How do i set the calendar dates unselectable accordingly to the name in the DropDownList the users select?

In other words, each name in the DropDownList will have different unselectable dates set and i tried to use the following codes to execute my program but it seems to be not working.

How do i do so?

C#

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (DropDownList1.SelectedItem.Text == "WeddingPlanner1")
    {
        if (e.Day.Date.Month == 7 || e.Day.Date.Month == 9 || e.Day.Date.Month == 12)
    {

        if (e.Day.Date.Day == 5 || e.Day.Date.Day == 14 || e.Day.Date.Day == 18)
        {
            e.Day.IsSelectable = false;
            e.Cell.ForeColor = System.Drawing.Color.Black;
            e.Cell.BackColor = System.Drawing.Color.White;
            e.Cell.Font.Bold = true;
        }
    }
}

set AutoPostBack true for DropDownList1

C#

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" >

after that, move your code in to Day render event of your calendar control

C#

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
    if (DropDownList1.SelectedItem.Text == "WeddingPlanner1")
    {
        if (e.Day.Date.Month == 7 || e.Day.Date.Month == 9 || e.Day.Date.Month == 12)
        {

            if (e.Day.Date.Day == 5 || e.Day.Date.Day == 14 || e.Day.Date.Day == 18)
            {
                e.Day.IsSelectable = false;
                e.Cell.ForeColor = System.Drawing.Color.Black;
                e.Cell.BackColor = System.Drawing.Color.White;
                e.Cell.Font.Bold = true;
            }
        }
    }
}

You know how to add above event?

go to properties of your calendar control and then go to events tab and find the DayRender and double click on it.
