How to sort a DataGridView Column?

Question

I\'ve created a DataTable as follows:

        accTable = new DataTable();
        accTable.Columns.Add(new DataColumn(\"Date\"));
        accTable.Columns.Ad         


        

Answer 1

The column has a DataType. Have you tried setting that to DateTime?

var accTable = new DataTable();

var columnSpec = new DataColumn("Date");
columnSpec.DataType = typeof(DateTime);
accTable.Columns.Add(columnSpec);

Of course you can do this on one line (thanks to BFree):

accTable.Columns.Add("Date",typeof(DateTime));

You bind this DataTable to a DataGridView and then for each column on the view set the SortMode property:

column.SortMode = DataGridViewColumnSortMode.Automatic;

I did have some code that did all this, but I converted it to use nullable types (including the DateTime fields) and it's not working as I expected any more. If I can get it working properly again I'll update this answer.

Answer 2

For date data, we can use the following code:

dgv_transfer_from.Sort(dgv_transfer_from.Columns["Date_Out"], ListSortDirection.Ascending);
