Huh?
You have a Dipti_Calendar defined in your ASP.NET code for the Default.aspx page:

Expand|Select|Wrap|Line Numbers

 
<DiptiCalendar:Dipti_Calendar ID="DC" runat="server" OnDayRender="DC_DayRender" TitleStyle-CssClass="month_cont" DayHeaderStyle-CssClass="weekname_cont" > 

</DiptiCalendar:Dipti_Calendar>

But I don't see you using that control in your C#, server-side code....

Have you tried something like:

Expand|Select|Wrap|Line Numbers

 
protected void Page_Load(object sender, EventArgs e)

{

  DC.h_color = Color.Pink;

}

I really don't understand where the problem is...

You need to use using public properties in your Dipti_Calendar to expose things that you require in your ASPX page to do what you need to do.

For example, your Dipti_Calendar control should contain a public "Date" property so that you can access the selected date in the Button Click event code that is part of your ASPX page....this way you can call your stored procedure and pass it the appropriate value as the date parameter. You will also need to have a "CalendarValue" property that will give you access to the information that should be provided to your stored procedure as the value parameter.

As for your second question....

You should probably not be adding controls dynamically to your page unless you fully understand what is entailed with this process.

Instead you should just open the Dipti_Calendar.aspx file and add the controls where every you want them to be.
