Hi ,

I want to sort/ order by datatable's multiple fields at a time.
LIke we do in Sql Server "Select EmpCode,EmpName,Date from Employee order Empcode,Date"

Same way i want to sort two or three columns of datatable.

I tried Datatable's dataview
as

Dim dv as New Dataview(datatbale)
dv.sort= "EmpCode,Date ASC"  -- this sorts only first column
and also
dv.sort = "EmpCode ASC,Date ASC" -- this returns an error


Please reply for the above query.



Thanks,
Tirupati Jogu

Solution 1

BindingSource BS = new BindingSource();
DataTable testTable = new DataTable();
testTable.Columns.Add("Column1", typeof(int));
testTable.Columns.Add("Column2", typeof(string));
testTable.Columns.Add("Column3", typeof(string));

testTable.Rows.Add(1, "Value1", "Test1");
testTable.Rows.Add(2, "Value2", "Test2");
testTable.Rows.Add(2, "Value2", "Test1");
testTable.Rows.Add(3, "Value3", "Test3");
testTable.Rows.Add(4, "Value4", "Test4");
testTable.Rows.Add(4, "Value4", "Test3");

DataView view = testTable.DefaultView;
view.Sort = "Column2 ASC, Column3 ASC";// Sorting Column 2 and column 3
BS.DataSource = view;

DataGridViewTextBoxColumn textColumn0 = new DataGridViewTextBoxColumn();
textColumn0.DataPropertyName = "Column1";
dataGridView1.Columns.Add(textColumn0);
textColumn0.SortMode = DataGridViewColumnSortMode.Programmatic;
textColumn0.HeaderCell.SortGlyphDirection = SortOrder.None;

DataGridViewTextBoxColumn textColumn1 = new DataGridViewTextBoxColumn();
textColumn1.DataPropertyName = "Column2";
dataGridView1.Columns.Add(textColumn1);
textColumn1.SortMode = DataGridViewColumnSortMode.Programmatic;
textColumn1.HeaderCell.SortGlyphDirection = SortOrder.Ascending;

DataGridViewTextBoxColumn textColumn2 = new DataGridViewTextBoxColumn();
textColumn2.DataPropertyName = "Column3";
dataGridView1.Columns.Add(textColumn2);
textColumn2.SortMode = DataGridViewColumnSortMode.Programmatic;
textColumn2.HeaderCell.SortGlyphDirection = SortOrder.Ascending;

dataGridView1.DataSource = BS;
