ans Select methods:

Hi,

You should use Select() method of the DataTable object like shown below.

C#

string filterCondition = string.format(CultureInfo.CurrentCulture, "{0} = '{1}'", "CompanyName", "Test"); // assuming that you have a column called CompanyName in the DataTable and you are searching for the rows where CompanyName = "Test"

DataRow[] selectedRows = dt.Select(filterCondition);

foreach(DataRow rowItem in selectedRows)
{
    // Do your stuff
}

Please let me know if this is what you are looking for.

Thanks,
Debasis.
