i tried to customize the column name because the column name in my datagridview comes directly from the table column name, which is kindda odd. i browse throught this forum and other forums on howto's but i get this wierd error.

Dim dgTS As New DataGridTableStyle
        Dim ColStyle As New DataGridTextBoxColumn

        ColStyle.MappingName = "empID"
        ColStyle.HeaderText = "Employee ID"

        DataGridView1.TableStyles.Add(dgTS) 'error here, green underline

tablestyles is not a member of system.windows.form.datadridview do i have to add additinal reference to my project?

please help..

You're mixing DataGrid with DataGridView.
DataGridView does not have a .TableStyles property

how do i give a custom column to my datagridview then? please advice

Here is a technique:

Public Class Form1

   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

      DataGridView1.Columns.Add("asdf", "myASDF")
      DataGridView1.Columns(0).Width = 444

      For i As Integer = 0 To 3
         DataGridView1.Rows(i).Cells(0).Value = "adsf"

      Dim style As New DataGridViewCellStyle With {.ForeColor = Color.Red}

      DataGridView1.Rows(0).Cells(0).Style = style
      DataGridView1.Rows(2).Cells(0).Style = style
   End Sub
End Class

Error: Rows cannot be add programatically When control is databound??
besides this adds new column, what i want is to rename the data table field name.
orderID(field name) to Order ID(custom)

Modify the style before binding the data.

Finally get the solution. For anyone who have this problem, the solution is simple.

myDataTable.Columns(0).Name = "Name of the first column"

This change the default database field/column names.
