Hello, I need to create a drop down list to let a user select the start time and date of an event.  I would like the current date displayed and then the time.  For example the drop down list will have selections ranging grom 7am to 11pm, with the current date in front of the time.

Can anyone help me achieve this?  I'm not sure how to code it.

Thanks

Is this a windows application or a ASP.NET application?

The code below uses System.Web.UI.WebControls.Calendar and a basic DropDownList - the dropdownlist can be made smarter as needed. Please tell me if this helps.

Try this:

<%@ Page Language="C#" AutoEventWireup="True" %>

<html>
   <script runat="server" >
 
      void Selection_Change(Object sender, EventArgs e)
      {

      // Get the selectedDate
      String selectedDate = Calendar1.SelectedDate.ToShortDateString();
      // Get the selected time
      string selectedTime = TimeList.SelectedItem.Value;
      //do processing with time and date
      // ...      
      }
   </script>
 
<body>
   <form runat="server">
      <h3> Date Time Picker </h3>
      Choose the date and time
      <br>
      <asp:Calendar id="Calendar1"
           ShowGridLines="True"
           ShowTitle="True"
           runat="server"/>
      <br>
      <table cellpadding="5">
         <tr>
            <td>
               Time:
            </td>
         </tr>
         <tr>
            <td>

               <asp:DropDownList id="TimeList"
                    AutoPostBack="True"
                    OnSelectedIndexChanged="Selection_Change"
                    runat="server">
                  <asp:ListItem Selected="True" Value="7:00 AM"> 7:00 AM </asp:ListItem>
                  <asp:ListItem Value="8:00 AM"> 8:00 AM </asp:ListItem>
                  <asp:ListItem Value="9:00 AM"> 9:00 AM </asp:ListItem>
                  <asp:ListItem Value="10:00 AM"> 10:00 AM </asp:ListItem>
                  <asp:ListItem Value="11:00 AM"> 11:00 AM </asp:ListItem>
                  <asp:ListItem Value="12:00 AM"> 12:00 AM </asp:ListItem>
                  <asp:ListItem Value="1:00 PM"> 1:00 PM </asp:ListItem>
               </asp:DropDownList>

            </td>
        </tr>
     </form>
</body>
</html>

this does not add the currnt date to the drop down list.  I need the drop down list to display current date then the time.

example ( each line would be a selection in the drop down list)

10/14/2004 7:00am
10/14/2004 7:30am

and so on

Add this function to the Load event of the dropdown list:

private void TimeList_Load(object sender, System.EventArgs e)
{
     //TimeList is the drop down list
      TimeList.Items.Clear;
      //populate array of times - put in all relevant values
      string[] timeArrList = {" 7:00 AM"," 7:30 AM "," 8:00 AM "};
      string currDate = Calendar1.SelectedDate.ToShortDateString();
      for(int i=0;i<timeArrList.Length;i++)
      {
      timeArrList[i] = currDate + timeArrList[i];
      TimeList.Items.Add(timeArrList[i]
      }
}

This will show items in the drop down the way you want. Change the format of the date if you need to show it differently.

Small coding error  - missing bracket and ;

private void TimeList_Load(object sender, System.EventArgs e)
{
   TimeList.Items.Clear;
   string[] timeArrList = {" 7:00 AM"," 7:30 AM "," 8:00 AM "};
   string currDate = Calendar1.SelectedDate.ToShortDateString();
   for(int i=0;i<timeArrList.Length;i++)
  {
      timeArrList[i] = currDate + timeArrList[i];
      TimeList.Items.Add(timeArrList[i]);
   }
}

The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value. The statement has been terminated
