Design a window application that will create datacolumn in code (on btn click) at runtime.

CODE:

Imports System.Data

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim tb As New DataTable("stud")

Dim col As DataColumn

col = New DataColumn

col.DataType = GetType(Int32)

col.ColumnName = "id"

tb.Columns.Add(col)

col = New DataColumn

col.DataType = GetType(String)

col.ColumnName = "name"

tb.Columns.Add(col)

DataGridView1.DataSource = tb

End Sub

End Class
