How to populate the date present in the database table to Calender asp.net? - asp.net

Question

My table in the database has the following columns id , eventstart , eventend , eventname
I am trying to bind the event name plus the event start date in the cell of the calender on the date which it is occurring
However i am not able to do so
Following is my code snippet
protected void myCal_DayRender1(object sender, DayRenderEventArgs e)
{
DataSet ds = new DataSet();
SqlDataAdapter cmd = new SqlDataAdapter("Select * FROM event", con);
cmd.Fill(ds, "Table");
if (!e.Day.IsOtherMonth)
{
foreach (DataRow dr in ds.Tables[0].Rows)
{
if ((dr["eventstart"].ToString() != DBNull.Value.ToString()))
{
DateTime dtEvent = (DateTime)dr["eventstart"];
if (dtEvent.Equals(e.Day.Date))
{
Label lbl = new Label();
lbl.BorderColor = System.Drawing.Color.Black;
lbl.BorderStyle = BorderStyle.Double;
lbl.Width = 100;
lbl.Height = 100;
lbl.BackColor = System.Drawing.Color.BlanchedAlmond;
lbl.Text = TextBoxName.Text + "" + TextBoxStart.Text + "" + TextBoxEnd.Text;
e.Cell.Controls.Add(lbl);
}
}
}
}
else
{
}
}
Please help someone

Ok, once again from the start. Now I think I got it. Your problem is probably caused by comparing date with time to date. To get only date without time You can use dt.Date as You can see below. You can consider loading all data on page load because of performance reasons.
DataSet ds = new DataSet();
protected void Page_Load(object sender, EventArgs e)
{
//get data
using (SqlConnection connection = new SqlConnection(connectionString))
{
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand =
new SqlCommand("select * from event", connection);
adapter.Fill(ds);
}
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
//mark dates in calendar
foreach (DataRow dr in ds.Tables[0].Rows)
{
DateTime dt = (DateTime)dr.Field<DateTime?>("eventstart");
if (e.Day.Date == dt.Date)
{
e.Cell.BackColor = System.Drawing.Color.Yellow;
//add event lable to day
Label lbl = new Label();
lbl.BorderColor = System.Drawing.Color.Black;
lbl.BorderStyle = BorderStyle.Double;
lbl.BackColor = System.Drawing.Color.BlanchedAlmond;
lbl.Text = "Event text";
e.Cell.Controls.Add(lbl);
}
}
}
