This is just an unformatted code dump. No one is going to go through this and try and figure out what it is that you are trying to do. Especially when you did not bother to explain to us what you are trying to do or what the problem is.

Do not post entire code. Please, post only those parts which is necessary to explain your issue.

Here[^] is a collection of avalible column types in the Windows Forms DataGridView. As you can see, there is nothing like numeric column.

Example:
C#
DataTable DgvDt = new DataTable();

    DataColumn dc = new DataColumn("StringColumn", Type.GetType("System.String"));
    DgvDt.Columns.Add(dc);
    dc = new DataColumn("IntegerColumn", Type.GetType("System.Int32"));
    DgvDt.Columns.Add(dc);

    dataGridView1.DataSource = DgvDt;

As you can see, second column is "numeric" column.
