How to filter out the zero value from that column?

@Kakooza-Allan-Klaus Use the above expression to get the rows which contains 0 or 0.00

If you dont want those rows contains 0 try with the below expression

dT.AsEnumerable().Where(Function(row) Information.IsNumeric(row(0).ToString)).AsEnumerable().Where(function(row) Cdbl(row(0).ToString)<>0).CopyToDataTable
