DataSet sorting

Question

In DataTable I could sorting with

 dataTable.DefaultView.Sort = "SortField DESC";

I'm getting a DataSet from database, I was wondering could I do a sorting on the DataSet like how I do it in DataTable.

Answer 1

For advanced sorting needs you might want to use LINQ like described here. Basically it allows creating a DataView from a LINQ query using the System.Data.DataTableExtensions.AsDataFiew extension method.

Alternatively if you are OK with (or maybe even prefer) using an IEnumerable you could use the System.Data.DataTableExtensions.AsEnumerable extension method. For example:

var enumerable = dataSet.Tables[0].AsEnumerable()
                 .OrderBy(x => x.Field<string>("ColumnName")
                 .ThenByDescending(x => x.Field<int?>("OtherColumnName")??0);

Answer 2

you can still access the DataTable from the the data set as follows,

ds.Tables[0].DefaultView.Sort =" criterian";

Hope this helps.
