I have a Calendar control that is bound to a Sql database.  Some days on my calendar have multiple events.  I'm able to show the dates correctly and the first event of each day but I can't figure out how to show multiple events that show up on certain dates.  Here's my code:

      private void Page_Load(object sender, System.EventArgs e)
            {
                  strConn = "data source = sqldatabase; initial catalog = database; integrated security = SSPI ";
                  conn = new SqlConnection(strConn);
                  da = new SqlDataAdapter("storedprocedure", conn);
                  da.SelectCommand.CommandType = CommandType.StoredProcedure;      
                  da.Fill(ds, "dt");
            }

            protected void CalendarDRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
            {
                  if(! e.Day.IsOtherMonth)
                  {
                        foreach (DataRow dr in ds.Tables[0].Rows)
                        {
                              if((dr["date"].ToString() != DBNull.Value.ToString()))                        
                              {
                                    String d = (String)dr["event"];
                              
                                    DateTime dtEvent=(DateTime)dr["Date"];
                                    if(dtEvent.Equals(e.Day.Date))
                                          {                              
                                                e.Cell.Text = dtEvent.Day.ToString() + d;
                                          }
                              }
                        
                        }
                  
                  }
                  else
                  {
                        e.Cell.Text = "";
            
                  }
            }

Any ideas are appreciated!

It appears as if you are using a for loop to get all the events for that date, but then your are assigning that to e.Cell.Text, and replacing it everytime with the previous event. Rather than replacing e.Cell.Text everytime, try appending the event to a list.

something like below

  if(! e.Day.IsOtherMonth)
               {
                    foreach (DataRow dr in ds.Tables[0].Rows)
                    {
                         if((dr["date"].ToString() != DBNull.Value.ToString()))                    
                         {
                              String d = (String)dr["event"];
                         
                              DateTime dtEvent=(DateTime)dr["Date"];
                              if(dtEvent.Equals(e.Day.Date))
                                   {                        
                                        YourListOfEvents.Append(dtEvent.Day.ToString() + d);
                                   }
                         }
                   
                    }
               
               }

Also, you could modify your web control to append the event.

I guess I'm not following you.  I don't think I'm looping to get all the events - maybe that's what I'm missing?

that is what your missing.. my mistake.. can you add an event count to your dataset? if so you can do something like below.. notice i added count = (Int32)dr["eventCount"];

protected void CalendarDRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
          {
               if(! e.Day.IsOtherMonth)
               {
                    foreach (DataRow dr in ds.Tables[0].Rows)
                    {
                         if((dr["date"].ToString() != DBNull.Value.ToString()))                    
                         {
                              String d = (String)dr["event"];
                              count = (Int32)dr["eventCount"];

                              DateTime dtEvent=(DateTime)dr["Date"];
                              if(dtEvent.Equals(e.Day.Date))
                                   {      
                                        for (n = 0; n < count; n++)
                                             {
                                                   e.Cell.Text = dtEvent.Day.ToString() + d;
                                             }
                                   }
                         }
                   
                    }
               
               }

I'm with you until I get to the for (n=0; n < count; n++) - what is n?

n just a local counter variable. count is the number of events, and n starts off at the first event and gets incremented n++, untill it reaches the number of events (count).

You can name it something like this..

//declare your local variables;

int numberOfEvents;
int count;

numberOfEvents = (Int32)dr["eventCount"];

//now your for loop

for(counter = 0; counter < numberOfEvents; counter ++)
