The Textbox control and the date picker can work together. When selecting a date from the Calendar, the text box will be populated with that specific date.

<obout:OboutTextBox runat="server" ID="txt1" />

<obout:Calendar ID="cal1" runat="server" DatePickerMode="true" />

protected void Page_Load(object sender, EventArgs e)
{
    cal1.TextBoxId = txt1.ClientID;
}

Protected Sub Page_Load(By Val sender As Object, ByVal e As EventArgs)
    cal1.TextBoxId = txt1.ClientID
End Sub
