Answer 1

Try this...

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    DataGridView1.ColumnCount = 5
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    DataGridView1.Columns(0).Name = TextBox1.Text
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    DataGridView1.Columns(1).Name = DateTimePicker1.Value.Date
End Sub

End Class

Answer 2

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
DataGridView1.ColumnCount = 5
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)     Handles Button2.Click
'----------------Clear Recent Data on DataGridView-------------------
Try
    DataGridView1.Rows.Clear()
    DataGridView1.Columns.Clear()
Catch ex As Exception
End Try
Try
DataGridView1.DataSource = Nothing
Catch ex As Exception
End Try
'----------------Display Again Record In DataGridView-----------------------
clsTR.displayTestResults(DataGridView1, "SELECT STUDENT_NAME AS [Student Name],MONDAY AS TextBox1.Text WHERE Something something")
End Sub
End Class

WHERE STUDENT_NAME and MONDAY is the name of the database Column using "AS" will replace the database column STUDENT_NAME AS [Student Name]
