[.net] Sorting a Data Table

I tried to sort a data table with following two ways

table.DefaultView.Sort = "Town ASC, Cutomer ASC"

table.Select("", "Town ASC, Cutomer ASC")

But none of them wasn't worked. It always displays data in original order. Do you have any idea to solve the problem.

private void SortDataTable(DataTable dt, string sort)
{
DataTable newDT = dt.Clone();
int rowCount = dt.Rows.Count;

DataRow[] foundRows = dt.Select(null, sort);
// Sort with Column name
for (int i = 0; i < rowCount; i++)
{
object[] arr = new object[dt.Columns.Count];
for (int j = 0; j < dt.Columns.Count; j++)
{
arr[j] = foundRows[i][j];
}
DataRow data_row = newDT.NewRow();
data_row.ItemArray = arr;
newDT.Rows.Add(data_row);
}

//clear the incoming dt
dt.Rows.Clear();

for (int i = 0; i < newDT.Rows.Count; i++)
{
object[] arr = new object[dt.Columns.Count];
for (int j = 0; j < dt.Columns.Count; j++)
{
arr[j] = newDT.Rows[i][j];
}

DataRow data_row = dt.NewRow();
data_row.ItemArray = arr;
dt.Rows.Add(data_row);
}
}

This worked for me:

dt.DefaultView.Sort = "Town ASC, Cutomer ASC";
dt = dt.DefaultView.ToTable();

Try this:

Dim dataView As New DataView(table)
dataView.Sort = " AutoID DESC, Name DESC"
Dim dataTable AS DataTable = dataView.ToTable()

This was the shortest way I could find to sort a DataTable without having to create any new variables.

DataTable.DefaultView.Sort = "ColumnName ASC"
DataTable = DataTable.DefaultView.ToTable

Where:

ASC - Ascending

DESC - Descending

ColumnName - The column you want to sort by

DataTable - The table you want to sort
