Create a form and add a panel to it. Say pnlW

In the code behind

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Try

        Dim tx As New TextBox
        tx.Text = "Hello"
        pnlW.Controls.Add(tx)

‘textbox added

        Dim bx As New Button
        bx.ID = "btnX"
        bx.Text = "Do something"
        bx.ToolTip = "Button does something"
        bx.CssClass = "somecssclass"
        bx.CommandArgument = "somethingunique"

‘key lines
        AddHandler bx.Command, AddressOf btnX_Click

     pnlW.Controls.Add(bx)
    Catch ex As Exception

    End Try
End Sub

Protected Sub btnX_Click(ByVal sender As System.Object, ByVal e As CommandEventArgs)
    Try
        Dim Arg As String = e.CommandArgument.ToString
        Select Case Arg
            Case Is = "somethingunique"
                Response.Write(Arg)
            Case Else

‘ other buttons..

        End Select

    Catch ex As Exception
        
    End Try
