How to merge multiple dataviews into one?
I have three dataviews (dataview1, dataview2, and dataview3). These are of type System.Data.DataView, and all three have the same columns. Is there an easy way to merge them into one, so I have one datavie开发者_运维百科w with rows from dataview1, followed by dataview2, and then dataview3?
Dim dataview1 As DataView = new DataView()
Dim dataview2 As DataView = new DataView()
'' given the tables are not null you can then merge like this
dataview1.Table.Merge(dataview2.Table)
DataTable datatableMerge = dataview1.ToTable();
datatableMerge.Merge(dataview2.ToTable());
The result includes only the rows according to the the DataViews' Filters.
