Vb.net datagridview Column

Hi,

I`d like to add a column named "C" to my datagridview which will be the sum of each row in columns "A" and "B",

Like this :

column A  Column B   Column C
2                 5                  7

How would I add this column to my datagridview?

Thank you

You surely have a datatable behind your datagid? add a calculated column to your datatable as shown in https://msdn.microsoft.com/en-us/library/vstudio/zwxk25bd(v=vs.100).aspx?cs-save-lang=1&cs-lang=vb#code-snippet-1

I'm importing the data from excel into a dataset :

     Dim MyConnection As System.Data.OleDb.OleDbConnection
        Dim DtSet As System.Data.DataSet
        Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
        MyConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source='S:\Cms\EnviroMap.xls';Extended Properties=Excel 12.0 Xml")
        MyCommand = New System.Data.OleDb.OleDbDataAdapter("select * from [enviroMap$]", MyConnection)
        MyCommand.TableMappings.Add("Table", "Net-informations.com")
        DtSet = New System.Data.DataSet
        MyCommand.Fill(DtSet)
        DataGridView1.DataSource = DtSet.Tables(0)
        MyConnection.Close()

Open in new window

So you have a datatable:

MyCommand.Fill(DtSet)
DtSet.Tables(0).Columns.Add("SalesTax", Type.GetType("System.Double"),   "A + B)
DataGridView1.DataSource = DtSet.Tables(0)
