I hav a userControl in which i hav placed 3 DropDownListBox or (these can be listboxes), for hours(0-12), Minutes(0-60) & AM/PM. & write the properties in .ascx.cs for accessing the values in my .aspx web page.

in the page load event of the user control, i hav written

if(! IsPostBack)
{
 for(int i=0;i<=12;i++)
 {
  if(i<=9)
   ddlHours.Items.Add(new ListItem("0" + i));
 else
  ddlHours.Items.Add(new ListItem(Convert.ToString(i)));
 }
}

& define the properties as follows:

public string Hours
{
get
 {
   return ddlHours.SelectedItem.ToString();
 }
}


I hav also import the UserControl's namespace, in the aspx page.

But when i m trying to access the value of the ddlHours in my page with button's click event:

DateTimePicker dtp = new DateTimePicker(); // Create object
Response.Write(dtp.Hours);

It gives an error

"Object reference not set to an instance of an object"

If u hav any solution. then pls send me.!!!!!!!

Hey,

See this: http://p2p.wrox.com/topic.asp?TOPIC_ID=45357

By the way, it's recommended not to cross-post. The admin's don't like it.
