The below code is for Row filter from Dataview and the result converted in DataTable

                itemCondView.RowFilter = "DeliveryNumber = '1001'";
                dataSet = new DataSet();
                dataSet.Tables.Add(itemCondView.ToTable());

The answer does not work for my situation because I have columns with expressions. DataView.ToTable() will only copy the values, not the expressions.

First I tried this:

//clone the source table
DataTable filtered = dt.Clone();

//fill the clone with the filtered rows
foreach (DataRowView drv in dt.DefaultView)
{
    filtered.Rows.Add(drv.Row.ItemArray);
}
dt = filtered;

but that solution was very slow, even for just 1000 rows.

The solution that worked for me is:

//create a DataTable from the filtered DataView
DataTable filtered = dt.DefaultView.ToTable();

//loop through the columns of the source table and copy the expression to the new table
foreach (DataColumn dc in dt.Columns) 
{
    if (dc.Expression != "")
    {
        filtered.Columns[dc.ColumnName].Expression = dc.Expression;
    }
}
dt = filtered;

You can use 

   if (datavw.Count > 0)             
   {                 
     DT = datavw.ToTable(); // This will copy dataview's RowFilterd values to datatable              
   }

You can use DateView.ToTable() for converting the filtered dataview in to a datatable. 

DataTable DTb = new DataTable();
DTb = SortView.ToTable();
